Jetson nano support encoding or decoding h264/h265/vp9 in yuv444?

Does jetson nano support encoding or decoding h264/h265/vp9 in yuv444?
I want to receive yuv444 and encode it with yuv444 not yuv 420.
Thanks!

Hi,
We support encoding on TX2 and Xavier. It is not supported on Jetson Nano.

If you have TX2 or Xavier, you may try the steps:

H.264 lossless encoding

Hi, In tegra_multimedia_api, we support lossless encoding in YUV444 input frames. Please refer to 01_video_encode and try: $ gst-launch-1.0 videotestsrc num-buffers=60 ! 'video/x-raw, width=(int)1280, height=(int)720, format=(string)Y444' ! filesink location=origin.yuv $ video_encode origin.yuv 1280 720 H264 out.264 --elossless
