// This hack does two things:
// -- it sets preview to NV21 (YUV420SP)
// -- it sets gralloc to YV12
//
// The reason being: the samsung encoder understands only yuv420sp, and gralloc
// does yv12 and rgb565. So what we do is we break up the interleaved UV in
// separate V and U planes, which makes preview look good, and enabled the
// encoder as well.
//
// FIXME: Samsung needs to enable support for proper yv12 coming out of the
// camera, and to fix their video encoder to work with yv12.
// FIXME: It also seems like either Samsung's YUV420SP (NV21) or img's YV12 has
// the color planes switched. We need to figure which side is doing it
// wrong and have the respective party fix it.
