As you can see below, I can’t get the libnvbuf_utils.so file in the new BSP package, which will cause some of my applications to not work properly.
please help me to check this issue.

Hi,
Sorry that it should be typo. The implementation is in

/usr/lib/aarch64-linux-gnu/tegra/libnvbufsurface.so
/usr/lib/aarch64-linux-gnu/tegra/libnvbufsurftransform.so

hello
Thank you for your warning, but I hope this error can be fixed in the future documentation, because I once thought this dynamic library file was essential!
