wrenth04 / VAAPI-hwaccel-encode-Linux-Ffmpeg&Libav-setup.md
Created July 25, 2021 04:09 — forked from Brainiarc7/VAAPI-hwaccel-encode-Linux-Ffmpeg&Libav-setup.md
This gist contains instructions on setting up FFmpeg and Libav to use VAAPI-based hardware accelerated encoding (on supported platforms) for H.264 (and H.265 on supported hardware) video formats.

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

Minimalist static FFmpeg build on Ubuntu 16.04 with Nvidia NVENC enabled.

Original guide with a standard build is here.

With this guide, I'm adding more instructions to enable support for NVIDIA CUVID and NVIDIA NPP for enhanced encode and decode performance.

First, prepare for the build and create the work space directory:
