+// 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.
