10:30	<skitzo>	i accidentally ran into your thread on gatos and realized it was you
11:04	<mdz>	skitzo: are you schizo@d.o?
11:04	<skitzo>	no
11:05	<skitzo>	seth/oztiks
11:05	<skitzo>	if you remember our convo on uhh.. friday(?) in here
11:06	<mdz>	ah, ok. sorry, I'm bad with names
11:06	<skitzo>	no prob =P
11:06	<skitzo>	didnt expect you to remember me ;)
11:06	-!-	Universe [] has quit ["Client Exiting"]
11:06	<skitzo>	was just surprised to read your post in the gatos list
11:06	<skitzo>	heh
11:07	<mdz>	I was doing a lot with gatos for a while; not so much since I started playing with mythtv
11:07	<mdz>	which was about the same time I borrowed a real capture card
11:08	<mdz>	once vladimir implements that second Xv adapter using YUV textures like he has proposed, then I'll be able to get a lot more out of the card
11:08	<mdz>	I'm headed out for breakfast, later
11:11	<skitzo>	hmm
11:11	<skitzo>	ciao ciao

14:50	--> Syn-	(~hisyn@pcp01516112pcs.reding01.pa.comcast.net) has joined #mythtv
14:53	<OrangeSun>	if I run mythtv, is it the only thing my system will be able to run?
14:53	<OrangeSun>	or can I use my linux server to run it?
14:53	<OrangeSun>	or does that all depend? : )
15:46	<blinx>	good evening
15:50	<OrangeSun>	howdy
15:55	-!-	Echo465 [~Echo465@12-222-117-17.client.insightBB.com] has joined #mythtv
15:58	<blinx>	OrangeSun: it can run other stuff, but I guess you need to run mythtv fullscreen - atleast when using it, while recording and such, you could use the display for other things
15:58	<OrangeSun>	blinx: how can i output?
15:58	<OrangeSun>	blinx: Just use my video card's TV out?
15:59	<blinx>	I use a nvidia running in twinview - where my display is closed to the tv
15:59	<blinx>	cloned
15:59	<OrangeSun>	hmmm. is it easy to do that with nvidias?
16:00	<OrangeSun>	I wonder how easy it is with voodoos : )
16:00	<blinx>	yeah, was for me atleast :)
16:00	<OrangeSun>	what sort of system are you running? CPU wise?
16:00	<blinx>	athlon 1400
16:00	<OrangeSun>	hmm. would a duron 1000 do it?
16:01	<OrangeSun>	how much RAM?
16:01	<blinx>	256MB ddr - I have another 256mb - but they are not installed at the moment
16:01	<OrangeSun>	and it runs smoothly?
16:01	<OrangeSun>	oh, another q.. how does MythTV change channels??
16:02	<blinx>	yes - 1gig duron should be enough to record atleast - dunno about watching meanwhile
16:02	<OrangeSun>	I have a satellite, so I want it to change channels by executing a command that emits an IR something or other..
16:02	<blinx>	uhm.. I think there is something in the faq by that - else I guess it could be hacked to do it
16:02	<blinx>	I just have normal terrestial antenna
16:03	<OrangeSun>	terrestrial antenna?
16:03	<OrangeSun>	you receive like 3 channels?
16:03	<OrangeSun>	and you got yourself a PVR?
16:03	<blinx>	no.. well - it works like that - it's kind of a community antenna thingy, so we have sattelite tv too :)
16:04	<OrangeSun>	how does that work?
16:04	<blinx>	got 20 channels or so - 5 worth watching :)
16:04	<blinx>	OrangeSun: there is a central antenna for the city, and they have a few dishes too - and they then rebroadcasts it out on seperate channels.
16:04	<OrangeSun>	blinx: how much does a setup like that run? or is it professional?
16:05	<blinx>	it's professional, the city runs it
16:05	<OrangeSun>	what city?
16:05	<blinx>	the one I live in :)
16:05	<OrangeSun>	in denmark?
16:05	<blinx>	Nyk�bing Falster - Denmark :)
16:05	<blinx>	ye
16:05	<OrangeSun>	damn. you danes know your stuff..
16:05	<vektor>	Anyone here interested in trying my deinterlacer?
16:06	<blinx>	OrangeSun: would be even better if we had more than 5 danish channels :)
16:06	<blinx>	with digital sattelite reciever you can get alot more - but I can't have a sattelite dish where I live
16:06	<OrangeSun>	heheh : )
16:06	<vektor>	OrangeSun: If you're interested in TV output under Linux, you could check out my page: http://vektor.theorem.ca/graphics/tvout/
16:06	<OrangeSun>	where do you live? in an apt?
16:06	<blinx>	ye
16:06	<OrangeSun>	vektor: Ok, thanks.
16:07	<OrangeSun>	blinx: you can point through windows..
16:07	<vektor>	OrangeSun: But I'm mostly interested in near-professional quality TV output.
16:07	<blinx>	vektor: a better deinterlacer?
16:07	<blinx>	OrangeSun: ye - no windows face the right way :)
16:07	<OrangeSun>	vektor: you're making your own PVR?
16:07	<vektor>	blinx: My deinterlacer is its own app.
16:07	<blinx>	ah
16:07	<vektor>	OrangeSun: Yeah I did, kinda.
16:07	<vektor>	blinx: It's like a DScaler-port.
16:07	<OrangeSun>	is it at the level of myth?
16:07	<vektor>	No.
16:08	<vektor>	I've done a bunch of video applications though, I'm not really interested in the PVR like mythtv does.
16:08	<OrangeSun>	vektor: i have a quesiton..
16:08	<vektor>	I really want a high quality video recorder. Mine isn't really done though.
16:08	<OrangeSun>	can I use my DV input as a Video4linux thing?
16:08	<vektor>	But I did my own huffyuv-like lossless codec.
16:08	<vektor>	OrangeSun: Ah, good question.
16:09	<blinx>	I wish I'd get better picture too - gf refuses to watch mythtv live to cos it "looks different"
16:09	<OrangeSun>	vektor: good question because you've thought about it a lot and you have a 2-command answer for me? : )
16:09	<OrangeSun>	blinx: digital satellite looks different!!
16:09	<vektor>	OrangeSun: V4L could theoretically support it, I don't think any drivers do, but really you don't want DV decoding in the kernel, so I'm not sure what kind of card would support that.
16:10	<vektor>	OrangeSun: But I know I'm somewhat interested in doing DV input to my deinterlacer.
16:10	<vektor>	OrangeSun: However, do you know the quality problems with DV re:broadcast TV?
16:10	<vektor>	DV has half the colour resolution as broadcast TV.
16:10	<vektor>	So, it's not really very exciting.
16:10	<vektor>	blinx: You should try my deinterlacer.
16:11	<vektor>	blinx: However, the biggest problem I have with watching TV on a CRT is that my CRT is nowhere near as bright as my TV.
16:11	<OrangeSun>	vektor: well, I have no video capture card yet, and a DV camcorder.. so i just wanted to run mythtv or whatever through the camera..
16:11	<vektor>	OrangeSun: Reasonable goal, but I don't think (although I'm not sure) that there's any way to do that right now.
16:11	<OrangeSun>	I'm relatively sure you're right..
16:12	<OrangeSun>	I'm having a lot of trouble with the perl dependencies!
16:12	<vektor>	blinx: http://www.sf.net/projects/tvtime/
16:12	<vektor>	blinx: Grab it from CVS, tell me what you think. ;-)
16:12	<OrangeSun>	for eample, my attempt at installing Tk modules is not working.
16:12	<blinx>	ok - I'll take a look :)
16:12	<vektor>	blinx: Let me know if you're going to run it.
16:12	<vektor>	blinx: It's not an official release yet though.
16:13	<blinx>	ok..
16:13	<blinx>	gotta make dinner first :)
16:13	<vektor>	ok.
16:13	<vektor>	just msg when you're going to try.
17:16	<skitzo>	vektor: good look w/ your project
17:17	<skitzo>	err
17:17	<skitzo>	luck
17:24	<vektor>	skitzo: Have you tried it?
17:25	<skitzo>	no, but if you make any headway with it you'll have a supporter ;)
17:25	<vektor>	I think you should try.
17:25	<skitzo>	all i have right now is an older ATI card which makes me want to kill things.
17:25	<vektor>	Ok.
17:25	<vektor>	Have you ever used DScaler?
17:25	<skitzo>	no sir =)
17:25	<vektor>	ok.
17:26	<vektor>	Well anyway, tvtime pretty much works.
17:26	<vektor>	At least for basic stuff.
17:26	<vektor>	We already blow every TV viewing app under linux out of the water.
17:26	<skitzo>	hmm
17:27	<skitzo>	where is 'tvtime' ?
17:27	<vektor>	http://www.sf.net/projects/tvtime/
17:28	<skitzo>	cvs only i take it?
17:28	<vektor>	Yes.
17:28	<vektor>	As I mentioned, we haven't released yet.
17:28	<skitzo>	hmm
17:28	<skitzo>	what are y our long term goals/plans?
17:28	<vektor>	Have a full DScaler port.
17:28	<vektor>	But also, have a working pass-thru system.
17:29	<vektor>	So we can record and display to TV output without any loss of quality.
17:29	<skitzo>	yay
17:29	<vektor>	http://vektor.theorem.ca/graphics/tvout/
17:29	<vektor>	I have pass-thru working already.
17:29	<vektor>	field-correct.
17:29	<skitzo>	all form a g400?
17:29	<skitzo>	from
17:29	<vektor>	And only hte G400, for now :(
17:29	<vektor>	I have a bt848-based capture card.
17:29	<vektor>	And a G400 with TV output.
17:29	<skitzo>	ah
17:29	<skitzo>	whats the card?
17:30	<vektor>	I can do a 1-1 field-to-field correct pass-thru.
17:30	<vektor>	It's a Hauppauge WinTV.
17:30	<skitzo>	ah
17:30	<skitzo>	thoughts/comments on it?
17:30	<vektor>	I want this: http://www.sdisilk.com
17:30	<vektor>	That's all I have to say. :)
17:31	<vektor>	That will be my next card.
17:31	<vektor>	The WinTV has served me very, very well.
17:31	<skitzo>	OH MY GOSH
17:31	<vektor>	But I need something with component in next, or at least S-Video.
17:31	<skitzo>	where do i order ;)
17:31	<vektor>	Having full SDI input would kick though.
17:31	<skitzo>	heh
17:31	<vektor>	Have you seen the price though?
17:31	<vektor>	I'm saving up.
17:31	<skitzo>	pardon my ignorance, what does SDI actually stand for ;)
17:32	<vektor>	Serial Digital Interface.
17:32	<skitzo>	ahh
17:32	<vektor>	It's a digital video standard for broadcast.
17:32	<vektor>	So, full colour resolution.
17:32	<Echo465>	holy crap, $550.
17:32	<vektor>	Yep.
17:33	<vektor>	See, there's a real lack of hardcore quality videophiles who are also linux hobbyists.
17:33	<vektor>	So, Windows gets all the fun now.
17:33	<skitzo>	i have been denoting that for the past week =/
17:33	<skitzo>	ccant find diddly shit for leenux (hardware wise.. )
17:33	<skitzo>	its disappointing.
17:33	<vektor>	What do you mean by that?
17:33	<vektor>	What sort of hardware are you looking for?
17:34	<skitzo>	quality capture/TV out cards (w/ drivers)
17:34	<vektor>	The bttv driver supports everything windows supports, pretty much.
17:34	<vektor>	TV out for video is different.
17:34	<vektor>	I mean, DScaler is based on the linux driver :)
17:34	<skitzo>	hmm
17:39	<skitzo>	Yes. Satellite receivers can be modified to output SDI.
17:39	<skitzo>	oooooo
17:39	<vektor>	Yeah.
17:39	<vektor>	It's like component but digital.
17:40	<skitzo>	SDI-DTiVo DirecTiVo (Phillips, Sony, Hughes) SDI Upgrade $450.00
17:40	<skitzo>	wel there goes that. =)
17:40	<vektor>	You're no fun at all.
17:40	-!-	nyquiljer [jer@12.211.16.232] has joined #mythtv
17:40	<skitzo>	nah, sadly dont have that kinda spare change
17:40	<skitzo>	and im ore interested in modifying my other sat receivers anyhoo
17:43	<nyquiljer>	vektor: you around?
17:43	<vektor>	Yes.
17:44	<nyquiljer>	yay.
17:44	<nyquiljer>	I'm curious what the best way to go abou greating images using only colors that YUV can display
17:44	<nyquiljer>	creating
17:45	<nyquiljer>	I've been pretty unhappy with how things look after the yuv conversion, and I'm sure its because most of the colors I'm using are getting lost
17:45	<vektor>	Cool.
17:46	<vektor>	How are you converting to Y'CbCr?
17:46	<vektor>	You just letting mythtv do it?
17:46	<nyquiljer>	well, I'm not, chutt has a routine that does it
17:46	<nyquiljer>	yeh
17:46	* vektor	wonders how they do it.
17:46	<vektor>	Ok.
17:46	<vektor>	Is Chutt's routine doing the right conversion?
17:46	<vektor>	do you know where the routine is in the source?
17:46	<nyquiljer>	no idea
17:46	<vektor>	See, the first job is to make sure all of that is actually being done correctly.
17:46	<nyquiljer>	I have no idea, I know he 'found' it somewhere
17:47	<vektor>	cute.
17:51	<nyquiljer>	looks like its in /libs/libNuppelVideo/osd.cpp
17:54	<vektor>	sure doens't look like it
17:55	<vektor>	Looks like it's yuv2rgb.c
17:55	<nyquiljer>	yeh
17:55	<nyquiljer>	was just gonna say that
17:55	<vektor>	sure looks like it's the wrong transform
17:56	<vektor>	eww
17:56	<vektor>	i also think it's taking chroma samples in the wrong place
17:58	<vektor>	well
17:58	<vektor>	i'll give you a new function sometime
17:58	<nyquiljer>	well, assuming that it wa sin fact being done properly in code
17:58	<vektor>	i have a test tomorrow i need to study for
17:59	<vektor>	ok, assuming it was
17:59	<nyquiljer>	I assume I'd need to restrict my pallete right?
17:59	<vektor>	well, kinda..
17:59	<vektor>	if you're outputting to a TV, then yes.
17:59	<vektor>	Otherwise, not really....
17:59	<vektor>	Kinda.....
17:59	<nyquiljer>	gimp has a 'hot' filter that supposedly filters out anything too hot for ntsc
17:59	<vektor>	Yeah.
17:59	<nyquiljer>	but I don think thats entirely what I want
17:59	<vektor>	I'm not convinced you want to do that.
18:00	<vektor>	What is the problem you're seeing though?
18:00	<nyquiljer>	washed out
18:00	<vektor>	I mean, if you do the conversion right, and you're looking on a monitor, the original and the XVideo image should be _identical_.
18:00	<vektor>	Like, you may notice slight banding, but that's it.
18:00	<nyquiljer>	hmm, ok.
18:00	<vektor>	I think the 'washed out' effect is entirely due to this being the wrong transform.
18:00	<nyquiljer>	I'll just assume the problem is in that conversion
18:01	<vektor>	Since it uses the full 0-255 range for luma, and 0-255 for both chroma channels.
18:01	<skitzo>	well, someone please do patch it ;)
18:01	<vektor>	It should be using 16-235 for luma, and 12-240 for both chromas.
18:01	<vektor>	skitzo: maybe after my test.
18:01	<skitzo>	heh
18:01	<skitzo>	sounds good to me.
18:01	<vektor>	I already told Chutt about this and I told him I'd fix it sometime.
18:01	<skitzo>	ah
18:01	<skitzo>	cool cool
18:01	<skitzo>	alas he is on vacation now, too =/
18:02	<nyquiljer>	vektor: well you answered my question, thanks. good luck with your test :)
18:02	<vektor>	thanks.
18:02	<skitzo>	yeh, ditto, good luck
