Video init with createObjectURL is not working anymore

[s00500]

The camera needs to be initialized with:

    console.log("chroma-key: start video", stream);

    // init video object
    this.videoStream = stream;
    this.video = document.createElement("video");
    this.video.autoplay = true;
    this.video.srcObject = stream;
