Hello,

We are looking to execute some custom cropping on the frames directly between the pgie and sgie (i.e. this: pgie → custom crop → sgie).

I have traced how the cropping is currently done in the gstinver plugin all the way to “NvBufSurfTransformAsync” on line 1381 of “deepstream/deepstream-6.1/sources/gst-plugins/gst-nvinfer/gstnvinfer.cpp”. However I can only find the function declaration and not the actual definition (I.e: I can find the declaration on line 363 of “deepstream/deepstream-6.1/sources/includes/nvbufsurftransform.h”, but not the actual definition)

Could someone show me where the actual “NvBufSurfTransformAsync” is so I can potentially modify it to suit our needs.

Thanks so much!

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
