This is for save output to file. if you want to see the output via display, you need to use type 2. which GPU you are using?

[sink0]
enable=1
#Type - 1=FakeSink 2=EglSink 3=File
type=2

[neo21995]

but i have mentioned fakesink in here [sink0]
enable=0
#Type - 1=FakeSink 2=EglSink 3=File
type=1
sync=0
source-id=0
gpu-id=0

i am using rtx 3080 and why i am not able to see outputs in console

and also tested with type=2 but not outputs

[Amycao]

If you use Fakesink, you can not see outputs in console, it’s expected. fakesink will throw away the buffer it received.

any error you met when use Eglsink?

[neo21995]

if i use Eglsink i did not got any errors and also not output/display, is test1 python app suppose to display outputs or inference results

[Amycao]

Yes.
Where did you run? from terminal or from desktop?

[neo21995]

i am using WS from that in terminal i am running the this `python3.8 deepstream-test1.py file_path’

[Amycao]

You can not see the visualized output from terminal, you can use type 4 rtspstreaming, and use other tool like vlc to view the output.

[neo21995]

can you provide a example for that. i have tried all test apps but none gave me the output display screen, if i ran using deepstream-app -c config_path it will give output display.

set below properties in case of RTSPStreaming

rtsp-port=8554
udp-port=5400

you need to use other tool to see the output like vlc. when you run app, you will see the rtsp streaming address. input it in vlc tab “open network stream”, then you can see the output.

[neo21995]

solved: i was giving .mp4 as input, then changed to sample h264 video
