<title>import modules</title>
<para>
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.
