It's seems like there is a progress on getting Qualcomm Venus decoder
works on Snapdragon-based laptops so this feature could be useful for
these laptops too: https://github.com/bm16ton/yoga-c630-linux-kernel

I asked on the pi forum if they could help with the upstream bug report
https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=233552 . I like
the pi, but the people that make it are obnoxious. They are not going
to help.
I posted some more patches from endless os in that thread.

That's a good point. If a single component needs multiple different
fixes like separate ones for desktop and Pi then separate bugs are
really required.
This one is now reopened. Please reword the bug title here to make it
more obvious this one is about Pi/ARM only.

My concern is that v4l2 will be forgotten about on the other bug report.
Va-api won't work on the pi.

One of the benefits of Launchpad over other bug trackers is that we can
spread a single bug over multiple components. And those different
components have different Status values within a single bug. Bug 1424

I believe, although bug #1424201 is assigned to *chromium-browser*, it
is too general, as it also mentions and links to Mozilla bug reports.
Therefore, that one should be closed or treated as a “tracking rep

Thanks for the information all.
We would need to find out if video decoding hardware exists behind V4L2
in the desktop case, or if that's just for Pi/ARM hardware. I strongly
suspect it's the latter.
Also,
There is already a bug for vaapi - bug 1424201

Daniel, should we fill separate bugreport regarding VA-API? Or, perhaps,
if you understand situation better, you can fill it?

Vaapi is not the only mechanism that can be used for hardware decode.
V4l2 is an alternative, the one that will be used on the raspberry pi
with the open source vc4 driver (see blog posts
https://anholt.github.io/twivc4/2018/02/12/twiv/ ). I believe there is
some communication between chromium and
More information about VP9 and other decoding in V4L2:

I think that relates to Digital TV tuners only, and am not sure it
applies to machines that don't have any digital TV hardware attached.

Seems both statements are true :)
The above patches relate to parts of the Chromium source named V4L2. But
for the most efficient desktop video decoding you need to use VAAPI
(https://bugs.chromium.org/p/chromium/issues/detail?id=463440).
I'm not sure those two are related, or that the former can
V4L2 doesn't have anything to do with video decoding that I know of, but
maybe ARM is different...
Yes I think that should read "VAAPI", not "V4L2".

You meant VAAPI, not v4l2 , isn't it ?
