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/ossrs/srs cd srs/trunk

Or update the exists code:

git pull

Step 2, build SRS. For detail, read Build

./configure --ffmpeg-tool=on && make

Step 3, 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; http_server { enabled on; listen 8080; dir ./objs/nginx/html; } 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 libfdk_aac; abitrate 45; asample_rate 44100; achannels 2; aparams { } output rtmp://127.0.0.1:[port]/[app]?vhost=[vhost]/[stream]_[engine]; } } }

Step 4, strat SRS. For detail, read HLS

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

Step 5, start encoder. For detail, read HLS

Use FFMPEG to publish stream:

 for((;;)); do \ ./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.flv \ -c copy \ -f flv 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://192.168.1.170:8080/live/livestream_ff.m3u8

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

Step 6, 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 7, play HLS. For detail, read HLS

HLS url: http://192.168.1.170:8080/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.
