I tried to run the /opt/nvidia/deepstream/deepstream-5.1/sources/objectDetector_Yolo example with deepstream-app -c config_infer_primary_yoloV3.txt but got following error
**** ERROR: main:655: Failed to set pipeline to PAUSED**
ERROR from src_bin_muxer: Output width not set
Debug info: /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvmultistream/gstnvstreammux.c(2512): gst_nvstreammux_change_state (): /GstPipeline:pipeline/GstBin:multi_src_bin/GstNvStreamMux:src_bin_muxer
App run failed

How to solve this?


If you link the device with ssh, could you try to export the DISPLAY variable to see if it helps?

$ export DISPLAY=:0  # or export DISPLAY=:1
