Is there a way to execute deepstream-test1 with X11 forwarding

[elhe]

I am currently trying to execute /opt/nvidia/deepstream/deepstream-5.1/sources/apps/sample_apps/deepstream-test1 without getting nvbuf_utils: Could not get EGL display connection.
I am using the Jetson Nano via ssh.
I would like to continue to use the Jetson Nano in a headless way and still use deepstream.
I am executing deepstream-test1, because I wan’t to get familiar with deepstream and eventually write my own binary classifier which would not need a X11 output. Is there a way to do this?

Thanks

As mentioned in https://docs.nvidia.com/metropolis/deepstream/DeepStream_5.1_Release_Notes.pdf

 On Jetson, running a DeepStream application over SSH (via putty) with X11 forwarding
does not work

[elhe]

Ok thanks.

Even if I run

/opt/nvidia/deepstream/deepstream-5.1/samples/configs/deepstream-app$ deepstream-app -c source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt 

With DISPLAY set to :0 or :1 with ssh without X11 forwarding I get:

No protocol specified
No EGL Display 
nvbufsurftransform: Could not get EGL display connection
No protocol specified
nvbuf_utils: Could not get EGL display connection
** ERROR: <create_multi_source_bin:1320>: Failed to create element 'src_bin_muxer'
** ERROR: <create_multi_source_bin:1411>: create_multi_source_bin failed
** ERROR: <create_pipeline:1294>: create_pipeline failed
** ERROR: <main:636>: Failed to create pipeline

When I run rm ~/.cache/gstreamer-1.0/registry.aarch64.bin , the EGL display error comes back. Otherwise it is only the src_bin_muxer error.

Do you have Display device connected on your NANO device?

[elhe]

No, but the xserver is running. I am only connected via SSH (I deactivated X11Forwarding on the Nano)

[mchi]

if you don’t have Display connected, can’t use eglsink.
could you replace it with fakesink or filesink?

My current sink config is the following (/opt/nvidia/deepstream/deepstream-5.1/samples/configs/deepstream-app/source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt):

[sink1]

When I run

opt/nvidia/deepstream/deepstream-5.1/samples/configs/deepstream-app$ deepstream-app -c source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt 

I get the same result again.

[mchi]

could you restart device and don’t set DISPLAY, and try again?

Thanks!

[elhe]

Thank you this worked.
