Does Jetson AGX Orin NVENC Support Sub-Frame (Line-by-Line) Encoding Without Full Frame Buffering? (FPGA via PCIe Input)

Hi,
You can enable slice output by configuring the options in 01_video_encode sample:

        -slt <type>           Slice length type (1 = Number of MBs, 2 = Bytes) [Default = 1]
        -slen <length>        Slice length [Default = 0]
        --sle                 Slice level encode output [Default = disabled]

Input frame data has to be full frames, so please do like:
