Hi,
I am trying to call a UMG widget that has a material with a Media Player. The Media Player has a list of Image Sources (PNG sequence with alpha). To change the media player, I use an “Open URL” node. But looking at the absolute path - it will certainly not work and does not work when packaged. I read about how to copy your movie files into the Content/Movies folder and importing it to create a Media Texture Asset. While that may work for an mp4s, PNG sequences do not seem to do the same thing. Importing PNG sequences does not create a Media Texture Asset. Also when importing the PNGs - the animation in Media Player Asset runs slower then others that did not import PNGs… why is this happening? All 6 of my Image Sources are manually set to 60fps but the one’s that have been imported have super slow in playback in both the Media Player and while running in Editor - I also get “Failed to Load image…” and “Unsupported file format” errors in the Output Log.
Then, you’re supposed to reset the URL and re-assigning it to make a relative path but doing this is not required. It already is relative…sort of. When editing the Image Source it shows the URL w a relative path “./Movies/Example”
But…back to the widget. the Open URL node still requires an absolute path to work in editor. I tried changing the Open URL node to “/Content/Movies/Example”, “/Movies/Example”, and “Projectname/Content/Movies/Example” and nothing works (packaged or in editor).
I get this error in the Logs: "“MediaAssets: Error: Failed to validate URL”
If I leave the URLs absolute and then package - I get the following errors in the logs: “The directory …/…/…/…/…/…/Projects/
Company/UE4/ProjectName/Content/Movies/Example does not contain any image files”
The folder does contain image files… and even if it did, this packaged game will not work on any other computer.
How do I set relative paths for the Open URL node for Image Sources?
I am unable to figure out what to put in the Open URL node… if that even is the issue. Any insight would be much appreciated.
