GStreamer command for Windows use NVIDIA h264enc HW accelerator

Hi Team

I need to deliver Video over RTP h264 using Gstreamer.
In order to avoid overload the CPU with h264 enc/dec I Like to use the NVIDIA HW accelerator plugin such as omxh264enc or nvh264enc / dec.
Can you help me and point me where I can get GStreamer with nvidia plugins for h264 ?
