Remarks
Initially the filter has one input pin, which can accept audio or video input. When that pin is connected, the filter creates a second input pin. If the first input pin receives audio, the second input pin accepts only video, and vice versa.
The filter supports the following properties through ICodecAPI:
- AVAudioChannelCount
