This release of the OS/2 Multimedia Application Programming Guide includes the following:
An OS/2 application that does not have a PM window, and therefore cannot use a PM message queue for receiving notification messages, can use an OS/2 Control Program queue instead. The Control Program queue method of notification should also be considered for time-critical PM applications, because it is faster than using the PM message queue.
The DART interface enables games and multimedia applications to bypass the waveaudio device entirely and communicate directly with the amp mixer.
DIVE transparent blitting functions enable an interactive game or imaging application to create composites of graphics and image data using a transparency key color. See Transparent Blitting for more information.
Additional MCI_CUE flags allow digital video devices to seek to a specified position and to display or hide the video window when cueing the media. See Playing Motion Video Files for more information.
