[ubuntu] mplayer error AVC: nal size 0

[steveyeager]

I have a video clip from an Aiptek Action HD digital camcorder that plays back in MPlayer, but during playback it keeps displaying the error window Error! AVC: nal size 0. The clip is a MOV file with h.264 compression. It is not a perfect clip as it causes windows problems also, but it looks good and a previous distro I used played it wonderfully without the error.

Any thoughts?

You can try passing the -really-quiet switch to MPlayer, that should at least get rid of that window.

Excellent. That is exactly what I needed. I suppose I need to find out what is wrong with the video and fix it. But this is what I needed and why Ubuntu will always be one of the top distros available. Thanks so much.

how can i do that i don't undestand , i have the same problem.

[sken01]

can you answer me about this error? avc nal size 0

[shirilover]

The -really-quiet switch suppresses error dialogs.
It can be either added to a command line, like this

mplayer -really-quiet "video_file.ext"

or, it can be added to ~/.mplayer/config, like this

really-quiet=yes

As for the actual error, it seems to have something to do with h.264 video streams; but, I have been unable to find any explanatory data.

Hi

Thanks for the work around for the error messages. I'm worried that the error still occurs. When I launched mplayer from the command line:

gmplayer -really-quiet

and then ran a video (h.264 avc) I got the following output... can anyone decode the output? The video itself seems to play fine...

Thanks!

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.
