Does NX encode Support 4kP60?

Hi:
I have check the datasheet for our NX, encode dont support the 4Kp60, just has 2x 4K @ 30 (HEVC)?

Hi,
Please check
https://developer.nvidia.com/jetson-xavier-nx-data-sheet-v13
For Main/Main10 in HEVC, it can achieve 2160p30(2) in video encoding.

Hi Dane:
thanks,I have checked the datasheet,the decoder can achieve 2160p60,but the encoder just achieve 2160p30, its this right, NX cant support 4k/p60, the TX2 can support this?

Hi,
Single 4Kp60 should be good on TX2. we have profiled the performance by running 01_video_encode sample. Please refer to

got it thanks Dane

Hi Dane:
We have another question need your help,
What do you use or method to verify coding (encoding&Decoding) capabilities of TX 4Kp60,we want test it in our TX2 DK,thanks

Hi,
For video decoding, you can connect a 4K TV and run

$ gst-launch-1.0 uridecodebin uri=file:///home/nvidia/4K.mp4 ! fpsdisplaysink text-overlay=0 video-sink=nvoverlaysink sync=false -v

For video encoding, please run

$ gst-launch-1.0 videotestsrc num-buffers=600 ! video/x-raw,width=320,height=240 ! nvvidconv ! 'video/x-raw(memory:NVMM),width=3840,height=2160' ! nvv4l2h264enc maxperf-enable=1 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=false -v
