I had a Raspberry Pi 3B with the PiCam 2 that stopped working. To make the video better, I needed a shroud to prevent picking up light in the room when it was dark outside and ultimately, three PiCam 2’s died while working with that shroud. I ordered a PiCam 3 the other day to see if I could get it to work with my Pi 3B, and alas, it wouldn’t work. So, I used a 2GB Raspberry Pi 4.<\/p>\n\n\n\n

To set up streaming in nginx:<\/p>\n\n\n\n

In your main nginx.conf you need:<\/p>\n\n\n\n

rtmp {\n    server {\n        listen some_ip_address:1935;\n        application live {\n            live on;\n            interleave on;\n\n            hls on;\n            hls_path \/tmp\/hls;\n            hls_fragment 5s;\n        }\n    }\n}<\/code><\/pre>\n\n\n\n
Then in your site config:<\/p>\n\n\n\n
    location \/live\/ {\n        alias \/tmp\/hls\/;\n    }<\/code><\/pre>\n\n\n\n
Your Raspberry Pi should run a recent image. You’ll need to install rpicam-apps<\/strong> to replace rpicam-apps-lite<\/strong> which is installed by default:<\/p>\n\n\n\n
sudo apt-get install rpicam-apps<\/code><\/pre>\n\n\n\n
The script you’ll create a script called livevid:<\/p>\n\n\n\n
#!\/bin\/bash\n\ndate\n\nwhile [ 1 == 1 ]; do\n    rpicam-vid -v 0 -n -t 0 -g 10 --bitrate 2500000 --inline --width 960 --height 540 --framerate 30 --codec libav --libav-format flv --libav-audio 0 --audio-bitrate 8600 --av-sync 200000 -n -o 'rtmp:\/\/url_of_nginx\/live\/cam' --awb daylight\n\ndone;<\/code><\/pre>\n\n\n\n
And your crontab entry (crontab -e)<\/p>\n\n\n\n
@reboot cd \/home\/user;\/usr\/bin\/nohup \/home\/user\/livevid &<\/code><\/pre>\n\n\n\n
With this, you can at least alter the parameters to make the image quality better, or use less bandwidth.<\/p>\n
