Re: Pi-to-Pi Low Latency One-To-Many Video Streaming. These are not available for bullseye. RedMarsBlueMoon Your total latency will that + the latency (half ping time) from your Pi to the remote server + delay added by the HTTP server + latency from the remote server to the remote client + buffering at the remote client. But apart from that it will definitely be a huge difference to MJPG webcams. 151:8554/stream1 -vf "setpts=N/30" -fflags nobuffer -flags low_delay -framedrop [tcp I use bullseye on my RTSP server, but VLC still plays RTSP on Bookworm. I did try to stream out RTSP using the method described in above page and with 960/720 resolution with 30fps CPU load on PI Zero does not exceed 25% with 1-2. Buster I'm facing the same issue - trying to get low latency streaming. We will use raspi-vid and MediaMTX to capture a video from Camera Module V3. As well as taking a few landscape shots and just generally playing about with it, the first real project was to set it up as a High Quality webcam for video conference meetings. I didn't realise a licence issue has raised its head again. I just didn't know the ffplay options -fflags nobuffer -flags low_delay as I normally only use vlc and rtang wrote:I've implemented a simple RTSP server that forwards RTP packetized H264 packets: I received some questions regarding my implementation, so I figured I might as well make a post here. Relatively low latency streaming with the raspi cam is possible with, say, 100ms. As you have mentioned here that you have done so. As regards your other question, I don't really understand why the latency should be different. Views expressed are still personal views. 4G ping time is about half of 3G, so that might save about 100ms.
