I’m running the pipeline below using deepstream python binding.
Do you mean you want to display the four videos on 4 screens? If so, you can use nvstreamdemux https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_plugin_gst-nvstreamdemux.html to separate the muxed streams after nvtracker and remove nvmultistreamtiler and nvdsosd.
Even obj_meta.object_id may be the same, the corresponding frame_meta.source_id is different.
Thank you for your reply.
I’m sorry for my poor English.
In my case, the same “object_id” but all “source_id” get 0.Probably because there is only one input source.
For example, I want to get the video on the upper left as “source_id = 0”, the video on the upper right as “source_id = 1”, and the video on the lower left as “source_id = 2”.
In this case, is there any metadata like “source_id”?
Or do I need to have multiple inputs with the same source?
Because after nvmultistreamtiler, all streams will be combined into one stream, there is only one stream in osd_sink_pad_buffer_probe() since osd_sink_pad_buffer_probe() is after nvmultistreamtiler.
“source_id” is OK before nvmultistreamtiler.
It seems that my understanding was not enough.
It became a clue to the solution.
Thank you!
