>                 Key: TIKA-4312
>                 URL: https://issues.apache.org/jira/browse/TIKA-4312
>             Project: Tika
>          Issue Type: Improvement
>          Components: tika-core
>            Reporter: Christian Schmidt
>            Priority: Minor
>
> 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 this:
>  * audio/mp4 → video/mp4 → video/quicktime → application/quicktime
