To reproduce the problem, add an additional source in the configuration file /opt/nvidia/deepstream/deepstream-7.1/samples/configs/deepstream-app-triton/source1_primary_detector.txt.
More specifically, the changes made to the sample file are an additional column in the [titled-display] section:
[tiled-display]
enable=1
rows=1
columns=2
width=1280
height=720
…
And the additional [source1] (same as [source0]):
[source1]
enable=1
#Type - 1=CameraV4L2 2=URI 3=MultiURI 4=RTSP
type=3
uri=file://../../streams/sample_1080p_h264.mp4
num-sources=1
#drop-frame-interval=2
gpu-id=0
cudadec-memtype=0
This is the result. Notice that there are no labels.
I left-click one of the tiles, that tile image takes the entire window and the labels start showing again.
If I then right-click, the tiled visualization returns and the labels stop appearing again. Is this by design or a bug? How do I force the labels to also appear in the tiled display?
