[PATCH v6 0/4] MR8034: winegstreamer: Call wg_format_get_max_size() to get the video decoder output sample size.
Windows uses a smaller alignment than gstreamer for some formats, for example NV12. This means we cannot use MFCalculateImageSize() to get the output sample size. Commit 7b79e3a87b1e switched to calling it instead of GetOutputStreamInfo() to fix some game bugs.
-- v6: winegstreamer: Call wg_format_get_max_size() to get the video decoder output sample size. winegstreamer: Do not pass a sample size to wg_transform_read_mf(). mf/tests: Add a video processor NV12 test with a width alignment of 2. mfplat/tests: Add NV12 650 x 850 to image_size_tests.

Windows uses a smaller alignment than GStreamer for some formats, for example NV12. This means we cannot use MFCalculateImageSize() to get the output sample size. Commit 7b79e3a87b1e switched to calling it instead of GetOutputStreamInfo() to fix some game bugs.

Rebased. Anything to do here? I have no information on the exact issue behind the change away from `GetOutputSizeInfo()`, so I'm not certain if taking the max of `MFCalculateImageSize()` and `GetOutputSizeInfo()` would be a regression.
I may be misunderstanding, but it doesn't look like we're solving the problem in the same way as Windows. Or, at least, you haven't confirmed that this patch is doing so.
Our current implementation returns aligned frames, whereas MFCalculateImageSize() returns an unaligned size. There are two possible fixes: either change our implementation to not use MFCalculateImageSize(), or change our implementation to return unaligned frames. It would surprise me if Windows returned aligned frames when MFCalculateImageSize() returns an unaligned size, and if so, the fix taken here would seem to be the wrong one.
Whether this is actually the case has not been confirmed, though.
Either way I feel like there probably should be some tests that are actually fixed in this series.

I'm not sure what you mean. The only sense in which this returns a size is the buffer size in the sample, whose alignment is a gstreamer requirement. We would need to modify gstreamer to change that.
I wasn't able to make an h264 frame which worked, so I have no test for it. I'll probably leave the tests added here and remove the implementation changes, because I don't know why `GetOutputSizeInfo()` is not used. It would solve the issue.

Yes, that's the size I mean.
whose alignment is a gstreamer requirement. We would need to modify gstreamer to change that.
Is that actually the case? GStreamer has a default alignment for any given format, but we can and do change that. That's the point of all that complicated alignment logic we have. Is some component rejecting alignment *below* the default?

Hmm, what happens when you try?
If you can't get one that works, can you at least try the one from whatever application triggers the bug, to confirm that this is the correct way to solve this?

See my comment higher up. Alignment in gstreamer is hard-coded to 4 for NV12, and when d3d-awareness is enabled, we allocate the sample buffer, which ends up being too small for gstreamer to use.
Hmm, what happens when you try?
I was getting wires crossed with some other testing I did a while ago. The issue is NV12 output from Theora, which we don't need to deal with in upstream Wine, and it also only occurs with d3d-aware output, which limits the scope. I tested d3d-aware h264 -> NV12 and there is no issue. It looks like upstream should be left as it is, at least for the moment.
