Simplify the stream API. make just 2 methods to queue and dequeue buffers. Make just one callback when new buffers can be dequeued. Add support for driver nodes such as the video-src. Pass a pw_buffer structure to add/remove_buffer and make it possible to attach metadata to it. This makes it a lot easier to implement the gstreamer pipewire pool. Call the stream process function from the main loop and use a lockfree ringbuffer to pass buffers between the threads. Make it possible to also call process from the RT thread. unmap the buffer data when needed.
