[PATCH v8 0/7] MR5744: winegstreamer: Fix various Cinepak issues
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=56698 -- v8: quartz/tests: Test that avi_decompressor_source_qc_Notify does not deadlock if called from a foreign thread during IMemInput_Receive. quartz: Allow concurrent calls to AVI decoder qc_Notify and Receive. msvfw32/tests: Test that Cinepak rejects unsupported output types. iccvid: Reject unsupported output types. quartz/tests: Add Cinepak test to avi splitter. winegstreamer: Make AVI splitter use end of previous frame if the current frame doesn't have a timestamp. winegstreamer: Implement AM_MEDIA_TYPE to wg_format converter for Cinepak video. https://gitlab.winehq.org/wine/wine/-/merge_requests/5744

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=146276 Your paranoid android. === w864 (32 bit report) === quartz: systemclock.c:223: Test failed: Event should be signaled. systemclock.c:226: Test failed: Got hr 0.

Then let's switch commit 6 to the simplest possible implementation that satisfies the game, to minimize the amount of work to undo when implementing the correct fix. I don't think TryEnterCriticalSection() is the right solution, no. I wanted to figure out whether avidec is supposed to do any QC at all, or if v7 was the right solution, or if I could somehow find some way to prove something more interesting about native behaviour (which I unfortunately couldn't find a way to do).
I did some testing with native, and while our implementation isn't correct (in particular, native does not use ICDECOMPRESS_HURRYUP), it does look like native will drop samples when Late is high enough. So we do need to keep that logic, I think. I would advocate either: * revert to v7, with the separate lock, * just get rid of the lock and rely on TSO guaranteed by Windows. I don't have a preference. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5744#note_73659

I don't have a preference. That variable is 64bit, accesses are not atomic if compiled as 32bit. (And even if it was 32bit, data races are UB per the C spec; even if MS promises it's safe, I don't trust MinGW, Clang and TSan to make the same promises.)
A third option would be dropping the lock before calling IMemInput_Receive, but that's difficult with strmbase's current architecture. A fourth option would be to access that variable with Interlocked functions, but the most convenient write operation (InterlockedExchange64) doesn't exist in Wine's headers. Wouldn't be hard to add, but that's a little out of scope for this MR, isn't it? So I'd say using that extra lock is the best option here. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5744#note_73700
