How to configure h265 stream?

[lida2003]

I have rtp h265 stream, it's black. It's OK when h264 streaming on my jetson orin nano board. Is there any thing wrong with my configurations?

[source0]
enable=1
type=3
uri=rtp://0.0.0.0:5600
num-sources=1
gpu-id=0
cudadec-memtype=0

EDIT: it seems using h264 for decoding....

EDIT2: If I try video-viewer rtp://@:5600 --input-codec=h265, then it's OK.
