deepstream-test1-app sample is running without showing anything

The question might be basic…
I have T4 with Ubuntu 18.04. I tried running deepstream-test1-app from both docker and also my local deepstream installation. In both cases I see in the terminal that the application is running but I don’t see anything .
Is there a way to view the video with the results?

Do you see any error on the output, T4 do not have display port, you can follow this to setup virtual screen,
https://elinux.org/Deepstream/FAQ 5A, then run on desktop;
another way, you can use deepstream-app to run with sink type 3 File, you can use config source30_1080p_dec_infer-resnet_tiled_display_int8.txt, change default sink type to below

[sink1]
enable=1
type=3
#1=mp4 2=mkv
container=1
#1=h264 2=h265 3=mpeg4

only SW mpeg4 is supported right now.

codec=1
sync=0
#iframeinterval=10
bitrate=2000000
output-file=out.mp4
source-id=0

Hi, I have tried the second suggested option and get the following error after a “deepstream” window is opened for a moment:

App run failed

By the way, If I run with fakesink I get “tQuitting
App run successful”
but don’t see anything

please get below sink type disabled and try again

[sink0]
enable=0
#Type - 1=FakeSink 2=EglSink 3=File
type=2
sync=0
source-id=0
gpu-id=0
nvbuf-memory-type=0

Thanks! works and generates out file
