 When muxing an avi (video only) and lc aac with ffmpeg:

 1) cbSize is set to zero in the WAVEFORMATEX structure.
 2) AudioSpecificConfig is missing.

 avi: http://www.datafilehost.com/d/abf5b1ae
 aac: http://www.datafilehost.com/d/6ca94fe8

 ffmpeg -i h264.avi -i SurroundTest20.aac -c copy SurroundTest20.avi

 Since wFormatTag = WAVE_FORMAT_RAW_AAC1, cbSize should be two (and five
 for SBR?) and AudioSpecificConfig should be filled (with cbSize its size):

 http://msdn.microsoft.com/en-
 us/library/windows/desktop/dd317599%28v=vs.85%29.aspx

 Here is the resulting file:
 http://www.datafilehost.com/d/a7f35def

 At the address 0x1168 the WAVEFORMATEX structure starts. I expect
 something like

 FF 0002 0044 AC00 0094 3E00 0000 0610 0002 0012 10 ...

 instead of

 FF 0002 0044 AC00 0094 3E00 0000 0610 0000 004A 55 ...
