 The latest version of FFMPEG (N-40824-g31dfe20) is creating broken MP4
 files when starting with a TS file.
 The Audio is completely out of sync or creates no audio at all.

 This is a regression bug so I'm marking it important.

 This was working with FFMPEG build N-37915-g6cb2085 with no audio issues.

 Attaching the link to the input file (it is 40MB in size unfortunately to
 be able to replicate the issue).

 You can replace libvo_aacenc with ac3 and it still has the same problem.
 If I put -vn the audio comes back (but there's no video). Some reason the
 Audio/sync is broken after build N-37915-g6cb2085.
