How to display video in same widow in multiple parameters mode

**• Jetson
**• Deepstream-5.1
**• 4.5.1
**• TensorRT7.1
• NVIDIA GPU Driver Version (valid for GPU only)
**• new requirements

I uses multiple parameters to run mutiple model in deepstream-app.
for example :
config_1.txt : model 1 , [source0]
config_2.txt : model 2, [source1]
config_3.txt : model 3, [source2]

deepstream-app -c config_1.txt -c config_2.txt -c config_3.txt

it can be run successly ,but it will open 3 windows to display difference videos.
I want to show it in same window , what can I do?

thanks.

Please refer below link. nvmultistreamtiler can composite all video source to one.

DeepStream Reference Application - deepstream-app — DeepStream 6.0 Release documentation (nvidia.com)

I try to set enable =2 in tiled-display, and link-to-demux=1 in sink,
but it still display in differenct windows.
please help to check if it have problem.
I test it in Deepstream6.0, jetpack 4.6. jetson nx.

the following the config.
config1.txt :
[tiled-display]
enable=2
rows=2
columns=2
width=1920
height=1080
gpu-id=0
nvbuf-memory-type=0

[source0]
enable=1
type=3
uri=file://test.avi
num-sources=1
gpu-id=0

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

config2.txt:
[tiled-display]
enable=2
rows=2
columns=2
width=1920
height=1080
gpu-id=0
nvbuf-memory-type=0

[source1]
enable=1
type=3
uri=file://test.avi
num-sources=1
gpu-id=0

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

anyone can help me?

Can you use one configure file? Or setup pipeline by yourself.

I need to run multiple models in primary gie. so I have to use multiple config file.
