UMG video don't work on device

Hey i’m having trouble playing a intro video on my device (IOS) it won’t play or show up, i try different format, different sizes but noting any suggestion ?

Hello ,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. What version of the engine are you using?
  2. Can you reproduce this issue in a clean project?
  3. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  4. Could you provide screen shots of any blueprints/widgets that may be involved in this issue?

I’m using 4.10, i also tried using 4.11 clean project on both but no luck.

Thank you for the additional information. However, I am a little unclear as to what you meant when you said “no luck”. I have a few more questions for you.

Additional questions:

  1. Did you mean that you were not able to reproduce this issue in a clean project or that the video did not play in a clean project?
  2. What device exactly are you using?
  3. What is the current OS that is being run on the device?
  4. If you cannot reproduce this issue in a clean project, could you provide the project that is experiencing this issue?
  5. If you provide a project, could you provide the steps needed to reproduce this issue in that project?

No luck as of don’t work, i’m testing on two iphone 6 running on 9.3 and the other one 9.2.1 i also try adding the video mat to a box (BSP) but when packaging and testing it on the device it appear with a different texture not the video mat…weird, look like a bug or i’m just doing something wrong.

can you give me your private email so i can send you my project ?

Apparently i was using the wrong video format, the only video format that i can play in unreal is WMV however when i imported a MP4 video in unreal it doesn’t play it only give me a black screen but when a package my game for my iphone the video work i guess this is a bug.

Hello ,

With the new information that you have gathered, are you able to reproduce this issue in a clean project? If so, could you provide a detailed set of steps to reproduce this issue on our end?

Hey sorry for the late reply i upgrade my engine to 4.12 but i still have the issue i tried a different video, same format (MP4) but doesn’t play in the editor, i uploaded the video through explorer and through the engine itself but don’t work, WMV is the only video format i can play in unreal.

I now package my game and now not even mp4 video won’t play, i got everything setup just like your document but nothing work ?


I have a couple of links to documentation I would like you to look over. Both of those should get you going in the right direction. Make sure to place your media asset file within the Content/Movies folder for it to play correctly in a packaged project. I hope that this information helps.

Make it a great day
