Nick Burch commented on TIKA-3007:
----------------------------------
There is currently no Parser for HEIC files, only mime detection. A basic
parser has been worked on by a community member, but is still pending a review
and merge
If you ask Tika to parse the file, it will get routed via the parent-type-known
rules to the MP4 parser, as there is no HEIC parser yet. That will set a basic
type as part of its attempts to handle it.
In general, the metadata-based endpoints only return sensible things for
formats with full parser support. You are hitting a case where there basic
support for a container format, but not for the specific child format
In almost all cases, if you want to know what a file's type is, call detect.
(The only one that springs to mind where metadata-based may be better for
detection is password-protected formats where you know the password)
> Heic images are detected as "application/mp4" when using tika as server

> Key: TIKA-3007
> URL: https://issues.apache.org/jira/browse/TIKA-3007
> Project: Tika
> Issue Type: Bug
> Components: server
> Affects Versions: 1.23
> Reporter: Johan
> Priority: Blocker
>
> Related to https://issues.apache.org/jira/browse/TIKA-2942
> It seems the detection of the heic imags is working for the standalone jar
> (tika-app-1.23) but not for the server component (tika-server-1.23).
> tika-app-1.23.jar from [https://archive.apache.org/dist/tika/] detects the
> image with image/heic but it does not work for the server component
> tika-server-1.23.jar that one returns still "application/mp4". Any clue what
> might be going wrong? Code has been added only to the tika jar client and not
> to the server?
