Stream sink such as evr can't be prerolled a second time, and when we are restarting from a paused state, those stream sink will already be prerolled so don't preroll them again. Otherwise we will be waiting for Prerolled events that will never come. --- dlls/mf/session.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

Current version tests one thing, leaves todo for EVR failing to restart, and then the fix is applied to the session logic, that does not have much to do with EVR.
Have you tried testing the session change by itself? EVR is complicated enough as it is, but for the NotifyPreroll() there is an easy way - you can use whole sample grabber sink, add prerolling interface to it, and see if it's called on Windows at all when transitioning from stop -> start.

I have tested this way because I have to make sure evr can't be prerolled twice. Because my other fix is to clear the `PREROLLED` flag in `OnClockPause`. It's only with these tests I can conclude that was not the correct fix.
that does not have much to do with EVR.
It does. Session is expecting EVR to preroll again after being paused. So the fix is either in EVR or in session. I needed these tests to rule out the fix in EVR.
testing the session change by itself?
I am not against adding a session Start -> Pause -> Start test, but that involves building a whole topology with sources, decorder and EVR, which has more moving parts. Don't know if you had a simpler test in mind.
I tested manually, without EVR, and yes, prerolling should not happen when restarting from paused state. Please drop the tests commit, leaving just the fix from 2/2.
This also helps mfplay test I have here that is now able to restart after pause, and it does use EVR.

Why do you think we need to drop the test commit, when you tested manually and confirmed it did uncover a real problem? I don't understand.

I also don't understand why you would have needed to test manually when you could just run my test case.

I already explained in https://gitlab.winehq.org/wine/wine/-/merge_requests/4545#note_54334. The test is for something EVR does, the fix is for something the session does. I wanted to see what happens with minimal sink, so complex components like EVR are not involved. We can still have EVR test for later, if it turns out it shows some additional problem.
The test is for something EVR does, the fix is for something the session does.
OK, if the problem is you don't want these in the same MR, I can open another one.
If you think the evr test is to complex, I am open to change it to use a minimal sink. But do we even know that all sinks behave the same way with regard to preroll after pausing? If not, then we do need to test every sink.
