Nvv4l2h264enc & nvv4l2decoder not working with multiple RTSP links

[nikhil.mehta1]

• Hardware Platform (Jetson / GPU): GPU RTX3050
• DeepStream Version: 6.2
• JetPack Version (valid for Jetson only)
• TensorRT Version: latest
• NVIDIA GPU Driver Version (valid for GPU only): 525.85.12

I am using 16 RTSP links with nvv4l2h264enc & nvv4l2decoder only 1 rtsp link is getting picked. While it works with x264enc.

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

RTX

The RTX serial GPUs only support 3 HW encoder sessions, so it is hardware limitation. Please encode the other 13 streams with software encoders.
