claincly 42aecce353 Add a frame cache
Frame cache compensates for the fluctuation in frame processing times.

Imagine a frame takes 10ms to process, and the interval between two frames is
33ms. The third frame took 40ms to process.

If we don't have frame cache:
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms,
- Release frame 2 at t=33ms
- We start processing the third frame at t=33ms
- The third frame is due presentation at t=66ms
- But frame 3 is available at t=73ms, late

If we have a frame cache of say 3 frams,
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms
- Start processing frame 3, ready at t=50ms
- Release frame 2 at t=33ms
- Start frame 4, ready at t=60ms
- Frame 3 is due presentation at t=66ms
- Frame 3 isn't late
