Niklas Haas 098b338369 lavfi/vf_libplacebo: require v5.278 for importing 
Importing Vulkan device on older versions no longer works due to the
lavu vulkan API changes (specifically, the switch to planar textures by
default). Additionally, importing on versions that don't suppirt
lock/unlock_queue is unsafe with the advent of the threaded vulkan
hwaccel. As a plus, saves us some annoying #ifdef boilerplate.

I will raise the minimum vf_libplacebo version globally on the next
stable release of libplacebo, and remove all of these checks.

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.
