docker-rtmp-nvenc

A docker gateway container between your PC and streaming services (Twitch, YouTube...), using NVENC as encoder.

Prerequisites

To use NVENC, you need a compatible Nvidia card⁠ and the NVIDIA Container Toolkit⁠ for Docker⁠ to be setup properly.

How to run

docker run -d --runtime nvidia --name rtmp-nvenc -p 1935:1935 e7db/rtmp-nvenc

Test with OBS Studio and VLC

In OBS, use the following settings:

• Stream type: Custom Streaming Server
• URL: rtmp://<ip_of_host>/local
• Stream key: test

Start streaming, then, go to VLC and and test your stream with the URL rtmp://<ip_of_host>/live/test.

Remember to replace <ip_of_host> with your server IP.

Go live

Multiple default NVENC-based configurations are available for the following platforms:

• Facebook Live, using rtmp://<ip_of_host>/facebook
• Mixer, using rtmp://<ip_of_host>/mixer
• Twitter Periscope, using rtmp://<ip_of_host>/periscope
• Restream, using rtmp://<ip_of_host>/restream
• Twitch, using rtmp://<ip_of_host>/twitch
• YouTube, using rtmp://<ip_of_host>/youtube

Go live with custom settings

You can also use custom settings, to go Live on another platform or with any specific encoder settings you want. you can also use standard CPU-based x264 if you prefer.

For example, you could go live on Twitch with 4MBps bitrate using the following configuration:

application twitch {
    live on;
    exec_push ffmpeg -hwaccel cuvid -c:v h264_cuvid -i rtmp://localhost/twitch/$name -vsync 0 -c:a copy -c:v h264_nvenc -preset hq -profile high -rc cbr -b 4M -bufsize 4M -f flv rtmp://live.twitch.tv/app/$name >>/dev/stdout 2>&1;
}

You can then use this specific configuration by starting the container like this:

docker run -d --runtime nvidia --name rtmp-nvenc -p 1935:1935 -v /path/to/custom.conf:/etc/nginx/rtmp-conf.d/custom.conf e7db/rtmp-nvenc
