--------------------------------------
c960657 opened a new pull request, #1960:
URL: https://github.com/apache/tika/pull/1960
https://issues.apache.org/jira/browse/TIKA-4312
tika-mimetypes.xml currently defines these two <sub-class-of> ancestor
chains:
- audio/mp4 → application/quicktime.
- video/mp4 → video/quicktime → application/quicktime.
Based on [RFC 4337, section
2](https://datatracker.ietf.org/doc/html/rfc4337#section-2), it is my
understanding that audio/mp4 is a special case of video/mp4. I thus suggest
changing the ancestor chain of audio/mp4 to
- audio/mp4 → video/mp4 → video/quicktime → application/quicktime
> Make audio/mp4 a subclass of video/mp4
