Hello :)
We use computer that have 2gpu(rtx 3080)
but …
The rtx3080 knows that it has a maximum of 3 encodings.

So, we have 2 GPUs, but is it possible to get 3 input RTSPs for each GPU and output a total of 6 RTSP ?

nvstreammux, nvv4l2decoder, nvv4l2h264enc, nvv4l2h265enc all support “gpu_id” settings.

You can use two deepstream pipelines, each for one GPU with 3 streams to handle the 6 streams.
