Video decode acceleration issues on Chromium-based browsers in Ubuntu 22.04 often stem from compatibility problems with system libraries and codecs. While native installations may struggle with hardware acceleration, the Snap environment provides a self-contained solution that ensures video decoding functions correctly. Using the Snap version of your browser can significantly improve video playback performance and reduce CPU usage by enabling hardware-accelerated decoding.

Method 1: Install Chromium-Based Browser via Snap for Hardware Acceleration

Begin by removing your current Chromium-based browser installation to avoid conflicts. Open a terminal window by pressing Ctrl + Alt + T, execute the following command to uninstall the existing browser:
sudo apt remove chromium-browser

Confirm any prompts to remove the browser completely.

Next, install the Snap version of Chromium. Snap packages are containerized applications that come with their own dependencies, reducing compatibility issues. Run the following command in your terminal:
sudo snap install chromium

Wait for the installation to complete. This process may take a few minutes, depending on your internet connection.

After installation, ensure hardware acceleration is enabled within Chromium. Launch the browser, type chrome://flags in the address bar, and press Enter. In the search box, type “Hardware-accelerated video decode” and set it to “Enabled”. Restart the browser to apply the changes.
Verify that hardware acceleration is active. Visit chrome://gpu and look under “Video Decode” to confirm it shows “Hardware accelerated”. If it does, your browser will now correctly utilize your GPU for video decoding.

Method 2: Update Graphics Drivers to Improve Compatibility

If hardware acceleration still isn’t functioning properly after installing Chromium via Snap, the issue might be related to outdated or incompatible graphics drivers.

Open the “Software & Updates” application from the Ubuntu application menu. Navigate to the “Additional Drivers” tab.
Ubuntu will automatically search for available proprietary drivers for your graphics card. Select the recommended driver from the list provided and click “Apply Changes”. Wait until the installation completes.
Restart your computer to ensure the new drivers take effect. After rebooting, launch Chromium again and verify the hardware acceleration status by navigating to chrome://gpu.

Method 3: Adjust Browser Launch Flags Manually

If you’ve verified your drivers and installed the Snap version but still don’t see hardware acceleration enabled, manually adding command-line flags can sometimes resolve the issue.

Open your terminal and run the following command to edit the Chromium desktop file:
sudo nano /var/lib/snapd/desktop/applications/chromium_chromium.desktop
Within the editor, locate the line beginning with Exec=. Append the following flags after the existing command:
--enable-features=VaapiVideoDecoder --use-gl=desktop

For example, your edited line might look like this:

Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/chromium_chromium.desktop /snap/bin/chromium %U --enable-features=VaapiVideoDecoder --use-gl=desktop

Save the changes by pressing Ctrl + O, then exit the editor by pressing Ctrl + X.

Restart Chromium, and check again at chrome://gpu to confirm hardware acceleration is now active.

Following these steps should enable proper video decode acceleration in Chromium-based browsers on Ubuntu 22.04, improving video playback quality and reducing resource usage.
