Same issue with my personal ffmpeg script. So maybe something that could be worked around rtmp?

This is not unexpected with WiFi. A lot of WiFi networks experience congestion especially in the pandemic with so many home offices. This congestion isn't noticed while watching (consuming) video due to more extensive buffering.

I've tested with OBS studio. With OBS this issue doesn't happen... Only with ffmpeg/pylivestream. Seems OBS devs might have workarounded it or something.
