[FFmpeg-devel] [PATCH] ffplay multi-channel fix

[Justin Ruggles]

Hi,

Here is a patch to fix ffplay for decoders which support multi-channel,
but do not support downmixing.  Basically it moves the SDL audio init to
after decoder init, which allows for AVCodecContext.channels to be
changed based on AFCodecContext.request_channels.  If the requested
channels are not granted, then SDL needs to be init'ed with the full
number of coded channels.  The result is that multi-channel wav, vorbis,
flac, etc... will play, but the first 2 channels are treated as
left/right.  All channels are displayed in the oscilloscope.
