hi, all:
After I compiled the V4L2 sources and the sample driver for it in
the
webpage of the V4L2 http://www.thedirks.org/v4l2/, and run the Sample
applications (xcaptest, vidpanel, vcat, vctrl). only the vidpanel can run,
and
when I click the video button , it will exit with error. and other
applications
with this informations:
QUERYCAP in construct_v412_buffer: Invalid argument.
what 's this mean and what should I do. I know there may be some path error
in the compiling of the sample capture driver, but i don't know how to
modify
it.
Regards,
zhang zhijun
