Notes

-* There are two renderers: native gxm and pigs-in-a-blanket gles2.

  • By default gxm one is used. gles2 renderer is slow and only usable if you want to bind SDL_Texture to GL context.
  • You can create gles2 renderer by using hint or 1 as a renderer index in SDL_CreateRenderer.
    +* gles2 support is disabled by default and can be enabled by configuring with -DVIDEO_VITA_PIB=ON
  • By default SDL emits mouse events for touch events on every touchscreen.
    Vita has two touchscreens, so it’s recommended to use SDL_SetHint(SDL_HINT_TOUCH_MOUSE_EVENTS, "0"); and handle touch events instead.
  • Support for L2/R2/R3/R3 buttons, haptic feedback and gamepad led only available on PSTV, or when using external ds4 gamepad on vita.
