     * reworked screensaver disabling support, most users will need to use
       -heartbeat-cmd due to screensaver authors being unable to design a
       common API
+    * grayscale decoding/encoding with FFmpeg disabled, it slowed down

 For best decoding quality use the same IDCT algorithm for decoding and encoding.
 This may come at a price in accuracy, though.
