Which method is recommended when using a desktop GPU for multi-channel video decoding? gstreamer+nvv4l2decodr or video codec sdk?

Depends on your requirement.

DeepStream uses VideoCodec APIs for hardware video decoding part too.

Thank you very much. What should I pay attention to when decoding dozens of rtsp video streams using gstreamer+nvv4l2decoder, such as which environment variables need to be set?

There is video codec peformance data in Video Codec SDK | NVIDIA Developer.
