## MJPEG Suppt dropped

Render an MJPEG Stream  JPEGs in a HTML < img > tag with the credentials in the Stream URL is not possible due to Chrome security polices.
My first approach was to use chrome.webrequest.onBefeSendHeaders() to add the credentials to the authization header of the HTTP request.
I think this is not the best approach since you need to filter the requests of the addon (cameras) from all request the browser made.
This requires the permission "browsingData" (be able to see all requests from the browser) which does no comply with data protection guidelines.
So we have to use XMLHTTPRequests (fetch) to be able to add credentials to the header.
The only implementation i found was [mjpegreadalestream](https://github.com/aruntj/mjpegreadablestream/blob/master/index.html).
But it was not pefmant enough f daily use.
Their is very little infmation on how to fetch a mjpegreadable stream  render it to an < img > tag.

If you can help me with this topic, dont hesitate to contact me.
