[PATCH v2 0/5] MR2782: mf/tests: Test byte stream handler resolution time and media source presentation descriptor.

[Rémi Bernon (＠rbernon)]

This tests that the resolution should be quick enough to not trigger an Unreal Engine race condition. This also checks the determinism of the media source presentation descriptor stream ordering, as well as the stream selection updates when the media source is started.

[PATCH v2 1/5] mf/tests: Test byte stream handler to media source resolution time.

[Rémi Bernon]

From: Rémi Bernon

Unreal Engine has a race condition in its media player where it starts
the resolution of a media source, waiting for its completion in an async
task, and expects to set the media player source from its result.

At the same time, the media player uses timer to tick every 200ms or so,
and if the first tick happens before the media source resolution end,
the media player ends up in a corrupted state and playback may fail or
get stuck.

On Windows, the media source resolution takes very little time, and
usually less than 1ms. On Wine, because of the current design of the
media soruce, it can often take more than 200ms depending on the setup,
and very rarely less than 50ms.

[PATCH v2 3/5] mf/tests: Test media sources stream descriptors attributes.

[Rémi Bernon]

From: Rémi Bernon

The tests are all flaky because of the current media source design,
which uses high-level GStreamer abstractions, like decodebin, which
internally create threads and queues, and which cannot provide any
deterministic stream ordering.

I'm using the resolver now, seems to be working well enough with the repetition and it makes the code simpler.

I'm now repeating the resolution a couple of times. After running it several times it seems to be stable on Windows, where the minimum time will usually be ~0ms. I've kept a small tolerance of 2ms to be safe.

On Wine testbot, the minimum resolution time seems to be around 10ms-20ms.

I dropped these.

[Rémi Bernon (＠rbernon)]

Should I do something differently here?

[Nikolay Sivov (＠nsivov)]

I don't like the idea of testing timings, I don't think we have such performance tests anywhere else. Obviously making it faster is valuable, but testing how much time something took seems weird to me.

[Rémi Bernon (＠rbernon)]

Alright, what about the flaky tests? I can also postpone the tests until they are not flaky anymore.
