Niklas Haas 143cb56501 swscale/vulkan/ops: use opaque run function 
Avoids some unnecessary round-trips through the execution harness, as well
as removing one unnecessary layer of abstraction (SwsOpExec).

It's a bit unfortunate that we have to cast away the const on the AVFrame,
since the Vulkan functions take non-const everywhere, even though all they're
doing is modifying frame internal metadata, but alas.

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.
