Video renderers assume that the player position is advancing linearly while in
the started state. MediaCodecVideoRenderer schedules frames for rendering in the
future in the expectation that the player position is advancing.

This assumption is not currently true when using a position from the AudioTrack:
the player position can be fixed for (in the worst case) up to about 100 ms
before it starts increasing. This leads to an effect where the first frame is
rendered then a few other frames are rendered, then there's a pause before
frames start being rendered smoothly.

Work around this issue by checking whether the position has started advancing
before scheduling frames to be rendered in the future.

It might be preferable to make the audio renderer only become ready when its
timestamp can start advancing, but this is likely to be complicated.

Issue: #3841
