topic Is the field DecOutputInfo.numOfErrMBs in VPU API really work for JPEG decoding? in i.MX Processors https://community.nxp.com/t5/i-MX-Processors/Is-the-field-DecOutputInfo-numOfErrMBs-in-VPU-API-really-work/m-p/326814#M43939 <HTML><HEAD></HEAD><BODY><P><SPAN style="color: #3d3d3d; font-family: 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;">Hi community members, </SPAN>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&nbsp; 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?
