4 Chromium web browser

4.1 GPU

Chromium web browser has enabled hardware acceleration by default, supports WebGL, and can view hardware acceleration details by entering the URL chrome://gpu, as shown below:

4.2 VPU

Play a video in the browser, then use fuser on the command line to view the mpp device node to confirm that the vpu interface is being called:

pi@FriendlyElec:~$ fuser /dev/mpp_service
/dev/mpp_service:     3258

If there is no content output from the fuser command, it means software decoding.

4.3 Check Supported Hardware Decoding Formats

Enter about://gpu in your browser's address bar and scroll to the bottom of the page to view the "Video Acceleration Information" table.
After playing a video, enter about://media-internals in your browser's address bar to check if hardware decoding was enabled for the most recent playback.
