When my webcam starts acting up, it will flicker in and out, jump up, down, and sideways, and I'll have a solid second's delay. Any ideas what could be causing problems here?

I am having similar issues on live streaming church programs, glitching etc. Any help would be appreciated. Also having issues with singing on video not single voice it is fine but when the team is up singing audio is terrible. thanks

I seem to have the exact same issues as described above.
Our stream today was terrible: "Number of dropped frames due to insufficient bandwidth/connection stalls: 3044 (90.1%)"
The OBS log file is full of the above error messages:
10:43:01.342: warning: Found EOI before any SOF, ignoring
10:43:01.342: fatal: No JPEG data found in image
10:43:01.343: Error decoding video

My setup is as follows:
2 x PTZ cams via USB
1 x Sony Alpha 6000 via HDMI and HDMI grabber
sound via Yamaha mixer (the only thing that worked :/)
all going into a Dell Latitude E5470 running Windows 10 connected via LAN to a WiFi box and from there via OBS to YT

Because I have 3 USB cams the hint I found here to not deactivate the cams when not visible won't work for me, since then I only can get 2 of the cams to work together with OBS.

Any ideas, suggestions, etc.? I don't want to repeat this terrible experience next Sunday again.

Thanx in advance...
