Hi, I am facing the below warnings, which is not allowing to create the deepstream element.

Can you run any DeepStream reference samples? Your driver version seems to be too old, the recommended driver is 525.85.12, refer here Quickstart Guide — DeepStream 6.2 Release documentation (nvidia.com)

3

Does deepstream-6.2 supports 2070 RTX?

4

Yes, DeepStream can work well if the dependencies(driver/tensorrt/cuda) are installed correctly.

6

What driver version is supported for Deepstream 6.2 version?

7

Can you tell me, how to check if all of them are installed properly.

8

The dependencies as below, more details can be found in the link of my first reply:

  • Ubuntu 20.04
  • GStreamer 1.16.3
  • NVIDIA driver 525.85.12
  • CUDA 11.8
  • TensorRT 8.5.2.2
9

could you check is every xxx.so file show on the error message is under /usr/lib/x86_64-linux-gnu/gstreamer-1.0 directory?
for example check libgstlibav.so is under /usr/lib/x86_64-linux-gnu/gstreamer-1.0 directory.

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

Are you running in docker?

Check two file randomly and exist in /usr/lib/x86_64-linux-gnu/gstreamer-1.0:
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstopenmpt.so
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstmpeg2dec.so

By default “libgstlibav.so” doesn’t exist in docker, it appears after running script “./user_additional_install.sh” in /opt/nvidia/deepstream/deepstream-6.2 to install some additional package.
