## state changes
A sink always returns ASYNC from the state change to PAUSED, this
includes a state change from READY→PAUSED and PLAYING→PAUSED. The reason
A sink always returns `ASYNC` from the state change to `PAUSED`, this
includes a state change from `READY→PAUSED` and `PLAYING→PAUSED`. The reason
for this is that this way we can detect when the first buffer or event
arrives in the sink when the state change completes.
A sink should block on the first EOS event or buffer received in the
READY→PAUSED state before commiting the state to PAUSED.
A sink should block on the first `EOS` event or buffer received in the
`READY→PAUSED` state before commiting the state to `PAUSED`.
FLUSHING events have to be handled out of sync with the buffer flow and
`FLUSHING` events have to be handled out of sync with the buffer flow and
take no part in the preroll procedure.
Events other than EOS do not complete the preroll stage.
Events other than `EOS` do not complete the preroll stage.
## sink overview
- TODO: `PREROLL_LOCK` can be removed and we can safely use the `STREAM_LOCK`.

```c
# Commit the state. We return TRUE if we can continue
# streaming, FALSE in the case we go to a READY or NULL state.
# if we go to PLAYING, we don't need to block on preroll.
