Prerequsites

• ffmpeg extension should be installed on the local system to manipulate the streams.
• OBS studio for commencing live stream

Intallation steps

2. npm install
3. npm start

How this code works

1. import tempus-ffmpeg.postman_collection.json postman collection.
2. start stream from the OBS studio
   • Go to preferences/settings
   • Choose Stream option
   • Choose custom stream and set below details
   • server = rtmp://13.68.138.193/live
   • Stream Key = 777
3. Once streaming commenced and node server is running then call http://localhost:3005/api/cameraStream/start-record from the postman collection. This will start recording of ongoing live stream.
4. To end the copy of the stream call http://localhost:3005/api/cameraStream/stop-record API.
5. Once ended it will generate .mp4 file to the root of the app. You can play the file to check whether live stream has beeen recorded or not.

What we want to achieve

Live stream is continuosly recording stream from IP Camera

1. We want to record portion of the stream while calling start-record and end-record API using ffmpeg or any other comand line tool.

Server Details

Server has nginx RTMP module which converts RTMP stream to HLS for streaming over HTTP/S. The server has been configured for each stream to have 3 seconds HLS segments, which, in turn genrates files like https://tempusipsum.com:8081/hls/777-1.ts, 777-2.ts, 777-3.ts and so on for every 3 seconds.

HLS live stream URL has m3u8 format like https://tempusipsum.com:8081/hls/777.m3u8
