Description Tommi Myöhänen 2006-12-04 14:36:45 UTC 
$ gst-typefind-0.10 squirrell.mpeg
squirrell.mpeg - audio/mpeg, mpegversion=(int)1, layer=(int)2

The problem is that typefinders for both video/mpeg1 and audio/mpeg return 99 probability and audio/mpeg is chosen, because it is alphabetically before video/mpeg1. One workaround to this would be to decrease audio/mpeg typefind rank from GST_RANK_PRIMARY to GST_RANK_SECONDARY, so video/mpeg1 would be tested and detected first.

patch to decrease audio/mpeg rank
Comment 2 Michael Smith 2006-12-04 14:45:00 UTC 
The mp3 typefinder has been drastically improved in cvs already, and now this is correctly detected as video/mpeg.

Dropping the rank isn't neccesary.
