Trying to encode a mpeg ps file with mpeg2 and mp3 audio. Getting this on the console:

avenc_* not mpeg2enc, so -> gst-libav
Comment 2 Tim-Philipp Müller 2012-12-14 01:01:26 UTC 
$  gst-inspect-1.0 avenc_mpeg2video

Do you still have the file you tested with?

I wonder which element created that framerate, I think it should've snapped to 30000/1001 instead really.

In any case, transcoding should work fine now, if you add a videorate element before the encoder as well.
Comment 3 Christian Fredrik Kalager Schaller 2013-01-17 12:40:53 UTC 
Ok, not sure which file I used to test with here. So closing for now. As for adding a videorate element, this is encodebin so if another videorate element is needed then encodebin needs to add it.
