Previously, video playback did not allow for sound. You had to separate the sound into its own file and trigger it on its own. However, according to the Release Notes for 1.20 that has been changed. Here is a cut and paste from the Release doc,
“Input Streaming Support – You can now stream data from a variety of input sources for playback by the audio system. For example, you can play back the audio stream from a video file.”
Unfortunately, there is no other information that I can find. Does anyone know what that means and how to go about using it or getting more information on its implementation?
