1844614 - Add telemetry for Linux Hardware Decoding

Status: RESOLVED WORKSFORME

(Core :: Graphics, task)

Description

[Mike Kaply [:mkaply]]

Now that hardware decoding is enabled on Intel GPUs for Linux, it would be useful to have telemetry data on how it's used on release.

I am curious why this probe isn't sufficient -
https://sql.telemetry.mozilla.org/queries/82393/source?p_platform=Linux#204116

https://searchfox.org/mozilla-central/search?q=hardware_decoding&path=&case=false&regexp=false

Martin, maybe take a look at the source of the data here and see if it provides what you're looking for?

If you don't have access to that particular query but have access to t.m.o, the query is -

-- SCALARS_MEDIA.VIDEO_HARDWARE_DECODING_SUPPORT
-- payload.processes.content.keyed_scalars.media_video_hardware_decoding_support

-- break this down by platform

with dataset as (
select
count(distinct client_id) as count,
case
when hardware_decoding_supported.key = 'video/avc' then 'h264'
else replace(hardware_decoding_supported.key, 'video/', '')
end as codec,
case
when hardware_decoding_supported.value = true
then 'hardware'
when hardware_decoding_supported.value = false
then 'software'
end as supported
from
telemetry.main
cross join UNNEST(payload.processes.content.keyed_scalars.media_video_hardware_decoding_support)
as hardware_decoding_supported
where
DATE(submission_timestamp) >= DATE_SUB(CURRENT_DATE(), INTERVAL 7 DAY)
and normalized_channel = 'release'
and normalized_os = '{{platform}}'
and sample_id = 42
and payload.processes.content.keyed_scalars.media_video_hardware_decoding_support is not null
group by codec, supported
order by count desc
)

select * from dataset where count > 10

I don't have permissions to log in to sql.telemetry.mozilla.org.

it gives me:

Sorry, you do not have permission to access sql.telemetry.mozilla.org. Please contact the application owner for access. If unsure who that may be, please contact [e-mail] for support.

Ok, sorry about that. What kind of stats are you looking for? The query I posted displays a percentage graph comparing hardware and software decoding use. I'll post it here. I'll also try to get a historical trend graph going.

[Martin Stránský [:stransky] (ni? me)]

Cool Thanks. Looks like 20% od H264 decode is done on HW.

Martin, does this existing telemetry address your questions? If so, should we close this report?

Yes, works for me. Thanks.
