[FFmpeg-devel] [PATCH] dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRA

[Anssi Hannula]

DTS-HD HRA streams do not always have an XBR extension in the extension
substream. Instead they can have only XXCh and X96 extensions in
there and still be considered DTS-HD HRA.

This is also confirmed with Onkyo TX-SR607 receiver which recognizes
such a stream as HiRes Audio.
