The current SVN trunk of pyglet exposes a frame_rate property in VideoFormat, however this is not necessarily accurate, as it's merely what's reported by the file's metadata. I think in general using pyglet for video manipulation is a really bad idea -- the framework just isn't there, and what little video support is there is heavily geared toward realtime playback.
