I'm surprised the HEVC Support figure is so low: 15%! I suppose HEVC is practically only supported by relatively modern devices which have hardware support for it. None of the OS or browser makers want to ship software support because they'd have to pay the license fee. (I paid $1 for the HEVC extension in the Windows Store but I'm sure that's exceedingly rare). Browsers can ship software AV1 support without needing to pay.
- clouddrover 3y agoIn addition to codec licensing fees, another problem with HEVC is the threat of content licensing fees: https://streaminglearningcenter.com/codecs/codec-royalties-on-content.html https://streaminglearningcenter.com/codecs/codec-royalties-o... It's just not worth it. Royalty-free formats (like AV1) are the way to go on the web.
- MrDrMcCoy 3y agoIsn't AV1 also better on technical merits like quality per megabyte? I know it's computationally slower, but that can be fixed.
