 On 0.27.4, when doing an HLS transcode of a HD (MCH audio) recording, the
 end result is all of the video is in the final segment file, and there is
 no audio track.

 I hear that master doesn't have this problem.

 ---

 This is a compound problem. The last good commit is 3.152.926bb8d. The
 next commit 3.153.db74cee creates normal segment files, but has garbled
 audio. That is the first problem.

 After that, 3.154.07d4b2c puts all the video in the final av segment file
 and no audio tracks are written anywhere.
 I watched the files being written, only html/m3u8 get data until it gets
 to the final av and seems to write it all out of a buffer.

 I noticed the 3.152.mi has "Mode extension: MS Stereo" and 3.153.mi does
 not.
