Hello,
I am experiencing an issue with HEVC hardware decoding in Firefox on Windows 10.
System information:
OS: Windows 10 (latest updates installed)
Browser: Firefox ESR 128.8
GPU: (your GPU model)
GPU driver version: (your driver version)
Problem:
In about:support under the "Media" section, I see that HEVC (H.265) hardware decoding is not supported, while on Windows 11 with the same hardware, it works correctly.
What I have tried:
Installed HEVC Video Extensions from the official Microsoft website.
Enabled hardware decoding in about:config:
media.hardware-video-decoding.enabled → true
media.wmf.hevc.enabled → true
Updated GPU drivers to the latest version.
Checked HEVC support via FFmpeg – decoders are available.
Expected result:
Firefox should use HEVC hardware decoding on Windows 10, just like it does on Windows 11.
Actual result:
HEVC is only supported in software mode, and hardware decoding is not working.
Could you please help me resolve this issue?
Thank you!
