WebP is basically the format used to store i-frames in WebM/VPx videos. Google acquired on2 technologies for this tech many years ago, and it was to stop W3C from standardising a patent encumbered codec like H.265. These were all well intentioned.
WebP / WebM has all been superceded by AV1 / AVIF anyway. It never really took off, and it’s too late to start now.
I was tempted by Arc. Intel drivers always “just worked”, but they are just slow. Arc didn’t address the problem like I’d hoped, and AMD really got their shit together in the last 5 years or so.
