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.

Decoding: pts of the first frame of the stream, in stream time base.
Only set this if you are absolutely 100% sure that the value you set it to really is the pts of the first frame. This may be undefined (AV_NOPTS_VALUE).

This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented.
For fixed-fps content, time base should be 1/framerate and timestamp increments should be 1. decoding: set by libavformat encoding: set by libavformat in av_write_header
