Hi,
When I use NVENC to encode 720P video from camera, on xavier, over 4Mbps was consumed, any one know why?
Thanks!

Hi,
4Mbps is a bit strict for 720p. If there are continuous complex scenes, the bitrate may go higher. Suggest you try 8Mbps. And please check this post:
Hi,
For comparing h264 and h265, please use same YUV source and compare PSNR.
For example, you may download the source:
https://media.xiph.org/video/derf/y4m/park_joy_1080p50.y4m
Run
$ gst-launch-1.0 filesrc location= park_joy_1080p50.y4m ! y4mdec ! nvvidconv ! nvv4l2h264enc bitrate=14000000 control-rate=1 vbv-size=450000 ! h264parse ! qtmux ! filesink location= park_joy.mov
$ gst-launch-1.0 filesrc location= park_joy_1080p50.y4m ! y4mdec ! nvvidconv ! nvv4l2h265enc bitrate=14000000 control…
You may set CBR(control-rate=0) and vbv-size for a try.
