| 00:08 | <Soopaman> | what does that do? |
| 00:09 | <Soopaman> | Chutt, you around? |
| 00:09 | <Soopaman> | vektor, you may be able to help me with it also |
| 00:13 | <Soopaman> | in order to "optimize" your tvtime or mythtv for a mpeg2 hardware tv tuner card, would the optimizations be in the application, or the linux device drivers |
| 00:13 | <mdz_> | Soopaman: optimizations? |
| 00:14 | <mdz_> | Soopaman: you mean besides writing support for a hardware encoder? |
| 00:15 | <vektor> | Soopaman: There's definitely something 'missing' in your question. |
| 00:15 | <vektor> | Do you have an MPEG2 hardware encoder card? |
| 00:18 | <Soopaman> | mdz, vektor, what i want to do is the tivo model |
| 00:18 | <vektor> | You have an MPEG2 encoder card? |
| 00:18 | <paperclip> | heh |
| 00:18 | <Soopaman> | of taking all video encoding/decoding routines off the cpu and onto the card |
| 00:19 | <vektor> | Using what hardware? |
| 00:19 | <Soopaman> | vektor, in a few weeks i will have one |
| 00:19 | <vektor> | Which one? |
| 00:19 | <vektor> | Are you writing a driver for it? |
| 00:19 | <paperclip> | i think your best be would be something like the buz =) |
| 00:19 | <Soopaman> | it's NDA |
| 00:19 | <Soopaman> | the buz? |
| 00:19 | <vektor> | He means the Iomega buz. |
| 00:19 | <paperclip> | external device.. |
| 00:19 | <vektor> | Obsolete hardware mjpeg encoder. |
| 00:19 | <paperclip> | obsolete? |
| 00:19 | <vektor> | Does iomega even exist anymore? |
| 00:20 | <Soopaman> | oh |
| 00:20 | <paperclip> | yeah.. |
| 00:20 | <Soopaman> | heheh |
| 00:20 | <vektor> | I thought those were unavailable except from ebay. |
| 00:20 | <paperclip> | they do sans and the new zip 750mb |
| 00:20 | <vektor> | Yeah but no more buz. |
| 00:20 | <paperclip> | mabye so.. |
| 00:20 | <vektor> | Anyway. |
| 00:20 | <Soopaman> | so... |
| 00:20 | <vektor> | Soopaman: So, you're writing a driver for a hardware encoder board? |
| 00:20 | <paperclip> | doesn't mean it's not a viable hardware capture solution.. |
| 00:21 | <vektor> | paperclip: Not if I have to find one used. |
| 00:21 | <Soopaman> | vektor, no they have one |
| 00:21 | <Soopaman> | for linux |
| 00:21 | <paperclip> | what about the matrox boards.. |
| 00:21 | <vektor> | Soopaman: And so you're writing support in mythtv for it? |
| 00:21 | <paperclip> | i don't know if they sell them with mjpeg anymore.. |
| 00:21 | <Soopaman> | i was wondering |
| 00:22 | <Soopaman> | can't a brother ask questions without getting the 3rd degree? |
| 00:22 | <Soopaman> | :P |
| 00:22 | <bigguy> | heh |
| 00:22 | <Soopaman> | "hypothetically" |
| 00:22 | <vektor> | I'm just curious. |
| 00:22 | <vektor> | Because your question sort of implied something existed. |
| 00:22 | <vektor> | And I was wondering if it did. :) |
| 00:22 | <Soopaman> | heheh |
| 00:22 | <Soopaman> | in due time |
| 00:23 | <Soopaman> | but could you answer the question mr president? :P |
| 00:23 | <vektor> | 'Optimization' means you have something and make it faster. |
| 00:23 | <vektor> | I don't understand the question. |
| 00:24 | <Soopaman> | what would it take to take the software mpeg2 encoding/decooding in mythtv/tvtime off of the cpu, and onto the gfx card |
| 00:24 | <vektor> | Is your question "what could mythtv do to get better performance with a hardware mpeg encoder board if i had a hardware mpeg encoder board and it had some drivers and if mythtv used those drivers"? |
| 00:24 | <vektor> | Oh. |
| 00:24 | <vektor> | So your question is "what would it take for mythv to support an extern mpeg2 encoder"? |
| 00:24 | <Soopaman> | kinda, but use it exclusively |
| 00:24 | <vektor> | tvtime does no encoding or decoding, we do processing on the raw video stream, so we can't work with MPEG. |
| 00:25 | <vektor> | Hardware MPEG decoders suck too because then I can't draw an OSD onto it. |
| 00:25 | <vektor> | Well unless they provide some OSD API, and I guess most kinda do. |
| 00:25 | <vektor> | But the drivers would have to support that too. |
| 00:25 | <paperclip> | heh.. |
| 00:25 | <vektor> | Dunno. |
| 00:25 | <paperclip> | what's up with mjpeg? same? |
| 00:25 | <vektor> | Difficult question to answer without knowing more about what the hardware is capable of doing. |
| 00:26 | <vektor> | paperclip: MJPEG isn't well standardized and kinda depends on your card. MJPEG just seems to be video frames with JPEG compression on them, no inter-frame compression. But I don't know much about it. |
| 00:26 | <Soopaman> | just theoretics |
| 00:28 | <paperclip> | which mpeg2 boards work with linux? |
| 00:28 | <paperclip> | i can only find mpeg1 and mjpeg |
| 00:28 | <vektor> | paperclip: Encoder or decoder? |
| 00:30 | <bigguy> | wow |
| 00:30 | <paperclip> | both =) |
| 00:30 | <paperclip> | i'd also prefer a hardware solution =) |
| 00:30 | <vektor> | There's the dxr2 and dxr3 cards which have some drivers. There was also a guy I met who did a driver for a PCMCIA hardware MPEG decoder. |
| 00:31 | <paperclip> | hmm.. |
| 00:31 | <vektor> | The nVidia binary drivers support hardware-assisted MPEG decoding using XvMC apparently. |
| 00:31 | <paperclip> | well. that's out.. =) |
| 00:31 | <paperclip> | so there are no encoders, eh? |
| 00:31 | <vektor> | Well. |
| 00:31 | <vektor> | there's this kfir chip that's in some european card. |
| 00:31 | <vektor> | It's apparently working. |
| 00:32 | <vektor> | And some guys I met were doing a PVR driver. |
| 00:32 | <vektor> | But I don't know how far they got. |
| 00:32 | <vektor> | Like the WinPVR or whatver. |
| 00:32 | <vektor> | There was some other code for that around. |
| 00:32 | <vektor> | Again, it was sort of kinda half somewhere in June but I don't know how much further they got. |
| 00:33 | <paperclip> | hmm.. my ultimate platform would be some of the new mini-ITX stuff coming out with a hardware encoder/decoder |
| 00:34 | <paperclip> | they are small/quiet/efficient |
| 00:35 | <paperclip> | aren't the athlon based mythTV boxes loud? |
| 00:35 | <bigguy> | nope |
| 00:36 | <bigguy> | just depends on your cooling |
| 00:37 | <bigguy> | couple of panaflo L1A 120's and a single 80mm on the hs running at 7v shouldn't be noticeable |
| 00:38 | <bigguy> | course my workstation is loud as heck only because I have a delta HO 80mm on the heatsink |
| 00:38 | <bigguy> | 80 something cfms of coolness |
| 00:38 | * aw | is hoping for something like paperclip is after... don't want all that extra heat in the stero cabinet even if it is quiet |
| 00:38 | <paperclip> | hmm.. still putting off loads of heat.. which means it's eating tons of power.. |
| 00:39 | <paperclip> | for a device that's supposed to be on 24/7 that's not so hot... |
| 00:39 | <aw> | the epia-m that's coming out claims it has decoding, dunno what linux support is though |
| 00:39 | <bigguy> | aw: there is no support for it YET |
| 00:39 | <aw> | figured |
| 00:39 | <paperclip> | i wonder about that too.. |
| 00:40 | <bigguy> | I have a nice case to put my pvr in got room for a 120mm fan + rad at the front |
| 00:40 | <aw> | seem like a tulatine based celron w/ micro atx is about as small/cool as you can get right now |
| 00:40 | <bigguy> | using a laptop dvd and laptop hdd for the boot drive |
| 00:41 | <bigguy> | and a nice 20x4 VFD :) |
| 00:41 | <paperclip> | aren't the p4's pretty good with power? |
| 00:41 | <aw> | not according to their datasheet |
| 00:41 | <dmz> | p4's suck a good bit of power |
| 00:41 | <dmz> | they just dont fry |
| 00:41 | <paperclip> | i thought they were in the 40w area |
| 00:41 | <bigguy> | the newer p4's ary about on par with the xp's |
| 00:42 | <paperclip> | what's the tulatine using? |
| 00:42 | <aw> | a C3 would be nice, but I doubt they can cut it w/o hw encode/decode, can anyone confirm? |
| 00:42 | <dmz> | paperclip: like 20w |
| 00:42 | <aw> | @900MHz - 26W; @1.4GHz - 35W |
| 00:42 | <bigguy> | c3 900 is about the same as a cel450 or 500 |
| 00:43 | <dmz> | aw: for a tualatin? i thought it was a bit less than that |
| 00:43 | <paperclip> | aw: i don't think they can.. they barely do dvd without hardware.. |
| 00:43 | <aw> | dmz: just printed out that page of the datasheet... |
| 00:44 | <paperclip> | i have an epia-5000 (533mhz) it's silent.. |
| 00:44 | <paperclip> | the only moving parts are the buttons on the front of the case.. |
| 00:45 | <paperclip> | linitx.org has/is a forum for linux/mini-ITX stuff |
| 00:46 | <dmz> | i wish i could get heatpipes |
| 00:46 | <paperclip> | quite a few there are struggling with dvd playback.. |
| 00:47 | <aw> | some friends just got a couple epia-5000s, they are _really_ cool boards |
| 00:47 | * aw | wishes they were faster |
| 00:48 | <paperclip> | PXE boot is nifty |
| 00:48 | <dmz> | in my experience fans are alright if you keep them under 2000 rpm |
| 00:49 | <dmz> | pabst has some either 1200 or 1500rpm one |
| 00:49 | <dmz> | thats rated 12dba |
| 00:51 | <paperclip> | still all that "silent" gear is spendy.. |
| 00:51 | <dmz> | http://www.plycon.com/fans/papst80_12dba.htm |
| 00:51 | <paperclip> | may as well cough up for a hardware solution.. |
| 00:51 | <paperclip> | =) |
| 00:53 | <aw> | the zalman "flower" heatsinks are quite a bit cheaper than I remember... assuming they fit in a tiny case |
| 00:54 | <paperclip> | zalmans are nice.. |
| 00:54 | <dmz> | i guess you could alway water cool everything |
| 00:54 | <dmz> | always |
| 00:54 | <paperclip> | yeah.. but that's even more money =) |
| 00:55 | <dmz> | i guess i need to make the first water cooled psu |
| 00:55 | <aw> | and a pump to keep quiet |
| 00:55 | <dmz> | a good pump is the expensive part |
| 00:55 | <dmz> | about $200 |
| 00:55 | <dmz> | for one that will last forever |
| 00:56 | <paperclip> | so what do you figure the cheapest "usable" mythtv box to be? |
| 00:56 | <paperclip> | ~$500 ? |
| 00:58 | <mdz_> | a water cooled psu sounds like an accident waiting to happen :-) |
| 00:58 | <paperclip> | aren't there non-conductive fluids.. |
| 00:58 | <dmz> | mdz: i did a watercooled pentium before it was "cool" to do it |
| 00:58 | <paperclip> | well.. electrically conductive.. |
| 00:59 | <dmz> | DI water |
| 00:59 | <dmz> | but you cant really run that in metal pipes |
| 01:00 | <dmz> | it eats them |
| 01:00 | <dmz> | alcohol maybe |
| 01:00 | <paperclip> | hmm.. works in my pipes.. |
| 01:01 | <dmz> | paperclip: ultrapure water has a tendency to eat metal |
| 01:01 | <paperclip> | i ment alcohol |
| 01:01 | <paperclip> | for my pipes =) |
| 01:02 | <dmz> | if i ever did a watercooled system all the pipes would be brazed |
| 01:02 | <paperclip> | that's a weird thing.. |
| 01:02 | <dmz> | copper |
| 01:03 | <dmz> | even if you fuckup nothing can leak from that |
| 01:04 | -!- | bigguy [] has quit [Read error: 113 (No route to host)] |
| 01:04 | <paperclip> | are you running mythtv? |
| 01:04 | <dmz> | not yet |
| 01:05 | <paperclip> | i'm really curious what sort of hardware ppl are using.. |
| 01:05 | -!- | bigguy [bigman@h31.44.102.166.ip.alltel.net] has joined #mythtv |
| 01:05 | <dmz> | yea, there needs to be a list of working hardware |
| 01:05 | <dmz> | or something |
| 01:05 | -!- | OrangeSun [] has quit [Read error: 104 (Connection reset by peer)] |
| 01:05 | <paperclip> | yeah.. something.. |
| 01:06 | <bigguy> | argh |
| 01:06 | <bigguy> | I have a tualatin cel 1.2 but I dunno about its pvr capabilities |
| 01:06 | <aw> | 1.4GHz T-bird here, too big/noisy/hot, but it works |
| 01:06 | <bigguy> | Well I was going to build a 1600+ based machine |
| 01:07 | <bigguy> | just need a mobo |
| 01:07 | <paperclip> | i'm just looking at cost/cost to operate vs. cost to buy better hardware.. |
| 01:07 | <bigguy> | but I have a new cel 1.2 and mobo |
| 01:07 | <bigguy> | just dunno if the cel has enough power to do it |
| 01:07 | <paperclip> | _shad was using a p2/350 for low quality video.. |
| 01:07 | <paperclip> | dunno how well.. |
| 01:08 | <bigguy> | hmm |
| 01:08 | <Chutt> | bigguy, should run decently enough |
| 01:08 | <Chutt> | 480x480 with good quality video, at the least |
| 01:09 | <bigguy> | got 1 gig of pc133 to go in it also but dunno how much of a difference that makes on pvr |
| 01:09 | <Chutt> | fast ram helps =) |
| 01:09 | <Chutt> | but that much doesn't relly make much of a difference, really |
| 01:09 | <paperclip> | what is fast? |
| 01:09 | <Chutt> | ddr |
| 01:09 | <paperclip> | mkay |
| 01:09 | <dmz> | rdram |
| 01:09 | <Chutt> | rdram would be even better |
| 01:10 | <bigguy> | well the board I have only takes pc133 and I'm not buying another board |
| 01:10 | <dmz> | intel needs to hurry with their new chipsets |
| 01:10 | <bigguy> | the proc was given to me unused by my uncle |
| 01:10 | <paperclip> | try it.. i'd like to know how well it works =) |
| 01:11 | <bigguy> | he was gonna use it in his sons comp but his son wanted a 2000+ machine like mine |
| 01:11 | <bigguy> | heh |
| 01:12 | <bigguy> | How to make a SFF machine into a leaf blower |
| 01:12 | <bigguy> | http://www.2cooltek.com/minisys.html |
| 01:12 | <aw> | anybody know if tv-out on the savage4 works? |
| 01:12 | <bigguy> | hmm |
| 01:12 | <paperclip> | aw: you thinking about the new epia? |
| 01:13 | <bigguy> | I have a couple of cards with tv out one is a trident based and the other is a radeon 7000 DDR 64meg |
| 01:13 | <aw> | no, was looking at the shuttle sv25... a cube is not my first choice, but I don't know where I'm gonna find low-profile plates for cards |
| 01:13 | <bigguy> | anyone know about the tv out support on the radeon 7000 in linux? |
| 01:14 | <aw> | nope, have some at work, but I've never tried tv-out |
| 01:14 | <bigguy> | k |
| 01:14 | <paperclip> | bigguy: gatos.sf.net |
| 01:16 | <bigguy> | paperclip: hmm that looks like its just for using the tv in stuff |
| 01:17 | <paperclip> | bigguy: i thought they listed the tvout stuff with the status for each card.. |
| 01:18 | <bigguy> | hmm |
| 01:18 | <bigguy> | see AIW cards listed but not a regulare 7000 |
| 01:19 | <bigguy> | course there wasn't a 7000 AIW to my knowledge |
| 01:19 | <paperclip> | ahh.. |
| 01:19 | <paperclip> | this may help.. "To enable TV-out: connect your TV to the computer. Turn the computer on, or, if it was running, reboot it." |
| 01:19 | <paperclip> | most likely the same.. |
| 01:20 | <bigguy> | I know in XP with the drivers I have you can use the tv as a second monitor |
| 01:21 | <paperclip> | dunno.. i'm pretty sure the trident is either/or in linux.. |
| 01:21 | <paperclip> | like that helps =) |
| 01:22 | <bigguy> | well its a pci card never used it tho |
| 01:22 | <bigguy> | it has a jumper on it for vga or tv tho |
| 01:22 | <aw> | tv-out on the sv25 appears to be controlled by the bios, so I'd guess it's invisible where it's going |
| 01:24 | <bigguy> | I have 2 tv cards also one is a wintv go mono bt878 and the other is a STB bt848 card |
| 01:24 | <bigguy> | dunno if the stb is stereo or mono |
| 01:29 | <paperclip> | what's dbx Stereo mean anyway.. |
| 01:29 | <paperclip> | i see that on some wintv cards.. |
| 01:32 | <bigguy> | wish whoeve had this stb card before me had left the stickers on it so I could find the model |
| 01:33 | <aw> | paperclip: so the shuttle cube looks like a good starting point, that comes to ~$270 (w/ 1.1GHZ Celeron & Zalman)... add tv card, mem, disk, etc... |
| 01:33 | <paperclip> | is there an FCC id on those things.. |
| 01:33 | <paperclip> | aw: not too shabby.. that's a nice looking box.. |
| 01:34 | <bigguy> | 1X0-0451-001 I think |
| 01:35 | <paperclip> | http://www.fcc.gov/oet/fccid/ |
| 01:37 | <paperclip> | i don't think that's a valid/whole number |
| 01:40 | <bigguy> | stb tvi30 with Temic tuner |
| 01:40 | <paperclip> | coo |
| 01:40 | <paperclip> | l |
| 01:40 | <paperclip> | =) |
| 01:42 | <bigguy> | but I don't find much info :( |
| 01:42 | <paperclip> | http://www.mail-archive.com/video4linux-list@redhat.com/msg03233.html |
| 01:42 | <bigguy> | looks like it was an oem for gateway |
| 01:43 | <paperclip> | yeah.. |
| 01:43 | <bigguy> | saw that one |
| 01:43 | <paperclip> | which == sux |
| 01:45 | <bigguy> | its old and out dated |
| 01:48 | <paperclip> | yeah.. the wintv 401 looks like the "better" bttv board.. |
| 01:48 | <paperclip> | with fm and dbx stereo .. whatever that is.. |
| 01:48 | <bigguy> | wow |
| 01:49 | <bigguy> | The wintv go I have has btaudio support it looks like |
| 01:50 | <paperclip> | is that good? |
| 01:51 | <bigguy> | yeah means I don't need the soundcard line in to record |
| 01:52 | <paperclip> | oh.. |
| 01:52 | <paperclip> | i wonder if the 401 has that? |
| 01:52 | <bigguy> | uses a conexant Fusion 878A chip which is basicly a bt878 |
| 01:54 | <bigguy> | hmm |
| 01:55 | <bigguy> | paperclip: can't find any info but I think that may be the same card as Chutt's |
| 01:55 | <bigguy> | could be wrong tho |
| 01:56 | <paperclip> | hmm.. |
| 01:56 | <bigguy> | whats wintv's official name for it? |
| 01:56 | <bigguy> | WinTV Radio? |
| 01:57 | <bigguy> | yeah |
| 01:58 | <bigguy> | 401 is the same as what Chutt has |
| 01:58 | <bigguy> | and it has btaudio support |
| 01:59 | <paperclip> | cool |
| 01:59 | -!- | yebyen is now known as chichimonkey |
| 01:59 | <paperclip> | have a look at this.. http://www.mail-archive.com/video4linux-list@redhat.com/msg03360.html |
| 01:59 | <bigguy> | but he said "Only the digital output seems to work, at 32kHz, stereo, 16bit." |
| 01:59 | <paperclip> | hmm.. |
| 02:00 | -!- | chichimonkey is now known as yebyen |
| 02:00 | <paperclip> | i don't have any digital stuffs.. |
| 02:00 | <paperclip> | audio stuffs that is.. |
| 02:00 | <Chutt> | the digital dsp device. |
| 02:02 | <bigguy> | Chutt your pvr machine also your workstation/developer box? |
| 02:03 | <Chutt> | yeah |
| 02:03 | <bigguy> | ok |
| 02:03 | <bigguy> | I might just put that tv card back in here then |
| 02:03 | <Chutt> | it's so much faster than the box i was using for work, i just use it for it, too |
| 02:03 | <bigguy> | need to clear off some of my drives |
| 02:03 | <paperclip> | interesting that they have the winpvr 250 drivers for linux now |
| 02:04 | <bigguy> | how good is the deinterlacing in myth? |
| 02:04 | <Chutt> | ever used mplayer's linear blend filter? |
| 02:04 | <bigguy> | the dscaler program sucks butt on windows |
| 02:05 | <bigguy> | Chutt: no |
| 02:05 | <Chutt> | ah, well, same as that. |
| 02:05 | <paperclip> | heh |
| 02:05 | <bigguy> | I have too many cards in this box |
| 02:06 | <paperclip> | Chutt: did you see this -> http://www.mail-archive.com/video4linux-list@redhat.com/msg03360.html |
| 02:06 | <bigguy> | modem,ata133,scsi,wintv go all pci |
| 02:07 | <Chutt> | paperclip, you'll also notice that no-one ever says they work :p |
| 02:07 | <paperclip> | Chutt: well.. they've only been out for 2 weeks or so.. |
| 02:07 | <Chutt> | they're not drivers for the card. |
| 02:07 | <paperclip> | well.. actually since 7/2/2002 |
| 02:07 | <paperclip> | for the mpeg2 encoder.. |
| 02:08 | <paperclip> | on the card.. |
| 02:08 | <Chutt> | they're not redistributable, either |
| 02:08 | <paperclip> | oh? |
| 02:08 | <Chutt> | so, no go. |
| 02:08 | <bigguy> | got 2 60 gigs in raid 0 on the onboard raid (dunno how well this raid chipset works in linux) got a 30gig,cdrw,20gig,and 12gig on the onboard ide and a 80 gig on the ata133 card |
| 02:08 | <paperclip> | you distribute drivers for other cards? |
| 02:09 | <bigguy> | dvd in this machine is a 4x scsi |
| 02:10 | <bigguy> | Chutt: you using the raid in linux? |
| 02:10 | <Chutt> | nope |
| 02:10 | <bigguy> | man |
| 02:10 | <Chutt> | just got a single 80 gigger in there for now |
| 02:12 | <bigguy> | been using the 2x60gig raid0 for dvd rips copy several over at a time and the transcode them to divx at my leisure |
| 02:15 | <bigguy> | any clue as to how much the multiple cards on the pci bus will mess with the tv capture? |
| 02:16 | <paperclip> | not much... IIRC some of the wintv stuff list a p90 as a requirement.. |
| 02:16 | <paperclip> | dma busmastering.. |
| 02:18 | <paperclip> | damn.. there are nda notices all over these docs.. |
| 02:18 | <paperclip> | for the itvc15 |
| 02:20 | <paperclip> | this stuff must be used in some linux based product.. |
| 02:21 | <paperclip> | they spent waaay too much time on these docs.. |
| 02:24 | <bigguy> | well as soon as this compressabilty test finishes and I setup the encode on these movies I am going to bed so I'm gonna go ahead and get off irc and such so I won't get pulled into more conversation ;) |
| 02:24 | <bigguy> | later |

| 14:07 | <sefudier> | hey guys.. what kind of system is needed to do 640x480 and above in mythtv ? |
| 14:08 | <nevertheless> | my athlon 800 takes 480 rtjpeg compression with about 95%cpu |
| 14:09 | <sefudier> | ic.. i wonder if a athlon 1.2 would be able to do 640x480 ? |
| 14:09 | <sefudier> | is it possible to do higher resolutions? or is that the max |
| 14:11 | <nevertheless> | i think, you can do more than that, but unfortunatly Im new to mythtv, too. today was the first day I got it really working... |
| 14:11 | <nevertheless> | but very soon Ill buy a new little xp 1700+ or so and run it on that |
| 14:21 | <sefudier> | ok |
| 14:21 | <sefudier> | to fill my database |
| 14:21 | <sefudier> | i have to run mythfilldatabase, then mythfilldata? |
| 14:21 | <sefudier> | there's no mythfilldata in my system |
| 14:22 | <nevertheless> | now, just do mythfilldatabase |
| 14:22 | <nevertheless> | where do you have the idea about mythfilldata? |
| 14:22 | <sefudier> | README |
| 14:22 | <sefudier> | once you run mythfilldatabase |
| 14:23 | <sefudier> | does it take some time running? |
| 14:23 | <sefudier> | or is it instanteneous |
| 14:23 | <nevertheless> | it takes some time, about 30 seconds on a german 7 day setup using about 30 channels |
| 14:24 | <sefudier> | ok, thanks |
| 14:24 | <nevertheless> | probably this is a typo in the READMY |
| 14:24 | <nevertheless> | README ;-) |
| 14:24 | <paperclip> | how does 480x480 look ? |
| 14:25 | <paperclip> | I'm curious how it compares to some commercial PVRs.. |
| 14:25 | <nevertheless> | ok, my tv-card only supports 384x288, so it wouldn't do anything goin higher |
| 14:25 | <paperclip> | which card is that? |
| 14:26 | <nevertheless> | a haupauge pci card |
| 14:26 | <paperclip> | really.. |
| 14:26 | <paperclip> | I'm about to bid on some model 401's |
| 14:26 | <paperclip> | that's the wintv-radio unit |
| 14:27 | <nevertheless> | yes, I think Im going to buy a new one too, so that I have two cards, since the one Im using now, is only mono |
| 14:28 | <paperclip> | is yours really old? |
| 14:28 | <nevertheless> | I bought it used, its maybe 3 of 4 years old |

| 14:55 | <sefudier> | you must have named your source some other name? |

| 14:56 | <nevertheless> | no |
| 14:56 | <nevertheless> | no, just .mythv/channels/ |
| 14:56 | <sefudier> | really? |

| 14:57 | <sefudier> | do ou have any files in .mythtv? |

| 14:59 | <paperclip> | oh.. they did that? |
| 14:59 | <sefudier> | arg.. i wonder how tthe hell should my parser output the info in xml for mythfilldatabase to accept it |
| 14:59 | <nevertheless> | sefudier: what? |
| 15:00 | <nevertheless> | paperclip: yes, they try to make it as easy as possible for ex M$ |
| 15:00 | <paperclip> | nevertheless: heh.. i'm used to debian which is quite the opposite =) |
| 15:02 | <nevertheless> | SuSE was really nice for me comming from windows some (...) time ago and friends of mine used it, but after realizing, that updating is almost unpossible, and i switched to gentoo |
| 15:02 | <nevertheless> | debian is the system my router will run, soo |
| 15:02 | <nevertheless> | n |
| 15:03 | <paperclip> | yeah.. i'm using debian for production stuff.. and gentoo for desktop/fun |
| 15:04 | <mdz_> | nevertheless: that file should have been created when you initally set up your channels |
| 15:04 | <paperclip> | i plan on checking out the BSDs tho for the production side aswell.. |
| 15:04 | <mdz_> | nevertheless: when you ran mythfilldatabase --manual |
| 15:04 | <nevertheless> | paperclip: what do you mean with "production" ? |
| 15:05 | <paperclip> | nevertheless: stuff i don't want to break.. |
| 15:05 | <nevertheless> | mdz_ all is just saved in the db |
| 15:05 | <nevertheless> | ah, ok |
| 15:05 | <paperclip> | stable/solid |
| 15:05 | <paperclip> | gentoo is frail |
| 15:05 | <vektor> | That's putting it lightly. |
| 15:05 | <paperclip> | it's so fun tho.. |
| 15:06 | <paperclip> | anyone use the remote that comes with the Hauppage cards? |
| 15:06 | <nevertheless> | right :-) |
| 15:06 | <paperclip> | does it have an ir dongle ? |
| 15:07 | <nevertheless> | i use the remote, that came with a pinnacle card |
| 15:07 | <paperclip> | where'd you get the ir thingy? |
| 15:07 | <nevertheless> | the reciever? |
| 15:08 | <paperclip> | yes |
| 15:08 | <nevertheless> | it was in the package, too, its for serial connector |

| 15:12 | <paperclip> | i don't know for sure.. |
| 15:13 | <paperclip> | but it sounds like some windows stupidness.. |
| 15:13 | <paperclip> | do you read the mailing list? |
| 15:13 | <mdz_> | nevertheless: the channel definitions that mythtv uses are saved in the db |
| 15:13 | <mdz_> | nevertheless: but the xmltv configuration is stored in that file |
| 15:13 | <mdz_> | nevertheless: you need it |
| 15:14 | <sefudier> | mdz plz help me :) |
| 15:14 | <nevertheless> | I definitly don't have it... is it the same on a german setup? |
| 15:14 | <sefudier> | what are the contents of the .mythtv/default.xmltv after you run the setup utility ? |
| 15:15 | <sefudier> | can you send me yours pls, mdz? |
| 15:18 | <nevertheless> | I asked this question before (and I will go on to askit ;-)), but again, is there any chance running mythtv on a xinerama setup on only one monitor, not spreaded over all? |
| 15:18 | <Chutt> | the default.xmltv depends on your grabber, where you're located, and what channels and all that |
| 15:18 | <Chutt> | it's the xmltv config file, it can't be shared :p |
| 15:18 | <Chutt> | nevertheless, hit 'f' |
| 15:18 | <Chutt> | and it'll go to a window |
| 15:19 | <Chutt> | if someone wants to add xinerama support, they're welcome to |
| 15:19 | <sefudier> | chutt yes i know |
| 15:19 | <sefudier> | thats exactly what i need to find out |
| 15:19 | <sefudier> | the format of the file, because im coding a grabber for my local tv (brasil) |
| 15:19 | <Chutt> | it doesn't matter what the format is |
| 15:19 | <sefudier> | i've made the part of the /tmp/myth* |
| 15:19 | <Chutt> | it's entirely internal to the grabber |
| 15:19 | <sefudier> | yeah, i need to know what the hell is in that file |
| 15:20 | <Chutt> | any configuration that the grabber needs |
| 15:20 | <sefudier> | ok, here's the situation: i;ve coded the grabber, which works with mythfilldatabase, and it creates all those /tmp/myth* when requested by mythfilldatabase |
| 15:20 | <mdz_> | sefudier: tv_grab_na stores the zip code, provider ID number, channels which are selected for grabbing, etc. |
| 15:20 | <sefudier> | the format of my /tmp/myth* is exactly the same as the ones generated by tv_grab_na |
| 15:21 | <nevertheless> | Chutt: thx :-) |
| 15:21 | <sefudier> | now i need to know wtf is stored in .myth/default.xmltv generated by tv_grab_na |
| 15:21 | <mdz_> | sefudier: mythtv doesn't care about the grabber config |
| 15:21 | <sefudier> | cause just with the /tmp/myth* its not working.. the mysql database arent geting populated |
| 15:21 | <mdz_> | sefudier: so if you need to store some data, put it in that file, otherwise you don't need it |
| 15:22 | <sefudier> | ic |
| 15:22 | <Chutt> | sefudier, if it's not getting populated, then the format of the xml output isn't right. |
| 15:23 | <Chutt> | well, it could be following the dtd, but filldatabase isn't understanding it |
| 15:25 | <sefudier> | humm |
| 15:25 | <sefudier> | what is that parameter --offset? |
| 15:25 | <mdz_> | sefudier: man tv_grab_na |
| 15:25 | <sefudier> | ok.. its just that i havent installed tv_grab_na |
| 15:26 | <sefudier> | too many perl dependencies |
| 15:26 | <mdz_> | sefudier: you haven't installed XMLTV? |
| 15:26 | <sefudier> | no |
| 15:26 | <paperclip> | he's trying to code something elsed to do it's job.. |
| 15:26 | <sefudier> | yes |
| 15:26 | <sefudier> | exactly |
| 15:27 | <mdz_> | sefudier: yes, but you should be using the XMLTV perl module to do it |
| 15:27 | <mdz_> | sefudier: if you want to be compatible |
| 15:27 | <mdz_> | but if you insist on doing it another way, you don't need to install any dependencies in order to read the documentation for xmltv |
| 15:28 | <sefudier> | well i just need to generate a text file in the same format |
| 15:28 | <sefudier> | i dont need several hundred kbytes of bloated code |
| 15:28 | <mdz_> | sefudier: is it in the same format? |
| 15:28 | <mdz_> | sefudier: did you validate it against the DTD? |
| 15:28 | <sefudier> | to parse an html file into an xmltv file |
| 15:29 | <paperclip> | what are you using? |
| 15:29 | <paperclip> | c |
| 15:29 | <sefudier> | yeah, pretty much the same format.. do you want to look at a sample? |
| 15:29 | <sefudier> | python |
| 15:29 | <paperclip> | =) |
| 15:29 | <mdz_> | sefudier: 'pretty much' may not be good enough |
| 15:30 | <mdz_> | sefudier: if you're not using the XMLTV code, you need to validate it to make sure that it is correct |
| 15:30 | <mdz_> | rxp should do it |
| 15:30 | <sefudier> | ic.. |
| 15:30 | <mdz_> | I believe sp will as well |
| 15:30 | <sefudier> | rxp is the program i need to use to validate it? |
| 15:30 | <mdz_> | I do not think that mythfilldatabase tries to validate it |
| 15:30 | <mdz_> | if it is wrong, then it will probably just not work |
| 15:30 | <mdz_> | sefudier: yes |

| 15:45 | <brunes> | second tv tuner is on the way |
| 15:45 | <nevertheless> | which ones? |
| 15:46 | <brunes> | which ones what? |
| 15:46 | <nevertheless> | which tuner cards? |
| 15:46 | <brunes> | two bttv cards |
| 15:46 | <nevertheless> | that is? |
| 15:46 | <brunes> | ? |
| 15:46 | <nevertheless> | i mean, that are? |
| 15:46 | <brunes> | what are you talking about |

| 15:47 | <OrangeSun> | paperclip: hehehehe. now you're on the right track.. |
| 15:47 | <brunes> | I have a bt848 card, and im getting a bt878 one |
| 15:47 | <OrangeSun> | Question: has anybody figured out a way for myth to start on the input that you want? (composite, for example) |
| 15:48 | <nevertheless> | don't they have names? no maker? |
| 15:48 | <brunes> | ones a phoebiemicro, I forget the other one |
| 15:48 | <brunes> | why? |
| 15:48 | <nevertheless> | just for the stats ;-) |
| 15:48 | <nevertheless> | Im just interested |
| 15:48 | <brunes> | the card maker doesnt matter so much as the chip |
| 15:49 | <OrangeSun> | man.. i can't believe how much space mythtv's videos can take up!! |
| 15:49 | <brunes> | yeah I know |
| 15:49 | <paperclip> | can you switch the bt8x8 cards inputs on the fly.. like if i have sat on s-vid and antenna on coax ? |
| 15:49 | <nevertheless> | thats quite right, but my pinnacle 848 does not work with my hauppauge 8x8 |
| 15:49 | <brunes> | I want ot find out about that |
| 15:50 | <OrangeSun> | paperclip: yeah.. with "c" |
| 15:50 | <paperclip> | OrangeSun: is that a keypress? |
| 15:50 | <OrangeSun> | paperclip: how can you switch them "not on the fly"? |
| 15:51 | <OrangeSun> | paperclip: yes. but skip the preceeding and tailing ' " ' (quotation mark) |
| 15:51 | <paperclip> | OrangeSun: i dunno if it can switch at all.. i'm totally new to tvcards.. |
| 15:51 | <OrangeSun> | seriously.. how can you pre-select the input it uses? cuz I haven't at all figured this out.. |
| 15:51 | <brunes> | WHy is it I can rip a DVD (704x304) at 1000 bps using mpeg4 libavcodec and it look sgreat, but with mythtv 1000 bps looks liekc rap |
| 15:51 | <brunes> | and the filessize is almost 2x larger |
| 15:52 | <paperclip> | anyone use the hauppage remote? |
| 15:52 | <brunes> | it makes no sense to me |
| 15:52 | <OrangeSun> | paperclip: well, they can be switched.. the question is one of whether or not the program can. |
| 15:52 | <brunes> | its the same library... should be the same size/quality |
| 15:52 | <OrangeSun> | brunes: ar eyou using mpeg4 or rtjpeg? |
| 15:52 | <brunes> | mpeg4 in both |
| 15:52 | <paperclip> | brunes: could it be the source? |
| 15:52 | <OrangeSun> | brunes: In that case, not sure.. |
| 15:53 | <brunes> | like, with mpeg4 in myth you basiclly have to use 2000+ bnps to have decent quality |
| 15:53 | <brunes> | I have never ever seena dvdrip with more than 1500bps |
| 15:54 | <brunes> | only difference I can see is the container format isnt avi |
| 15:54 | <mdz_> | brunes: wtf are you talking about? |
| 15:54 | <OrangeSun> | brunes: perhaps it has to do with the codec? while mythtv uses mpeg4, it uses a heavily modified nupelvideo codec.. |
| 15:54 | <mdz_> | brunes: surely you mean 1500kbps |
| 15:54 | <paperclip> | why would you expect TV to look like a DVD rip.. |
| 15:54 | <brunes> | mdz: Yes kbps sorry |
| 15:54 | <mdz_> | brunes: mythtv is doing it in real-time |
| 15:54 | <OrangeSun> | paperclip: digital inputs can look very good.. |
| 15:55 | <brunes> | mdz: so does my dvd encoding |
| 15:55 | <brunes> | does it at around 45 fps |
| 15:55 | <paperclip> | OrangeSun: digital inputs? |
| 15:55 | <mdz_> | brunes: what kind of CPU? |
| 15:55 | <brunes> | xp 1800 |
| 15:55 | <OrangeSun> | paperclip: satellite, for example. |
| 15:55 | <vektor> | brunes: Maybe you're not deinterlacing your video input. |
| 15:55 | <brunes> | vektor: how od I do that? |
| 15:56 | <vektor> | brunes: That can really screw your compression if it has to deal with the high frequency interlaced frames. |
| 15:56 | <mdz_> | brunes: you must be using different quality settings or a different encoder |
| 15:56 | <paperclip> | OrangeSun: but you would be using an analog signal, eh? |
| 15:56 | <brunes> | mdz: I us emencoder for dvd rippuing, which uses libavcodec with mpeg4.. same as myth |
| 15:56 | <brunes> | vektor: How do I enable de-interlacing? |
| 15:57 | <OrangeSun> | paperclip; huh? |
| 15:57 | <vektor> | brunes: I don't know. |
| 15:57 | <brunes> | # Playback options |
| 15:57 | <brunes> | # |
| 15:57 | <brunes> | # Deinterlace playback (1 for on, 0 for no) -- adds to CPU usage |
| 15:57 | <brunes> | int Deinterlace=1 |
| 15:57 | <sefudier> | ok, now it works.. |
| 15:57 | <brunes> | theres an option for playback but not encode |
| 15:57 | <paperclip> | OrangeSun: what sort of digital connection do you make between the sat receiver and the mythtv box? |
| 15:57 | <sefudier> | mdz: thx for the help |
| 15:58 | <OrangeSun> | paperclip: there are div. video outputs on satellite receivers.. optical whatnot. |
| 15:58 | <brunes> | I duno I just find that mythtv recordings seem to take an incredible amout of space. Do tivo recordings take simmilar space? They us empeg2 right? |
| 15:59 | <paperclip> | OrangeSun: not on any i've seen.. but you might be right.. so which capture card uses optical whatnot? |
| 16:00 | <OrangeSun> | paperclip: a) there are digital-output satellite receivers.. (http://www.audiorevolution.com/equip/sonyhd100/). b) some have firewire output. |
| 16:00 | <paperclip> | OrangeSun: heh.. looking.. |
| 16:00 | <OrangeSun> | now getting firewire into myth is a whole other story, as there aren't any v4l drivers.. |
| 16:01 | <vektor> | If mythtv doesn't deinterlace before encoding then your quality is bound to suffer if it's using a progressive encoder. |
| 16:01 | <paperclip> | OrangeSun: i'm amazed that the MPAA/ networks would allow such a port to exist on a digital sat box.. |
| 16:01 | <brunes> | vektor: well hwy isn't there an option to do that? |
| 16:01 | <OrangeSun> | I obviously run no such setup, though.. my point was that you can get a very crisp signal coming in from a source, and still have it treated not as well as if it were going straight to TV.. |
| 16:01 | <vektor> | brunes: In case you can't tell, I don't run mythtv, I'm just giving suggestions. |
| 16:02 | <brunes> | oh |
| 16:02 | <vektor> | brunes: I have no idea what mythtv does or does not do. |
| 16:02 | <brunes> | hrom what I see, it de-interlaces on playback |
| 16:02 | <OrangeSun> | http://www.jvc.com/pressbox/jsx777.htm |
| 16:02 | <brunes> | myth needs xinerama support badly as well |
| 16:02 | <vektor> | brunes: Then I think that might hurt you. It probably isn't too hard to hack it to deinterlace before encoding. You should try. |
| 16:03 | <nevertheless> | brunes: hehe, we just talked about this |
| 16:03 | <vektor> | brunes: I have some Xinerama code I use from ogle that you could port into mythtv. |
| 16:03 | <brunes> | nevertheless: xinerama? |
| 16:03 | <nevertheless> | but since mythtv is intended to run on a separate box, I think this is not too necessary |
| 16:03 | <nevertheless> | yep |
| 16:04 | <vektor> | brunes: Take a look at display.[h,c] in the ogle source tree. |
| 16:04 | <paperclip> | OrangeSun: that sat receiver has no digital output (that i can see) |
| 16:04 | <vektor> | brunes: under video_out. |
| 16:05 | <paperclip> | OrangeSun: the article even bitches that you can't get hdtv out to an hdtv vcr |
| 16:05 | -!- | rnc [~rnc@RJ227094.user.veloxzone.com.br] has joined #mythtv |
| 16:06 | <OrangeSun> | paperclip: oh well. you gotta be wrong sometime.. |
| 16:06 | <brunes> | if you did the de-interlacing beforehand, you wouldnt have to do it in playback |
| 16:06 | <OrangeSun> | on that note, I must disappear.. see you soon : ) |
| 16:06 | <vektor> | brunes: Correct. |
| 16:06 | <OrangeSun> | brunes: it deinterlaces on record. |
