Hi, all

    I according to "Application Parameter Settings for DM365 H.264 Encoder" document to setting setting mvSADoutFlag = 1. Then I get CMEM ERROR, follow is my parameter setting and error information:

   Parameter setting:

....

      h264Params.entropyMode = 1;
       h264Params.transform8x8FlagIntraFrame = 1;
       h264Params.transform8x8FlagInterFrame = 0;
      h264Params.unrestrictedMV = 1;
       h264Params.seqScalingFlag = 1;

....

      h264DynParams.rcAlgo = 0;
      h264DynParams.initQ = -1;
      h264DynParams.rcQMax = 44;
      h264DynParams.rcQMin = 8;
      h264DynParams.maxDelay = 500;
      h264DynParams.perceptualRC = 1;
      h264DynParams.mvSADoutFlag = 1;
      h264DynParams.meMultiPart = 0;

    Hi,

    When mvSADoutFlag is enabled, one needs to supply an extra buffer as part of outBufs so that codec can dump the motion vector and SAD values. Please see http://processors.wiki.ti.com/index.php/Using_MV_SAD_Info_of_DM365_encoder_in_Application for more details.

    regards

    Yashwant
