Mythfrontend 0.22 VDPAU "Sparkle" / Error noise
|Reported by:||blammo@…||Owned by:||markk|
|Component:||MythTV - General||Version:||unknown|
<reposted from my thread on the MythUsers? list>
long time Myth user, did the 0.22 upgrade this weekend using ATRPMS repo.. everything went smoothly after a little google-foo for QT4.4 on Centos.. Backend (Centos54-64-bit) flawless upgrade, zero issues since. Frontend (Mythdora 10.21) little more pain, but got it upgraded as well.
Backend: Tyan S28xx series, 2xOpteron 285, 8G ram, 3ware 9500 w/lotsa drives, dual GIG-e to switch, 2xHDHR OTA Frontend: MSI AM2, 6400BE@3.2ghz, 9600GT, HDMI to Sony TV
I've been using VDPAU with mplayer SVN + NVIDIA 180 drivers for a few weeks, with zero issues. Picture is beautiful, smooth, crisp, and it's a little spooky to see 10% CPU with 1080p playback active.
However, VDPAU in myth has me less impressed today. Over the weekend watched probably 10+ hours of mixed HD playback, almost all recorded from ATSC-air from HDHR's. Almost all of it had what I can best describe as Horizontal fragments / bands / sparkles that would randomly appear, almost like noise throughout playback. They would stay on the screen less than 1 second each, but at times you could have lots of them on the screen.
If I go back into "playback profiles" and set back to CPU/CPU+/anything non VPDAU, same source, no noise. No change in the "deinterlace profiles" under VDPAU changes the behavior.
Other things I tried:
- 2 different video cards - 8500GT and 9600GT.
- 3 different driver revisions, 180, 185, and 190
- multiple different on-air sources, 480p, 720p, and 1080i
- liveTV seems to be worse than recorded, but not by much..
Again, non-VDPAU = no noise/artifacts
Playback of non-HDHR sources like H.264, VOB, etc,in mplayer produces ZERO artifacting.
It doesn't appear to affect stability, but it's downright irritating..and obviously a symptom of something broken.
the mythfrontend.log isn't giving up any help either, but perhaps I don't have debug high enough.. I'm getting some NVP: prebuffering, and WriteAudio?: buffer underrun, but only every couple minutes.. nothing to correlate to the constant artifacts.
I'm attaching both the xorg.conf and "-v playback" logs.
