This should be a better command ffmpeg -f v4l2 -video_size 1280x720 -i /dev/video0 -pix_fmt nv12 -r 25 -maxrate 1000k -b:v 500k -c:v cedrus264 -f mpegts - | cvlc - --sout "#:rtp{sdp=rtsp://192.168.43.176:8554/go}" 1080p can also be encoded but with 1-2 fps And there are many lags

One another question - can i somehow control exposure time of CAM500B?

I managed to have it all working like this: ffmpeg > udp streaming > vlc > rtsp streaming > motioneye rtsp camera The commands are: ffmpeg -f v4l2 -i /dev/video0 -f mpegts -b:v 5000000 udp://192.168.43.130:1300 cvlc -vvv udp://@192.168.43.130:1300fifo_size=10000 --sout '#rtp{sdp=rtsp://@192.168.43.130:8731/go}' After that i can ad a camera to motioneye and have rtsp video source with huge latency (~5 sec) CPU usage on every core is 40-50% (Nanopi neo air) WITHOUT motioneye (on the other pc). So, only for encoding and streaming. Would be nice to find a solution to encode with Cedrus freeing the CPU cores. With this ffmpeg -f v4l2 -i /dev/video0 -f mpegts -b:v 64k -pix_fmt nv12 -c:v cedrus264 udp://192.168.43.130:1300 FFmpeg starts working but vlc shows [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 10% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 13% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 16% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 20% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 23% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 26% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 30% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 33% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 36% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 40% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 43% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 46% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 50% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 53% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 56% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 60% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 63% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 66% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS [b3a00508] core input debug: Buffering 70% [b380d0e0] packetizer_h264 decoder warning: waiting for SPS/PPS Why i'm doing it? Trying to find a way to achieve more than 1-3 fps with camera board on Nanopi for biggest resolitions with built-in motion detection and video saving.

Thank you. I can see it is complex, so maybe you could provide me a command to convert from YUV420 to H264 from one device to another using v4l2loopback. That would save me much time i think.

These don't work for me at the moment because "Tools for Raspberry" don't compile on H3 platform.

That works, so we need YUV420P. What do you think about this? https://github.com/mpromonet/v4l2tools v4l2compress_omx : read YUV420 from a V4L2 capture device, compress in H264 format using OMX and write to a V4L2 output device

I can see that configuration file for my wlan connection is located in /etc/NetworkManager/system-connection Maybe it will also work if we make that file before the first boot.

Regarding streaming - thanks for the link but the question is more about how to "produce" the stream on device, like making rtsp camera from nanopi. So it's usable with motioneye or zoneminder. Sorry if i was unclear.

Already tried editing the file and modules list, after that /dev/video0 appeared but not working with software. Will try it one more time. Regarding wifi - the stable image here https://www.armbian.com/nanopi-neo-air/ don't have nmtui installed, or at least a week ago it hadn't. Development version does.

Hello is there any way to stream rtsp on H3 devices? With this i can record video ffmpeg -t 30 -f v4l2 -channel 0 -video_size 1280x720 -i /dev/video0 -pix_fmt nv12 -r 30 -b:v 64k -c:v cedrus264 test.mp4 My hardware is NanoPI neo air + CAM500B. Using friendlyARM's image at the moment because camera don't work on Armbian. (/dev/video0 is there but mjpg-streamer end with errors for example)

Hello @lvmc i think as a new user i can't send you a PM... Can you please give me some information about modules with wider lense for NEO Air? Could be interesting for my project. Thanks
