Qt WebEngine does not currently support hardware accelerated decoding of videos.


- What is video acceleration and do you really need it? Could you use a proprietary solution?

- To off-load CPU, especially important for embedded devices

- Needs to be supported by GPU hardware and drivers, usually only supporting some encoding

- Link to Chromium docs on video acceleration


  • Linux: Video acceleration (VA) API, gstreamer, and proprietary solutions
  • Windows: directX API
  • macOS: ?

Qt WebEngine

Being considered:

  • Enabling VA API in Qt 5.10 (?) for Chromium 60
  • Implementing a punch hole in scenegraph
  • Supporting gstreamer
