extracting audio/video MetaData from media files

[Wayne Earnshaw]

Hello,

I was wondering what tools might be recommended for extracting metadata within a Red Hat environment. I have a variety of formats to extract Metadata from (it's a Java app, but I'll probably need to call out to a command-line tool like http://mediainfo.sourceforge.net/en to extract this information since Java doesn't handle this). 

If there is a native Red Hat tool that would be preferred for support/maintenance/$ reasons.

video formats:
* Flash
	o On2 VP6
	o Sorenson Spark
	o AVC (H.264)
* WMV
	o VC-1
	o WMV7, WMV8, WMV9
* MPEG1
* MPEG2
* MPEG4 
	o AVC (H.264)

audio formats:
* MP3
* AAC (H.264)

Cheers,
