I've downloaded CVS 19-12-2004 version of mplayer, libvacodec and libavformat.
works very well with other formats, but when i try to run MP4 file (Nero
Digital) mplayer starts, plays about 1 second of movie (everything is OK, I've
got audio and video, even fullscreen is working) and crashes:

  • MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and won't help unless you provide this information when reporting a possible bug.


i tried to change vo (even vo null crashes mplayer after 1 second), disable
audio, set fps to 50 as it is in the file, etc. no luck.

i can't tell if example files from mplayer ftp are workin', cause both links 're

(In reply to comment #0)

mplayer: h264.c:2023: hl_motion: Assertion `((mb_type)&(0x0008|0x0010|0x0020|
0x0040))' failed.

That is the problem, it seems the file is not completely valid. The signal 6
below is because when this asserion fails abort() is called.
You can change the #undef NDEBUG in the libavcodec/h264.c to #define NDEBUG 1 to
disable all assertion checking and see what happens, but I doubt that it will
play correctly...

  • Resolution set to fixed
  • Status changed from new to closed

mplayer: h264.c:2023: hl_motion: Assertion `((mb_type)&(0x0008|0x0010|0x0020|
0x0040))' failed.

This means that the video used B-frames with B_DIRECT macroblocks. It's fixed in
CVS, though I can't guarantee that this was the only unimplemented feature used
in your video.
