[PATCH 0/1] MR7932: mf: Restart transforms and sinks on seek.

[Brendan McGrath (＠redmcg)]

This MR fixes seek in VRChat by copying the sequence of flushes/stop/starts that Windows does.

The order on Windows is:
1. Stop sources;
2. Flush MFTs;
3. Start sources;
4. Request output down the chain of sink inputs;
6. Flush sinks; and
7. Start the clock

This takes place whether we pause before we seek or seek without pause.
