Subject [jira] [Commented] (TIKA-852) Quicktime / MP4 Metadata Parser
Date Sat, 28 Jan 2012 21:18:10 GMT

    [ https://issues.apache.org/jira/browse/TIKA-852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195628#comment-13195628

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
