  avformat/mov : Add support for exporting Video Extension Usage info
  This box is provided by files created by the Apple Vision Pro, as well
  
  as the iPhone 15+ when capture for Vision Pro is enabled.
  The boxes are a mix of things documented by Apple in some PDFs, their
  
  API docs, and reverse engineering. Ideally we will have a real spec
  
  one day.

• Compile FFMPEG for iOS development

  7 avril 2016, par Alec Gamble

  So I’ve been googling around and there seem to be a lot of answers to this questions... for people who know what they’re doing. Unfortunately I am not one of these people. I had a version of FFMPEG I was using in a project and now I want to port that project to iOS. So I have a version of FFMPEG with LAME installed on my desktop and in my C++ application I was just accessing this through the command line via the system() method. I also just downloaded the FFMPEG iOS build from here :

  https://github.com/kewlbear/FFmpeg-iOS-build-script

  and the gas-preprocessor from the link on that page but I’m unsure as to what to do with it now and how to get it to a state where I would be able to compile a basic FFMPEG test to my iPhone.

  ---

  I tried adding the libraries as mentioned in :
  How to Build FFMpeg as iOS Framework so my project hierarchy looks like :

  

  but when I do :

  #import <libavcodec></libavcodec>avcodec.h> as suggested

  or any other import I can think to do it always errors me out saying it can’t find it. I’m not sure if this is because I’m not using search paths correctly or my import line is wrong or what...

  Merge remote-tracking branch ’cehoyos/master’
  * cehoyos/master :
  
    Show max bitrate for mpeg2 video streams in avcodec_string().
  
    Allow native compilation on the iPhone.
