User's Guide

If a directory name is specified as a command-line argument, the jukebox scans that directory at start-up. Otherwise, it scans the default SDK media directory, which is located at Multimedia\Media under the SDK root directory. The jukebox displays a list of all the media files in the directory, from which the user can select a file to play. To can scan a different directory, type the path name into the edit box and click the Set Media Directory button.

The jukebox offers the following user-interface elements:

• Play, Stop, Pause, and FrameStep buttons: Use these buttons to control graph playback. (The FrameStep button might be disabled, if the graph does not support IVideoFrameStep.)
• Thru and Loop buttons: Click the Thru button to play through the entire file list, starting from the current selection. Click the Loop button to loop the same file repeatedly. These two buttons are mutually exclusive.
• Mute button: Mutes the audio.
• Filters, Input Pins, and Output Pins: When the jukebox creates a graph, it displays a list of the filters in the graph. If the user selects one of the filter names, the jukebox displays a list of the filter's input pins and a list of the filter's output pins.
• Display Events: If this box is checked, the jukebox displays the event codes that it receives. To clear the list, click the Clear button.
• Filter Properties button: To view a filter's property pages, select the filter name and click the this button. If the filter does not support property pages, the button is disabled.
