@ge I have almost the exact environment and Raspberry Pi. I am running MM version 2.33.0, but that should not matter IMHO. Btw, have 8Gb, and you ? vcgencmd get_config total_mem Can you open the RTSP URL in VLC and then open Window - Media Information ? Then the Codec Details tab and please provide the Codec, Video resolution and Frame rate information. I have H.264, 2560x1440, 25. And can you try to change the config to this (add 2 lines): windows: [ { windowSize: { width: 990, height: 557 }, windowPosition: { x: 471, y: 20 }, rtspStreamOverTcp: true, noSound: true, streams: [ 'rtsp://admin:Camadmin@172.16.0.37:554/cam/realmonitor?channel=1&subtype=0' ] } ] From looks the RTSP URL you are using a Dahua cam, right ? Maybe you can try subtype=1 ?? Or another channel perhaps. I do not know the relation between channels and resolutions. Try to find a lesser resolution to see if it makes it better. Also good to know how many other applications are streaming, for example Synology Surveillance Station.

Hello, I think you can use the useVLC in embedded mode In recent forks of MMM-RTSPStream, VLC can be embedded into the browser view with an iframe or HTML5 video tag, which respects DOM positioning. Check the fork you’re using. If it’s still spawning standalone VLC, look for configuration like: localPlayer: ‘ffmpeg’ // instead of ‘vlc’ Some forks added ffmpeg or jsmpeg options to push the stream into a element.
