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!
