The G1 *hardware* supports only semi-planar formats. Those are not supported by the emulator, in effect any other YUV format is not supported on h/w or emulator. The semi-planar planes are not displayed using opengl (see surfaceflinger's code). semi-planar formats have a plane Y followed by a plane of CbCr (packed).
