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

The latest development version of SDL is available via Subversion. Subversion allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use svn to mirror that source tree instead of waiting for an official release. Please look at the Subversion website ( http://subversion.tigris.org/ ) for more information on using svn, where you can also download software for MacOS, Windows, and Unix systems. svn checkout http://svn.libsdl.org/trunk/SDL If you are building SDL with an IDE, you will need to copy the file include/SDL_config.h.default to include/SDL_config.h before building. If you are building SDL via configure, you will need to run autogen.sh before running configure. There is a web interface to the subversion repository at: http://www.libsdl.org/cgi/viewvc.cgi There is an RSS feed available at that URL, for those that want to track commits in real time.
