       xjadeo - the X Jack Video Monitor

       Xjadeo is a software video player that displays a video clip synchronized
       to an external time source (MTC, LTC, JACK transport).

       Xjadeo is intended for soundtrack composition, video monitoring and
       useful for any task that requires to synchronizing movie frames with
       audio events.

       -A, --avverbose
              Display verbose video decoder messages.

       -a, --ontop
              Keep xjadeo window on top of other applications.

       -b, --no-letterbox
              Scale movie to fit window. Without this option a letterbox is used
              to retain the aspect ratio.

       -D, --debug
              Print development related information.

       -d <name>, --midi-driver <name>
              Specify midi driver to use. Run 'xjadeo -V' to list supported
              driver(s). <name> is case insensitive and can be shortened to the
              first unique name.  eg '-d j' for jack, '-d alsa-r' for alsa-raw

       -f <val>, --screen-fps <val>
              Desired refresh rate of the video display in frames If this value
              is equal or less than zero, xjadeo will use the FPS of the video
              file as its update frequency (which is the default).  Note: This
              does not affect screen/vblank sync.  Synchronizing to the screen's
              vertical refresh is hardware dependent (and always used if

       -h, --help
              Display this help and exit.

       -I, --ignore-file-offset
              This option is only useful for video files with a start offset,
              such as split vob files.  Per default xjadeo honors offsets
              specified in the video file header. This option allows one to
              override (and subtract) this offset to align the start of the file
              with timecode 00:00:00:00.

       -i <int>, --info <int>
              Display time information using the OSD (on screen display).
              0:Off, 1: Frame number, 2: Timecode, 3: both.

       -J, --no-initial-sync
              Do not connect to JACK, nor use any other sync source at
              application start.

       -K <int>, --keyframe-limit <int>
              Specify a maximum key-frame interval limit.  With most video
              codecs, a video frame is the sum of a key-frame plus differences
              from the closest key-frame.  For non continuous playback and
              random seeks xjadeo will have to go back to a key-frame and decode
              sequentially to the target frame.  This can be quite CPU intense
              and hence the max.  sequential decoding sequence is limited. By
              default to 100 frames For fast frame accurate seeks, it is highly
              recommended to transcode the video file using a codec where every
              frame is a key-frame (eg. mjpeg), and the video consists only of
              "intra" frames.  (the key-frame interval is sometimes also called
              "group of pictures"s or GOP).

       -l, --ltc
              Sync to Linear Time Code (audio jack).

       -M <int>, --midifps <int>
              Specify MTC conversion mode:

       0:     use frame-rate from MTC clock (default)

       1:     use video file's fps

       2:     "resample" file's fps / MTC

       -m <port>, --midi <port>
              Use MTC as sync source The <port> argument is midi driver

              specify a midi port name to connect to,

       or "" to not auto connect.
              alsa-seq:  specify ID to connect to (-1: none)

       eg. -m ardour or -m 80
              alsa-raw:  specify hardware device

       eg. -m hw:1,0 or -m 1
              portmidi:  numeric id; -1: autodetect

       a value > -1 specifies the port number to use.
              use '-v -m -1' to list midi ports.

       -O <port>, --osc <port>
              Listen for OSC messages on the given port.  Xjadeo can be remote
              controlled using Open Sound Control. For a list of available
              commands, please see the source code or online documentation.

       -o <val>, --offset <val>
              Time offset video from timecode source. This allows one to offset
              the video playback a certain number of (video) frames relative to
              the time source.  Positive and negative values are permitted.  The
              offset van be specified either as integer frame number of as colon
              separated timecode.

              Print available OSC commands and exit.

       -Q, --mq
              Enable POSIX realtime message queues.  This sets up a
              communication channel for remote, intended to be used with

       -q, --quiet, --silent
              inhibit usual output.

       -R, --remote
              Enable interactive remote control mode using standard I/O. This
              option implies non-verbose and quiet as the terminal is used for

       -r <file>, --rc <file>
              Specify a custom configuration file to load.

       -S, --no-splash
              Skip the on screen display startup sequence.

       -s, --fullscreen
              Start xjadeo in full screen mode.

       -T <file>, --ttf-file <file>
              path to .ttf font for on screen display

       -U, --uuid
              specify JACK SESSION UUID.

       -V, --version
              Print version information and exit.

       -W <rpc-id>, --ipc <rpc-id>
              Setup IPC message queues for remote control Inter Process
              Communication is used by `xjremote` on OSX and other platforms
              that do not support realtime message queues

       -v, --verbose
              print more information

       -x <int>, --vo <int>, --videomode <int>
              Select a video output mode (default: 0: autodetect) A value of -1
              lists the available mode and exits

Synchronization Sources:
       JACK:  JACK transport

       LTC:   Linear/Longitudinal Time Code - via JACK audio

       MTC:   MIDI Time Code via JACK MIDI

       MTC:   MIDI Time Code via ALSA sequencer (Linux only)

       MTC:   MIDI Time Code via ALSA raw devices (Linux only)

       MTC:   MIDI Time Code via portmidi (OSX, Windows)

              Remote controlled manual seeks.

       If neither -m nor -l options are given, xjadeo synchronizes to jack
       transport by default.

Video Codecs and Formats:
       Xjadeo uses ffmpeg to decode video files, so a wide range of formats and
       codecs are supported. Note however that not all the codecs support
       reliable seeking.  It is highly recommended to transcode the video file
       into a suitable format/codec. The recommend combination is avi/mjpeg.
       e.g. ffmpeg -i input-file.xxx -an -vcodec mjpeg output-file.avi This
       creates from your input-file.xxx an AVI mjpeg encoded video file without
       sound, and no compression between frames (motion jpeg - every frame is a
       key-frame). You may want also to shrink the size of the file by scaling
       down its geometry. This uses fewer system resources for decoding and
       display and leaves more space on the screen for your audio software.  see
       ffmpeg -s <width>x<height> option and read up on the ffmpeg man page for
       further options. e.g. -qscale 0 to retain image quality.

Configuration Files:
       At startup xjadeo reads the following resource configuration files in the
       following order:

       system wide:
              /etc/xjadeorc or /usr/local/etc/xjadeorc

       old user config:

       user config:
              $XDM_CONFIG_HOME/xjadeo/xjadeorc (usually $HOME/.config/)

       on OSX:

       on Windows:

       and $HOMEDRIVE$HOMEPATH\Local Settings\xjadeorc
              (usually C:\Documents and Settings\<Username>\)

       project specific:

       Every line in the configuration file is a KEY=VALUE pair. If the first
       character on a line is either is a literal '#' or ';', the line is
       ignored.  KEYS are case insensitive. Boolean values are specified as
       'yes' or 'no'.  As for a list of available keys, please see the example
       configuration file, which is available in the documentation folder of the
       source code.

       If xjadeo is compiled with jack session support, it will save its current
       state as config file and pass it as handle to the jack session manager.

User Interaction:
       The xjadeo window offers a right-click context menu (except on OSX where
       the application has a main menu bar) which provides easy access to common
       functionality.  On OSX and Windows this menu offers a file open dialog to
       change the video file that is being monitored. On Linux new files can be
       loaded by dragging the file onto the window itself.  In addition xjadeo
       reacts to key presses. The following shortcuts are defined:

       'Esc'  Close window and quit

       'a'    Toggle always-on-top mode

       'b'    Toggle On Screen Display black border

              XV color balance is hardware dependent.

       Note that it is possible to disable certain features using the remote
       control.  A Host can take control of certain aspects e.g. offset or
       disallow closing the video monitor, except by host-provided means.
