Access to macroblock Quantizer-Parameter (QP) when decoding H.264

I’m working on H264 video quality and need to know QP of macroblock (min , max , avg … ) is it possible to have such information (maybe throught HandlePictureDecode(void *pUserData, CUVIDPICPARAMS *pPicParams) => pPicParams->CodecSpecific.h264 …) . or is the NVDecode SDK API only at the frame level?


In the shipping SDKs, the APIs support decoding only. We don’t have any mechanism which can dump out macroblock level information. We are curious to know, why exactly you want this information? Please shed more light on your use-case and what you are planning to do with the QP values.
