Timebase is the inverse of FPS.
* this is the fundamental unit of time (in seconds) in terms
* of which frame timestamps are represented. for fixed-fps content,
* timebase should be 1/framerate and timestamp increments should be
* identically 1.
* - encoding: MUST be set by user
* - decoding: set by lavc.
