• Building FFMPEGINTEROP with Visual Studio 2017 ?

  25 septembre 2018, par Francois Gagnon

  I’m working on a project that requires a video player. I’ve been using the standard UWP MediaPlayerElement but it refuses to read many types of videos, including ASF and FLV and some older MPG.

  I’ve read that ffmpeginterop is more compatible with a variety of codecs. However building it is a finicky and all the instructions are designed for VS2015 and command prompt for ARM processor, which does not exist for VS2017. I can’t find an updated version of the instructions (Left a message on their GIT site as well... no answers).

  So my question is two-fold :

  1. Is there any way to download the missing/updated codecs to include them in my project that uses the standard UWP approach ?

  2. Is there an updated way/tutorial/instructions of building ffmpeginterop with VS2017 ?

  3. Is ffmpeginterop too old and I should not build using it going forward ?

  Thanks !

• How set CMake to find a local package FFmpeg ?

  7 mai 2024, par zerpico

  I am trying write CMakeLists with FFmpeg package, with compile on Windows and Linux.
First downloaded from FFmpeg-Builds shared releases

  


  I imagine the structure of the project like this :

  


  <project root="root">&#xA;deps/&#xA;  ffmpeg/&#xA;    win-x64/&#xA;      incluve/&#xA;      lib/&#xA;      bin/&#xA;    linux-x64/&#xA;      incluve/&#xA;      lib/&#xA;      bin/&#xA;src/&#xA;CMakeLists.txt&#xA;</project>

  


  How to help CMake find libraries : avcodec, avformat, avutil, etc ?
Maybe in the folder lib/pkgconfig using PkgConfig it is possible to specify the path.
But I dont know how

  


• 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...
