Subject [jira] Commented: (TIKA-590) Create facility for deeper introspection of media files
Date Sun, 30 Jan 2011 18:03:43 GMT

    [ https://issues.apache.org/jira/browse/TIKA-590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12988619#action_12988619

Andre-John Mas commented on TIKA-590:

Some cases I see:
 - hash
 - duration of song or movie
 - language tracks in movie 

I have looked into doing this with the mp3 file format, but in doing so I see it would require
a second pass over the inputstream and in certain cases would need to make use of other libraries.
For this reason I wondering whether an extension architecture would be needed? Imagine using
a native library on certain platforms such as libvlc.

> This feature would allow applications to dig deeper into files to define meta-data that
is not presented as a tag in the file. For example a file that has no duration information
could with a little more work provide this missing information. The idea is to let the API
user make a difference between data that is quick to retrieve and data that is slower to retrieve
because of the extra processing needed to get that information.
