quoije 5d3ccd65fe Re-anchor the A/V clock for each stream

The master clock was anchored once to the first stream's audio PTS, but
every stream starts its own PTS timeline (~90000). Subsequent streams were
paced against the stale anchor, so their targets were all in the past and
the video free-ran to catch up (the reported speed-up / poor fps). Reset
the clock anchor when each stream starts.
