Hi community members, I use libvpu.so to decode a polluted JPEG picture time to time, then I check the value of DecOutputInfo.numOfErrMBs in /external/fsl_imx_omx/OpenMAXIL/src/component/vpu_wrapper/vpu_wrapper.c, the results are unstable, sometimes the value is an stable integer greater than zero and sometimes is zero. I did another experiment, If I try a unpolluted picture, the result is always zero. So is the field DecOutputInfo.numOfErrMBs really work for JPEG decoding? Thanks!
what board do you use?mx53 or mx6? how did you decode jpeg? using unit test?
I use mx6q, I didn't use the unit test, I used the API in vpu_wrapper.h to decode the picture, I get a correct decoded picture, and the API didn't report any error.
