I’m working on a pipeline that process a few live videos and output them with rstp server respectively.
Now I have a simple test based on deepstream-test3(python),I added a nvstreamdemux after nvdsosd and created two nvegltransform&nveglglessink,the pipeline like :
uridecoderbin1 \ _______________________________________________ / nvegltransform1 ->nveglglessink1
______________ nvstreammux ->nvinfer ->… ->nvdsosd ->nvstreamdemux
uridecoderbin2 / _______________________________________________ \nvegltransform2 ->nveglglessink2
and I got :
Decodebin child added: source
Decodebin child added: source
Decodebin child added: decodebin0
Decodebin child added: decodebin1
Decodebin child added: rtppcmadepay0
Decodebin child added: rtph264depay0
Decodebin child added: alawdec0
Decodebin child added: h264parse0
In cb_newpad
gstname= audio/x-raw
Decodebin child added: capsfilter0
Decodebin child added: nvv4l2decoder0
Seting bufapi_version
Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 261

reference in DPB was never decoded
Frame Number= 0 Number of Objects= 1 Vehicle_count= 0 Person_count= 1
Segmentation fault (core dumped)
And I wonder how to debug my pipeline when I use deepstream-apps-python?
Is there any method like gst_debug_bin_to_dot_file()?
