A call to video.Stop is needed before changing the audio output when a video file is playing or has played.
Example: This example shows how to use the SetPcmAudioOutputs and SetCompressedAudioOutputs methods in
conjunction with roAudioOutput . The video player is configured to output decoded audio to the analog output or
compressed audio to the HDMI and SPDIF outputs.
ao1=CreateObject("roAudioOutput", "Analog")
ao2=CreateObject("roAudioOutput", "HDMI")
ao3=CreateObject("roAudioOutput", "SPDIF")
v1=CreateObject("roVideoPlayer")
v1.SetPcmAudioOutputs(ao1)
--or--
ar = CreateObject("roArray", 2, true)
ar[0] = ao2
ar[1] = ao3
v1.SetCompressedAudioOutputs(ar)
Note: In most cases, rerouting audio outputs during audio/video playback will cause playback to stop. The system
software will still be responsive, so you can use commands to exit playback during or following an audio output
modification.
