I don't know when it got better. IIRC, it used to only play the first 2
channels. But either way, it would just make playback of multi-channel
ac3 and dca the same as that of multi-channel wav or flac or anything
else... and the user can still use -request_channels on the command line
to request in-decoder downmixing.
This is related to Anton's suggestion that it might be better to convert
the 3 uses of request_channels to private decoder options. It does
different things in each situation anyway.
AC-3: - uses downmix coeffs from bitstream
- does faster decoding by downmixing before IMDCT
DCA: - uses downmix coeffs from bitstream
MLP/TrueHD - skips decoding of some substreams
