• Issue Type:Unable to run deepstream sample application
• How to reproduce the issue ?
Download deepstream-5.0 and then Download the models instructed in the ReadMe file
Then got to:

/opt/nvidia/deepstream/deepstream-5.0/samples/configs/deepstream-app

Command:

deepstream-app -c source30_1080p_dec_infer-resnet_tiled_display_int8.txt

Output Error:

** ERROR: <create_osd_bin:77>: Failed to create ‘nvosd0’
** ERROR: <create_osd_bin:119>: create_osd_bin failed
** ERROR: <create_processing_instance:802>: create_processing_instance failed
** ERROR: <create_pipeline:1296>: create_pipeline failed

Quitting
App run failed

Can anyone help me to fix this issue

can you get the output of gst-inspect-1.0 nvosd
remove the cache, rm ~/.cache/gstreamer-1.0/ -rf and try again.
you can get more debug log for analysis
GST_DEBUG=:5 ‘sample app to run’

After I removed the cache it is working.
While I run application by the below format

lpr-test-app [language mode:1-us 2-chinese]
  [sink mode:1-output as 264 stream file 2-no output 3-display on screen]
  [ROI enable:0-disable ROI 1-enable ROI]
  [input mp4 file path and name] [input mp4 file path and name] ... [input mp4 file path and name]
  [output 264 file path and name]

./deepstream-lpr-app 1 1 0 TeslaCar.mp4 TFile.mp4 it is working fine

But if I run the application by this command

. /deepstream-lpr-app 1 3 0 TeslaCar.mp4 TFile.mp4 unable to see the live detection preview

The following is the error occured:

GST_DEBUG=:5 ./deepstream-lpr-app 1 3 0 TeslaCar.mp4 TFile.mp4
