flumotion-worker

NAME

flumotion-worker - streaming media server worker

SYNOPSIS

flumotion-worker [ -v ] [ --debug debug configuration ] [ -H host ] [ -P port ] [ -T protocol ] [ -n name ] [ -D ] -u username -p password

DESCRIPTION

flumotion-worker is the part of flumotion that actually performs all the real work of encoding, streaming, etc. In a flumotion system, there will be a single manager, and could be several workers running on different systems (this is useful to distribute the load of, for instance, video encoding). You need to have a minimum of one worker for flumotion to function correctly.

You should start flumotion-manager first, then connect flumotion-worker to the running manager.

OPTIONS

-h, --help

Show a brief help message, then exit.

--version

Show the version number.

-v, --verbose

Be verbose in console output. This is equivalent to setting the debug level to 3, and will override any debug specifiers.

-dDEBUG, --debug=DEBUG

Set the debug configuration to the specified debug string. See the Debugging section for details of this.

-HHOST, --host=HOST

Specify the hostname on which the manager is running.

-PPORT, --port=PORT

Specify the port on which the manager in running (usually 7531 for SSL, or 8642 otherwise)

-TTRANSPORT, --transport=TRANSPORT

Set the transport protocol to use, either 'tcp' or 'ssl'. Default is 'ssl'.

-nNAME, --name=NAME

Set the name for this worker to use in the manager.

-D, --daemonize

Run in the background as a daemon.

-u, --username

Specify the username to use to connect to the manager.

-p, --password

Specify the password to use to connect to the manager.

-FPORTS, --feederports=PORT_FROM:PORT_TO

Specify the range of feeder ports to use in the format 'lower-upper'. These are the ports used for inter-worker communication. If you have multiple workers on seperate systems (perhaps one doing encoding, behind a firewall, and a second doing the streaming outside the firewall), they must be able to communicate using this port range, so you'll have to open these ports in your firewall. It is recommended that you have a range of 20 ports.

DEBUGGING

In the unlikely event of something in flumotion not working, you might want to debug it. The flumotion tools ( flumotion-worker , flumotion-admin , and flumotion-manager ) all alow you to turn on debugging output in two different ways.

Firstly, you can use an environment variable, FLU_DEBUG. Secondly, you can launch the program with a -d or --debug switch. Either approach allows you to specify a debug configuration string with the following syntax:

name1:n1,name2:n2,name3:n3

In this syntax, the 'name' variables can be replaced with the name of a particular module within flumotion (such as 'admin', 'twisted', etc.). You can also use '*' to specify all modules. The 'n' variables are numbers from 1 to 5, larger numbers corresponding to more verbose output (ERROR, WARN, INFO, DEBUG, and LOG). At level 4, full debugging information is emitted.

You can also use an abbreviated form where you just supply a single number, thisuses that debug level for all modules. Thus the simplest way to enable full debug output for all modules is to use '-d 4' on the command line.

A more complex example would be '-d *:3,admin:4' to set the logging level for the admin module to DEBUG, and for all other modules to INFO.

EXAMPLES

Simple example, starting flumotion-worker connecting to a manager using TCP, default host and port, and with the username 'user' and the password 'test'

flumotion-worker -v -T tcp -u user -p test --feederports=8060-8080
