* Improve handling for start of nest cam stream
Add negative_cts_offsets to segment container options in order to better handle recording at the start of a stream. Nest streams start off with a negative offset, and if the segment container does not support it, then it adjusts the timestamps making it out of order with the next segment as described in issue #46968
* Update homeassistant/components/stream/__init__.py

* Simplify stream discontinuity logic
Separate the HLS stream view logic out of StreamOutput since the hls
stream view is about to get more complex to track discontinuities. This
makes the idle timeout, shutdown, and coupling between hls and record
more explicit.
* Remove stream_worker dependencies on Stream
Removee stream_worker dependencies on Stream and split out the logic
for writing segments to a stream buffer.
* Stop calling internal stream methods
* Update homeassistant/components/stream/worker.py

* Remove dependencies on keepalive from StremaOutput and stream_worker
Pull logic from StreamOutput and stream_worker into the Stream
class, unifying keepalive and idle timeout logic. This prepares
for future changes to preserve hls state across stream url changes.
* Unmark tests as flaky (though still flaky)
This put tests into the broken state where they are flaky and do not yet pass
* Fix bug in test_hls_stream with incorrect path
* Enable and de-flake HLS stream tests
Background: Tests encode a fake video them start a stream to be decoded. Test
assert on the decoded segments, however there is a race with the stream worker
which can finish decoding first, and end the stream which ereases all buffers.
Breadown of fixes:
- Fix the race conditions by adding synchronization points right before the
stream is finalized.
- Refactor StreamOutput.put so that a patch() can block the worker
thread. Previously, the put call would happen in the event loop which was
not safe to block. This is a bit of a hack, but it is the simplist possible
code change to add this synchronization and arguably provides slightly better
separation of responsibilities from the worker anyway.
- Fix bugs in the tests that make them not pass, likely due to changes
introduced while the tests were disabled
- Fix case where the HLS stream view recv() call returns None, indicating
the worker finished while the request was waiting.
The tests were previously failing anywhere from 2-5% of the time on a lightly
loaded machine doing 1k iterations. Now, have 0% flake rate. Tested with:
$ py.test --count=1000 tests/components/strema/test_hls.py
