Hi, I met following annoying warnings every time I refresh the ~/.cache/gstreamer-1.0/registry.aarch64.bin Is there any way to solve this issue?

Hi, You mean after cleaning _registry.aarch64.bin_, the prints are present always? After the cache is clean and in first run of gstreamer command, you should see some warning message being printed once. Afterward the warnings should disappear. ---

Yes, I see that once the cache is created, the warnings would disappear. But if I execute gst-inspect-1.0 -b , all of them are listed as in blacklist. So I’d like to know how to remove them from blacklist. How to solve the issue listed in previous post: undefined symbol: NvBufSurfTransformAsync ---

Hi, It seems like you don’t install DeepStream SDK. These warnings should disappear if DeepStream SDK is present. ---

Hi DaneLLL, Deepstream was installed already on my NX. Otherwise we would see more plugins in blacklist. user@linux:/var/log/ems$ dpkg -l | grep deep ii deepstream-6.0 6.0.0-1 arm64 Nvidia DeepStreamSDK runtime libraries, development files and samples It seems like missing some so files. e.g. If I execute ldd command, I can see ‘libtritonserver.so’ missing which causes ‘libnvdsgst\_inferserver.so’ listed in blacklist: **user@linux** : **/var/log/ems** $ ldd /opt/nvidia/deepstream/deepstream-6.0/lib/gst-plugins/libnvdsgst\_inferserver.so linux-vdso.so.1 (0x0000007f8b070000) libnvds\_meta.so =\> /opt/nvidia/deepstream/deepstream-6.0/lib/libnvds\_meta.so (0x0000007f8addb000) libglib-2.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libglib-2.0.so.0 (0x0000007f8accc000) libgobject-2.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libgobject-2.0.so.0 (0x0000007f8ac6f000) libgstbase-1.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libgstbase-1.0.so.0 (0x0000007f8abf8000) libgstreamer-1.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libgstreamer-1.0.so.0 (0x0000007f8aac8000) libnvdsgst\_helper.so =\> /opt/nvidia/deepstream/deepstream-6.0/lib/libnvdsgst\_helper.so (0x0000007f8aab1000) libnvdsgst\_meta.so =\> /opt/nvidia/deepstream/deepstream-6.0/lib/libnvdsgst\_meta.so (0x0000007f8aa9c000) libnvds\_infer\_server.so =\> /opt/nvidia/deepstream/deepstream-6.0/lib/libnvds\_infer\_server.so (0x0000007f8a3d9000) libstdc++.so.6 =\> /usr/lib/aarch64-linux-gnu/libstdc++.so.6 (0x0000007f8a245000) libdl.so.2 =\> /lib/aarch64-linux-gnu/libdl.so.2 (0x0000007f8a230000) libpthread.so.0 =\> /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000007f8a204000) librt.so.1 =\> /lib/aarch64-linux-gnu/librt.so.1 (0x0000007f8a1ed000) libc.so.6 =\> /lib/aarch64-linux-gnu/libc.so.6 (0x0000007f8a094000) /lib/ld-linux-aarch64.so.1 (0x0000007f8b044000) libgcc\_s.so.1 =\> /lib/aarch64-linux-gnu/libgcc\_s.so.1 (0x0000007f8a070000) libpcre.so.3 =\> /lib/aarch64-linux-gnu/libpcre.so.3 (0x0000007f89ffe000) libffi.so.6 =\> /usr/lib/aarch64-linux-gnu/libffi.so.6 (0x0000007f89fe6000) libgmodule-2.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libgmodule-2.0.so.0 (0x0000007f89fd2000) libm.so.6 =\> /lib/aarch64-linux-gnu/libm.so.6 (0x0000007f89f19000) libgstrtp-1.0.so.0 =\> /usr/lib/aarch64-linux-gnu/libgstrtp-1.0.so.0 (0x0000007f89eeb000) libnvbufsurface.so.1.0.0 =\> /usr/lib/aarch64-linux-gnu/tegra/libnvbufsurface.so.1.0.0 (0x0000007f89e6d000) libnvbufsurftransform.so.1.0.0 =\> /usr/lib/aarch64-linux-gnu/tegra/libnvbufsurftransform.so.1.0.0 (0x0000007f8872a000) \*\* > libtritonserver.so =\> not found \*\* libcuda.so.1 =\> /usr/lib/aarch64-linux-gnu/tegra/libcuda.so.1 (0x0000007f877e7000) libssl.so.1.1 =\> /usr/lib/aarch64-linux-gnu/libssl.so.1.1 (0x0000007f8775d000) libcrypto.so.1.1 =\> /usr/lib/aarch64-linux-gnu/libcrypto.so.1.1 (0x0000007f8751c000) libnvrm.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvrm.so (0x0000007f874d9000) libEGL.so.1 =\> /usr/lib/aarch64-linux-gnu/libEGL.so.1 (0x0000007f874b8000) libnvos.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvos.so (0x0000007f8749a000) libnvbuf\_fdmap.so.1.0.0 =\> /usr/lib/aarch64-linux-gnu/tegra/libnvbuf\_fdmap.so.1.0.0 (0x0000007f87487000) libnvrm\_graphics.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvrm\_graphics.so (0x0000007f87467000) libnvddk\_vic.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvddk\_vic.so (0x0000007f87449000) libnvddk\_2d\_v2.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvddk\_2d\_v2.so (0x0000007f87424000) libnvrm\_gpu.so =\> /usr/lib/aarch64-linux-gnu/tegra/libnvrm\_gpu.so (0x0000007f873e0000) libnvidia-fatbinaryloader.so.440.18 =\> /usr/lib/aarch64-linux-gnu/tegra/libnvidia-fatbinaryloader.so.440.18 (0x0000007f87371000) libGLdispatch.so.0 =\> /usr/lib/aarch64-linux-gnu/libGLdispatch.so.0 (0x0000007f87245000) ---
