This rather ridiculous method uses bash, socat, and gstreamer to implement an HTTP-ish server which will serve your video as an MJPEG stream which is playable in browsers.

This approach has the advantage of being relatively low latency (under a second), browser-compatible, and not needing to reencode anything on the CPU (it gets JPEG data from the camera itself). It has the disadvantage of only supporting one viewer at a time. (Though, really, the RTSP examples on this page perform very poorly with multiple viewers, so...)

Compared to HLS, it has the disadvantages that MJPEG requires more bandwidth than h264 for similar quality, pause and seek are not possible, stalled connections cannot jump ahead when they are unstalled, and, in the case of this primitive implementation, it only supports one viewer at a time.

Gstreamer can almost do this by itself, as it has a multipartmux element which produces the headers which precede each frame. But sadly, despite various forum posts lamenting the lack of one over the last 12+ years, as of the end of the 50th year of the UNIX era (aka 2020), somehow nobody has yet gotten a webserver element merged in to gstreamer (which is necessary to produce the HTTP response, which is required for browsers other than firefox to play it). So, here is an absolutely minimal "webserver" which will get MJPEG displaying in a (single) browser.
