Understanding Hardware Acceleration

What is Hardware Acceleration?

Hardware acceleration uses GPU for video processing.

Benefits:

  • Lower CPU usage
  • Better performance
  • Power savings
  • Smooth playback

Acceleration APIs

Available APIs:

  • VAAPI: Video Acceleration API (Intel/AMD)
  • VDPAU: Video Decode and Presentation API (NVIDIA)
  • NVDEC/NVENC: NVIDIA decode/encode

VAAPI Setup

Install VAAPI

Install packages:

# Intel VAAPI
sudo pacman -S intel-media-driver libva-intel-driver

# AMD VAAPI
sudo pacman -S libva-mesa-driver

# VAAPI utils
sudo pacman -S libva-utils

Verify VAAPI

Check VAAPI:

# List VAAPI devices
vainfo

# Check codecs
vainfo --display drm --codecs

VDPAU Setup

Install VDPAU

Install packages:

# NVIDIA VDPAU
sudo pacman -S libvdpau libvdpau-va-gl

# VDPAU info
sudo pacman -S vdpauinfo

Verify VDPAU

Check VDPAU:

# Check VDPAU
vdpauinfo

Video Player Configuration

MPV

Configure MPV:

# Edit MPV config
vim ~/.config/mpv/mpv.conf

Add:

# Hardware acceleration
hwdec=auto
vo=gpu
gpu-context=wayland

VLC

Configure VLC:

# VLC > Tools > Preferences > Input/Codecs
# Hardware-accelerated decoding: Automatic

FFmpeg

Use FFmpeg:

# Hardware decode
ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -i input.mp4 output.mp4

Browser Acceleration

Firefox

Enable acceleration:

# Edit about:config
# Set:
media.ffmpeg.vaapi.enabled = true
media.ffvpx.enabled = false

Chromium

Enable acceleration:

# Launch with flags
chromium --enable-features=VaapiVideoDecoder

Troubleshooting

Acceleration Not Working

Check drivers:

# Check VAAPI
vainfo

# Check VDPAU
vdpauinfo

# Check GPU
glxinfo | grep "OpenGL renderer"

Codec Issues

Install codecs:

# Install codecs
sudo pacman -S gstreamer-vaapi

Summary

This guide covered VAAPI, VDPAU, video player configuration, browser acceleration, and troubleshooting.
