Ensure that the h264ify Chromium extension is enabled.Ĭhromium on Raspberry Pi OS comes with uBlock Origin and h264ify extensions installed by default.
Hardware-accelerated video decode chrome://flags/#enable-accelerated-video-decode.Override software rendering list: chrome://flags/#ignore-gpu-blocklist.Enable hardware acceleration in Chromium browser.Įnable the following flags in chrome://flags: To enable hardware acceleration in Chromium browser running on Raspberry Pi OS (Raspberry Pi 4), follow the 3 steps (well, more like 2.5) below:ġ. However, since I can only test this on a Raspberry Pi 4 Model B, and I don't like to write articles about things I can't test myself, I'm only focusing on Raspberry Pi 4 and instructions for it in this article.Įnable hardware acceleration in Chromium browser running on Raspberry Pi OS (Raspberry Pi 4) This isn't required for the Raspberry Pi 4. I've tested this using a Raspberry Pi 4 Model B (using Raspberry Pi OS), so I can only confirm this is working for it. According to this, you may need to enable OpenGL with fake/full KMS using raspi-config for older Raspberry Pi models (I'm not sure if extra steps are required on older models). You'll only need to enable some Chromium browser flags below there's also a "fix" for screen tearing which occurs when playing hardware-accelerated fullscreen videos. For Raspberry Pi 4 there's no need to install extra packages, enable OpenGL, and so on, as those are already enabled. Raspberry Pi OS comes with everything that's needed to run Chromium with hardware acceleration on a Raspberry Pi 4, but it doesn't work out of the box.
As a side note, this is a prerequisite for an article I plan on writing soon. In my case, using a Raspberry Pi 4 Model B, the main Chromium gpu and renderer processes went down from ~160% and ~130% to under ~30% and 23% CPU usage (according to htop) after enabling hardware acceleration. This article explains how to enable hardware acceleration in Chromium browser running on Raspberry Pi OS (for Raspberry Pi 4).īy enabling GPU acceleration, the CPU usage should be much lower when playing supported videos (for example on YouTube).
