I have tested with the .mp4 video that comes with the shootergame sample, under Content/Movies/LoadingScreen.mp4
If I import this .mp4 into my project as a media asset, I can hit play and it will play.
But if I make my own .mp4 files using PowerDirector12, those videos will not play when I import them.
So the repro is to make your own .mp4 video and try and import it as an asset into an unreal project.
Is there some conversion tool I can pass my .mp4 video through to make UE4 like it more?
I believe my .mp4 videos are indeed h.264 AVC codec, I know there’s a mention of this on the media framework documentation.
My question is not whether this is a known issue, my question is whether there is any conceivable solution since I currently have no way to produce video that the UE4 media framework will like
