With the patch kept:
v4l2-ctl --verbose
--set-fmt-video-out=width=1280,height=720,pixelformat=NV12
--set-selection-output target=crop,top=0,left=0,width=1280,height=720

With the patch reverted:
v4l2-ctl --verbose
--set-fmt-video-out=width=1280,height=720,pixelformat=NV12
--set-selection-output target=crop,top=0,left=0,width=1280,height=720

--stream-from=cyclists_1280x720_92frames.yuv
--stream-to=/tmp/cyclists_1280x720_92frames.h264 -d /dev/video1
VIDIOC_QUERYCAP: ok
VIDIOC_G_FMT: ok
The pixelformat 'H264' is invalid
VIDIOC_G_FMT: ok
The pixelformat 'NV12' is invalid

Decoding breaks if I revert the patch as well, it fails with a power
collapse fail.
