[Pkg-chromium-maint] Bug#856255: chromium: Enable "Hardware-accelerated video decode" flag

[Esokrates]

Package: chromium
Version: 56.0.2924.76-3
Severity: wishlist

Dear Maintainer,

Chromium is really inefficient at playing back videos due to hardware
accelerated decoding being forbidden on linux thus yielding high cpu usage, you can read about the upstream
bug here: https://bugs.chromium.org/p/chromium/issues/detail?id=463440

To summarize: Chromium devs do not want to give users the choice of
being able to control to use hardware acceleration or not.

I ask you to considering the following patch:
https://raw.githubusercontent.com/saiarcot895/chromium-ubuntu-build/master/debian/patches/enable_vaapi_on_linux.diff
and if you have concerns you could additionally set a default flag #disable-accelerated-video-decode in order to comply with upstream behaviour but leaving users the choice to use hardware accelerated decoding.

Would be nice to get feedback on this issue.
