IMPORT MODULES

       If no module is specified through the -x option, transcode 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

		      $ ls -1 $( tcmodinfo -p )/import*.so

       A complete transcode installation has the following import modules.

       alsa [audio]
	   This module reads audio samples from an ALSA device using libalsa.

	   This module accepts the following options:

	   device (string)
	       selects ALSA device to use for capturing audio.

       bktr [video]
	   This module reads video frames from an capture device using bktr module. This module is designed to work on *BSD. For linux, use the
	   v4l module.

	   This module accepts the following options:

	   tunerdev (string)
	       help: selects tuner device.

	   vsource (string)
	       selects video source (device dependant input).

	   format (string)
	       selects video normalization.

	   asource (string)
	       selects audio source (device dependant input).

       dvd [video, audio, extra]
	   This module provides access to DVD content using libdvdread, directly from DVD device. (e.g. on-the-fly operation, no intermediate disk
	   storage needed).

	   At run time, this module requires: libdvdread >= 0.9.3

	   This module accepts the following options:

	   delay (integer)
	       set device access delay (seconds).

       im [video]
	   This module reads single images from disk using ImageMagick; a stream of correlated images can be automatically read if their filenames
	   contains a common prefix and a serial number. All formats supported by ImageMagick are supported as well.

	   At run time, this module requires: libMagick >= 6.2.4.0

	   This module accepts the following options:

	   noseq (flag)
	       disable internal auto loading of images with similar names.

       pv3 [video, audio]
	   This module provides access to Earth Soft PV3 audio/video streams using win32 binary codecs and an internal win32 emulation layer (NO
	   wine needed).

	   At run time, this module requires: PV3 win32 dlls.

	   This module accepts the following options:

	   dllpath (string)
	       set path/filename to load dv.dll from

       vag [audio]
	   This module decodes VAG-format audio (from PlayStation).

	   This module accepts the following options:

	   blocksize (integer)
	       stereo blocking size.

       vob [video, audio]
	   This module imports audio/video from VOB files. If you need direct DVD access, use import_dvd module.

	   This module accepts the following options:

	   nodemux (flag)
	       skip demuxing processing stage. This sometimes improves A/V sync.

       x11 [video]
	   This module captures video frames from X window system using libX11.

	   At run time, this module requires: libcx11-6 >= 1.0.0

	   This module accepts the following options:

	   skew_limit (integer)
	       maximum frame A/V skew (ms) before correction attempt

       v4l2 [video, audio]
	   This module allow to capture video frames through a V4L2 (V4L api version 2) device. While audio capturing is possible, this kind of
	   usage is discouraged in favour of OSS or ALSA import modules.

	   This module accepts the following options:

	   overrun_guard (integer)
	       flag (default off). Toggles the buffer overrun guard, that prevents crash when capture buffers are full.

	   resync_margin (integer)
	       threshold audio/video desync (in frames) that triggers resync once reached.

	   crop (string)
	       forces cropping into selected window (format: WIDTHxHEIGHT+LEFTxTOP)

	   resync_interval (integer)
	       checks the resync_margin every given amount of frames.

	   format (integer)
	       forces video frames convertion by using index; use -1 to get a list of supported conversions.

	   format (string)
	       forces output format to given one; use "list" to get a list of supported formats.

	   convert (integer)
	       forces video frames convertion by using index; use -1 to get a list of supported conversions.
