binaryoutlook/streamer repository overview

This is docker image built due to the untimely demise of rabb.it It will stream a Chrome window to an icecast server for group viewing.

Based on the following article: https://medium.com/dot-debug/running-chrome-in-a-docker-container-a55e7f4da4a8⁠

Requirements:

• You must have an icecast2 server running.
• To cast to an icecast2 server running on port 8000 on localhost with a username of source, and a password of hackme
• STREAM_URL=icecast://source:hackme@localhost:8000/stream.webm
• Your stream would be visible on "http://localhost:8000/stream.webm⁠"

Usage:

docker run -p 5900:5900 -e STREAM_URL=icecast://... --shm-size=1g --user apps --privileged binaryoutlook/streamer

Once the container is running, connect to VNC on port 5900 and stream.

Currently Icecast must be patched to allow larger than normal EBML Headers due to a change in modern FFMPEG.
