[FFmpeg-devel] [PATCH 2/7] swresample/matrix: switch internal clean_layout function to not drop high bits

[Jan Ekström]

These bits are utilized by channel layouts such as 22.2. If those
are dropped, the returned channel layout is no longer a match
against the AV_CH_LAYOUT define when returned from this function.
