When playing WMV3 streams using mplayer (or mplayer2 or ffplay or mpv) the output is corrupted: it looks like black rectangle with color mess at the top (https://imageshack.com/a/img22/534/yw2a.png). acceleration of h264 works fine, so I conclude that UVD is initialized succesfully Radeon Mobility HD 5850 Kernel 3.10.0, libdrm and mesa are from git master (30.06.2013) sample file: http://samples.mplayerhq.hu/asf-wmv/asf_with_chapters.wmv
Playback of WMV3 streams using UVD sometimes leads to computer hangs (see below). After upgrade of ffmpeg to version 2.0 from 1.2 these hangs happen much more often, almost every time I try to play a WMV3 stream after several seconds of playback. Gentoo was porting UVD patches to 3.9 kernel, and I remember that in the time of 3.9 kernel WMV3 deconding was producing correct images (and computer hangs also). With current ucode and kernel 3.9 WMV3 decondig produces the does not work also. Hangs seem to be almost complete: SysRQ does not work, mouse pointer does not move. The only thing that remains alive is laptop Fn key combsnations to turn on/off backlit of keyboard and screen backlight. Screen backlight turns on (after being turned off) by any key press. Screen picture disappears for 7-10 seconds every 20 or 30 seconds in the "hanged mode" and eventually lead to complete hang of the computer.
Created attachment 82368 [details] kernel log during a hang
Previous log was accured with Gentoo 3.9 kernel when I managed to kill player process before complete hang. Since neither keyboard nor ssh does not work after a short time after the hang, it is hard for me to get a log with kernel 3.10
Created attachment 82507 [details] kernel log after WMV3 decode attempt Today it managed to avoid hangs one time and gave me the log (the player was mpv master branch using ffmpeg 2.0). Instead of hanging, it dimed screen couple of times, then showed colours cycle (red, green,blue and so on) and than allowed me to kill the player from console. After killing the player, I returned to X. The desktop was there, but on the next screen repaint X crashed. After that I was not able to log in into KDE: kwin was crashing X on every start.
Since commit 5b4e2db12d9b45e898a8eb6599d928504ffd30c3 disabled VC-1 simple/main profiles for UVD 3, maybe it might have sense to disable it for UVD 2 also? VC-1 advanced profile seems to be working fine, without hangs.
My juniper with latest ubuntu 14.04(kernel 3.13) could not reproduce this bug please try new distros
neither ubuntu 12.04.4 can reproduce this bug seems it's solved by driver udpates
unfortunately (for this bug) I do not run JUNIPER card anymore. The very last time I checked this was in the beginning of may with Mesa master branch and the bug was still there.
Well that's actually not really a bug. The hardware just doesn't support WMV3, it only support VC-1 in the advanced profile. So depending on what stream you got it might work or not. Anyway I've just pushed a patch stopping advertising VC-1 simple and main profile (which are essentially WMV3) support on JUNIPER as well.
