Nginx: Konfigurasi RTMP dengan HLS dan Dash

Untuk mendukung HLS & Dash, kita perlu mengubah sedikit konfigurasi nginx.conf

vi /usr/local/nginx/conf/nginx.conf

ubah agar

http {

    server {

        listen      80;

        location /hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root /tmp;
            add_header Cache-Control no-cache;
        }

        location /dash {
            # Serve DASH fragments
            root /tmp;
            add_header Cache-Control no-cache;
        }
    }
}

Kita butuh menambahkan folder tmp/dash and tmp/hls di root folder untuk nginx.

mkdir /tmp/hls
mkdir /tmp/dash
chmod -Rf 777 /tmp/hls
chmod -Rf 777 /tmp/dash

Juga di bagian rtmp:

rtmp {

    server {

        listen 1935;
        chunk_size 4000;

        application live {
            live on;
            record off;
        }

        application hls {
            live on;
            hls on;
            hls_path /tmp/hls;
        }

        # MPEG-DASH is similar to HLS

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;
        }
    }
}

Contoh lain untuk hls

location /hls/ {
    hls;  # Use the HLS handler to manage requests

    # serve content from the following location
    alias /var/www/video;

    # HLS parameters
    hls_fragment  	        8s;
    hls_buffers         	10 10m;
    hls_mp4_buffer_size 	1m;
    hls_mp4_max_buffer_size 5m;
}

Contoh sederhana untuk men-stream sebuah video .avi menggunakan ffmpeg:

ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
    -f flv rtmp://localhost:1935/hls/movie

atau

avconv -loglevel verbose -re -i movie.avi  -vcodec libx264
    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
    -f flv rtmp://localhost:1935/hls/movie

ffmpeg -loglevel verbose -re -i source.mp4 -c:v libx264 -crf 19
    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
    -f flv rtmp://localhost:1935/hls/movie

Default playlist address pada setup ini adalah:

http://server.ip/hls/StreamKey.m3u8 

contoh

http://192.168.0.3/hls/movie.m3u8 

StreamKey pada contoh ffmpeg commandline di atas adalah “movie”. Ingat, address rtmp address selalu rtmp://ip/ApplicationName/StreamKey.

Sisi Client

Di sisi client tampaknya kita perlu menginstalasi CODEC khususnya untuk mendukung H.264.
