Description

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!

IMHO this Bug needs Plattform set to Linux (easier to search)
[POWER] tag to the Whiteboard
Probably also should become Meta Bug
And Bug 563206 should be duped to this Bug

> Is there a reason the priority would go from P2 to P3?

We were using P1, P2 and P5. Now we're using P1, P3 and P5. The priority hasn't changed.

> Lack of hardware acceleration is the worse offender on Linux right now.

How did you come to that conclusion?

The following things are more important:

* Basic layers is slow in 47; much better in 48
* GL Layers isn't enabled yet
* WebGL does readback (only affects 360)

Even if you enable H.264 hardware decoding you miss out on the network performance (better compression) of VP9. If you fix the above issues then most users will be network constrained by a significant margin.

You may be barking up the wrong tree. Consider that what you're really after is better video performance. Most CPUs that have struggle to decode video don't have working VA-API. 

> I do not get why it would not even go the other way, right to P1 ?

P1 is mostly used for security, crash, regression and significant webcompat issues. P3 is for backlog which is everything else that matters.
