man mplayer : environment variables

man mplayer : environment variables [ SOURCE ]

There are a number of environment variables that can be used to control the behavior of MPlayer and MEncoder.

MPLAYER_CHARSET (also see -msgcharset)

Convert console messages to the specified charset ( default : autodetect ). A value of "noconv" means no conversion.

MPLAYER_HOME

Directory where MPlayer looks for user settings.

MPLAYER_VERBOSE (also see -v and -msglevel)

Set the initial verbosity level across all message modules ( default : 0 ). The resulting verbosity corresponds to that of -msâglevel 5 plus the value of MPLAYER_VERBOSE.


libaf :

LADSPA_PATH

If LADSPA_PATH is set, it searches for the specified file. If it is not set, you must supply a fully specified pathname.
FIXME : This is also mentioned in the ladspa section.


libdvdcss :

DVDCSS_CACHE

Specify a directory in which to store title key values. This will speed up descrambling of DVDs which are in the cache. The DVDCSS_CACHE directory is created if it does not exist, and a subdirectory is created named after the DVD's title or manufacturing date. If DVDCSS_CACHE is not set or is empty, libdvdcss will use the default value which is "${HOME}/.dvdcss/" under Unix and "C:\Documents and Settings\$USER\Application Data\dvdcss\" under Win32. The special value "off" disables caching.

DVDCSS_METHOD

Sets the authentication and decryption method that libdvdcss will use to read scrambled discs. Can be one of title, key or disc.

key

is the default method. libdvdcss will use a set of calculated player keys to try and get the disc key. This can fail if the drive does not recognize any of the player keys.

disc

is a fallback method when key has failed. Instead of using player keys, libdvdcss will crack the disc key using a brute force algorithm. This process is CPU intensive and requires 64 MB of memory to store temporary data.

title

is the fallback when all other methods have failed. It does not rely on a key exchange with the DVD drive, but rather uses a crypto attack to guess the title key. On rare cases this may fail because there is not enough encrypted data on the disc to perform a statistical attack, but in the other hand it is the only way to decrypt a DVD stored on a hard disc, or a DVD with the wrong region on an RPC2 drive.

DVDCSS_RAW_DEVICE

Specify the raw device to use. Exact usage will depend on your operating system, the Linux utility to set up raw devices is raw(8) for instance. Please note that on most operating systems, using a raw device requires highly aligned buffers : Linux requires a 2048 bytes alignment ( which is the size of a DVD sector ).

DVDCSS_VERBOSE

Sets the libdvdcss verbosity level.
0 Outputs no messages at all.
1 Outputs error messages to stderr.
2 Outputs error messages and debug messages to stderr.

DVDREAD_NOKEYS

Skip retrieving all keys on startup. Currently disabled.

AUDIODEV

FIXME : Document this.

AUDIOSERVER

Specifies the Network Audio System server to which the nas audio output driver should connect and the transport that should be used. If unset DISPLAY is used instead. The transport can be one of tcp and unix. Syntax is tcp/<somehost>:<someport>, <somehost>:<instancenumber> or [unix]:<instancenumber>. The NAS base port is 8000 and <instancenumber> is added to that.

EXAMPLES :

AUDIOSERVER=somehost:0

Connect to NAS server on somehost using default port and transport.

AUDIOSERVER=tcp/somehost:8000

Connect to NAS server on somehost listening on TCP port 8000.

AUDIOSERVER=(unix)?:0

Connect to NAS server instance 0 on localhost using unix domain sockets.

VIDIXIVTVALPHA

Set this to 'disable' in order to stop the VIDIX driver from controlling alphablending settings. You can then manipulate it yourself with 'ivtvfbctl'.
