## :whale:[docker-nginx-rtmp-ffmpeg](https://hub.docker.com/repository/docker/ar414/nginx-rtmp-ffmpeg)
[简体中文](./CN-README.md)
### Support
[](https://www.jetbrains.com/?from=nginx-rtmp-ffmpeg)
Based on the configuration and deployment of [docker-nginx-rtmp](https://github.com/alfg/docker-nginx-rtmp)the meaning of this article is to realize live streaming and live screen watermarking.
* Nginx 1.16.1（Stable version compiled from source code）
* nginx-rtmp-module 1.2.1（Compile from source）
* ffmpeg 4.2.1（Compile from source）
* Configured [nginx.conf](https://github.com/ar414-com/nginx-rtmp-ffmpeg-conf/blob/master/nginx.conf)
* Only support 1920*1080 (if you need to support other resolutions, please refer to [nginx.conf](https://github.com/alfg/docker-nginx-rtmp/blob/master/nginx.conf)）
* Realize two-way shunt
* localhost
* Live cloud provider（例：AWS）
* Realize live watermark effect
* Watermark image storage location (in the container)：/opt/images/logo.png
## :computer:Deploy and run
### Server
* Install docker (Centos7, other systems please use your search function)
```bash
$ yum -y install docker #install docker
$ systemctl enable docker #Configure startup
$ systemctl start docker #Start the docker service
```
* Pull the docker image and run
```bash
$ docker pull ar414/nginx-rtmp-ffmpeg
$ docker run -it -d -p 1935:1935 -p 8080:80 --rm ar414/nginx-rtmp-ffmpeg
```
* Push stream address（Stream live content to）：
```
rtmp://<server ip>:1935/stream/$STREAM_NAME
```
* SSL certificate
Copy the certificate to the container, and modify the nginx.conf configuration file in the container, and then re-commit (all the files in the container need to be re-committed to take effect)
```
#/etc/nginx/nginx.conf
listen 443 ssl;
ssl_certificate /opt/certs/example.com.crt;
ssl_certificate_key /opt/certs/example.com.key;
```
### OBS configuration
* Stream Type: `Custom Streaming Server`
* URL: `rtmp://<server ip>:1935/stream`
* Stream Key：ar414
### Watch test
> HLS playback test tool：http://player.alicdn.com/aliplayer/setting/setting.html （If a certificate is configured, use https）
* HLS playback address
* With watermark：http://\<server ip>:8080/hls/ar414_wm.m3u8
* No watermark：http://\<server ip>:8080/hls/ar414.m3u8
> RTMP test tool：[PotPlayer](https://daumpotplayer.com/download/)
* RTMP playback address
* No watermark：rtmp://\<server ip>:1935/stream/ar414
* With watermark：Need to be diverted to other servers
## :page_facing_up:Brief explanation of configuration file (diversion, watermark and watermark position)
> [Full configuration file](https://github.com/ar414-com/nginx-rtmp-ffmpeg-conf/blob/master/nginx.conf)
* RTMP configuration
```bash
rtmp {
server {
listen 1935; #port
chunk_size 4000;
#RTMP Live streaming configuration
application stream {
live on;
# Add watermark and diversion, this time it is convenient to test diversion directly to the current server hls
# Actual production is generally diverted to the live cloud（AWS）
# Just replace the address that needs to be diverted
# With watermark：rtmp://localhost:1935/hls/$name_wm
# No watermark：rtmp://localhost:1935/hls/$name
exec ffmpeg -i rtmp://localhost:1935/stream/$name -i /opt/images/ar414.png
-filter_complex "overlay=10:10,split=1[ar414]"
-map '[ar414]' -map 0:a -s 1920x1080 -c:v libx264 -c:a aac -g 30 -r 30 -tune zerolatency -preset veryfast -crf 23 -f flv rtmp://localhost:1935/hls/$name_wm
-c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 2500k -f flv -g 30 -r 30 -s 1920x1080 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name;
}
application hls {
live on;
hls on;
hls_fragment 5;
hls_path /opt/data/hls;
}
}
}
```
* If you need to push multiple live clouds, copy multiple exec ffmpeg as follows：
```bash
application stream {
live on;
#Shunt to local hls
exec ffmpeg -i rtmp://localhost:1935/stream/$name -i /opt/images/ar414.png
-filter_complex "overlay=10:10,split=1[ar414]"
-map '[ar414]' -map 0:a -s 1920x1080 -c:v libx264 -c:a aac -g 30 -r 30 -tune zerolatency -preset veryfast -crf 23 -f flv rtmp://localhost:1935/hls/$name_wm
-c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 2500k -f flv -g 30 -r 30 -s 1920x1080 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name;
#Diverted to Tencent Cloud
exec ffmpeg -i rtmp://localhost:1935/stream/$name -i /opt/images/ar414.png
-filter_complex "overlay=10:10,split=1[ar414]"
