* the best video quality (hardware interpolation when rescaling the picture)
* and the fastest display as it requires less processing.
*
- * If YUV overlay is not supported the plugin will use an RGB offscreen video
- * surface that will be blitted onto the primary surface (display) to
- * effectively display the picture. this fallback method enables us to display
+ * If YUV overlay is not supported this plugin will use RGB offscreen video
+ * surfaces that will be blitted onto the primary surface (display) to
+ * effectively display the pictures. this fallback method enables us to display
* video in window mode.
- * Another fallback method (which isn't implemented yet) would be to use the
- * primary surface as the video buffer. This would allow for better
- * performance but this is restricted to fullscreen video. In short,
- * implementing this is not considered high priority.
+ * Another fallback method (which isn't implemented) would be take the
+ * exclusive control of the screen so we could spare the blitting process and
+ * decode directly to video memory. This should theoretically allow for better
+ * performance (although on my system it is actually slower) but this is
+ * restricted to fullscreen video.
