fluster score is still 77/147 so no regressions.
NV12_4L4 is the first pixel format enumerated by the driver so it is the one used
by fluster pipeline and it is well converted into I420 by GStreamer's videoconvert.
Do not worry NV12 is also working fine :-)
I have tested Beauty, Jockey and ShakeNDry from UVG set and I see no problems.
