[Theora-dev] Question about number of frames in ogg/theora video file.

[LS]

Hello.

How can I tell the number of frames in ogg/theora video file, without actually reading the file? Or, how can I tell 
its playing time (which is basically the same thing).

I didn't find the information in THEORA_STATE, THEORA_INFO, but with the codec installed (illuminable oggcodecs), 
Windows Media Player shows the ogg/theora file playing time, before it starts playing the file.

Thanks!
