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.
This often, but not always is the inverse of the frame rate or field rate
for video.
- encoding: MUST be set by user.
- decoding: the use of this field for decoding is deprecated.
Use framerate instead.
