Hello,

until now I used the "Xv" video output driver in combination with ffmpeg's "ffh264" codec to replay H.264 encoded movies. For 1080p my cpu usage was reasonable high. (Between 70% and 90%.) Recently I found out, that for my hardware (NVIDIA GeForce 9600M GS, proprietary nvidia driver 195.36.24) the "vdpau" output driver in conjunction with the "ffh264vdpau" codec is the better option. So I enabled the "vdpau" use flag and re-emerged all packages, whose use flags had changed. But if I invoke mplayer with the command

Code:

mplayer -vo vdpau -vc ffh264vdpau


my cpu usage stays on the same high level as before, although the output says that XVMC-accelerated decoding is in use. My feeling is, that mplayer/ffmpeg still uses the "Xv" output driver with the non-accelerated "ffh264" codec as a fall back without telling me. Any ideas what I might have forgot?

Here some more information about my configuration:

Code:

$ sudo eselect opengl list
Available OpenGL implementations:
  [1]   nvidia *
  [2]   xorg-x11

$ sudo eselect xvmc list
Available XvMC implementations  ( * is current ):

One more piece of information: The X server process consumes most of the cpu power during play back. The X server process needs 50%-60%, the mplayer process needs around 20%.

try to add
Code:
vc=ffh264vdpau,ffmpeg12vdpau,ffvc1vdpau,ffwmv3vdpau,

in your ~/.mplayer/config file

(no need to add "-vo vdpau" mplayer option ... the -vc option is sufficient)

Thanks for the answer, but this should not change anything. Anyway I tried it as you never know, what might happen, but has no effect.

This line in the mplayer's config file only allows me to ommit the explicit "-vo ... -vc ..." on the comand line.

I that the line just allows the omission of explicit "-vo ... -vc ..." on the command line (even without the line -vo is not needed).

It was more to test with over codec : ffmpeg12vdpau ffvc1vdpau ffwmv3vdpau .. not just ffh264vdpau

What does mplayer display when you launch an h264 movie ?

OK, sorry for that misunderstanding. Here the ouput for an H.264 video:

Unfortunately I could not switch the language to English. MPlayer seems to ignore LC_ALL=C. But I hope you can guess, what each single line means. Most important in both cases you will find the lines

"XVMC-beschleunigtes MPEG-2" is "XVMC-accelerated MPEG-2". So everything looks fine, but my cpu usage hits the sky.

That message is bogus actually, XVMC is something completely different from VDPAU. A small but harmless bug in mplayer. Everything looks ok as far as I can tell, so whatever your problem is, mplayer's output doesn't show it. If no one here has a solution, you could try the nvnews.net forums. Nvidia folks post there regularly, including the VDPAU developer Stephen Warren.

What version of mplayer? If not latest, did you try it? If yes, did you try SVN?
