[FFmpeg-devel] [PATCH] avformat/avienc: add muxer option "write_channel_mask"

Attached patch adds support for writing an empty channel-mask into AVI 

My use-case is handling recorded AVI files which have an 
unknown/empty/unsupported channel layout. Instead of writing the guessed 
channel layout into the output file, using "-write_channel_mask off" 
allows to write an empty channel mask instead.
