[FFmpeg-devel] [PATCH] Fix #1827: segfault with DCA multichannel downmix

[Nick Brereton]

This patch fixes this problem:

https://ffmpeg.org/trac/ffmpeg/ticket/1827

When -request_channels is set to 2 to downmix a multichannel DTS track 
which uses the XXCH extension a segfault occurs, this was because the 
embedded downmix was being processed even if the XXCH extension was not 
decoded.
