1. What does "not work" mean here? Does Chromium not even launch, or does it start but not hardware accelerated? If the former, does dropping the flags (--enable-features=VaapiVideoDecoder etc.) makes it launch? > I remember in previouse snap it is working, but withtout vaapivideodecoder working. It is another problem, ... 2. So, in previous versions of the snap, Chromium would launch, but without hardware acceleration, correct me if I understand wrong. > ... but the wayland is sure working. 3. You mean that snap is supposed to work under Wayland, not that Wayland itself works, right? 4. I'm also interested in your `snap run --shell chromium`, `vainfo` output under Wayland. > does wayland mode conflict with vaapivdideodecoder feature ? I, for one, could get hardware acceleration in Chromium under Wayland working with `chromium --enable-features=VaapiVideoDecoder --disable- features=UseChromeOSDirectVideoDecoder --ozone-platform=wayland`. ** Description changed: To test the snap with VA-API changes, 1. Install the Chromium snap, sudo snap install --channel candidate/hwacc chromium - 2. snap run chromium --disable-features=UseChromeOSDirectVideoDecoder + 2.

Open a video, e.g. one from https://github.com/chthomos/video-media- samples 4. Enter about:media-internals in the address bar and note what the page says for kVideoDecoderName. Please report - The value for kVideoDecoderName from step 4. Success is typically {Vaapi,VDA,Mojo}VideoDecoder while failure is {FFMpeg,Vpx}VideoDecoder; - If failed, the video used for testing, including codec and resolution if possible; - Xorg or Wayland (`echo $WAYLAND_DISPLAY`); - Distro version (`grep VERSION= /etc/os_release`); - GPU (`lscpu`); - CPU generation (`lscpu`). About the last point, it may be that unfortunately only those with newer generations of Intel CPUs will have luck with this, but it's still an uncertainty.
