Hi,

I'm working with the SwitcherPanelCSharp example and have a couple "newbie" questions...

1. How can you set the number of frames for the "auto" transition? Apparently, there is a SetRate function, but I'm not finding a way to access it in the SwitcherPanelCSharp example.

2. How can I add volume monitoring and volume control to this app? Is there an example somewhere?

Many thanks!

OK... I've solved the mix duration problem... but still need some audio help.

Here's the mix duration:

double dTransitionFrames = dFramesPerSecond*dTransitionSeconds;

BMDSwitcherAPI.IBMDSwitcherTransitionMixParameters m_params =
(BMDSwitcherAPI.IBMDSwitcherTransitionMixParameters)m_mixEffectBlock1;

m_params.SetRate((uint)dTransitionFrames);


However, I'd still like to display audio levels in my app. How do I get an interface to audio and what function call do I use poll it periodically?

Any help is appreciated.
