Cast YouTube videos using Unity’s videoplayer

🌵 Needle Engine

Hello,

I’m working on my portfolio project, and I have a section where I pretend to cast videos of my projects. I’ve tried to do that, but when I use YouTube or Vimeo, it doesn’t work at all.
I’m having a CORS error in the web console (“No ‘Access-Control-Allow’ header”).

Is there any way to achieve that? Or do you know of any alternative?

Thank you!

Hello Albert Duran,

The CORS error you’re encountering indicates that the videos you’re trying to load are being blocked due to cross-origin restrictions. YouTube and Vimeo typically do not allow their videos to be loaded in an iframe or within a different origin environment (your project) unless specifically allowed.

Here are some alternative approaches:

  1. Direct Links to MP4 Files: If your project allows it, use direct links to MP4 files that are hosted on a server that allows CORS. This can be helpful since CORS headers can be set by servers to permit cross-origin requests.

  2. Use a Proxy Server: If you need to keep using YouTube or Vimeo, consider setting up a proxy server that retrieves the video content on the server-side, which could bypass CORS issues.

  3. M3U8 Streaming Format: For live streaming, you can use an M3U8 playlist format if supported. This format streams videos and can assist in bypassing some restrictions. Make sure your video player component can handle it.

  4. Embed Code: Use the embed code provided by YouTube or Vimeo, which usually generates an iframe that properly manages cross-origin requests. However, this may not suit your desired setup in Unity.

  5. Check Cross-Origin Headers: When you set up your video player, ensure you are specifying the crossOrigin attribute correctly in your VideoPlayer component. This is typically done by setting:

    this._videoElement?.setAttribute("crossorigin", "anonymous");

Here is a simplified example of how your VideoPlayer component could look:

import { VideoPlayer, VideoSource } from "@needle-tools/engine";

const videoPlayer = new VideoPlayer();
videoPlayer.url = "https://your-video-url.mp4"; // Direct MP4 link
videoPlayer.crossOrigin = "anonymous"; // Set CORS attribute

// Other player settings:
videoPlayer.playOnAwake = true; // Automatically play the video when the component is enabled

Make sure to test different approaches to see what works best for your specific needs in your portfolio project. If you have more specific requirements or error messages, please share them, and I can assist further!

Yes, but I’m still trying to figure out the best way to handle this situation. Right now I’m investigating the iFrame sample just in case it works for what I need.

Thank you!
