Martin Storsjö d1e37eb0cd avutil/mem_internal: Don't include stdalign.h on MSVC 
It's currently actually not used in MSVC builds, since
6e49b8699657b808b7dc80033f2c3f2d0e029fa3.

Older versions of MSVC (or, in particular, older versions of UCRT)
don't have stdalign.h; it's available since WinSDK 10.0.20348.0;
such a new enough version has been installed by default only since
MSVC 2022 17.4 and newer.

With this change, ffmpeg can still be built with MSVC 2019 16.8
(v19.28).

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.
