This is an experimental and research codec of which ffmpeg is the only encoder and decoder, development has stalled since 2013 and these files don't exist in the wild. Deprecate the encoders to be removed next major bump, decoders to be removed one bump afterwards. We also disable the the encoders by default in configure, the decoders should be disabled by default next bump. Signed-off-by: J. Dekker <jdek@itanimul.li> --- Since this codec was added in 2004, there has only been one major non-maintenance, non-bugfix commit in 2013 (6026a5ad4f). That's 1 out of 107 total commits touching this file. This isn't a matter of the codec being unpopular like a niche game codec or some other codec with media found in the wild, it's an experiment which didn't continue and we continue to pay the maintenance cost. Deprecating the codec instead of immediate removal gives a grace period for anyone interested to pick up the format and make it the most advanced audio codec in FFmpeg if they so wish. It encourages an action to be taken whether that be improving the codec, or leaving it to be removed later. configure | 3 +++ libavcodec/version_major.h | 4 ++++ 2 files changed, 7 insertions(+)
