XCDPLAYER(1)		     General Commands Manual		    XCDPLAYER(1)

NAME
     xcdplayer	- X window system interface to run the sun or sgi cdrom drive as
     a typical audio CD player.

SYNOPSIS
     xcdplayer [ -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 XCDINFODIR.  If no directory
     is specified by any of these methods, xcdplayer looks in the current direc-
     tory.

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  scrollbar
		 shown	(default  .267).  This value is used in conjunction with
		 the volBase parameter.

     -cdInfoDir  Specifies which directory should be used for storing and  look-
		 ing 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  selection	buttons.
			 The program window (and program mode) are dismissed via
			 the Cancel button.

COMMAND BUTTONS
   Main Commands
     play	    Enter play mode.

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

     stop	    Stop disc and reset to beginning.

     prev	    Go	back  either  to the beginning of the previous track (or
		    start of current track if more than replayThreshold  seconds
		    have  elapsed); if in program mode, go to previous selection
		    in program.

     next	    Go to beginning of next track; if in  program  mode,  go  to
		    next program selection.

     eject	    Eject the disc. Resets all modes.

     audio	    Toggle the audio output if possible.  It will default to the
		    best quality audio available (SGI only).

     quit	    Exit xcdplayer.  (Leaves disc in last set state.

     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 con-
		    trolled by the resources scanSkipInterval  and  scanPauseIn-

     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 cur-
			 rently selected track deletes it from the program.  The
			 highlighted  selection  indicates   the   current   in-
			 sert/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 click-
			 ing on the track buttons on the program form, or by us-
			 ing  the  forward and previous buttons on the main form
			 while paused, and  then  clicking  the  program  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 when-
			 ever the current disc is put into the player.

     track buttons	 Add the track number to the program at the current  in-
			 sertion  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 ti-
			 tles won't distort the size of the tool.

FILES
     cdInfoDir/cd.* these files contain title and stored program info saved  for
     CDs

SEE ALSO
     X(1)

LIMITATIONS
     Xcdplayer	cannot	yet  read the current volume level and adjust the volume
     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.
