mplayer crashes opening wmv files encoded with DMO codec

[Stas Binko]

mplayer crashes with SIGSEGV opening some wmv files - I have pretty many such files, looks like the common part between all of them is they are encoded with "DMO video codecs". Here is mplayer output:

stas@stas-desktop:~$ mplayer mplayer-crash.wmv

The interesting thing here is that when I'm trying to play the same file running mplayer under gdb or strace - it does not crash, but opens files and plays them correctly (that's why cannot attach any stacktrace).
Video files are valid - e.g. they can be played by vlc.

Seems like one more common property of files causing crash - they all have ASF file format according to mplayer output (and DMO codec as mentioned before). One of such files is avi, not wmv.

[Doug McMahon (mc3man)]

The sample provided is a VC-1 wmv (or at least appears to be
By default mplayer will use dmo if available, some VC-1/wmv3 files can't be decoded properly, most others can though -
ffmpeg can decode VC-1/wmv3 and at this point does a better job on most if not all.

So if you went for example this it should play back fine
 mplayer -vc ffwmv3 /path/to/yourfile

(also note that ffwmv3vdpau will work on your sample - at least here
You can if desired set mplayer to use ffmpeg first with this in your .mplayer/config
vfm=ffmpeg

[Stas Binko (stas-binko)]

Thanks, seems like this workaround works for me (at least all files I've checked now - which is a pretty solid part of files available).

Hi, all!

Have the same problem. When w32codecs installed mplayer crashes like this:

But!!! The interesting thing is that I have the second ubuntu installed in VirtualBox with mplayer and w32codecs. I double checked all details (version, repository, dependencies) and can make conclusion that two systems are identical in video/codecs packages. But when I trying to play the same video in VBox Ubuntu it not crashes and playing well:

[kif0rt (kif0rt)]

I was figured out that problem by proprietary NVIDIA drivers used. After changing X driver to nouveau the problem was solved and mplayer opened wmv correct. I was tried the latest NVIDIA drivers from official website and problem still have the place to be.

[kif0rt (kif0rt)]

Workaround for proprietary NVIDIA drivers for X server:

change vo option in mplayer config to gl or gl2. And problem should be solved. So mplayer crashes only with next vo options:

vdpau
xv

[Gauvain Pocentek (gpocentek)]

Does this problem still happen on oneiric?

Thansk.

Cannot test on oneiric, but seems like did not reproduce on ubuntu 11.04, here is mplayer output for file attached here as crash cause sample:

I can confirm the issue still exists in oneiric. mplayer output for the video file attached here:

Old workaround with "vfm=ffmpeg" in .mplayer/config still works for me

Attaching file generated running "apport-cli -f -p mplayer --save 664848-oneiric.txt" - hopefully this could be useful
