mjpg-streamer periodically starts dropping frames like crazy, even though I'm on a high-bandwidth wifi connection, and CPU and memory use are not pegged - not even close.
Others have seen this problem with mjpg streamer, and the dev can't isolate the problem.
Since the camera already outputs an mjpeg stream, is there any reason I can't direct that directly into the Octoprint UI? Any pointers to getting started?
Camera model
Nexigo 980P USB web cam, formats from 320x240 to 60P HD, streaming from index0: RGB mjpeg stream.
What is the problem?
Camera already outputs mjpeg stream. Can I bypass mjpg-streamer?
Camera works beautifully - except when it doesn't - there's a likely mjpg-streamer issue, which others have reported.
What did you already try to solve it?
Tuning camera settings to try to prevent mjpg slowdown

- It seems that you don't have VL805 (Raspberry Pi 4).
There should be no problems with USB (a.k.a. select() timeout)
