 Looks like removal of AV_CODEC_ID_AYUV (in 9ee59b63f5ea3 on 2024 March)
 has shifted all the following AVCodecID values to be 1 lower. There's a
 comment atop of enum saying "no value of an existing codec ID changes
 (that would break ABI)", so maybe literal removal is not a good approach.

 Found in blender when update of ffmpeg to 7.0 broke AV1 support
 (https://projects.blender.org/blender/blender/issues/140740), since parts
 of blender assume that AVCodecID values never change, but they did in 7.0.
 Now, maybe that is a wrong assumption on blender's part, but this change
 could affect other software too.
