I am currently trying to use the VPU on my i.MX6Q Sabre SD board. I read the VPU API document and (as a 1st test) I am using the sample mxc_vpu-test.out available in the /unit_tests folder.


I read in the VPU documentation that the only format available is YUV 4:2:0 so I download from this website ( :: Derf's Test Media Collection) a 720p file in 4:2:0 format.


My command line is the folowing one: ./mxc_vpu_test.out -E "-i input.y4m -w 1280 -h 720 -f 2 -t 0 output.264"


The output is not correct, the color is wierd and the frame is not correct as well.


Please, can you give me any information about what I did wrong or provide me a working test ?
