Launching external programs from the cue list
Use the execute file command in the cue list to launch external programs. External programs could in
principle be anything, for example digital video viewers, but will most likely be a custom made
program for specific requirements.
The program may be launched with a number of parameters such as a filename or special command
switches. Parameters are entered in the column normally used for comments, so when using the
execute command it is NOT possible to use comments on that particular line. Since LightJockey
doesn't know anything about the external programs, what they do or how they behave, there are a
couple of considerations to consider when launching external programs.
The program must be able to take all settings and commands through the parameters (or by saving
specific setups that are automatically recalled when the program is launched). It is not possible to
communicate with the program from LightJockey.If the program is repeatedly launched (for example
by a looping cuelist), the program must be able to handle this by not launching a second instance if it
is already running. If the program is re-launched in a new instance, it will eventually suffocate the PC
when too many instances are running. The entire path for the executable including the name of the
executable cannot exceed 127 characters. The total length of the parameters cannot exceed 40
characters.
Using the LightJockey MediaPlayer
LightJockey Mediaplayer
The LightJockey Mediaplayer is a separate application which utilizes Windows Media Player (tm) to
play a multitude of digital media files including digital audio (MP3, WMA etc) or digital video (MPG,
AVI, etc) files - note that the LightJockey Mediaplayer will not play any other formats not supported by
the installed Windows Media Player (see below). Note that Since the application uses Windows
Media Player functions it must be installed on the PC for the LightJockey Mediaplayer to work. At the
time of writing, the newest version of the Windows Media Player can be downloaded from http://www.
microsoft.com/windows/windowsmedia/download. The LightJockey Mediaplayer is used from the
cuelist where it can be programmed to play back media files and send back time code to the cue list
for synchronization between media file and lights.
Media File Formats
Since the LightJockey Mediaplayer uses the functions of Windows Media Player it is capable of
playing all media file formats that the Windows Media Player can with the exception of CD audio. For
playback of audio CDs use the built in Audio CD player.
There are however a number of pitfalls when using digital media files. First of all, Windows Media
Player may not directly support specific encoding formats (Codecs) - although sometimes a solution
