There are still some crashes from other graphic cards which we didn't block, such as 0x0a16 (Intel HD Graphics Family) and 0x1616 (Intel HD Graphics 5500). But 0x1616 in on Broadwell, which should support VP8 HW decoding already based on the wiki documentation.

Those crashes all happened on driver verision 10.18.14.4264.

Attachment: Bug 1761332 - block all Haswell devices and a certain version of intel driver for VP8 hw decoding.

This is a follow-up for bug1760464, we observed more crashes from devices which we didn't added to the block list before.

Therefore, we decided to block all Haswell GPUs for VP8 HW decoding (Intel supports that sine Broadwell) and one other device (HD 5500 even if it's Broadwell series).

According to this report there are still some crashes from 0x0416 (Intel HD Graphics 4600) which is already listed in Haswell family.

But I suppose this block rule should take effect and block that device? So I don't know why we can still see crashes from that device. Jeff, do you have any idea about this? Thank you.

No, that seems really odd. Perhaps the blocking is not working (e.g. we call into mfx_mft_vp8vd_64.dll) for some other reason?
