Nick Burch commented on TIKA-852:
---------------------------------

Initial parser added in r1237162. Currently, it largely just handles Apple M4A 
audio files. There are probably a couple more XMPDM keys we'd want to fully 
support these, and quite a few more we'd need before we could do video. (We'd 
also need some test files, and to decide how best to handle video files, see an 
earlier dev@tika discussion for details of the problems)

For now, the unit test is disabled, as it fails when asserts are turned on. I 
think this is a mp4parser bug though, so I've raised 
<http://code.google.com/p/mp4parser/issues/detail?id=30> for it

> From the investigations done for TIKA-851, it looks like a parser for the 
> Quicktime format, and MP4 (which is an extension to it) shouldn't be too hard 
> to do. This should be able to output some of the media metadata, such 
> duration, dimensions, and MP4 audio tags
> Information resources on the format are linked from TIKA-851
