From: Anton Khirnov <an...@khirnov.net> The new API is more extensible and allows for custom layouts. More accurate information is exported, eg for decoders that do not set a channel layout, lavc will not make one up for them. Deprecate the old API working with just uint64_t bitmasks.

AV_CHAN_UNKWNOWN is fixed in the Amibsonic patch, but it should be fixed in this patch.

I still find the name av_channel_layout_valid() more readable, but feel free to keep it as is if you disagree.
