Peter Kronenberg created TIKA-3310:
--------------------------------------
Summary: MP4 video detected as application/mp4
Key: TIKA-3310
URL: https://issues.apache.org/jira/browse/TIKA-3310
Project: Tika
Issue Type: Improvement
Reporter: Peter Kronenberg
Attachments: sample-movie.mp4
The attached file is an MP4 video. When running _new Tika().detect()_ it
returns _video/quicktime_. But when actually running it through the
MP4Parser, it returns a very generic _application/mp4_.
Looking at the code, it seems that the generic type comes about because the
_majorBrand_ of my file is _isom_, which doesn’t match any of the desired
values, so it defaults to _application/mp4._ Now, I know absolutely nothing
about mp4 encoding. But looking further, I see there’s a list of
compatibleBrands, which in my case, includes _mp41_, which would match the
expected type of _video/mp4_ .
I coded this up so that if the major brand does not match one of the desired
values, it checks to see if any of the compatible brands match, and uses the
first one it finds.
Is this a proper solution?
