It is assumed there are only two planes , but this is not correct for some
formats, such as RGB32.
Probably ok since currently all decoder output is NV12/P010, but would be
better add an assert check,
since it is possible for decoder to output some other formats (e.g: it is plan
to add RGB format for JPEG decoding output).
