Setting up the Video Player
First of all, it's better to be used to the way videos are working and are being played in the Unreal Engine 4. So, although it's not required, we strongly advise you to read the following UE4 tutorial: https://docs.unrealengine.com/en-us/Engine/MediaFramework/HowTo/FileMediaSource
The next steps are describing how to use your own video file with our UMG Video Player.
Importing your video file
Drag and drop your video file into the Movies folder in the content browser, this will create a File Media Source asset.
In the Details window of the Video Player, set the "Media Source" parameter to the File Media Source created.
Setting up the media player
Create a new Media Player asset by clicking on the "Add New" button in the Content Browser. In "Create Advanced Asset", select "Media" then "Media Player".
Check "Video output MediaTexture" when prompted, it will create a Media Texture asset linked to this Media Player.
Set the "Media Player" parameter in the **Details** window of the Video Player to the **Media Player** asset created.
Setting up the materials
Create a new Material asset by clicking on the "Add New" button in the Content Browser. In "Create Basic Asset", select "Material".
Double-click on the Material created to open up the Material Blueprint Editor. In the Details window, in the "Material" panel, set the "Material Domain" parameter to "User Interface".
By right-clicking in the Graph window, add a new "TextureSampleParameter2D" node linked to the "Final Color" parameter.
Click on the node created. In the Details window, in the "Material Expression Texture Base" panel, set the "Texture" parameter to the Media Texture previously created and set the "Sampler Type" parameter to "External".
Create a new Material Instance asset by clicking on the "Add New" button in the Content Browser. In "Create Advanced Asset", select "Materials & Textures" then "Material Instance".
Double-click on the Material Instance created to open up the editor. In the Details window, in the "General" panel, set the "Parent" parameter to the Material asset previously created. This will show the "Parameter Groups" panel. In this panel check the "Video" parameter.
Set the "Media Material" parameter in the Details window of the Video Player to the Material Instance asset created.
Setting up the audio
Only if you want to play a separate audio file over the video file:
Drag and drop your sound file into the content browser, this will create a Sound Wave asset.
Set the "Sound Wave" parameter in the Details window of the Video Player to the Sound Wave asset created.
Note: If you are using the Video Player inside a widget, you will need to separate the audio from your video file into a wav file in order to play sounds.
