as the error shown, elgsink failed to initialize. please refer to 20. How to trouble shoot error cuGraphicsGLRegisterBuffer failed with error(219) gst_eglglessink_cuda_init texture = 1.
or you might use DS6.4 docker(DeepStream | NVIDIA NGC) if you are using docker.

livekha · January 3, 2024, 9:10am

we didnt use docker, i’ve tried reviewing but nothing works, can you give me some startup guide to start from like codes and places in my server to find the error

fanzh · January 4, 2024, 2:20am

please refer to this topic. we suggest using fakesink, which will not show the output video. here is the method.

add this modification patch.txt (168 Bytes)in deepstream_test3_app.
rebuild test3 then execute export NVDS_TEST3_PERF_MODE=1 && ./deepstream-test3-app dstest3_config.yml

Hello,

Please check if you’re using the correct display driver and cuda versions for DeepStream 6.2 and T4 GPU: Quickstart Guide — DeepStream documentation 6.4 documentation

livekha · January 11, 2024, 1:41am

we’re using deepstream 6.2

camilleh · January 11, 2024, 10:08pm

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

Your issue is typically indicative of the wrong nvidia driver version, but your driver version looks correct according to your nvidia-smi output (525.147.05).

Can you check that CUDA 11.8 is installed? You can see which CUDA versions are installed by running:

ls -l /usr/local | grep cuda

Please also check that your TensorRT version is 8.5.2.2 by running:

dpkg -l | grep TensorRT

You can see the full list of dependencies and their versions for DS 6.2 here:
