collective.transcode.daemon 0.5

Video transcoding daemon

collective.transcode.daemon is an XML-RPC daemon servicing requests for transcoding jobs.

It was initially developed during the Plone Video Sprint that took place right after the Plone Conference 2009 in Budapest. It was based on the darksnow.convertdaemon code but has evolved a lot since

• https://svn.atreal.net/public/svn.darksnow.org/ConvertDaemon

It’s currently used for video transcoding in Plumi 3.0 and 3.1 and is a part of the collective.transcode.* suite for Plone 3.x & 4.x.

• http://plumi.org

• http://pypi.python.org/pypi/collective.transcode.star

Requirements

Apart from what is assembled by the buildout, the following dependencies must be installed manually for the transcoding scripts to work:

• ffmpeg with x264 support

• ffmpeg2theora

The daemon has been tested with Python2.4 and Python2.6.

Installation

The instructions below are for setting up a standalone transcode daemon.

If you want a complete transcoding solution for the Plone CMS use collective.transcode.star

The best way to install a standalone daemon is to use zc.buildout and the buildout.cfg file provided

python2.6 bootstrap.py
./bin/buildout
...
./bin/transcodedaemon fg
Initializing
Launched http channel
Launched TranscodeDaemon scheduler thread....

Configuration

You can edit the following options in buildout.cfg:

listen_host
    hostname to listen

listen_port
    port to use

videofolder
    relative path of folder where transcoded videos are stored

secret
    a secret shared key used for authentication and encryption

profiles
    a python list of dicts specifying the supported transcoding profiles

Don’t forget to run ./bin/buildout after editing buildout.cfg

You can also customize the transcoding scripts inside the scripts directory.
