Python-deepstream6.1-app , DeepStream-ImageData-Multistream-Redaction test problem

The YOLOV4 model has been successfully converted to TRT and tested successfully.
When test with yolov4.
I runned several python program, each program handles only one stream and output to one different UDP port and rtsp port.
Open 4 terminal Windows,
python3 -i rtsp://admin:CDWA11@

python3 -i rtsp://admin:FPTKS12@

python3 -i rtsp://admin:FPTKS12@

python3 -i rtsp://admin:123456Aa@

But run the fourth program:
Error: gst-resource-error-quark: Could not get/set settings from/on resource. (13): gstv4l2object.c(3507): gst_v4l2_object_set_format_full (): /GstPipeline:pipeline0/nvv4l2h264enc:encoder2:
Device is in streaming mode
Refer to Multiple RTSP in & out with Deepstream PYTHON - #17 by carloselilopezt

I switched to a 4-way RTSP camera。 (24.7 KB)

Same error.
