Marathon

Use the live chat to stream loop your videos.

How it works

Requirements: Install FFmpeg

• https://www.ffmpeg.org/download.html

marathon start --twitch-stream-key [twitch stream key. ex: live_XXXX] --twitch-broadcaster-channel [twitch username, ex: justintv]

1. The bot connects to iRc and joins your channel, then wait for commands
2. On !play lotr.playlist => the bot will stream in real time your playlist with FFmpeg ffconcat.
3. On !shutdown => the bot will halt the stream and exits.

Local Mock: RTMP server to HLS stream

Start RTMP server that write an HLS stream

https://ffmpeg.org/ffmpeg-formats.html#toc-hls-2

ffmpeg -f flv -listen 1 -i rtmp://127.0.0.1:1935/live/app  -hls_time 2 -hls_list_size 5 -hls_flags delete_segments -start_number 0 testsrc.m3u8

Start HTTP server to serve HLS stream

Reading the file m3u8 directly on the disk will prevent m3u8.tmp to be swapped with the main one. So the stream stops when reaching the last segments of the main one.

python3 -m http.server 8080

Read the HLS stream

.\ffplay -x 640 -y 360 http://127.0.0.1:8080/testsrc.m3u8

Start a RTPM stream

Use testsrc source.

ffmpeg  -re -f lavfi -i testsrc -f flv rtmp://127.0.0.1:1935/live/app

Or use a playlist with ffconcat

ffmpeg  -re -stream_loop -1 -f concat -i playlist.txt -f flv rtmp://127.0.0.1:1935/live/app
