I have a Logitech C920 with a Pi4 connected via gigabit to a decently powered desktop and would love to take advantage of the power to get a 1080P/30FPS feed from the camera. After looking at the list I set my parameters to
-r 1920x1080 -f 30. This works great generally but when on the control view of Octoprint, my desktop browser slows to a crawl and the stream framerate gradually degenerates until it freezes (I believe the PI is relatively unaffected). The network utilization is about 70mbps. I believe this is due to the images saturating the link (perhaps the NIC on the PI) and the browser makes sure it has all of the image data, even those it missed.
Does anyone have any suggestions to either get a full 1080/30 feed or to have a low-resolution high-framerate feed but also have high-resolution for time-lapses?
It also is an older version of the c920 that does include onboard H.264 encoding and it would be amazing to utilize that, but I have spent many nights trying to get it to work to no avail.
