Answers.Body: <p>The included x264 cli app may depend on libavformat and libswscale, which is where the ffmpeg dependency comes in.</p>
  <p>The libx264 wrapper in libavcodec depends on x264.</p>

Title: Compiling x264 in MinGW
UserDisplayName: Elliott B
ThreadText: # Compiling x264 in MinGW
  
  (Asked by: username_0 on 2021-01-17)
  
  I'm trying to do a minimal build of ffmpeg in MinGW including x264. For some reason the x264 package depends on ffms2 which depends on ffmpeg which itself has a huge list of dependencies. I will try installing x264 from git instead, but I'm wondering why pacman has this circular dependency loop.
