Metalens tech developments might solve the lens problem.

They not only increase the versatility of lenses (much lighter, thinner, and even achromatic focusing in a single lens element) but make them much easier to manufacture en masse.

Making a metalens is more like manufacturing a computer chip with photolithography processes, rather than the cutting and polishing of conventional curved lenses used today.

It makes sense to make a big change all at once for lightfield capture considering LF itself is a big change from conventional camera technology - might as well make a clean break.

We should probably start a "Encoding for VR" thread.

The version on their site is still from September 2020. Where are you finding daily builds?

The version on their website is the new version, they just haven't updated the changelog on their website yet.

Chrome now supports decoding AVIF content natively using existing AV1 decoders on Android and WebView. (Desktop support was added in Chrome 85.)

They should add D3D11 as well.

dav1d 0.8.2 'Eurasian hobby' the fast and lean AV1 decoder

This is a middle-size update of the dav1d decoder, from the 0.8.x branch.This release adds most of the remaining NEON optimizations for ARM, especially for 10/12bit bitdepth, in both ARM32 and ARM64.This release also split the post-filters into their own threads.

This release speeds up quite a bit the desktop version, notably in the coefficient decoding and the MSAC parts. It also introduces the first 10bit optimizations for x86.

Finally, this release improves the speed in numerous parts of the decoder, improves the player shipped and brings other fixes.
