I'm wanting to test av1 and some other new encoders, and have been using media-autobuild-suite to try and build a ffmpeg with it. It keeps failing trying to install cargo-c as part of rav1e. I've deleted the folder. I've removed rav1e from the build list, but it keeps always trying to compile it and then failing. It's been happening for a couple of weeks now, and has persisted despite several rav1e updates in that time period.

Any suggestions?

Code:
dav1d git  .................................................. [Up-to-date]
  Running git clone for rav1e...
┌ rav1e git  .......................................... [Recently updated]
├ Running submodule...
├ Running install-cargo-c...
Likely error (tail of the failed operation logfile):


error: aborting due to previous error

error: failed to compile `cargo-c v0.6.2`, intermediate artifacts can be found at `C:\Users\benwagg\AppData\Local\Temp\cargo-installyZ6Pas`

Caused by:
  could not compile `cargo-c`.

To learn more, run the command again with --verbose.
install-cargo-c failed. Check C:/Users/benwagg/Desktop/media-autobuild_suite-master/build/rav1e-git/ab-suite.install-cargo-c.log
This is required for other packages, so this script will exit.
  Creating diagnostics file...

All relevant logs have been anonymously uploaded to https://0x0.st/iuKh.zip
Copy and paste [logs.zip](https://0x0.st/iuKh.zip) in the GitHub issue.
Make sure the suite is up-to-date before reporting an issue. It might've been fixed already.
Try running the build again at a later time.

vlc player 3.0.9.2 is out, the first update in 8 months. Pretty sure it includes the latest dav1d decoder.

Is this an extra download or does Win10 comes with this AV1 extension decoder ?

If it is an extra download, any url ?

SIMD optimisations for 10+ bpc content on x86 are still completely missing, you might get better performance on a recent W10 on ARM laptop due to the NEON optimisations for ARM64 added more recently.

With 8 bpc content though both the ARM64 and x86 platforms are mostly done now for SIMD optimisation (excepting AVX512), I would not expect any dramatic speedups for that now without adding more cores.

I'd be surprised to see material perf improvements by adding AVX512, at least on current gen CPUs, due to aggressive thermal throttling.

This will hopefully change over time, just like we saw AVX2 become much more useful in the second major generation of implementations.

Unfortunately you still can't search/skip the svt-av1 stream quickly if you use the default value --irefresh-type 1 (CRA; Open GOP).

Since there is no hint if it is a svt-av1 encoder or dav1d decoder problem, I tested the latest version.

Does anyone have a hint?

How did you mux the file? The problem suggests that the muxer did not mark the keyframes in the container index.

You need to file a bug report (or feature request) with mp4box to add support for invisible keyfames, which is how AV1 calls non-IDR / open-GOP keyframes.

They have updated the extension pretty regularly, alas without release notes.

Pretty cool, Google has announced using AV1 in their Duo voice chat app, targeting 30 Kbps!

Wow 30 kbps, that is pretty incredible, even old 2-2.5g mobile networks and ancient DSL could field that, which is probably exactly the point.

Sounds like they are also trying to compete with that Zoom app and Skype for group video calls with the current demand for it skyrocketing.

Even with them looking to expand to 12 participant group calls it would only be 330 kbps down and 30 kbps up.
