Comment 2 for bug 1417950

The error is reported because not all streams in the container are supported. For BigBuckBunny_DivX_HD720p_ASP.divx, there are two audio streams of different types, ac3 and mp3, and I think the first one is not supported. For H263_56_AMRNB_6.3gp, the AMR audio track is not supported. For both cases, intalling more codecs removes the errors.

There is clearly a problem with the video with 2 audio tracks, as no error should be displayed when there is at least one stream available for video and another one for audio. For the second video I would say that the bug is displaying "Video format not supported" as it should be instead "Audio format not supported".
