Juste a note : 99% of users don t have a GPU that can accelerate vp9.
Disabling vp9 enable them to Get h264 accelerated vidéos ( like in YouTube)

I would welcome this, watching 1080p and also 720p videos on Chrome lets my
Ivy Bridge Ultrabook burn at 72-77°C and 80-90% CPU usage, where IE11 just
uses 6-14% CPU.

Yoga 3 Pro seems to have no hardware acceleration for VP9. So watching 4K
video in Youtube in Google Chrome is not possible, staggering, unwatchable.

Same video, same machine, in IE11 butter smooth. It uses the H.264 codec.

Please make an option to disable VP9 or choose the codec the user prefers.

Given the presence of the h264ify extension and recent performance numbers
for vp9, it doesn't make sense to implement this.

For me (on a Yoga 3 Pro) h264ify does indeed work - at least partially. The
video is reported to be x264 and not vp9. But it doesn't change the fact
that the video is not hardware accelerated for some reason. Same video on
IE is butter smooth, cpu at most 30%-40%. On Chrome cpu is 100% and frames
are dropped like crazy.

If you have a newer intel ultrabook you may be hitting another problem,
issue 499696. To see if a given video has hardware acceleration find the
player in chrome://media-internals and see if "GpuVideoDecoder" is present
in the properties section.

Unfortunately, at present, our h264 hardware decoder implementation uses
copy-back, so it may not work as smoothly as IE in this case (issue 464774
tracks this to some extent).

Lena, no idea how it works for you, when I still have forced vp9 with
h264ify enabled. Win7\8.1\latest Chrome. Absolutely useless plugin.
