If no module is specified through the -x option, <command>transcode</command> will autodetect them using internal probing code.
|
|
If just one import module is specified, it is used both for video and audio import; if both modules are specified, the first
|
|
is used for video import, the second for audio import.
|
|
To see what import modules are avalaible for your transcode installation, do a
|
|
|
|
<literallayout>
|
|
$ ls -1 $( tcmodinfo -p )/import*.so
|
|
</literallayout>
|
|
|
|
A complete transcode installation has the following import modules.
