Hello,

I need to programatically (useing some schedule) to alter live audio/video stream

Stream is transcoded into several presets.

I managed to add/remove overlay as needed, but have no idea how to mute/unmute audio.

Is there any way todo this programatically?

Hi,

One method of doing this is to load a different transcoder template for your streams programmatically using the Transcoder Java API. The new template would have audio track enabled/disabled. You would need to implement the ILiveStreamTranscoderControl interface to load the new template.
