Comments

The capture object's settings can be saved to a file by calling IltmmCapture::SaveSettingsToFile.

Saved settings can be loaded using IltmmCapture::LoadSettingsFromFile or IltmmCapture::LoadSettingsFromStream.

It may be helpful to call IltmmCapture::CanSaveObjectSettings before calling either IltmmCapture::SaveSettingsToFile or IltmmCapture::SaveSettingsToStream, to make sure the settings you want to save can be saved. If either IltmmCapture::SaveSettingsToFile or IltmmCapture::SaveSettingsToStream is called for settings that cannot be saved, the save function will fail.
