Sorry, I didn’t see the message.
I solved the problem differently.
Took the FFMPEG library and integrated it into UE.
Made the logic for decoding video into textures. Made Wawe Procedural for sound. And that’s it. Made a timer for playing sound, it also controls the display of frames. I take a texture, draw it into a material, and the material can then be in the UI and in a mesh on the scene.
