How is the HTML generated/overridden?

Is there any reason why the MPEG streaming code can't emit HTML for the button along with the image?

Yes, the basic principles on which HTTP was designed: one address gives you one document, in this case it's a stream of JPEG images. What you can do is serve your own HTML on one address, and have it embed a different address on which you would serve the stream of JPEG images. It would however require you to either listen on two different ports, or parse the request header to see what address was requested and act accordingly — this would complicate the code a bit.

@deshipu, You were absolutely correct regarding the browser. I ran a test using three(3) different browsers, and each one generated their own HTML interpretation of "Content-Type: image/jpeg". So, that mystery is resolved.

What you can do is serve your own HTML on one address, and have it embed a different address on which you would serve the stream of JPEG images.

Regarding you last post, did you mean serve my own HTML on one URL path and serve the streamed JPEG on another URL path; as shown below?

Yes, something like that should work.
