.SH "IMPORT MODULES"
.PP
If no module is specified through the \-x option,
\fBtranscode\fR
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
.sp
.RS 4
.nf

.fi
.RE
.sp
A complete transcode installation has the following import modules\&.
.PP
\fBalsa\fR \fI[audio]\fR
.RS 4
This module reads audio samples from an ALSA device using libalsa\&.
.sp
This module accepts the following options:
.PP
device (string)
.RS 4
selects ALSA device to use for capturing audio\&.
.RE
.RE
.PP
\fBbktr\fR \fI[video]\fR
.RS 4
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\&.
.sp
This module accepts the following options:
.PP
tunerdev (string)
.RS 4
help: selects tuner device\&.
.RE
.PP
vsource (string)
.RS 4
selects video source (device dependant input)\&.
.RE

.PP
\fBdvd\fR \fI[video, audio, extra]\fR
.RS 4
This module provides access to DVD content using libdvdread, directly from DVD device\&. (e\&.g\&. on\-the\-fly operation, no intermediate disk storage needed)\&.
.sp
At run time, this module requires: libdvdread >= 0\&.9\&.3
.sp
This module accepts the following options:
.PP
delay (integer)
.RS 4
set device access delay (seconds)\&.
.RE
.RE
.PP
\fBim\fR \fI[video]\fR
.RS 4
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\&.
.sp
At run time, this module requires: libMagick >= 6\&.2\&.4\&.0
.sp
This module accepts the following options:
.PP
noseq (flag)
.RS 4
disable internal auto loading of images with similar names\&.
.RE

.PP
\fBpv3\fR \fI[video, audio]\fR
.RS 4
This module provides access to Earth Soft PV3 audio/video streams using win32 binary codecs and an internal win32 emulation layer (NO wine needed)\&.
.sp
At run time, this module requires: PV3 win32 dlls\&.
.sp
This module accepts the following options:
.PP
dllpath (string)
.RS 4
set path/filename to load dv\&.dll from
.RE

\fBvag\fR \fI[audio]\fR
.RS 4
This module decodes VAG\-format audio (from PlayStation)\&.
.sp
This module accepts the following options:
.PP
blocksize (integer)
.RS 4
stereo blocking size\&.
.RE
.RE
.PP
\fBvob\fR \fI[video, audio]\fR
.RS 4
This module imports audio/video from VOB files\&. If you need direct DVD access, use import_dvd module\&.
.sp
This module accepts the following options:
.PP
nodemux (flag)
.RS 4
skip demuxing processing stage\&. This sometimes improves A/V sync\&.
.RE
.RE
.PP
\fBx11\fR \fI[video]\fR
.RS 4
This module captures video frames from X window system using libX11\&.
.sp
At run time, this module requires: libcx11\-6 >= 1\&.0\&.0
.sp
This module accepts the following options:
.PP
skew_limit (integer)
.RS 4
maximum frame A/V skew (ms) before correction attempt
.RE
.RE
.PP
\fBv4l2\fR \fI[video, audio]\fR
.RS 4
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\&.
.sp
This module accepts the following options:
.PP
overrun_guard (integer)
.RS 4
flag (default off)\&. Toggles the buffer overrun guard, that prevents crash when capture buffers are full\&.

.RE
.PP
resync_interval (integer)
.RS 4
checks the resync_margin every given amount of frames\&.
.RE
.PP
format (integer)
.RS 4
forces video frames convertion by using index; use \-1 to get a list of supported conversions\&.
.RE
.PP
format (string)
.RS 4
forces output format to given one; use "list" to get a list of supported formats\&.
