-vo null has broken for audio files with embedded covers

[Artem S. Tashkinov]

I have several audio files with embedded JPG/PNG covers. When I'm trying to play them using -vo null MPlayer crashes:

% mplayer -vo null input.m4a

MPlayer interrupted by signal 11 in module: filter video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- 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.

MPlayer SVN-r36986-4.7.3

Patches should be submitted to the mplayer-dev-eng mailing list and not this bug tracker.

Sample file

Still broken in today's SVN snapshot:

Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()

MPlayer SVN-r37183

[compn]

i think the manual specifically says you need -vo null -vc null for it to work. and using -vc null works for me.

but i agree it shouldnt crash and is a bug.

[reimar]

Is this still reproducible? It does not crash for me with latest SVN.

[Artem S. Tashkinov]

Indeed fixed.
