E.g. chromaprint expects to be fed 16bit signed PCM in native endianness, yet there was no check for this. Similarly for other muxers. Use the new FF_OFMT_FLAG_ONLY_DEFAULT_CODECS to enfore this where appropriate, e.g. for pcm/raw muxers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
