[FFmpeg-devel] [PATCH] check if channel layout matches number of channels

[Justin Ruggles]

Hi,

Currently the output channel layout is always set to the input channel
layout, even when upmixing or downmixing.  This patch checks that the
channel layout matches the number of channels.  If it does not, the
output channel layout is set to 0.

I put the function in audioconvert.c/h so that encoders and decoders can
 also use it to validate the input.
