• What is this "fixing the build scripts" for compiling x264 ?

  29 mai 2020, par Blake Senftner

  I am trying to compile an all static build of source-customized ffmpeg libraries with the additional codecs from VideoLAN, such as their x264 codec. I am ultimately building for use in Windows with Visual Studio 2015 C++, so I am comparing a few compiling guides for my instructions.

  



  In the guide linked below (I located via Google searches) shows how to compile x264 with the VS2015 toolchain in MSYS2 without any special steps :
https://gist.github.com/RangelReale/3e6392289d8ba1a52b6e70cdd7e10282

  



  While in this other guide, offered by the compiling guide pages from ffmpeg's web site, it includes steps for "fixing the build scripts" for x264 :
https://www.roxlu.com/2019/062/compiling-ffmpeg-with-x264-on-windows-10-using-msvc

  



  Problem being, when I "fix the build scripts" the configure script no longer finds a C compiler. Building with the first guide seems to work, but it was also written nearly 2 years ago, so perhaps the ffmpeg guide is doing some important fix ? I don't know.

  



  I am :

  



  

  1. Running a "VS2015 x64 Native Tools Command Prompt"

  


  2. launching a pacman loaded msys2 shell via "msys2_shell.cmd -mingw64 -use-full-path"

  


  3. git cloning http://git.videolan.org/git/x264.git

  


  



  and at this point the two compiling guides vary, the first guide just cd's into x264 and runs configure while the other guide does some curl download of a config.guess file and then some sed manipulation of ./configure. Considering these instructions are "endorsed" by the ffmpeg site, I am left wondering what that is doing and how critical is it that these "special" steps cause my x264 configure to fail.

  


• Stackposts ffmpeg error (Instagram videos)

  30 décembre 2023, par starneybinson

  I am trying to post Instagram Reels via Stackposts (Ubuntu/nginx) but I am facing this error message :

  


  For sharing videos on Instagram, you have to install the FFmpeg library on your server and configure executables path.

  


  error message

  


  I have ffmpeg installed but it still won't work :

  Does anyone have an idea on how to fix this ?

  


  I have tried to modify the file permissions of the library located in /bin/ffmpeg for the nginx user (www) and I have tried to move the binary to the location of the Stackposts installation.
