Lynne 59707cc485 hwcontext_vulkan: initialize and require instance version 1.3 
This just bumps the required loader library version (libvulkan).
All device-related features, such as video decoding, atomics, etc.
are still optional and the code deals with their loss on a local level
(e.g. the decoder or filter checks for the features it needs, not
the hwcontext).

Bumping the required version essentially packs all maintenance
extensions which correct the spec rather than requiring to enable
them individually.

  • 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.
