.SH DESCRIPTION
|
|
.B 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.
|
|
.SH OPTIONS
|
|
.TP
|
|
\fB-m\fP \fIpath\fP
|
|
Look in \fIPath\fP instead of the compiled-in module path while
|
|
trying to load a module.
|
|
.TP
|
|
.B -C
|
|
Enable \fIcheck\fP mode.
|
|
.br
|
|
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.
|
|
.br
|
|
see RETURN VALUES below.
|
|
.TP
|
|
.B -L
|
|
Enable \fIlist\fP mode.
|
|
.br
|
|
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.
|
|
.br
|
|
see RETURN VALUES below.
|
|
|
|
.TP
|
|
\fB-d\fP \fIverbosity\fP
|
|
Specify the verbosiness level to use, like transcode does. Default value
|
|
is 1 (TC_INFO verbosiness).
|
|
.TP
|
|
.B -v
|
|
Print version information and exit.
|
|
.SH MODULE IDENTIFIERS
|
|
.B tcmodchain
|
|
identifies modules using a
|
|
\fItype:name\fP
|
|
naming scheme. Currently, as in transcode 1.1.0, only \fIencode\fP and \fImultiplex\fP
|
|
module \fItype\fPs are supported. \fIname\fP can refer to the name of any avalaible
|
|
transcode modules, using the same rules of tcmodinfo(1) \fI-i\fP option.
|
|
The wildcard character \fI*\fP is supported in the \fIname\fP section of module
|
|
identifier. Wildcard meaning is `any of avalaible modules' and is honoured only
|
|
when \fIlist\fP mode (-L option) is used. Using wildcard character for \fIboth\fP
|
|
module identifiers will lead to an error.
|
