Image, Audio, and Video Extenders Administration and Programming


How environment variables are used to identify display or play programs

In addition to resolving file names, environment variables are also used to identify programs to display image objects retrieved by the Image Extender and play audio or video objects retrieved by the Audio and Video Extender. You use the DBiBrowse, DBaPlay, and DBvPlay APIs, respectively to display or play these objects. When you use each API, you can specify a display or play program or you can indicate that you want a default program to display or play the object.

The DB2 Extenders use the following environment variables in the client to identify the default display or play programs:
Environment variable Description
DB2IMAGEBROWSER Used to identify the default image display program.
DB2AUDIOPLAYER Used to identify the default audio player program.
DB2VIDEOPLAYER Used to identify the default video player program.
