[theora-dev] How to get the duration of a file or track?

[Ken Larson]

I'm starting with the theora player_example.c.  I want to be able to 
determine the duration of the audio/video ahead of time, to be able to 
display it somewhere.

I can't see anything obvious in ogg.h, theora.h, or vorbis.h for this.

Can anyone help me with the right place to look to do this?

Thanks,
