Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson AGX
• DeepStream Version 6.0
• JetPack Version (valid for Jetson only) 4.6
• TensorRT Version 8001
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs) question
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

Hello,
I’m having an issue running:
/opt/nvidia/deepstream/deepstream-6.0/bin$ deepstream-app -c …/samples/configs/deepstream-app/source30_1080p_dec_infer-resnet_tiled_display_int8.txt

The final error message I get is: Failed to create element ‘src_bin_muxer’
I’m connecting to the unit over a RDP.
I’ve a read a few posts on this forum concerning the same issue, but non of the suggestions worked for me:

Changing sink to 1 FakeSink or 3 File does not help.
Removing $HOME/.cache/gstreamer-1.0/registry.aarch64.bin does not help

I’ve ran gst-inspect-1.0 nvstreammux and it’s not found.

Please assist.

The eglgles does not support display over RDP. You need to change the sink to other kind sinks

user98065 · December 20, 2021, 4:57am

Thanks. Connecting locally to the unit (including physical display) + deleting the Gstreamer cache enable the “deepstream-app” to start running.

Could you please explain how to " change the sink to other kind sinks"? I mentinoed earlier that changing the sink type in [sink0] to Fakesink or File doesn’t enable the application to run.

Fiona.Chen · December 20, 2021, 6:06am

Please refer to DeepStream Reference Application - deepstream-app — DeepStream 6.1.1 Release documentation

user98065 · December 20, 2021, 7:55am

Thanks.

I found that I can run deepstream-app over RDP with FakeSink or FileSink by “unset DISPLAY”.
Doing so solves “EGL device not found” messages, and deepstream-app will run.
Unsetting DISPLAY also enables running with “[osd] enable=1” and “[tiled-display] enable=1” and have inference results written into the FileSink.

I got the same problem. I am using deepstream 5.0 with the following system components:

NVIDIA Jetson Xavier NX (Developer Kit Version)
- Jetpack 4.4 [L4T 32.4.3]
- NV Power Mode: MODE_15W_2CORE - Type: 0
- jetson_stats.service: active
Libraries:
- CUDA: 10.2.89
- cuDNN: 8.0.0.180
- TensorRT: 7.1.3.0
- Visionworks: 1.6.0.501
- OpenCV: 4.1.1 compiled CUDA: NO
- VPI: 0.3.7
- Vulkan: 1.2.70

I am following the documentation. Testing the sample config file source30_1080p_dec_infer-resnet_tiled_display_int8.txt . My system does not have x-server, so I have changed the config file. I still got the error message

Hi user43963,

Please help to try with DeepStream 6.0, and open a new topic if still an issue. Thanks
