v1_EN_SampleTranscode2HLS

Transcode for HLS deploy example

HLS required h.264+aac, user can transcode for other codecs.

Pure audio HLS, read HLS audio only

Suppose the server ip is 192.168.1.170

Step 1, get SRS. For detail, read GIT

git clone https://github.com/simple-rtmp-server/srs
cd simple-rtmp-server/trunk

Or update the exists code:

git pull

Step 2, build SRS. For detail, read Build

./configure --disable-all \
    --with-ssl --with-hls --with-nginx \
    --with-ffmpeg --with-transcode && make

Step 3, start nginx to delivery hls(m3u8+ts). For detail, read HLS

sudo ./objs/nginx/sbin/nginx

Note: Ensure nginx is ok, to access nginx.

Step 4, config srs. For detail, read HLS

Save bellow as config, or use conf/transcode2hls.audio.only.conf:

# conf/transcode2hls.audio.only.conf
listen              1935;
max_connections     1000;
vhost __defaultVhost__ {
    hls {
        enabled         on;
        hls_path        ./objs/nginx/html;
        hls_fragment    10;
        hls_window      60;
    }
    transcode {
        enabled     on;
        ffmpeg      ./objs/ffmpeg/bin/ffmpeg;
        engine ff {
            enabled         on;
            vcodec          copy;
            acodec          libaacplus;
            abitrate        45;
            asample_rate    44100;
            achannels       2;
            aparams {
            }
            output          rtmp://127.0.0.1:[port]/[app]?vhost=[vhost]/[stream]_[engine];
        }
    }
}

Step 5, strat SRS. For detail, read HLS

./objs/srs -c conf/transcode2hls.audio.only.conf

Step 6, start encoder. For detail, read HLS

Use FFMPEG to publish stream:

    for((;;)); do \
        ./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.200kbps.768x320.flv \
        -vcodec copy -acodec copy \
        -f flv -y rtmp://192.168.1.170/live/livestream; \
        sleep 1; \
    done

Or use FMLE to publish:

FMS URL: rtmp://192.168.1.170/live
Stream: livestream

The stream in SRS:

• RTMP URL: rtmp://192.168.1.170/live/livestream
• Transcode RTMP: rtmp://192.168.1.170/live/livestream_ff
• Transcode HLS: http://192.168.1.170/live/livestream_ff.m3u8

Note: we can use another vhost to output HLS, other codecs transcode then output to this vhost.

Step 7, play RTMP. For detail, read HLS

RTMP url is: rtmp://192.168.1.170:1935/live/livestream_ff

User can use vlc to play the RTMP stream.

Or, use online SRS player: srs-player-ff

Note: Please replace all ip 192.168.1.170 to your server ip.

Step 8, play HLS. For detail, read HLS

HLS url: http://192.168.1.170/live/livestream_ff.m3u8

User can use vlc to play the HLS stream.

Or, use online SRS player: jwplayer-ff

Note: Please replace all ip 192.168.1.170 to your server ip.
