Real base framerate of the stream.
This is the lowest framerate with which all timestamps can be
represented accurately (it is the least common multiple of all
framerates in the stream). Note, this value is just a guess!
For example, if the time base is 1/90000 and all frames have either
approximately 3600 or 1800 timer ticks, then r_frame_rate will be 50/1.
Code outside avformat should access this field using:
av_stream_get/set_r_frame_rate(stream)
