PROGRAM:

NAME

tcmodchain - Query compatibily of transcode modules chains.

SYNOPSIS

tcmodchain [ -m path ] [ -C ] [ -L ] [ -d verbosity ] [ -v ] module1 module2

DESCRIPTION

tcmodchain allow to inspect transcode(1) modules, as well as it's companion, tcmodinfo(1).
While tcmodinfo(1) focus on single modules, tcmodchain is intended to help in
exploring/experimenting module interactions.

OPTIONS

-m path
Look in Path instead of the compiled-in module path while trying to load a module.

-C Enable check mode.
In check mode tcmodchain expects exactly two module identifiers. tcmodchain will
check compatibilty between two given modules. Result will be logged out or not
depending of verbosity level. Anyway, if two modules are compatible, tcmodchain
will exit succesfully; otherwise, tcmodchain will exit with error.
see RETURN VALUES below.

-L Enable list mode.
In list mode tcmodchain expects exactly two module identifiers, exactly one of
which containing a wildcard. tcmodchain will inspect all avalaible installed
modules matching the wildcard and will print out module names that are compatible
with the other given one. if at least one compatible module is found, tcmodchain
will exit succesfully; otherwise, tcmodchain will exit with error.
see RETURN VALUES below.

-d verbosity
Specify the verbosiness level to use, like transcode does. Default value is 1
(TC_INFO verbosiness).

-v Print version information and exit.

MODULE IDENTIFIERS

tcmodchain identifies modules using a type:name naming scheme. Currently, as in transcode
1.1.0, only encode and multiplex module types are supported. name can refer to the name of
any avalaible transcode modules, using the same rules of tcmodinfo(1) -i option. The
wildcard character * is supported in the name section of module identifier. Wildcard
meaning is `any of avalaible modules' and is honoured only when list mode (-L option) is
used. Using wildcard character for both module identifiers will lead to an error.

EXAMPLES

$ tcmodchain -C encode:null multiplex:null -d 1

[encode_null.so] v0.0.3 (2005-06-05) null (fake) A/V encoder
[multiplex_null.so] v0.0.2 (2005-12-29) discard each encoded frame
[tcmodchain] encode:null | multiplex:null [OK]
[tcmodchain] module chain OK

$ tcmodchain -L 'encode:*' multiplex:null

copy
faac
lame
lzo
null
x264
xvid

PLEASE NOTE that output of this example may vary depending of your installation.
At least null and copy modules will be showed on your output.

$ tcmodchain -L encode:null 'multiplex:*'

avi
null
raw
y4m

RETURN VALUES

tcmodchain uses following return values:
0 successfull
1 bad parameter or command line option
2 error while (un)loading a module
3 given module pair isn't compatible
4 error while looking for module(s)
