Tracing back the ffmpeg_vers variable, the error is in export/ffmpeg.pm
on line 75.  The regex for checking the ffmpeg version currently reads:
    m/ffmpeg\sversion\s0.5-/si

Since your version does not have a trailing hyphen, it's not matching.
If you change this to:
    m/ffmpeg\sversion\s0.5[,-]/si
then it should work (I've put the [,-] in there to make sure it'll only
match the exact 0.5 version - I'm not sure how critical this is though).

Cheers,
    Robin
