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.

Wow, their web page seems so atavistic. They're talking about replacing SW for ASIC encoding for advanced encoders. It's like rewinding the last 20 years of compression evolution.

In general, the more complex the codec, the bigger advantage SW encoders have had in quality over HW. AV1 is the most complex video codec, ever. It's hard for me to imagine how an ASIC could deliver competitive quality.

But maybe they've found magic! I look forward to seeing its output.

Does someone know why there is no SVT-AV1 release since [0.8.6] - 2020-11-28? Also auto builds are no longer published since 2021-02-16.

Support for PSNR calculation based on stream bit-depth.

New encoder control IDs added:
- AV1E_SET_ENABLE_RECT_TX
- AV1E_SET_VBR_CORPUS_COMPLEXITY_LAP
- AV1E_GET_BASELINE_GF_INTERVAL
- AV1E_SET_ENABLE_DNL_DENOISING

New aom_tune_content enum value: AOM_CONTENT_FILM

New aom_tune_metric enum value: AOM_TUNE_VMAF_NEG_MAX_GAIN

Coefficient and mode update can be turned off via
AV1E_SET_{COEFF/MODE}_COST_UPD_FREQ.

New key & value API added, available with aom_codec_set_option() function.
Scaling API expanded to include 1/4, 3/4 and 1/8.

- Enhancements:

Better multithreading performance with realtime mode.

New speed 9 setting for faster realtime encoding.

Smaller binary size with low bitdepth and realtime only build.

Temporal denoiser and its optimizations on x86 and Neon.

Optimizations for scaling.

Faster encoding with speed settings 2 to 6 for good encoding mode.

Improved documentation throughout the library, with function level
documentation, tree view and support for the dot tool.

- Bug fixes:
Aside from those mentioned in v2.0.1 and v2.0.2, this release includes the
following bug fixes:

Issue 2941: Decoder mismatch with --rt --bit-depth=10 and --cpu-used=8

Issue 2895: mingw-w64 i686 gcc fails to build

Issue 2874: Separate ssse3 functions from sse2 file.

Rumor has it that it's due to the bus factor.

The rumor isn't really new but according to sources from Moore's Law Is Dead, Intels Xe HPG will come with AV1 encoding support.

The fps comparison with RTX 3080 is a bit silly, I mean it must be CPU encoding, there is no hardware support from RTX 3080.
