Hello.

I am mid step in some project. It's time to publish some tips.

Final goal: build a dash camera system for my car.

Status of the day: recording live stream to disk, and network diffusion. Lag is 2.5s.

After digging many things, Raspi tools are not available on Orange Pis. Mplayer sux. So I ended up with the only tool that can read the camera properly: motion.

Hardware:
Orange Pi One with CSI cam and HDMI monitor.

set 9

https://www.aliexpress.com/item/raspberry-pi-3-5-inch-HDMI-LCD-touchscreen-touch-screen-60-fps-high-speed-better-480/32819353553.html?spm=a2g0s.9042311.0.0.27424c4dE39tpD

Software configuration:
- Armbian_5.75_Orangepione_Ubuntu_xenial_default_3.4.113_desktop (full details here : http://www.orangepi.org/orangepi ... ead&tid=4270&extra= ). This is the ONLY Linux image that can work on opiOne+CSI as of today, with ubuntu_lxde_desktop_OrangePipc_v0_9_1.img.xz . For now, 4.19 does not support CSI; I have read 4.21 may bring CSI in ... but the source is uncertain.
- motion
- ffmpeg

Major points:
- control recording of pictures on disk with "output_pictures" (I disabled them to not kill my SD; I will re-enable them later when I receive my High Endurance uSD, a model specific to NVRs)
- control stream diffusion over network with "stream_localhost"
- 'motion -s' will produce normal image files, but ghost/black network video.

Once this conf is set, run the server simply: 'motion -n'

And the client: ffplay -f mjpeg -probesize 32 -i "http://192.168.0.2:8081/"
You can also use VLC as client, but mplayer does not work.

When server dies, ffplay does not suicide; when server comes back; client is stuck on old image. To kill the client, I run this test in a look:
echo -n "" | telnet localhost 8081 2>/dev/null | grep -q "Escape character is" || kill_ffplay.sh
