My platfrom is AGX Xaiver(16G), I try to encode the yuv frame into H.264 with nvenc encoder. The application doesn’t work after a period of time, I can get buffer from capture_plane, but the size is always is 0. How to deal this ? where can I get more usefull information?

Hi,
Please share which release version you are using. And do you run this sample:

Hi,
We would suggest upgrade to Jetpack 5.1(r35.2.1) and give it a try. Or if Kernel 4.9 is good for you, you may try Jetpack 4.6.3(r32.7.3)

Hi，
Any way to get more detail? or where can I get nvenc driver log?

Hi,
You can add --dbg-level 3 to get more log prints:

01_video_encode$ ./video_encode 1080.yuv 1920 1080 H264 a.264 --dbg-level 3
