Info on the issue:
The UMG video works fine within the editor, and on PC. However, when packaged to mobile, the video no longer works, and results in a blank screen, only the sound plays without the visuals.
About video
The video format is .mp4 1920x1080 resolution. 25fps Size:1.6mb Data rate: 2375kb 6 seconds long.
Video is placed inside “Movies” folder.
Blueprints all working fine (as apparent from editor view / PC)
So in conclusion, the issue only resides when its on mobile Phone: Android - Oneplus5
If there’s anything else I can share to help the process of figuring out the issue easier, please inform me.
Will highly appreciate any input and help regarding this issue.
Hey, try to make sure to rule out codec issues first. Download Handbrake and re-compress the movie file with the android preset selected. Try to package that mp4 file with the project and see if it works. I’ve had issues myself with files that just playback black, and almost always it was a codec issue. Good luck.
Unfortunately, even after specifically using handbrake with android presets the same issue remains. I even ventured forth to render my own self-made video for android specifications yet no success.
Hmm that’s really strange. How about your settings in the android section in the project preferences… Are you using es2, es3.1… arm7, arm64? Since it’s playing back correctly in the editor, I think the best bet now is to see if there’s anything in the android build settings which could be wrong or malfunctioning?
Okay, I narrowed down the issue to being the Unreal Engine version.
In UE 4.15 it works. Its practically the same project settings and android settings.
I still cant tell what exactly is different on UE4.20, but for now im going to try migrating the project files into another empty project in 4.15 and hope for the best.
