RTP to HLS

This project demonstrates handling RTP streams and converting them to HLS streams.

The whole idea has been described in this blog post.

Running the demo

To run the demo, you'll need to have Elixir installed. Then, run

elixir rtp_to_hls.exs

After a while, the server will start listening for UDP connections on port 5000. Then, start the RTP stream with

elixir send.exs

When the server prints that playback is available, visit http://localhost:8000/stream.html and you should see the stream there. The stream can be also played with players other than the browser, like vlc or ffplay, for example

ffplay http://localhost:8000/output/index.m3u8

The RTP stream can be sent with other tools as well, for example with GStreamer:

gst-launch-1.0 -v audiotestsrc ! audio/x-raw,rate=44100 ! faac ! rtpmp4gpay  pt=127 ! udpsink host=127.0.0.1 port=5000 \
    videotestsrc ! video/x-raw,format=I420 ! x264enc key-int-max=10 tune=zerolatency ! rtph264pay pt=96 ! udpsink host=127.0.0.1 port=5000
