The FrameQueueBuffer is the interface for buffers used by the FrameQueueSink and the FrameSnapSink. IF you want to implement your own FrameQueueBuffer to queue in FrameQueueSink or FrameSnapSink, you derived from the FrameQueueUserBuffer class.
There are multiple ways to create instances of FrameQueueBuffer:
The buffer lifetimes are managed by reference counting, therefore it is important to always use tFrameQueueBufferPtrs to hold them. The memory will be reclaimed once the last reference is destroyed.
