If you are looking for a lightweight way to offer a presentation for your RTMP and RTSP streams this project may assist. The project is based on the usage of cameras that support RTMP streams (and with a helper RTSP streams).
Recording for more of a nvr type setup is also possible. Largest deployment is 250+ cameras running Debian with the following hardware specifications:
Note
Hardware specifications will vary based on each setup.
Note
The addition of the 8TB ssd is for recording four days of history on the cameras. This system has cameras from four locations. Enabling the recording does put extra work on the single worker process. To address any potential bottleneck issues I took the liberty to put each of the four locations in an isolated container using https://tracker.debian.org/pkg/open-infrastructure-compute-tools with a bind to each container for storage. I have seen no performance issues with this configuration.
Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz.
32gb ram
2TB ssd
8TB ssd
Become root user:
sudo -i
Install some things I find helpful in container setups and the nginx and nginx-rtmp-module:
apt install build-essential ffmpeg vim git nginx libnginx-mod-rtmp
Clone the repo:
git clone https://github.com/unixabg/rtmp-nginx-viewer.git
Change directory to the project:
cd rtmp-nginx-viewer
Install the project:
make install
Add your cameras to the /etc/nginx/cameras.conf and be mindful for the camera name to use something like MyCamName or My_Cam_Name (* use only camel or snake naming *). The reason for the naming conventions is that if you want the recordings feature an improper naming will break the regex call I am making in the code to present the videos. If you have a lot of cameras best to be overly descriptive like MyDrivewayWest222, this will help provide a granular search and not overwhelm your browser.
Restart nginx:
systemctl restart nginx
If you want the nvr features below is the general outline. Create a the folder for video recording storage:
mkdir -p /videos/recordings
Set the permissions so nginx can write to the folder:
chown -R www-data: /videos
Edit the installed /etc/nginx/nginx.conf and unremark the recording section. Edit the installed /etc/nginx/sites-enabled/default and unremark the /recordings location.
Install ffmpeg:
apt install ffmpeg
Restart nginx:
systemctl restart nginx
I have added a kiosk feature that utilizes the kiosk.html file for calling a given camera group to be displayed with something like:
kiosk.html?cams=Camera0,Camera31,Cam7&refresh=3
The above should compose the cameras in the specified order and in an automatic grid on the browser.
