Make a new USE_BUFFERS command to atomically send a buffer array to the remote client. We can use this to then clean up an old array and go to the PAUSED state if possible. Work on formats. Make one structure that can hold all video formats. Work on pipeline suspend and resume. Add jpeg support to v4l2. Work on enum_formats with a filter in v4l2.
