I've recently spent some time testing the implementations in various browsers. Chromium implements VA-API but it's disabled in official builds and fragile, breaking regularly. Webkit uses gstreamer-vaapi and I've had quality issues with that using both Intel (wrong colours) and AMD (blur) hardware.
I've seen Mozilla tracks issues for VA-API and VDPAU/NVDEC. Have you seen libplacebo[1]? It encapsulates the core video rendering used in mpv in a reusable library. mpv's video acceleration has been stable and flawless for both VAAPI and NVDEC (and DXVA, FWIW, but I've no experience with that) for years. In contrast to the browsers' and gstreamer va-api implementations, I've never had performance, stability or quality issues with mpv. In fact, hundreds (thousands?) of Firefox users use several WebExtensions to have videos played in mpv[2],[3],[4]. I haven't worked with either Firefox or mpv code so I can only speak from a user's perspective right now. I just thought, it might be worth to consider implementing libplacebo instead of rolling an own implementation for va-api and vdpau/nvdec. libplacebo is licensed in LGPLv2.1. Note: I initially wanted to post this in #1210726, quoting first comment: > This bug will track support for hardware decoding on Linux and the various > system available (VA-API, VDPAU, DXVA and others) > > There's so many frameworks available, it's hard to keep track! But this one's locked. If it suits better there, feel free to move this comment.

Even ignoring the GPU blacklist does not enable GPU decoding. How ever the patch is quite simple and it's already working using this PPA ( using libVA ) : https://launchpad.net/~saiarcot895/+archive/ubuntu/chromium-dev the corresponding patch is here : http://bazaar.launchpad.net/~saiarcot895/chromium-browser/chromium- browser.trusty.beta/view/head:/debian/patches/enable_vaapi_on_linux.diff that would be great if we could have this patch indefault Ubuntu chromium build, this situation is really sad right now, google use linux to make chromeOS so chromebook are really good at playing videos but GNU/Linux chromium is slow at doing it.
