Details

libyuv does not support SIMD scaling on win64 build. See Bug 1295927. From Bug 1295927 Comment 21, there are several ways to add its support to libyuv.

Sotaro, are you working on this libyuv bug? We're changing the Firefox Windows installer's default from 32-bit to 64-bit Firefox in Firefox 53, so more users will be affected by any Win64 issues in libyuv.

btw, about 70% of 32-bit Firefox users are running Win64 OS and could be using 64-bit Firefox. We plan to upgrade these 32-bit Firefox users to 64-bit later this year.

The problem is because libyuv does not support 64 bit well. But it supports yuv420 to yuv conversion with simd. Then performance of b4bit is not too bad on majority of use cases.

The following is current status of chromium.

I get an advice from :jrmuizel and I am going to work for yasm support of libyuv.

Too late for firefox 52, mass-wontfix.

Is this supposed to be "New" or "Wontfix"?
