Mason Wheeler to sdl I updated SDL, and suddenly my SDL frames stopped working. They'd "initialize" full of gibberish, and I couldn't render anything to them. After a bit of digging, I found a problem: the renderer initialization routine in my SDL frame code wasn't getting called anymore. procedure TSdlFrame.Paint; begin if SDL_SelectRenderer(FWindowID) = -1 then CreateRenderer; SDL_RenderPresent; end; function TSdlFrame.CreateRenderer: boolean; const pf: tagPIXELFORMATDESCRIPTOR = (nSize: sizeof(pf); nVersion: 1; dwFlags: PFD_DRAW_TO_WINDOW or PFD_SUPPORT_OPENGL or PFD_DOUBLEBUFFER; iPixelType: PFD_TYPE_RGBA; cColorBits: 24; cAlphaBits: 8; iLayerType: PFD_MAIN_PLANE); RENDERERS: array[TRendererType] of AnsiString = ('software', 'gdi', 'opengl', 'd3d'); var pFormat: integer; begin if (SDL_SelectRenderer(FWindowID) = 0) then begin result := true; Exit; end; if FRendererType = rtOpenGL then begin pFormat := ChoosePixelFormat(canvas.Handle, @pf); if not SetPixelFormat(canvas.Handle, pFormat, @pf) then outputDebugString(PChar(SysErrorMessage(GetLastError))); if wglCreateContext(canvas.Handle) = 0 then outputDebugString(PChar(SysErrorMessage(GetLastError))); end; if (SDL_CreateRenderer(FWindowID, SDL_RendererIndex(RENDERERS[FRendererType]), [sdlrPresentFlip3, sdlrAccelerated]) = 0) then begin SDL_ShowWindow(FWindowID); assert(SDL_SetRenderDrawColor(0, 0, 0, 255) = 0); FFlags := SDL_GetWindowFlags(FWindowID); if assigned(FOnAvailable) then FOnAvailable(self); end else outputDebugString(pChar(format('SDL_CreateRenderer failed: %s', [sdl_GetError]))); result := SDL_SelectRenderer(FWindowID) = 0; end; This is a critical issue. The Paint method gets called when the control receives a WM_PAINT message from Windows. I can't create the renderer before then, or it will fail and cause trouble. And when I do create it, it needs to be created with certain parameters. So imagine my surprise when I started debugging into the DLL and found that SDL_SelectRenderer was trying to be "helpful" by creating the renderer for me if it didn't already exist! Now not only does my initialization code not get called, I end up with the wrong renderer and so things don't render as expected when I try to use the window.

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'll than need to install the SPU-libs
  - Run make ps3-libs && make ps3libs-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 support
  - On SPU-side the current scaler and converter restrictions are:
    - resolution has to be a multiple of 8 (will work on that)
    - scaler/converter only supports the YV12 and IYUV format
    - the scaler works only bilinear (lanzos would be nice)
  - Optimize the SPU-program handling on the PPE side
  - Integrate spumedia in SDL

Have fun!
