Hey, I didn’t get, could you provide more details about what you are trying to do?

Hello, Can you tell me about what kind of frame hold on NvBufSurface ? Only surface has object or both surface has object and surface has no object

Generally the NvBufSurface are allocated by nvstreammux, the surface hold the raw image. When an object detected from your model, nvinfer just attach the meta data on the gst buffer, it will not change the raw image. So I don’t think surface will include a object if you mean the object is the bbox/class id etc.
