[FFmpeg-devel] My x86_64 running ffmpeg throws an FPE...

[Scott Doty]

Hi,

A recording with my MythTV causes ffmpeg to throw an FPE:

   ftp://upload.mplayerhq.hu:/MPlayer/incoming/2073_20070430001500.nuv

_[/w/Morel_Orel]_(scott at frenzy)_
$ ffmpeg -i 2073_20070430001500.nuv -vcodec mpeg2video -acodec copy testout.mpeg 2> errors
Floating point exception

The end of "errors" reads:

Marker bit missing before time_increment_resolution
[mpeg4 @ 0xaadc40]time_base.den==0
[mpeg4 @ 0xaadc40]header damaged
Error while decoding stream #0.0

The full output of "errors" can be found here:
