Since r22355, it is possible to mux AAC into transport stream (and play back the
resulting file with sound).

[issue1674] AAC not working in mpegts

[Carl Eugen Hoyos]

Carl Eugen Hoyos  added the comment:

I think muxing AAC in mpegts is just unsupported, but since ffmpeg does not warn
about it (at least not specifically), there is a bug.

[issue1674] AAC not working in mpegts

[aviad rozenhek]

New submission from aviad rozenhek :

I am trying to mux AAC [2 channel, 44.1khz] into mpeg-ts stream.
it does not work for me, when I use ffmpeg to decode the file, ffmpeg 
misdetects the number of channels and sampling rate of audio.
when using ffplay, the video plays without audio.
