FLAC audio conversion yields empty tracks

Issue #249 resolved
Jon Stacey created an issue

Steps to reproduce

  1. Get or create an MKV input file that contains one or more audio tracks using the FLAC codec.
  2. Attempt to convert the MKV to M4V, or attempt to extract and convert one of the FLAC tracks to an M4A audio file.

Expected behavior

  1. Expect FLAC audio to be properly re-encoded to AAC Dolby Pro Logic II @ 160 kbps

Actual behavior

  1. Lots of CPU time wasted as the file is seemingly re-encoded. However, the output M4V or M4A file contains empty AAC tracks of 0:00:00.000 duration.

Surround Sound

My FLAC source is more than 2-channels and I have not tried a simple 2-channel FLAC file to determine if the bug is specific to this attribute.

    Works for me, please send me a small sample file I can use to reproduce the problem if you can.
