Hi,

 

I think it's a basic question. When I executed /unit-test/JPEG/encoder_test.out follow usage, I got a error.

Could you please explain what I have a wrong?

 

1. The way that I executed it and there isn't a command for IOCTL.

root@var-som-mx6:/unit_tests/JPEG# ./encoder_test.out -d /dev/mxc_vpu -f outfile.rgb

mxc_vpu 2040000.vpu_fsl: No such IOCTL, cmd is -2140645888
FILE SIZE 786432
VIDIOC_QUERYCAP: Invalid argument

 

Best regards,
