For DirectShow, I see I can query the audio with the IBasicAudio interface and have control of the audio mute. However I am not seeing similar feature for video. So the question is, is there one? Or should I look at another solution, such as stopping and running the filter again. How is change channel typically done in DirectShow? Many thanks.

Permalink. I appreciate your response, but disconnecting the filter is not an option. The goal is not just to stop the audio, or I would use IBasicAudio. If my. player mutes the audio, I want it to match the task bar volume control. That. is, you should be able to mute from the player and unmute from task bar, and. visa-versa.
