Added Image input type. Advanced settings panel is used to choose a directory. All images in this directory show up as sources.
Change properties on VTCompressionSession and VTPixelTransferSession to letterbox instead of stretch.
Defer captureSetup until resolution is determined on first frame arrival.
captureFPS no longer bound to videoCaptureSession.videoCaptureFPS. Which means it doesn’t reset when the source is changed.
Fixed an issue with videoCaptureSession deallocation not happening. This means the AVFoundation type will release the camera when it is no longer active.
Added internal API for saving/restoring values. Used for Image capture saving the source directory.
Audio sample rate is now a drop down.
