README: updates.

Drop references to deprecated plugins (vaapiupload, vaapidownload),
mention that support for GStreamer 0.10 is deprecated, make overview
more descriptive in certain aspects.

 gstreamer-vaapi consists in a collection of VA-API based plugins for
 GStreamer and helper libraries.
 
-  * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4, H.264, VC-1,
-    WMV3 videos to video/x-vaapi-surfaces surfaces, depending on the
-    underlying HW capabilities.
+  * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4:2, H.264 AVC,
+    H.264 MVC, VP8, VC-1, WMV3 videos to VA surfaces, depending on the
+    underlying hardware capabilities. This plugin is also able to
+    implicitly download the decoded surface to raw YUV buffers.
 
-  * `vaapiencode_<CODEC>' is used to encode into MPEG-2, H.264 videos,
-    depending on the actual value of <CODEC> (mpeg2, h264, etc.). By
-    default, raw format bitstreams are generated, so the result may be
-    piped to an actual muxer like qtmux for MP4 containers.

-  * `vaapiupload' is used to convert from video/x-raw-yuv pixels to
-    video/x-vaapi-surface surfaces.
+  * `vaapipostproc' is used to filter VA surfaces, for e.g. scaling,
+    deinterlacing (bob, motion-adaptive, motion-compensated), noise
+    reduction or sharpening. This plugin is also used to upload raw
+    YUV pixels into VA surfaces.
 
-  * `vaapidownload' is used to convert from video/x-vaapi-surface
-    surfaces to video/x-raw-yuv pixels.
-
-  * `vaapipostproc' is used to postprocess video/x-vaapi-surface
-    surfaces, for e.g. deinterlacing, denoising and sharpening.
-
-  * `vaapisink' is used to display video/x-vaapi-surface surfaces to
-    screen.
+  * `vaapisink' is used to render VA surfaces to an X11 or Wayland
+    display. This plugin also features a "headless" mode (DRM) more
+    suited to remote transcode scenarios, with faster throughput.
