[Tutor] Video file metadata? (MP4/WMV)

[Ian Ozsvald]

Hi Allen.  I don't know of a Python module but I believe that ffmpeg will do what you want.  Inside ShowMeDo I start it using os.spawnv and I use Python to do some processing on ffmpeg's output.  We use it to transcode incoming AVI/MOVs to .FLV files.  This would be more involved than just using a module.

I've never looked at ffmpeg's handling of metadata but looking at the help I see:
ian at ian-desktop:~$ ffmpeg
...
-title string       set the title
-timestamp time     set the timestamp
-author string      set the author
-copyright string   set the copyright
-comment string     set the comment
-album string       set the album
...
which might be what you're after?

You should also be able to use ffmpeg for automated conversion to MP4.  The only drawback is that ffmpeg might not understand the most recent WMV formats (WMV9 if memory serves) as Microsoft won't open the spec.

HTH,
Ian.
