Comment (by heleppkes):

 Atmos in EAC3 is a joke anyway. Its still a fixed bitrate stream, so the
 Atmos data actually eats space away from the main audio stream - which is
 also why the size doesnt change when you transcode it like that, your new
 stream actually has a higher bitrate for the base audio then the source.

 Maybe it is outside of stream... See for yourself - they can not store
 ATMOS in single bit.

 Mediainfo reports Atmos data. And i really doubt Dolby would offer a test
 sample for the feature without an actual relevant stream.

Comment (by llogan):

 To elaborate, we as an organization don't generally plan milestones.
 Things just happen when they do. I don't know if there are plans to work
 on this because I can't speak for others. The only set release plans are a
 loose schedule of release dates. Progress depends on contributions from
 interested individuals, and anyone is welcome and encouraged to do so.

 The best way to get something included into FFmpeg is to participate in
 development. You can submit patches, fix bugs, review patches, etc. You
 can also post a bounty or offer to sponsor development.

 More importantly, put it into a container like mp4, don't use raw aac if

Comment (by Grabien):

 In this last example:
 {{{
 ffmpeg -i MP4WithAACAudio.mp4 -c:a aac -b:a 64k output.aac
 }}}
 I specify constant bitrate and don't use -vbr flag. I assume that FFMPEG
 should create CBR file in this case with 64 kb/s bitrate. But bitrate of
 output file is 4 kb/s.

Comment (by heleppkes):

 If you want accurate duration and bitrate information, then store it in
 mp4/m4a, not raw .aac - or encode as CBR.

 Raw aac files don't have any way to store duration or bitrate, and if you
 encode it as Variable-Bitrate (VBR), there is no good way to accurately
 determine this information, and all it can do is  guess.

Comment:

 Yes, output file can be played, but it is incorrect:
 - bitrate of output file is 4 kb/s, bitrate of original file is 45 kb/s;
 - duration of output file is 2:58.960, bitrate of original file is
 0:15.050;
 - timing in output file is not corresponds to timing of original file.

 Even when I try to specify codec and bitrate:

 {{{
 ffmpeg -i MP4WithAACAudio.mp4 -c:a aac -b:a 64k output.aac
 }}}

 FFMPEG always creates file with 4 kb/s bitrate:

 {{{
 Stream #0:0: Audio: aac (LC), 44100 Hz, stereo, fltp, 4 kb/s
 }}}
