I found the trigger for the output type change. The H.264 decoder returns `MF_E_TRANSFORM_STREAM_CHANGE` to change the format, presumably because the aligned size has become known. GStreamer does this too, so our decoder transform is already compliant. Wine's media source currently decodes the stream, so there is no transform to trigger this change in the session engine, hence the test failure there. After that is fixed, the only remaining issue will be to pass the format change down to the sink.
I added a transform test.

We could use MEStreamFormatChanged to report format change at the source.

Wine media source shouldn't decode in the first place, upstream still uses GStreamer-based media source by default but the winedmo based one does the right thing. https://gitlab.winehq.org/wine/wine/-/merge_requests/5988 could perhaps be merged to make them both behave similarly.
I think upstream MF pipelines should be good enough for it to work by default, but we need to be careful and we should probably make sure to upstream any remaining relevant Proton patch before doing so.
