NAME
flixd - Flix encoding daemon
SYNOPSIS
flixd [ -d ] [ -p port ] [ -i interface ] [ -r ] [ --max-sessions snct
] [ --authdir path ] [ --pidfile file ] [ --logfile file ] [ --loglevel
level ]
flixd [ -h ] [ -v ]
DESCRIPTION
flixd is an rpc-based flix encoding server. As such, portmap MUST be
running for it to operate. The port and interface to listen on can be
specified using the --port and --interface options. By default flixd
will allow the rpc service to bind to any available port and interface.
A port is usually specified to bypass the necessity for a connection to
portmap by a client.
By default flixd will allow an unlimited (except by available
resources) number of encoding sessions. This behavior can be modified
by specifying the --max-sessions option with a count >0. Any sessions
that start an encode after the count is reached will be queued.
flixd will look for authentication files (flixengine.lic, provided by
On2 at the time of install) in the user's home directory unless a path
is specified with the --authdir option. The default install location is
$HOME/.on2.
flixd can be stopped by sending it the TERM signal. The pid can be
stored for this purpose in a file by giving the --pidfile option.
By default, when running as a daemon, flixd will log using syslog(3). A
log file can be specified by using the --logfile option. The amount of
logging can be adjusted using the --loglevel option.
OPTIONS
-h,--help
Prints a summary of available command line options and exits.
-v,--version
Prints version information and exits.
-d debug mode; do not daemonize
-p,--port port
port to listen for rpc connections on (default: any)
-i,--interface interface
interface to bind rpc socket to. Argument may be a numeric IPv4
address or device name; --port MUST be specified when using this
option (default: any available)
-r,--reuseaddr
Set SO_REUSEADDR socket option on listen socket. Only meaningful
when used in conjunction with the --port option
--max-sessions snct
max number of concurrent encoding sessions (default: -1, unlim-
ited)
--authdir path
path to search for flixd authorization files (default: user's
home directory)
--pidfile file
write pid to file; e.g., /var/run/flixd.pid
--logfile file
file to log messages to (default: debug mode: stderr, daemon
mode: use syslog(3))
--loglevel level
logging verbosity (0-4, 0: none, 1: errors, 2: status, 3: debug,
4: heavy), the levels are cumulative. (default: 2, errors+infor-
mational)
ENVIRONMENT
flixd's behavior is affected by the following environment variables.
FLIXD_MENCODER
This variable specifies the path to mencoder that flixd should
use during transcoding. By default flixd allows the system to
locate mencoder via the PATH environment variable. Therefore
this variable is useful if you have installed mencoder to a non-
standard location or have multiple versions of mencoder
installed. For example, if you have installed mencoder to
/opt/on2/flixengine/bin you would set FLIXD_MEN-
CODER=/opt/on2/flixengine/bin/mencoder to ensure this version is
used during transcoding.
FLIX_OGG_PHYMEM_PCTMAX
This variable controls the maximum amount of physical memory any
one encode instance's ogg demuxer will use. This is to prevent a
possible segmentation fault due to unchecked memory allocations
within libogg. This value is given as an integer percent, e.g.,
FLIX_OGG_PHYMEM_PCTMAX=50, will limit the demuxer's memory usage
to 50% of available physical memory. If left unset or set to 0
the only upper bound is that imposed by the system itself. A
reasonable target is 400-500MB.
HOME When --authdir is omitted HOME is used as the authorization
directory.
TMPDIR Temporary file location. If unset /tmp is used.
