Adds a complete multi-xlayer encoding pipeline for AV2. A single avmenc invocation can now encode multiple extended layers (xlayers), each optionally containing embedded layers (mlayers), and assemble their outputs into combined temporal units. Use cases include:

  • texture+alpha
  • stereo
  • subpicture tiling
  • spatial scalability

…pport

Implement a complete multi-xlayer encoding pipeline for AV2, enabling
independent encoding of multiple extended layers (xlayers) with their
outputs assembled into combined temporal units (TUs).

Making some tweaks to CLA bot config, which may have gone wrong. Ignore this for now.

@podborski : Actually, @lionelnicolas mentioned offline that you may have used "update branch" button from Github UI which created a merge commit with a different email address. That is why the CLA bot is complaining.

Pls rebase PR locally and force-push to fix this.

P.S. In future, you can use drop-down next to "update branch" and select "Update branch with rebase" instead.
