Simple HLS server in Python using the Flask web framework

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.

from flask import Flask, Response
import subprocess

app = Flask(__name__)

@app.route('/live/<stream_id>.m3u8')
def m3u8(stream_id):
    ffmpeg = subprocess.Popen(['ffmpeg', '-i', 'rtmp://localhost/live/' + stream_id, '-c:v', 'h264', '-c:a', 'aac', '-f', 'hls', '-hls_time', '10', '-hls_list_size', '0', '-hls_flags', 'delete_segments', 'static/' + stream_id + '.m3u8'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    return Response(ffmpeg.stdout, mimetype='application/x-mpegURL')

@app.route('/live/<stream_id>/<int:sequence>.ts')
def ts(stream_id, sequence):
    with open('static/' + stream_id + '/' + str(sequence) + '.ts', 'rb') as f:
        return f.read()

if __name__ == '__main__':
    app.run(debug=True, host='0.0.0.0')

Below is based on the multiple sources :

from flask import Flask, Response

app = Flask(__name__)

@app.route('/live/<stream_id>.m3u8')
def m3u8(stream_id):
    with open(f"static/{stream_id}.m3u8", "r") as f:
        return Response(f.read(), mimetype="application/x-mpegURL")

@app.route('/live/<stream_id>/<int:sequence>.ts')
def ts(stream_id, sequence):
    with open(f"static/{stream_id}/{sequence}.ts", "rb") as f:
        return f.read()

if __name__ == '__main__':
    app.run(debug=True, host='0.0.0.0')

In above example, the Flask application has two routes: /live/<stream_id>.m3u8 and /live/<stream_id>/<int:sequence>.ts. The first route returns the contents of the .m3u8 playlist file for the specified stream. The second route returns the contents of individual .ts segments for the specified stream and sequence number.

To run this server, you'll need to have the Flask web framework installed. The two HLS files should be stored in a static directory and the paths to the .m3u8 playlist files and the .ts segments should match the paths specified in the routes. You can start the server by running the Python script and access the HLS streams by opening http://localhost:5000/live/<stream_id>.m3u8 in a media player that supports HLS.
