Niklas HaasandClaude Opus 5.5 4e3adb4225 swscale/x86: use NASM uop macros generated by uops_macros_gen
Replaces the hack of running the C preprocessor over the C macros to produce
NASM syntax at build time. The generated file is now committed and checked by
FATE, as with uops_macros.h.

As a side effect, the DECL_* macros are now proper multi-line NASM macros,
so drop the parentheses around their arguments.

The FATE test is split up per generated file, with fate-sws-uops-macros
running all of them.

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.
