Hello.

This patch provides basic support for video on the Sony PS3 Linux framebuffer. Scaling, format-conversion, and drawing is done from the SPEs, so there is little performance impact to PPE applications. This is by no means production quality code, but it is a very good start and a good example of how to use the PS3's hardware capabilities to accelerate video playback on the box. The driver has been verified to work with ffplay, mplayer and xine. This piece of software has been developed at the IBM R&D Lab in Boeblingen, Germany and is now returned to the community. Enjoy !

+SDL on Sony Playstation3
+------------------------
+
+Installation:
+  First, you have to install the Cell SDK
+  - Download the Cell SDK installer RPM and ISO images to
+    a temporary directory such as /tmp/cellsdk.
+  - Mount the image: mount -o loop CellSDK-Devel-Fedora_3.1.0.0.0.iso /tmp/cellsdk
+  - Install the SDK installer: rpm -ivh cell-install-3.1.0-0.0.noarch.rpm
+  - Install the SDK: cd /opt/cell && ./cellsdk --iso /tmp/cellsdkiso install
+
+  You need to install the SPU-libs before installing SDL
+  - Go to SDL-1.2/src/video/ps3/spulibs/
+  - Run make && make install
+
+  Finally, install SDL
+  - Go to SDL-1.2/ and build SDL like any other GNU style package.
+  e.g.
+    - Build the configure-script with ./autogen.sh
+    - Configure SDL for your needs: ./configure --enable-video-ps3 ...
+    - Build and install it: make && make install
+
+
+Todo:
+  - mouse/keyboard/controller support
+
+Have fun!
