In this example, the Flask application has two routes: /live/<stream_id>.m3u8 and /live/<stream_id>/<int:sequence>.ts. The first route uses the ffmpeg command-line tool to convert an RTMP stream into an HLS stream, and returns the contents of the .m3u8 playlist file. The second route returns the contents of individual .ts segments. To run this server, you'll need to have the Flask web framework and the ffmpeg command-line tool installed. You can start the server by running the Python script and access the HLS stream by opening http://localhost:5000/live/<stream_id>.m3u8 in a media player that supports HLS. |
