Built successfully the 2.3.0 version and checked into GIT and Andrey's package are in the process of building now. Ran 2 tests and all seems normal - it may be slightly faster and the file generated may be slightly smaller but it is too hard to tell with my simple tests. Thank you Terje for the notify of the new version.


Thanks!

Thanks, I take a look when the rpm from Andrey is ready

Installed the rpm on Leap 15.6 and test rendered one DV and one HDV file ok

Terje, I think if you are ok with this idea we can return to testing 10bit-vaapi patch ...
Hopefully in its final form it will just allow same format= string in encoding profiles as supported by per-file decoding opts files now ,,,

I'm not sure I understood the last line yet, but I should be ready to continue vaapi-testing to-morrow.

In the mean-time I just posted a system SVT-AV1 related issue with my single-user Cingg.

As seen on reddit, the Alliance for Open Media - AOM has released SVT-AV1 v. 2.3.0
The Scalable Video Technology for AV1 (SVT-AV1 Encoder) is an AV1-compliant software encoder library.

  • NEW FAST DECODE MODE

  • New fast-decode (2) to allow for an average AV1 software cycle reduction of 25-50% vs fast-decode 0 with a 1-3% BD-Rate loss across the presets

  • Improved fast-decode (1) option to increase its AV1 software cycle reduction by ~10% while maintaining the same quality levels

  • Improved --lp settings for high resolutions, with CRF gaining a ~4% improvement in speed and VBR gaining ~15%

  • Further Arm-based optimizations improving the efficiency of previously written Arm-neon implementations by an average of 30%

  • Address speed regressions for high resolutions first pass encode by tuning the threading parameters, with 1080p showing the biggest gains

  • Enabled AVX512 by default in cmake allowing for ~2-4% speedup


I hope system-wide nasm installed on Phyllis's build systems will cope with that .....
