[FFmpeg-devel] 5.1 AAC on 0.5 branch

[Pascal Patry]

I've been testing a lot of content on the 0.5 branch for regressions directly in FFplay. I 
found that AAC audio using multiple channels don't work properly.

FFplay correctly sets 'request_channels' to 2, but it seems to still get 5 channels from 
these streams.

An example of that kind of content can be found here:
http://movies.apple.com/movies/universal/the_incredible_hulk/the_incredible_hulk-tlr2_h1080p.mov

Audio stream:
Stream #0.1(eng): Audio: aac, 48000 Hz, 5.1, s16

Stereo AAC streams are working perfectly. This is most likely a regression because an 
older version of the AAC decoder is able to downmix this video to 2 channels.

Is there any chance of getting that fixed for the release?

Thank you,
