Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Media Player not saving Media Texture after closing window


I've looked all over and I can't find anyone who has had the same issue with media files. I technically have a few issues, all related to the same thing, but the main issue is in bold below (Problem 1 c after the picture).

Problem 1.a. When I import video files into the Content > Movies folder, they appear as a File Media Source as expected, as long as I click and drag them directly into UE4. If I try to bring them in via File Explorer, they do not appear in UE4, however, other files, like JPGs will.

Problem 1.b When I click on the File Media Source, I am not able to see the video, but I can see that the File Media Source is linking to the file name. Not sure if this is an issue, but after watching countless tutorials, and looking into the UE4 docs, it seems like I should see the video play here. I have added a pic below to show what I mean.

Problem 1 c (The main problem): After bringing in the File Media Source, I create a Media Player, which I open. I then double click the media file in the section below the video, wait a few seconds, and then can see the video showing in the Output section next to Video Texture. That media texture will also show the video, and I can add it to a material and watch the Video display on any 3D mesh.

But, if I close out of the Media Player window, even after saving everything, the Media Texture goes black, and the Material goes black as well.

What I've tried: - AVI, MP4, MOV, WMV files. The results are always the same, no matter what file type, codec, etc. - Both PC and Mac computers

Here is a link to a video I uploaded showing the problem: https://www.youtube.com/watch?v=Ga9TZb5sBm0&feature=youtu.be.

Any advice would be greatly appreciated.

Thanks in advance.

I figured out the issue, at least for my problem.The Media Textures only display when the media player is open, BUT that is intended, because you have to add a simple blueprint.

What you need to do is this:

  1. After opening the Media Player and verifying that the Media texture is showing the video (while the media player is open), save the media texture

  2. Once done, create a blueprint following this guide from Unreal https://docs.unrealengine.com/latest/INT/Engine/MediaFramework/HowTo/FileMediaSource/ . [Skip to the blueprint section].

As it turns out, the Media texture will only play when the Media Player is open, but the blueprint accesses the Media player and plays the video when you preview the game.

How to edit a material with a media texture (since the blueprint works on play:

  1. Open the material with the media texture (or add it if you haven't)

  2. Open the Media Player (and select the correct video, and hit play). Also, check loop, so the video will keep looping.

You can now edit your material, as long as the Media Player window is open.
