[PATCH v5 0/3] MR607: mf: Fix session command handling and SESSION_CMD_END.
-- v5: mf: Remove command from the command list on execution. mf: Delay media session command processing when presentation is ending. mf: Use a dedicated interface for sample allocator ready callbacks. https://gitlab.winehq.org/wine/wine/-/merge_requests/607

Last commit is not strictly necessary, it was meant to cleanup a bit the logic but it has some issues, I'll try to fix it. Nevertheless I think something like that could fix the issue, event though I'm not completely satisfied with delaying commands like that. I couldn't think of a better way though. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/607#note_7523
