PyAV 17.0.1 Windows / vendor 8.0.1-5: matching binary licenses, exceptions and build records #262

Description

@CleanFix-Dev1

Hello PyAV binary-build maintainers,

We are completing redistribution records for MARNE V2T, a commercial Windows voice-to-text application. Our current package uses av-17.0.1-cp311-abi3-win_amd64.whl; the PyAV v17.0.1 vendor pointer identifies pyav-ffmpeg release 8.0.1-5.

I read PyAV-Org/PyAV#2270 and understand that PyAV's BSD source license does not by itself describe the bundled native binaries. To resolve the exact Windows bundle, could you point us to:

  1. The applicable license texts and complete notices for its FFmpeg, x264, x265 and OpenH264 binaries, including the actual text/scope of any commercial exceptions and whether downstream redistribution of these exact binaries is covered.
  2. The corresponding source revisions, patches, build recipe and any binary manifest for 8.0.1-5 as used by this Windows wheel.
  3. The matching source/rebuild or relink materials available to downstream distributors.

Our avcodec reports "LGPL version 3 or later" with --enable-version3, --enable-libx264, --enable-libx265 and --enable-libopenh264. Its identity is:

avcodec-62-3940774d70936a4a2ea89886c85e9317.dll
SHA-256: 45b2b9b08d077dacdcee9c77ecfb914b5f1d46848b413b5ca4678d06148c2204

The later comments in #2270 discuss a different PyAV/vendor version, so we do not want to assume those records cover 17.0.1. I emailed WyattBlue on September 22 and am asking here in case this project's build maintainers own the records; happy to consolidate in the preferred channel.

Links to existing records or a referral to their owner would be very helpful. This is a documentation/provenance request, not a request for a new license grant or a purchase commitment.

Thank you,
CHAD
