NVENC and NVDEC APIs for Tegra X1

Where can I find the NVENC (or NVENCODE) and NVDEC (or NVDECODE) APIs for hardware acceleration encoding and decoding for Tegra X1?

Hi Sagar,
Please refer to Accelerated GStreamer User Guide

And Multimedia API in Documentation
https://developer.nvidia.com/embedded/dlc/l4t-documentation-24-2-1

These are frameworks supported for hardware acceleration.
