Description    : A movie player for linux

Playing an h264 encoded .MKV 720p file that I've played countless times with various versions of mplayer, VLC, xine, Myth internal player, etc. I get this output trying to use the -vc ffh264vdpau:

Too many audio packets in the buffer: (4101 in 8255313 bytes).

Maybe you are playing a non-interleaved stream/file or the codec failed?

For AVI files, try to force non-interleaved mode with the -ni option.



FATAL: Could not initialize video filters (-vf) or video output (-vo).





Exiting... (End of file)

While that seems to be an audio error, I will repeat that I have played this file countless times with many versions of mplayer, VLC, xine, Myth internal player, etc. with no problems at all.

Thanks for any help :)

If you are using Packman's MPlayer version, you have to report problems at Packman.
Here (and on mplayer-users), only latest svn is supported.
(Remember to upload a sample in case the problem is still reproducible or use -demuxer lavf.)

Re: Mplayer+vdpau not playing h264

Try disabling any possible video filters first by adding -vf-clr to your command line switches.

Re: Mplayer+vdpau not playing h264

Thanks fellas, I actually completely removed the Mplayer from pacman (Arch's package manager). I grabbed the mplayer-svn (I'm at 29968-1) from our AUR (aka DIY) repo and built it with --enable-vdpau. The exact same command did not work, I actually got a tiny bit more helpful output:

Code:

Error while decoding frame!

[VD_FFMPEG] Trying pixfmt=0.

Unsupported PixelFormat -1

Could not find matching colorspace - retrying with -vf scale...

Opening video filter: [scale]

The selected video_out device is incompatible with this codec.

Try appending the scale filter to your filter list,

e.g. -vf spp,scale instead of -vf spp.

I simply took out the "-vf screenshot" option from the command voila, it's playing back with VDPAU perfectly!

Pretty incredible to watch a very high-bitrate, HD 720p video and see the CPU bar in conky not even blink :D I hope this helps anyone else :)

P.S. Just curious, how do I take screenshots/still images of the video now without -vf screenshot? I checked the man page, but it says to use the "s/S" key for taking a screenshot is with "-vf screenshot only," and I did just hit them during playback and output said "failed (forgot -vf screenshot?)". Thanks for any help :)

edit: Just to note, I had tried the command sans -vf screenshot with the Mplayer package from pacman, to no avail, so it's a version issue I'm guessing...

Re: Mplayer+vdpau not playing h264

Currently you can't take screenshots in MPlayer when using hardware decoding. The screenshot filter only works if the video has been decoded before the filter chain, which is not the case with hardware decoding.

I think support for screenshots with VDPAU would not be too hard to implement, and the one-frame delay after pressing 's' could be removed at the same time. However there are a lot of other features missing from MPlayer too so I'm not sure whether I'll actually try to implement this particular one.
