nlmeans_vulkan: fix offsets calculation and various stride issues 
We calculated offsets as pairs, but addressed them in the shader
as single float values, while reading them as ivec2s.

Also removes unused code (was provisionally added if cooperative matrices
could be used, but that turned out to be impossible).

  • 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.
