well, if its fixed fps, AVCodecContext.time_base should be 1/framerate and if 
its not fixed, well then theres no fps anyway (the old frame_rate wouldnt 
have helped you here either, as most likely it would have been 1/time_base)

there is also AVFormatContext.r_frame_rate which contains libavformats guess 
of the framerate
