  1. I´m trying to stream my Desktop with RTP using ffmpeg.

    libx264 seems to work fine. But I would like to test the performance of a hardware accelerated codec.

    ffmpeg -re -f dshow -i video="screen-capture-recorder" -vcodec libx264 -tune zerolatency -preset ultrafast -an -f rtp rtp://
    The NVENC codec works fine in other situations like this
    ffmpeg -y -rtbufsize 2000M -f gdigrab -framerate 60 -offset_x 0 -offset_y 0 -video_size 1280x1080 -i desktop -c:v nvenc -preset:v fast -pix_fmt nv12 out.mp4
    The Codec also apears in the list of available codecs.
    However this command doesn´t work

    ffmpeg -re -f dshow -i video="screen-capture-recorder" -vcodec nvenc -preset llhq -an -f rtp rtp://
    My machine is a Windows 10 with GTX 760

  2. First verify correct name for codec
    ffmpeg -encoders
    and later verify codec capabilities
    ffmpeg -h encoder=
    Seem your card use GK104 - you should use codec like
    -c:v nvenc_h264
