When I execute a graph I created in graph composer 1.0.0, that uses an rtsp source it either fails on launch or runs for a few minutes and then fails with the following error code.
2022-06-29 11:36:20.992 ERROR extensions/nvdsbase/nvds_scheduler.cpp@309: Error from /GstPipeline:NvDsScheduler-Pipeline/GstDsNvUriSrcBin:NvDsSingleSrcInput…7610/nv_ds_single_src_input26…ce90: Failed to populate and link audio elements
2022-06-29 11:36:20.992 ERROR extensions/nvdsbase/nvds_scheduler.cpp@311: Debug info:
gstdsnvurisrcbin.cpp(1633): cb_newpad_rtspsrc (): /GstPipeline:NvDsScheduler-Pipeline/GstDsNvUriSrcBin:NvDsSingleSrcInput…7610/nv_ds_single_src_input26…ce90
The graph I created has the following structure NvDSSinglesrcinput-> NvDSStreamMux-> NvDsOpticalFlowVisual-> NvDsTee-> NvDsTiler-> nvDsRtspOut .
While I was trying to Debug this error I modified the deepstream-test2 graph to change the source to an rtsp stream and set the live source property of the stream mux to true. The deepstream test2 app then throws the same errors either when it starts or after a few minutes of running.
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
To recreate this you could change the uri of NvDsSingleSrc to a valid rtsp stream and the live source value to true of NVDSStreamMux in deepstream test2 graph file. You will first need to adjust permissions to modify a test app, then save the changes, export the parameters and run the graph. It will either fail on start or fail after a few minutes of running.
Any input on why this is happening would be great.
