UE 4.15 -- Media Player not working in editor

Noob question here.

I am trying out various stuff. I want to play video media in in my VR environment (Vive)
I am following the tutorial at Play a Video File | Unreal Engine Documentation. I got up to the step where I preview the player in the editor. When I double click on the player, it opens in the edit window, I can select a video (mp4), but it won’t play anything. The progress bar is stuck at 0:00. The video duration (6:04) shows up, but progress bar stays at 0:00/6:04. the file url looks right, I can toggle play/pause, but it never plays. Any ideas?

Edit: I tried some other videos, and some will play sometimes, but the editor just crashes for no good reason frequently when I play media. The media player seems to be very restrictive on what is in the mp4 container, even with a full set of codecs loaded on my system. All the Videos will play with windows media player 12, but very few work with UE 4.15 media framework. I thought media framework could use the codecs loaded on my system??

Even with the right format, the editor crashes a lot.

OK, just in case someone else is having problems too…

I changed to UE 4.14.3, and the media framework works without crashing the editor.
I guess media player is not ready for prime time in 4.15. Maybe the next bugfix…
I converted my mp4’s to wmv, and they play quite well in 4.14.3. I used MOVAVI transcoder to make wmv’s.

The media player is working fine in the editor for me but when I deploy on a Gear VR the media (connected to a texture) doesn’t play at all, it doesn’t play even the audio. With 4.14.3 it was working fine so I guess the media player is not working properly with 4.15.

Yes, thats what I thought. Exact same thing happens to me, but due to my scene there is no way that I can switch back to 4.14. I am hoping there might be an another solution for this in 4.15.

Hi there.

I have a little projects test with media player blue print setting. One video.mp4. When I compile it this test UE crash when the video is start. It is a issue from UE 4.15?

any idea about that?

thanks!
