I'm sorry, I don't understand. This is about games that have videos in a compressed format and expect the MF pipelines to be created in a specific way. Why should I even try switching these to uncompressed videos, when I debugged it and when it's very clear that they just inspect the pipeline and expect to find transforms in there? Anyway, I'm getting very tired of these pointless discussions. The questions are the same as before and whatever I do it doesn't seem likely to make any difference because we went through this already. There is one very simple reason we should do this, and it's because Windows behaves like this: it creates a pipeline with various transforms in it, and applications don't have to request anything for this to happen. This is now tested in length. Applications are broken because Wine doesn't implement Windows behavior: we tried to take a shortcut and it apparently doesn't work. Like everything else in Wine, we now need to implement Windows behavior more accurately to fix them, period. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5138#note_62502
