Re: [mythtv-users] Playback vid corruption with 1080i (with pics)
I think that i've further narrowed down the problem. After bringing a different box downstairs and trying on the same display, I've learned a few things. -- If myth/myplayer outputs a 1080i signal at particular resolutions (such as 1680x1050) it will disort the output as described below. -- If other output resolutions are used it works great. Ie 1400x1050 works fine. The best way that I have found to play with this is to leave X at a res of 1680x1050, and use the appearance options in myth to try different resolutions. I haven't really tried very many, since i discovered this late last night. Now I wondering if the problem is with the wide screen (16:10) nature of the 1680x1050 resolution, or if it is just too high or something. I'd obviously like to run at 1680x1050 since that's the native resolution of the LCD, and also i would want it to be wide, since widescreen is obviously better. What can i do? Does anyone know why I can't use the correct resolution? Is there another resolution that would be close that might work? What can I try?

I see the following in the log file:

are you setting the output size differently than you're display
resolution? If so, then MythTV is probably scaling, and it is
possible that MythTV is indeed scaling prior to deinterlacing (that
would be bad) but a dev would probably be able to comment further.
Well. I tried mplayer, and I'm getting the same effect. The log is
attached.
The only thing remotely interesting might be this:

I'm not intentionally setting the output size different, they are set
to 0 for all the fields. The only thing that I do have set that could
be affecting anything is the overscan setting. I have both the horz
& vertical set to 4%. I disabled it, and there is no difference.

(Some do, like my old-tech Pioneer RPTV with quaint "CRT" technology.) I am using a dual-channel DVI cable from pacific cable. I am only running at a resolution of 1680x1050.

It really does look like that tho) Isn't the 1920x1080i signal pushing the limits of what DVI can handle? I presume you have a single-channel DVI. It almost looks to me like the set is on the hairy edge of sync with that signal. The 720p signals push slightly less information, which could explain why the ABC broadcasts work. I don't suppose the set has a VGA input for comparison? (Some do, like my old-tech Pioneer RPTV with quaint "CRT" technology.) __ Do You Yahoo!? Tired of spam? Yahoo!

The stripes are so wide because something (probably your video card) is scaling the pictures to a resolution less than 1080 lines high. Double-check you have deinterlacing enabled, and check the output from 'mythfrontend --verbose playback'. Also note that bob deinterlacing is disabled if you're playing at a speed other than 1x. -Doug signature.asc Description: OpenPGP digital signature ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] Playback vid corruption with 1080i (with pics)
I'm still seeing the problem that I reported a week or so ago. I took some pictures to show the effect. Hopefully someone knows something. Interestingly enough it is also causing the same effect on the OSD. Pics: http://www.jetcom.org/gallery/dragon-myth (There is some bluring due to difficulties in taking the picture, as I didn't have the tripod around. It really does look like that tho) I've tried different nvidia drivers (7664, 7167, 6629) no difference. I'm not sure what else to try. -original post--- I see wierd horizontal striping every 1/2 an inch or so. There is a jagged green area on the left (and covering parts of the picture). It sort of makes the picture shimmer. It's semi-watchable if you can ignore the effect (aka it doens't obstruct the picture). This only appears on my NBC broadcasts (and PBS too i think). I think this means it's on 1080i broadcasts. Fox & ABC are crystal clear. I don't get CBS right now. I believe that it also appears on upconvered material, ie the news was the same way last night. I only see it on one of my frontend which happens to have an amd64 using 64bit gentoo. So I'm assuming that it has something to do with that. I'm also assuming that it's related to the fact that he signal is interlaced. The recording itself is fine, ie I can play it upstairs on a different frontend. The machine is an AMD64 3500+, nvidia fx5300 connected DVI to a 2005FPW flat panel. I have also had this problem connected to a 50+ rp-lcd tv. I have tried various combinations of opengl vsync and various deints (kernel/bob). Not using xvmc (never got it to work on this machine), processor utilization is ~50-60% This *has* worked beautifully before. I don't know why/how it has changed. At one point I believed that it was mmx related, but now it seems to be independent. I have tried actively disabling mmx in the config. The only thing this now accomplishes is to increase my cpu util > 90-100%. I've seen this effect using various cvs builds on this machine since before 0.18 ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
