Kacper Michajłow 47c6af7d29 avutil/avassert: always implement av_assume with av_unreachable 
One of the design goals of this macro is the ability to support static
inline predicate functions. Which is emitting warning in clang that a
function may have side-effects and the condition will be ignored. MSVC
doesn't emit warning, but also ignore predicate in such cases.

Instead of using assume builtins, implement it using unreachable. Which
solves this case for MSVC and Clang.

This reverts ea56fe60ac, but also extends
it to MSVC, which is affected in the similar way.

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.
