MPlayer interrupted by signal 6 in module: decode video

• 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.

Random snow file

[cehoyos]

This should be fixed in the current version, thank you for the report.

[mplayer@…]

Indeed I can confirm that with the subversion checkout revision 34260, it works correctly with both your sample and my original file while my previous version crashed with both files.

Thank you

(In reply to comment #3)

This should be fixed in the current version, thank you for the report.

Out of curiosity, could you tell me which file(s) were changed or the revision number for the patch ?

Thank you

[cehoyos]

The fix was 4416931fc069332e267ab6df037a1227c051d7b1 in libavcodec/snow.c.
