Linux Video Playback Checklist

Use this checklist on Linux machines where video playback or frame stepping feels slow or sluggish.

Baseline Packages

Install or update the common runtime and diagnostic tools:

sudo apt update
sudo apt full-upgrade
sudo apt install ffmpeg ffprobe vainfo vdpauinfo mesa-utils vulkan-tools

Make sure the user has access to GPU render devices:

sudo usermod -aG render,video $USER

Log out and back in after changing groups.

Tauri / WebKit Runtime

For Debian or Ubuntu systems:

sudo apt install libwebkit2gtk-4.1-0 libgtk-3-0 libayatana-appindicator3-1

Intel GPU

For newer Intel integrated GPUs:

sudo apt install intel-media-va-driver intel-media-va-driver-non-free va-driver-all

If VAAPI fails, try launching with:

LIBVA_DRIVER_NAME=iHD ./sam-tool

For older Intel GPUs:

sudo apt install i965-va-driver
LIBVA_DRIVER_NAME=i965 ./sam-tool

AMD GPU

Use Mesa VAAPI / VDPAU drivers:

sudo apt install mesa-va-drivers mesa-vdpau-drivers va-driver-all

In the app, prefer VAAPI.

NVIDIA GPU

Use the proprietary NVIDIA driver, not Nouveau, for best decode support:

sudo ubuntu-drivers autoinstall
sudo reboot

After reboot:

nvidia-smi
ffmpeg -hide_banner -hwaccels

In the app, prefer CUDA. Try VDPAU only as a fallback.

GStreamer / WebKit Video Stack

These packages are useful for WebKit video support, especially if native <video> playback is used:

sudo apt install \
  gstreamer1.0-libav \
  gstreamer1.0-plugins-base \
  gstreamer1.0-plugins-good \
  gstreamer1.0-plugins-bad \
  gstreamer1.0-plugins-ugly \
  gstreamer1.0-vaapi

Verification Commands

Check available acceleration support:

ffmpeg -hide_banner -hwaccels
vainfo
vdpauinfo
ls -l /dev/dri/renderD*

Test VAAPI:

ffmpeg -v verbose -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i input.mp4 -f null -

Test NVIDIA CUDA:

ffmpeg -v verbose -hwaccel cuda -i input.mp4 -f null -

App Settings

Recommended hardware decode setting:

  • Intel / AMD: VAAPI
  • NVIDIA: CUDA
  • Unknown or mixed systems: auto
  • If unstable: software

WebKit Workaround

On machines where WebKit or the Intel iGPU compositor is the bottleneck, try:

WEBKIT_DISABLE_COMPOSITING_MODE=1 ./sam-tool

This disables WebKit accelerated compositing and can improve playback on some Linux systems.
