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

The YOLOV4 model has been successfully converted to TRT and tested successfully.
When test deepstream_imagedata-multistream_redaction.py 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 deepstream_imagedata-multistream_redaction.py -i rtsp://admin:CDWA11@192.168.1.9/h264/ch1/main/av_stream

python3 deepstream_imagedata-multistream_redaction.py -i rtsp://admin:FPTKS12@192.168.1.98/h264/ch1/main/av_stream

python3 deepstream_imagedata-multistream_redaction.py -i rtsp://admin:FPTKS12@192.168.1.98/h264/ch1/main/av_stream

python3 deepstream_imagedata-multistream_redaction.py -i rtsp://admin:123456Aa@192.168.1.70/h264/ch1/main/av_stream

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。
demux_test4.py (24.7 KB)

Same error.

hareware encoding has seesion number limitation, you can use software encoding in the fourth program, please refer to this in configuration file.
“encoder type 0=Hardware 1=Software
enc-type=1”

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
