AVCodecID

Identify the syntax and semantics of the bitstream. The principle is roughly: Two decoders with the same ID can decode the same streams. Two encoders with the same ID can encode compatible streams. There may be slight deviations from the principle due to implementation details.

If you add a codec ID to this list, add it so that 1. no value of an existing codec ID changes (that would break ABI), 2. it is as close as possible to similar codecs

After adding new codec IDs, do not forget to add an entry to the codec descriptor list and bump libavcodec minor version.
