How can i make the glowing effect behind a video?

Question

In the latest Youtube update, Google has put a glow effect behind the videos. He calls it "cinematicmode" which takes the video in question and creates that beam of light while the video is playing. I'm with a Boostrap5 project trying to replicate the same format that youtube has but I don't know how to do it. I don't know if it can be done with JS or with CSS or with some external library.

The code I am working on:

.container {
  max-width: 980px;
}

.title {
  color: white;
}
.bd-placeholder-img {
  font-size: 1.125rem;
  text-anchor: middle;
  -webkit-user-select: none;
  -moz-user-select: none;
  user-select: none;
}

.b-example-divider {
  height: 3rem;
  background-color: rgba(0, 0, 0, 0.1);
  border: solid rgba(0, 0, 0, 0.15);
  border-width: 1px 0;
  box-shadow: inset 0 0.5em 1.5em rgba(0, 0, 0, 0.1),
    inset 0 0.125em 0.5em rgba(0, 0, 0, 0.15);
}

.b-example-vr {
  flex-shrink: 0;

I tried to use backdrop-filter in CSS but does not fit with my description

Answer 1

I did something like this:

const VideoAmbilight = ({ videoSrc }) => {
  const videoRef = useRef(null);
  const canvasRef = useRef(null);
  let intervalId;

  useEffect(() => {
    const canvasElement = canvasRef.current;
    const context = canvasElement.getContext('2d');

    const videoElement = videoRef.current;

    function repaintAmbilight() {
      context.drawImage(
        videoElement,
        0,
        0,
        videoElement.videoWidth,
        videoElement.videoHeight
      );
    }

    function startAmbilightRepaint() {
      intervalId = window.setInterval(repaintAmbilight, 1000 / 30);
    }

    function stopAmbilightRepaint() {
      clearInterval(intervalId);
    }

    videoElement.addEventListener('play', startAmbilightRepaint);
    videoElement.addEventListener('pause', stopAmbilightRepaint);
    videoElement.addEventListener('ended', stopAmbilightRepaint);
    videoElement.addEventListener('seeked', repaintAmbilight);
    videoElement.addEventListener('loadeddata', repaintAmbilight);

    return () => {
      stopAmbilightRepaint();
      videoElement.removeEventListener('play', startAmbilightRepaint);
      videoElement.removeEventListener('pause', stopAmbilightRepaint);
      videoElement.removeEventListener('ended', stopAmbilightRepaint);
      videoElement.removeEventListener('seeked', repaintAmbilight);
      videoElement.removeEventListener('loadeddata', repaintAmbilight);
    };
  }, []);

  useEffect(() => {
    // Proxy the video request through Next.js server to avoid cross-origin issues
    const fetchVideo = async () => {
      try {
        const response = await axios.get(videoSrc, { responseType: 'blob' });
        const videoBlob = response.data;
        const videoUrl = URL.createObjectURL(videoBlob);
        if (videoRef.current) {
          videoRef.current.src = videoUrl;
        }
      } catch (error) {
        console.error('Failed to fetch video:', error);
      }
    };

    fetchVideo();

    return () => {
      // Revoke the video URL when component is unmounted
      if (videoRef.current && videoRef.current.src) {
        URL.revokeObjectURL(videoRef.current.src);
      }
    };
  }, [videoSrc]);

  return (

        </div>
