configure: fix compilation with glslang 14 
The configure check already had fallback for the previous version
of glslang, which had different requirements for flags.
This commit simply moves the flags needed for glslang 13 to the
fallback, while first trying to use new flags for glslang 14.

This drops support for ~3 year old glslang versions, which
I'm not sure had the complete C API we're using anyway.

  • 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.
