    • Latest Qt 5.15, QtWebEngine from chromium-87 branch, on any modern Linux system that has libraries and drivers for HW video decoding in place

    • Linux/Wayland, Linux/X11, Linux/Yocto, Linux/Other display system

    Description

      Playing videos in QtWebEngine uses software rendering, making the playback choppy and battery intensive on lower end devices.
      In upstream Chromium/Blink, VAAPI acceleration can be enabled easily by tweaking settings or adding a small patch; but applying the patch on top of QtWebEngine's Blink fork doesn't work (from a quick look, it seems to be incompatible with the renderer).
