Summary of the bug:
In commit feccf2f6, AV_CODEC_ID_SNOW was moved in enum AVCodecID to be a
MKBETAG value. Values for subsequent IDs such as AV_CODEC_ID_TSCC
changed. This violates the rule:
"1. no value of a existing codec ID changes (that would break ABI)", and
impacts users of FFmpeg such as Chromium that have some dependency on this
rule.
How to reproduce:
