FFmpeg with NVIDIA NVENC Docker Image

This repository contains a Dockerfile to build a Docker image for FFmpeg with NVIDIA NVENC support. The image is based on nvidia/cuda:11.8.0-base-ubuntu20.04 and includes support for hardware acceleration using NVIDIA GPUs.

Features

• CUDA 11.8
• FFmpeg 5.1
• NVIDIA NVENC hardware acceleration

Prerequisites

• A machine with an NVIDIA GPU
• NVIDIA drivers installed
• Docker installed

Build Instructions

1. Clone the repository:

   git clone https://github.com/<your-username>/ffmpeg-nvenc-docker.git
   cd ffmpeg-nvenc-docker

2. Build the Docker image:

   docker build -t ffmpeg-nvenc .

Usage

Example FFmpeg Commands

docker run --rm --gpus all ffmpeg-nvenc:latest ffmpeg -hwaccel cuda -i input.mp4 -c:v h264_nvenc -preset slow -b:v 5M output.mp4

Verify NVENC Support

docker run --rm --gpus all ffmpeg-nvenc:latest ffmpeg -encoders | grep nvenc

Note for NixOS Users

On NixOS, the --gpus all option may not work as expected. Instead, you can use the --device nvidia.com/gpu=all option to enable GPU access for the container. Additionally, ensure your NixOS system is configured with the hardware.nvidia-container-toolkit module to support NVIDIA GPU containers.

Here’s an example of the adjusted command:

docker run --rm --device nvidia.com/gpu=all ffmpeg-nvenc:latest ffmpeg -hwaccel cuda -i input.mp4 -c:v h264_nvenc -preset slow -b:v 5M output.mp4
