I currently am having an issue where the first frame shows on a media element and then the media is unable to be played through .play(). I also have the issue where it will load an mp4 and only think it has audio or show a black screen. To replicate this issue, create a new windows vb form that targets .net 3.5 and is built towards x86. Add a wpf user control that has a media element on it and set the loaded behavior to manual. Add another window form that has a button and an elementhost. On the element host have the child be the wpf user control that was just made. On the button click call down to the usercontrol to set the source to an mp4 and call play. On the main form have a button which creates new versions of the form that you just made. Now to replicate the error click the main form button to make the new form and then click the play button. Repeat this and eventually you will get the media element to silently fail and either only think there’s audio or show a black screen that can’t be played.

Is this reproducible in the latest net framework or net core app? Could you please share a minimal repro if possible?
