We are developing a browser based application that streams real-time video up/down (two-way). We are struggling to get consistent 720p30fps WebRTC (H264) streaming quality. Looking for suggestions on ways to improve stability of the browser media.

Would tweaking tcp/udp parameters on sysctl.conf help improve performance? Everything is default now using Jetson Nano JetPack 4.3 Operating System

Are there any specific chrome switches that will help improve H264 video encode/decode performance? Chromium launch switch in use currently:
chromium-browser --alsa-output-device="hw:CARD=Audio" --alsa-input-device="plughw:CARD=Audio" --disable-restore-session-state --window-position=0,0 --start-maximized --window-size=1920,1080 --ignore-gpu-blacklist --start-fullscreen --kiosk --noerrdialogs --disable-translate --no-first-run --user-agent="Mozilla/5.0 (X11; CrOS x86_64 12105.100.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.129 Safari/537.36" --enable-gpu-rasterization --enable-native-gpu-memory-buffers --disable-gpu-compositing --disable-gpu-vsync --ignore-gpu-blacklist --enable-one-copy-rasterizer --enable-checker-imaging --enable-quic --site-per-process --enable-tcp-fastopen --disable-features=MaterialDesignBookmarks --enable-fast-unload --enable-experimental-canvas-features --enable-scroll-prediction --disable-user-media-security -
Should we consider using other browsers besides Chromium?

Would CSI camera have better results compared to USB camera?
… any other pointers on how to improve stability and performnce here?
