1761556 - Hardware acceleration stopped working on newer Intel drivers out-of-the-box (Intel HD Graphics 620)

Status: RESOLVED DUPLICATE of bug 1762125

(Core :: Audio/Video: Playback, defect)

Description

[stuerz]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:98.0) Gecko/20100101 Firefox/98.0

Steps to reproduce:

Install any Windows* DCH-Driver newer than 30.0.100.9955 (so 30.0.101.1069 and upwards) on Intel HD Graphics 620 (Intel i5-7200U iGPU).

Actual results:

After installation hardware acceleration stopped working. Restarting Firefox and rebooting didn't help. Other programs (Edge, VLC) still worked, so not a driver issue. Changing media.hardware-video-decoding.force-enabled to true in about:config fixed the issue.

Expected results:

When hardware acceleration is enabled it should work out-of-the-box without having to change settings in about:config, no matter which driver version installed.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hey, I just uploaded the troubleshooting information. They are from a new, clean profile (didn't try that before) with the same results:

1. Hardware acceleration doesn't work despite it being activated in settings
2. Changing media.hardware-video-decoding.force-enabled to true and restarting the browser fixes the problem

I also forgot to mention that I got the solution for my problem from [reddit] (https://www.reddit.com/r/firefox/comments/tnm637/hardware_acceleration_not_working_on_newer_intel/) where another person experienced the same problem and found the solution, so I'm not the only one who faced this bug.

I discovered this problem as well. It seems that 9955 is the last Intel driver that will do video acceleration with Firefox. I've tried Skylake, Kaby Lake and Gemini Lake processor graphics.

Is this a problem with the version number detection mechanism?

Mozilla should test their Intel driver version detection code on the latest Intel 30.0.101.1660 graphics driver.

This will also affect Intel Arc GPUs which uses the 30.0.101.1xxx driver version schema also, although Intel Arc driver is currently 300 build number version behind. In the future the driver version will also probably roll over to 102.xxxx driver version schema.

This bug needs to be fixed before Firefox 100.0 and ESR 102.0 ships.

Just remembered I filed this bug, some update since then fixed it for me, I guess if nobody else is still experiencing the problem it is resolved.

Reporter, does bug 1762125 look like your issue?

Yes, I think that's it, I guess that report got more traction and got fixed pretty fast.
