1681	Bad output framerate decision	jwjwjw		"Summary of the bug:

The attached sample file does not play properly once encoded in ffmpeg using the latest git-master. The video either freezes while the audio plays or the video is too jerky. During the encode the following appears:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x65e240] multiple edit list entries, a/v desync might occur, patch welcome

Despite this though, the file does encode and play fine (including the above message during the encode process) using earlier version N-31890-gecaf514 so I reasonably conclude that it is a regression bug.

How to reproduce:
