XCDPLAYER(1)XCDPLAYER(1)NAMExcdplayer - X window system interface to run the sun or sgi cdrom drive
as a typical audio CD player.
SYNOPSISxcdplayer [ -toolkitoption ... ] [-xcdplayeroption ... ]
DESCRIPTION
Xcdplayer is a graphical user interface for controlling the Sun or SGI
cdrom drive under the X Window System. It provides visual feedback and
gives the user facilities for mode selection, device control, scanning,
and programming.
Xcdplayer allows previously stored cd title and program information to
be read from a specified directory and loaded into the player on
startup or at disc changes. This directory can be specified either on
the command line, by using the -cdInfoDir option, by using a customized
personal resource file, or by setting the environment variable XCDIN‐
FODIR. If no directory is specified by any of these methods, xcdplayer
looks in the current directory.
OPTIONS
Xcdplayer accepts all of the standard X Toolkit command line options
(see X(1)), plus the following xcdplayer specific options:
-debug Displays debugging messages as the tool runs.
-device CDROM device to use (useful for systems with multiple CDROM
drives)
-volBase Bottom of volume scale for player [range 0-255] (default
187)
-volPcent Ratio of volume change [range 0..255] to percent of scroll‐
bar shown (default .267). This value is used in conjunc‐
tion with the volBase parameter.
-cdInfoDir Specifies which directory should be used for storing and
looking up CD information.
SUBWINDOWS
Xcdplayer contains the following subwindows:
Title Window Displays the title of the CD (if stored or entered)
corresponding to the CD currently in the CD player.
Program Window Brought up on press of the program button, this
panel contains a viewport displaying the current
selected program, option buttons, and track selec‐
tion buttons. The program window (and program
mode) are dismissed via the Cancel button.
COMMAND BUTTONS
Main Commands

pause Pause play. Activating this button has an effect on
program selection.

(or start of current track if more than replayThreshold

ous selection in program.

cycle Cycle the disc. If in shuffle mode, reshuffle will
occur at end of current shuffle; if in program mode, the
program will replay.
shuffle Select all of the tracks in random order. This button
has no effect unless play mode is not active, and is a
toggle to program mode.
rewind Rewind the disc. If held down, will continue rewinding.
Scan skip amount and pause interval between skips are
controlled by the resources scanSkipInterval and scan‐
PauseInterval. If the disc is paused, it will skip by
the ammount specifed by pauseSkipInterval.

program Enter program mode. If paused, add current track (if
not 0) to program. Brings up program subwindow.
Program Commands
Selections Selections displayed in the viewport of the program
subwindow can be clicked on, and clicking on the
currently selected track deletes it from the pro‐
gram. The highlighted selection indicates the cur‐
rent insert/delete point in the program, and if the
CD is paused, clicking on a selection moves the
program play point to that selection.
Selections can be added to the program either by
clicking on the track buttons on the program form,
or by using the forward and previous buttons on the
main form while paused, and then clicking the pro‐
gram button again. Pre-insertion before the 1st
programmed track is allowed by clicking on the
space preceding the 1st entry.
Clear Clears current program.
Cancel Clears current program and cancels program mode and
subwindow.
Save Save the current program (if any) and current title
to file in cdInfoDir. This file will then be read
whenever the current disc is put into the player.
track buttons Add the track number to the program at the current
insertion point, or if active, add track number to
the programmable track button.
+10 Add ten to the programmable track button.
programmable track Add the selected track number (if available on CD)
to program at the current insertion point.
All Replace the current program with a sequential list
of tracks on the CD.
Miscellaneous Commands
track Show number of tracks on the CD.
timer Toggle between time elaped and time remaining. If
in program mode, and not paused, toggles to time
remaining in program.
volume scroll Adjust volume of CD player output.
title Pop up dialog for editing title display. Title can
then be associated permanently with that CD by
using the save button in the program subwindow.
The title is displayed on a button in a viewport,
so that long titles won't distort the size of the
tool.
FILES
cdInfoDir/cd.* these files contain title and stored program info saved
for CDs
SEE ALSOX(1)LIMITATIONS
Xcdplayer cannot yet read the current volume level and adjust the vol‐
ume scroll accordingly, because there is not current support for this
in the driver.
BUGS
Xcdplayer occasionally "hangs" on a particular track, never quite
reaching the end of it. Advancing to the next or previous track, or
pressing the stop button rectifies this condition.
