VA-API 1.0.0

Summary

This change is about upgrading Package-x-generic-16.pnglibva and others to version 2.0. This change affects several multimedia players as there are both API and ABI changes. This will allow some VA-API backends to be updated, improving support for recent hardware.

Owner

  • Name: Nicolas Chauvet
  • Email: kwizart - at - fedoraproject.org
  • Release notes owner:
  • Product: Spins / Workstation
  • Responsible WG: Desktop

Current status

  • Targeted release: Fedora 28
  • Last updated: 2018-01-29
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Updating to VA-API 1.0.0 will allow to fix and clean-up issues with the API as sum-up in this upstream topic VA-API 1.0.0:

  • fix errors in API/data structure definition, e.g. 01org#32
  • add new features, e.g. 01org#69,
  • deprecate some useless API/data structures, e.g. libva-tpi, libva-egl.
  • provide other improvement, e.g. use portable type to define data structure.

All packages using Package-x-generic-16.pnglibva will be rebuilt to take into account the new API/ABI. Futhermore, the intel backend will be updated along (not provided by Fedora). Others VA-API backend such the AMD and NVIDIA backend provided by Fedora within Package-x-generic-16.pngmesa-dri-drivers will work as appropriate. Bridges between VA-API and VDPAU will continue to be supported , this is:

  • Package-x-generic-16.pnglibva-vdpau-driver which allows to use the VA-API enabled players with VDPAU backend (such as NVIDIA binary driver).
  • Package-x-generic-16.pnglibvdpau-va-gl which allows to use the VDPAU API enabled players with VA-API backends (such as intel driver).

Benefit to Fedora

Fedora will provide a better multimedia experience on recent hardware.

Scope

  • Proposal owners:

Update and rebuild packages that depend on Package-x-generic-16.pnglibva. DONE

Verify that everything is working as appropriate or report issue upstream. TESTING IN PROGRESS.

Upgrade/compatibility impact

Users should update to the more recent version provided in repositories.

How To Test

  • Hardware that are fully supported in Fedora:

AMD with Package-x-generic-16.pngmesa-dri-drivers installed

  • Hardware that are fully supported in Fedora, but requires additional firmware

NVIDIA with Package-x-generic-16.pngmesa-dri-drivers installed and nouveau video firmware extracted from the NVIDIA binary driver.

  • Hardware that requires package provided by third party repository.

Intel HD graphics hardwares require a separate libva-intel-driver package that need to be installed. This VA-API backend can be downloaded from a single purpose f28-free-drivers repository provided by the RPM Fusion project.

1. vainfo should output the VA-API backend capabilities

2. totem with Package-x-generic-16.pnggstreamer1-vaapi installed should play the video with less CPU usage than when VAAPI backend is disabled.

User Experience

Users use less CPU resources when playing certain videos with VA-API enabled players.

Contingency Plan

  • If a Fedora application trigger any un-acceptable regression with VA-API, this application will be built with VA-API support disabled until the VA-API support can be restored.
  • Contingency mechanism:
  • Contingency deadline: N/A (not a System Wide Change)
  • Blocks release? N/A
  • Blocks product? None
