This adds support for frame-skip-mode standard v4l2 control in encoder driver. The control is implemented based on the combination of client selected bitrate-mode and frame-skip-mode. Once The client selected bitrate-mode (constant or variable) and the frame-skip-mode is not disabled we set variable framerate for rate controller.
