Repository files navigation



avbroadcast republishes media streams for mass consumption. It is a wrapper around the fine ffmpeg and packager programs, so it is standing on the shoulders of giants.


Please note some of its functionality is based on the new HTTP upload feature of Shaka Packager which is a work in progress. It is currently living in the http-upload branch and is being tracked at issue #149.

Please use the beta-build packager-linux for your own experiments, which is also available through the corresponding Docker baseline image.

Getting started


If you know your way around Python, installing this software is really easy:

pip install avbroadcast

Please refer to the virtualenv page about further guidelines how to install and use this software.


Ingest media stream:

avbroadcast ingest \
    --stream="rtmp://" \
    --base-port=50000 \

Package using HLS and publish to HTTP server:

avbroadcast publish \
    --name="bigbuckbunny" \
    --base-port=50000 \
    --target="http://localhost:6767/hls-live" \

Altogether now:

avbroadcast io \
    --name="bigbuckbunny" \
    --stream="rtmp://" \
    --target="http://localhost:6767/hls-live" \

Watch output directory:

avbroadcast watch --path=/var/spool/hls-local

Usage with Docker

Build Docker image "mediatoolbox/avbroadcast:analyzer":

make build-docker-image

You might want to skip this step as Docker images are already available at

Make alias for easy access:

# Use avbroadcast shipped with Docker image.
alias avbroadcast='docker run --name avb --interactive --tty --rm mediatoolbox/avbroadcast:analyzer avbroadcast'

# Alternatively, use avbroadcast from working tree.
alias avbroadcast='docker run --name avb --volume `pwd`:/avbroadcast --interactive --tty --rm mediatoolbox/avbroadcast:analyzer avbroadcast'

Pre-flight check:

avbroadcast --version

Attach to running transcoder:

docker exec --interactive --tty avb /bin/bash

Usage with tmux

avbroadcast ... --tmux --analyze

Attach to Docker container and tmux manager at once:

docker exec --interactive --tty avb tmux attach -t avb

Quit pipeline either by detaching from tmux:


or exit each program individually by typing:


In both cases, the Docker container will stop - and also self-destroy when running with --rm.
