You can try this it works for me to start and stop the video and to switch between them.
The only hang up is that if i switch from one video to the other too fast.
It can stall up unless i wait to hit play i think i kinda bandaided it by loading it thru play then stopping it to initialize then new video but i dunno.
Not sure it really matters if you make the player static or not id rather not but im not to confident that things are working right underneath so i did it static to make it more strict to get a better grip on what was happening.
Instructions
Load videos thru the pipeline as normal.
Add a class file to your project and copy the below class into your project.
All this class is meant to do is to sort of baby the videoplayer the video player might recover this way from null textures and such when it can’t keep up ect.

In game1 i do this in update(…){ to control it.
if (Keyboard.GetState().IsKeyDown(Keys.OemPlus))
VideoController.LoadVideoPlayer(GraphicsDevice, Content, "thorClip");
if (Keyboard.GetState().IsKeyDown(Keys.OemMinus))
VideoController.LoadVideoPlayer(GraphicsDevice, Content, "TestRun");
if (Keyboard.GetState().IsKeyDown(Keys.P))
VideoController.PlayOrResumeVideo();
if (Keyboard.GetState().IsKeyDown(Keys.S))
VideoController.StopVideo();
if (Keyboard.GetState().IsKeyDown(Keys.A)) // doesn't work right never did.
VideoController.PauseVideo();
One more note all that get info and console stuff will make garbage its in there for testing you can remove it or comment it out its not needed.

vlc in monogame might eventually happen but that is on hold for now
Using ffmpeg scrpts to alter videos to make them small better or change format
Some stuff i went thru trying to get video to work on dx
Note there is no open gl video player at the moment.
