• 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)

  1. I am using deepstream-app with nvmultiurisrcbin. I have added 4 rtsp urls initally with num-source-bins=4. I have put max-batch-size=20. I have also added 8 rtsp sinks to stream the output for every source.
  2. When I am running the app, rtsp streams are coming to 4 sinks. But when I add new rtsp source using rest API , new rtsp sink is not getting created. If I use tiler with eglsink, I am able to see new src getting added and output displayed on screen. How to resolve this?
  3. How to dynamically/in runtime create/remove sink when new source is added using nvmultiurisrcbin?

Below is the app config:

The deepstream-app does not support dynamically generate sink with nvstreamdemux. It is no use to set more sinks than needed in the configuration file.

You need to implement by yourself. To request new src pad from nvstreamdemux after the new source has been added to the nvstreammux new sink pad. It is a normal pad add/remove operation in GStreamer. Don’t forget to set the elements in proper state when you operate on the pads. GStreamer: open source multimedia framework

Thank you for the reply @Fiona.Chen. It will be quite helpful if you can point to an example or guide.

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

The pad add/remove is just normal GStreamer pad operations. You can refer to deepstream_reference_apps/runtime_source_add_delete at master · NVIDIA-AI-IOT/deepstream_reference_apps (github.com) for how to dynamically add/remove elements in PLAYING pipeline.
