eventstreamr

Single and multi room audio visual stream management.

Installation

Your best bet is to install using cpanm + local::lib. This will install everything under your user directory and will avoid polluting your system perl libraries. It's also how PLUG + LCA use it.

Grab cpanm + local::lib

$ sudo apt-get install cpanminus liblocal-lib-perl

Configure local::lib if you haven't already done so:

$ perl -Mlocal::lib >> ~/.bashrc
$ eval $(perl -Mlocal::lib)

Install from CPAN

cpanm App::EventStreamr

Configuration

You can run through the host configuration wizard with '--configure'.

$ eventstreamr --configure
Welcome to the EventStreamr config utility

It will clear the current config, is this ok? y/n [n]: y

Concepts

A station can have one or more roles. Only one controller can manage stations.

Roles

• controller - Web based frontend for managing stations
• ingest - alsa/dv/v4l capture for sending to mixer
• mixer - DVswitch/streaming live mixed video. With the intention for this to be easily replaced by gstswitch
• stream - stream mixed video
• record - stream mixed video
• sync - rsync files to a central server (requires keyless ssh to be configured)

Directories

• baseimage - docs, notes, and tools for the base (OS) image
• station - station management scripts
• controller - controller stack

Station Script Requirements

See package.deps for list of packages required

Known Issues

A list of known issues that cause minor problems, but have workarounds.

Daemon dies when alsa device isn't present on start

• Ensure all configured ALSA devices are plugged in on boot

Correctly Restart on Date Change

• Reboot or Restart the EventStreamr Daemon (pressing update from the controller will restart it)
