Visual Basic Call
PSJ6HW,QLW2SHQORQJYDO
Remarks
When the argument val is set to 1, then upon loading of an MPEG,
the video output goes black, buffers are all flushed, and channels
requiring cross channel synchronization will start up “tighter.”
When the argument val is set to 0, then upon loading of an MPEG,
there is a seamless transition to new files but no output reset is
available. However, sometime with this setting, a “rolling” or
“flickering” in some monitors is eliminated.
Testing should be done with both settings to determine the desired
presentation results.
mpgPlay
The mpgPlay function starts or resumes playback on a channel.
