The pcm_bluray encoder has AVCodec.ch_layouts set, so that
ff_encode_preinit() checks that the channel layout in use
is equivalent to one of the layouts from AVCodec.ch_layouts.
Yet equivalent is not the same as identical; in particular,
custom layouts equivalent to native layouts are possible
(and necessary if one wants to use the name/opaque fields
with an ordinary channel layout), so one must not simply
use AVChannelLayout.u.mask. Use av_channel_layout_subset()
instead.
