it run ok on gpu 0, but failed on gpu 1, 2

but the demo can run on deepstream 6.0.1

3

Could you open more log by adding the GST_DEBUG=3 to the command line?

4

logfile.txt (1.3 MB)

this is log file, I have committed the code , can you reproduce it ?

5

NO. It works well in my enviroment. How do you generate the rtsp source? Could you try the method below and test it?

docker run --rm -it --network=host bluenviron/mediamtx:latest
ffmpeg -re -fflags +genpts -stream_loop -1 -i /opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h264.mp4 -an -c:v copy -f rtsp rtsp://localhost:8554/raw
6

I have try the method to generator RTSP stream, it also occur again.

are you running in docker container nvcr.io/nvidia/deepstream:6.3-gc-triton-devel ?

I also test with deepstream 6.2 nvcr.io/nvidia/deepstream:6.2-devel, it work ok.

7

can you show the logs?

8

I use the nvcr.io/nvidia/deepstream:6.3-triton-multiarch docker. Could you try to set the memory-type to 2. When using multiple GPUs, we recommend using memtype_unified.

g_object_set(G_OBJECT(bin), "cudadec-memtype", 2, NULL);
9

Yes , it can run with

g_object_set(G_OBJECT(bin), "cudadec-memtype", 2, NULL);

But it would not happen with DS6.2, maybe some change ?

This is just a demo , we will add some plugins after streammux, so I will try if other plugins may cause error when we set

g_object_set(G_OBJECT(bin), "cudadec-memtype", 2, NULL);
10

As you test, you mean you can run with

g_object_set(G_OBJECT(bin), "cudadec-memtype", 2, NULL);

or

g_object_set(G_OBJECT(bin), "cudadec-memtype", 0, NULL);

you can run with both setting? Or you adjust the code?

11

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

It just can run with "cudadec-memtype", 2. Also it’s just for nvurisrcbin. About how to set the memory-type to unified of other plugins, you need to refer to our guide.
For nvstreammux, you need to set nvbuf-memory-type.
