Details
Windows 7 lacks the ability to decode certain h264 profiles + levels. We've seen this in bug 1479203, and is an issue as high profile sites like twitter move towards using these profiles and levels. While Windows 7 is going to become unsupported on 2020-01-14 I expect to see a long tail of users remain on it.
My understanding is that recent OpenH264 builds have greater support here than Windows 7 does. If we could detect when we're encountering a stream that is supported by OpenH264 but not by Windows 7 we could use OpenH264 instead.
In addition to the specific example outlined above, we could apply this strategy on other platforms should the need arise.
about time this is added to firefox. honestly forcing people to upgrade windows or use another browser is simply silly.
would HEVC work fine for this workaround too?

My understanding is that HEVC (H265) is not supported by OpenH264 so this would not have an impact on the HEVC case.
well most of them are AVC for now and not HEVC. so at least we can get SOME videos start to work instead of half the stuff on big sites dont work.
