Adam Strzelecki to SDL
When graphic card has no GL_ARB_texture_rectangle YUV textures mapped with SDL_RenderCopy are stretched 2x horizontally, so only left half of texture is visible. This is due:
data->texw = (GLfloat) (texture->w) / texture_w;
data->texh = (GLfloat) texture->h / texture_h;
But afterwards texture_w /= 2 for YUV texture, but data->texw stays as it was before, while it should be multiplied 2x.
This bug can be seen in any program setting env variables: GL_APPLE_ycbcr_422=0 GL_EXT_texture_rectangle=0 GL_ARB_texture_rectangle=0

SDL 1.3 with open pandora console support ( http://openpandora.org/ ) ===================================================================== - A pandora specific video driver was writed to allow SDL 1.3 with OpenGL ES support to work on the pandora under the framebuffer. This driver do not have input support for now, so if you use it you will have to add your own control code. The video driver name is "pandora" so if you have problem running it from the framebuffer, try to set the following variable before starting your application : "export SDL_VIDEODRIVER=pandora" - OpenGL ES support was added to the x11 driver, so it's working like the normal x11 driver one with OpenGLX support, with SDL input event's etc..
