Hi, How to extract image frames from NvMOTFrame->NvBufSurfaceParams->NvBufSurfacePlaneParams->? Can you give me reference code?

Can you extract your source which can compile and run in our environments for a further check? or if not possible please check below 2 points: 1 as before mentioned, Did you sync GPU buffer hereby buf_list for CPU access before creating cv Mat buffer? NvBufSurfaceSyncForCpu(NvBufSurface surf, int…

For accessing frame buffer, you can refer to this, https://devtalk.nvidia.com/default/topic/1061205/deepstream-sdk/rtsp-camera-access-frame-issue/post/5377678/#5377678 , it’s similar.

I get the following error while using that code mentioned in your link NvMOTStatus NvMOT_Process(NvMOTContextHandle contextHandle,NvMOTProcessParams *pParams,NvMOTTrackedObjBatch *pTrackedObjectsBatch) { NvBufSurfaceParams* buf_list = fr->bufferList[0]; NvBufSurfaceMappedAddr mapd_addr = buf_lis…

Did you sync GPU buffer hereby buf_list for CPU access before creating cv Mat buffer? NvBufSurfaceSyncForCpu(NvBufSurface *surf, int index, int plane)

Previous err was due to pQuery->colorFormats[0] = NVBUF_COLOR_FORMAT_RGBA; in NvMOT_Query, Now I get frames but it is full of stripes I have attached actual and result frame. My code is NvMOTStatus NvMOT_Process(NvMOTContextHandle contextHandle,NvMOTProcessParams *pParams,NvMOTTrackedObjBatch *…

yes, my width is 1280 and pitch is 5120, finally I got the frame :) Thank you.

I am facing the same issue and I am a little puzzled on how to read frame data off of NvBufSurfaceParams**, and how you I can call NvBufSurfaceSyncForCpu with an NvBufSurfaceParams** rather than an NvBufSurface.
