The other typical structures to convey codec information to the hardware are still suspiciously absent however, so it may not be fully finalized.

Sorry for the delay: A bug in shaderc blocked the suite until I disabled mpv temporarily... / VPx is here.
The media-autobuild suite did not yet build an aomenc binary that reports itself as v2.0.0, maybe a merge to master is missing? New uploads: (MSYS2; MinGW32 / MinGW64: GCC 10.1.0) AOM v1.0.0-errata1-avif-893-g9c38f3b0f rav1e 0.3.0 (02018bf / 2020-05-19) dav1d 0.7.0 (cbe05cf / 2020-05-19) |

Has this encoder something like a github repo? It seems there is absolutely no version information provided by the encoder.

If you use the media-autobuild suite:
In the media-suite_compile.sh you can read that it is downloaded from https://aomedia.googlesource.com/aom by a helper function do_vcs() in media-suite_helper.sh which handles a variety of methods. Apparently there is a git repo behind this URL, which appears as website with an own design in a browser. There are branches (MABS uses the "master" branch usually) and tags. Their relation is not very obvious, though. I am not sure but I believe there was an additional shell script which collects required information to store the version information as "tag+updatecount" in a header file...

Thanks for the info LigH, so no issue tracker. Maybe a developer reads here and bookmarks this post as feature request, I would like to suggest providing version info, examples:
Code:

Build script for vs2019 git repo: https://github.com/marcomsousa/build_aom In every libaom commit (in master branch) a build is automatically generated: https://ci.appveyor.com/project/marc...ld-aom/history Now it goes with v2.0.0-255-ge0be17e7f The version you can see if you perform: Quote:

is this it ?
https://bugs.chromium.org/p/aomedia/issues/list google look at and respond in it, eg by addressing a couple of very trivial things I may have raised. Last edited by hydra3333; 20th May 2020 at 10:38. |

There must have been a merge in the meantime.
AOM v2.0.0-255-ge0be17e7f And yes, the bug tracker should match. Last edited by LigH; 20th May 2020 at 15:19. |

Looks like Tiger Lake will be the first x86 uArch to support AV1 HW decoding:
https://pbs.twimg.com/media/EYn7NM0V...=png&name=orig https://pbs.twimg.com/media/EYn7f9BU...=png&name=orig https://pbs.twimg.com/media/EYn72cxU...=png&name=orig https://pbs.twimg.com/media/EYn8WKXU...=png&name=orig I do hope NVIDIA will support it as well in Ampere.

I note they don't list bit depths for AV1. Does that imply 8-bit only? They don't list it for AVC either, does Intel support >8-bit AVC decode, or only with more advanced codecs. |
