Hardware Video Decoding not working for Intel Quick Sync Video (QSV) on Windows 11
Hi, I've recently noticed that Firefox is not using Intel Graphics for hardware video decoding, here are the specifics:
- I tested this on two separate PC - one laptop with dual GPU (an Intel UHD 630 and NVIDIA GTX 1070) and one desktop with dGPU removed (leaving only an Intel UHD 630 by i7-9700K), on both PC I made sure to run Firefox on Intel GPU only. - According to information I gathered online, Intel UHD 630 should support H264 decoding and VP9 decoding without any problem. - I tested videos from Youtube (VP9, non-HDR video) and Twitch (avc/h264 video) - The exact same video, when played on Microsoft Edge (Chromium), uses Intel's hardware decoder without any problem. - On the dual GPU laptop, when being forced to run on NVIDIA's GPU, Firefox correctly uses the NVDEC decoder without any problem. - Both PC uses the latest Intel driver (30.0.101.1191)
I have attached copies from about:support page below.
In Firefox settings, under General -> Performance section, I have left "Use recommended settings" checkbox on.
Could someone help?

Hi TyDraniu, sorry I didn't see the reply.
But the problem seems to be fixed in Firefox 100. All hardware decoding works correctly now.
Thanks!
