Is it possible to pull header from mjpeg-broadcast?

Question

JavaScript

A link to the mjpeg broadcast comes from the server
(for example: http://address:port/online/mjpeg/start/f62fce8f-7d24-4529-a33c-6b104b6a82b5/0?),
which I feed in html:
html: along with the video in header comes with the stream ID that I need to interrupt the broadcast. The stream ID is dynamic, and if we first get the video, and then request the header using a separate method, it will change. The question is how to get the correct ID if the broadcast starts at
<img class="video" src={{src}}>
