Aleksoid 336d59643a avcodec/d3d12va_vc1: add support for D3D12_VIDEO_DECODE_PROFILE_VC1_D2010 guid. 
The VC1_D2010 profile, also known as VC1_VLD2010, has the same functionality
and specification as the VC1_D profile. Support for this profile serves only
as a positive indication that the accelerator has been designed with awareness
of the modifications specified in the August 2010 version of this specification.

Hardware accelerator drivers that expose support for this profile must not
also expose the previously specified VC1_D GUID, unless the accelerator works
properly with existing software decoders that use VC1_D and that do not incorporate
the corrections added to the August 2010 version of this specification.

As a result, we could give VC1_VLD2010 a higher priority and initialize
it first.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
