Bug #: 50618 Summary: Slow video playback with 40mbits mpeg2+vdpau Classification: Unclassified Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: nathanhirschauer@verfriemelt.org
Created attachment 62425 --> https://bugs.freedesktop.org/attachment.cgi?id=62425 mediainfo output of the video file
When playing an MPEG2-video with high bitrate (>40 MBps) on my Mobility Radeon HD 3450 (best graphics card EVER! :3) with VDPAU I get very low framerates when using hardware video decoding, cpu decoding is fine, here a quick comparison (no -benchmark results because mplayer did something weird there):
The mediainfo output of the video file is attached to the bug report.
CPU usages with different mplayer parameters:
mplayer without vdpau: MPlayer: 44,7%; Xorg: 12,8% -> Runs fine, 26fps
mplayer -vo vdpau: MPlayer: 43,4%, Xorg: 12,6% -> Runs also file, 26fps
mplayer -vo vdpau:fps=-1 -vc ffmpeg12vdpau: MPlayer: 14%, Xorg: 6,3% (**** Your system is too SLOW to play this! ****) -> Too slow! 1-10 fps
You may contact me via IRC (freenode, #radeon -> nathanhi) for the video file. I'm using mesa from git (git-775ba11), Xorg 1.12.1.902, xf86-video-ati git-c1b9b2c, libdrm git-481234f and Kernel 3.3.7.
