Wrongly reported "video not supported"

I added support for the GStreamer errors messages to bubble up to mediaplayer-app now, so that's why you're getting this. It's curious why you're getting an error if playback is possible. I'd have to see on the media-hub-server side with GST_DEBUG=*:3 what other messages GStreamer is reporting and why it thinks it can't play these videos.

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".

Yes, the error reporting that is in place right now doesn't take into account whether the video, audio or text streams are supported by a decoder or not - it handles these in a generic sense. Additional code to make it smarter and more specific would be appropriate. The error messages in mediaplayer-app will need changing as well.
