get video metadata information

Any tool in ruby or Command line interface to get all the metadata associated with a video file.

I need to store the metadata in the table for indexing purposes.

I tried using ffmpeg and but the metadata 开发者_开发问答is not formatted.

ffmpeg -i normally gets the job done, however, there's a Ruby tool that manipulates metadata; It will even output the data as xml, which can be useful
