Comment:
The caf specification says that Apple Lossless in caf {{{has no format
flags.}}}
Apple's own (muxing and demuxing) implementation is apparently different
but since this requires some (minor) effort and the resulting files could
theoretically be rejected by overcautious demuxers and would not fix any
existing demuxers, I suggest not to change current FFmpeg behaviour.
Please reopen if the specification I read is outdated (was changed) or I
misunderstood or if there is software that requires the format flags for
alac.
