[PATCH v2 0/3] 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.
-- v2: mfplat/tests: Add NV12 650 x 850 to image_size_tests. mf/tests: Add a video processor NV12 test with a width alignment of 2.

Setting `output_plane_align = 1` has no effect on the issue. Calling `gst_video_info_align()` doesn't change the stride; it only sets the padding. The code line I mentioned above is the minimum stride we will get from `gst_video_info_from_caps()`, and I see no way to change the caps to deal with the issue either.
I added a video processor test in `mf/tests/transform.c`, but it's a draft at this point. The change in the first commit doesn't fix the failure in this test since the video processor is not fixed. Changing NV12 alignment to 3 in `mfplat/mediatype.c` `video_formats[]` fixes this, but that raises the question, should we fix this issue entirely in mfplat (including changing `MFCalculateImageSize()`) and handle any regressions from games making assumptions about alignment?

Thanks, the test looks good then I think we need to find a better way to fix this than reporting a value different from native from GetOutputStreamInfo.

I haven't found a way to test the video decoder code path which works in Windows as well as Wine. It can be done with a WMV frame by setting the transform D3D-aware, but Windows doesn't support this (and maybe we shouldn't either). The bug in Resident Evil Village will have to do for testing that. The video processor test is ok though.
