 Summary of the bug:

 The commit referenced below breaks capturing valid AAC streams without
 reencoding them. The change from WARNING to ERROR makes it impossible to
 capture streams that were captured OK earlier.

 https://github.com/FFmpeg/FFmpeg/commit/51da7d02748cc54b7d009115e76efa940b99a8ef

 This is the earlier version:

 This is the new version with the commit:
 http://i58.tinypic.com/3451nok.png

 How to reproduce:

 Fails:

 {{{
 ffmpeg -i
 http://nordond6c-f.akamaihd.net/i/wo/open/90/90e13dea4c96346aa7874839eb9b66dc1101d689/90e13dea4c96346aa7874839eb9b66dc1101d689_,141,316,563,1266,2250,.mp4.csmil/index_4_av.m3u8
 -map 0:v -map 0:a -c copy test.mkv
 }}}

 Works (with libvorbis encoding of AAC):

 {{{
 ffmpeg -i
 http://nordond6c-f.akamaihd.net/i/wo/open/90/90e13dea4c96346aa7874839eb9b66dc1101d689/90e13dea4c96346aa7874839eb9b66dc1101d689_,141,316,563,1266,2250,.mp4.csmil/index_4_av.m3u8
 -map 0:v -map 0:a -c:v copy test.mkv
 }}}
