A skipped frame is detected when the producer offers a frame while the current pending frame has not been consumed. However, the producer (in practice the decoder) is not interested in the fact that a frame has been skipped, only the consumer (the renderer) is. Therefore, notify frame skip via a consumer callback. This allows to manage the skipped and rendered frames count at the same place, and remove fps_counter from decoder.
