JSMpeg not able to get stream from RTSP

i'm trying to get a RTSP stream inside a webpage, but with no success actually.

For this I followed exactly the tutorial of JSMpeg : https://github.com/phoboslab/jsmpeg

With a custom FFMPEG command : 

ffmpeg -i "rtsp://myurl/media.smp" \
 -vcodec h264 -f mpegts -codec:v mpeg1video -s 1290x980 -b:v 8000k \
 -r 25 -max_muxing_queue_size 9999 http://localhost:8081/supersecret

My websocket well receive my connection on it.

But my canvas is still a white square : enter image description here

The weird thing is when I change the websocket url with a false one, in my code, the canvas turn to black.

So I guess that it turn WHITE when it receive something.

Thansk for help

Most likely you'll have fixed this already, just leaving these here for others that come across the same issue.

In my case i was forgetting the call to start() on the newly create stream object.

The function below is part of an object I created to keep track of the streams in instantiate, useful for multiclient multistream situation.

createStream: async function (rtspURL) {
        const myPort=9999
        console.log(`Assigning port ${myPort} to new stream` );
        try {
            this.streams[rtspURL] = new Stream({
                name: 'stream:'+rtspURL,
                url: rtspURL,
                wsPort: myPort
            });
            console.log("New stream instance created");
            console.log(this.streams[rtspURL] );
            this.streams[rtspURL].start();
            return myPort;
        } catch (error) {
            console.error("Error while instanciating new stream")
        }
    }
