Hi all,
I was looking around in the v4l2apps directory and played a little bit
with the tools.
I ran driver-test and saw an error:
QUERYBUF: ERROR: VIDIOC_S_FMT said buffer should have 460800 size, but
received 462848 from QUERYBUF!
Can somebody explain please what this means and if it needs to be fixed?
Regards,
Wouter
