H.266/Versatile Video Coding (VVC)

Re:H.266/Versatile Video Coding (VVC) by TheRealSteel on Monday July 06, 2020 @10:21AM (#23748164)

H.265/HEVC takes about ten times as much computation to encode than H.264 [1], so H.264 still has legitimate technical use cases, even with licensing/patents aside.

This makes it great for a company like Netflix or YouTube, but less good for one-to-one and/or battery sensitive use cases like video calls. However, specialized chips help, and some mobile devices can record in HEVC in real time (mine from 2019 can). I believe current smartphones have HEVC encoding hardware, but I'm struggling to find a source for that right now.

I haven't seen the details of this new codec yet, but it's quite possible it also has a large encoding cost which will make it better suited to particular use cases, as opposed to a blanket upgrade.

iPhone 7 onwards[1], Qualcomm Snapdragon 610 onwards[2], and Intel Skylake and later CPUs[3] can all encode and decode H.265 in hardware to varying profile levels.

QuickSync is actually a feature of Intel's integrated GPU. Parts without GPUs, no matter how recent, don't have QuickSync.
