Posted the question (Xbox: no media player plug-ins are installed and enabled in this project - Cinematics & Media - Epic Developer Community Forums) but no response in almost a month so I’m trying again.
Can’t get video to play on xbox. Debugging the code shows that the SourceReader in MfMediaPlayer is always null. In FMfMediaPlayer::InitializePlayer(), there is an Async task that initializes Tracks which, as far as I can ascertain, is where SourceReader is supposed come from, however Tracks never actually gets set itself in that code. I manually forced it to set Tracks, which stops the null reference to SourceReader, and the VeryVerbose logs indicate that the video is actually playing, but nothing shows on screen.
Any help would be great.
