• C++/CLI — 0xc000007b (INVALID_IMAGE_FORMAT) with /clr option on

  9 mars 2015, par OverMachoGrande

  I’m trying to build a C++/CLI executable to which I statically link ffmpeg (libavcodec, libavformat, libavutil & swscale). It works fine if I build it normally (without /clr, so no CLR support), it works. However, when I add CLR support, it won’t start up with a 0xc000007b. A "Hello World" C++/CLI app runs fine, though.

  Supposedly the same thing happens with Boost::Threads, but since ffmpeg is pure C, I doubt it’s using Boost.

  My config :

  • Visual Studio 2008 Professional SP1
  • Windows XP Pro SP3 (x86)
  • .NET Framework 3.5 SP1

  Thanks,
  Robert

• How do I use native C libraries in Android Studio

  11 mars 2015, par Nicholas

  I created a problem some years back based on https://ikaruga2.wordpress.com/2011/06/15/video-live-wallpaper-part-1/. My project was built in the version of Eclipse provided directly by Google at the time and worked fine with a copy of the compiled ffmpeg libraries created with my app name.

  Now I’m trying to create a new app based on my old app. As Google no longer supports Eclipse I downloaded Android Studio and imported my project. With a few tweaks, I was able to successfully compile the old version of the project. So I modified the name, copied a new set of ".so" files into app\src\main\jniLibs\armeabi (where I assumed they should go) and tried running the application on my phone again with absolutely no other changes.

  The NDK throws no errors. Gradle compiles the file without errors and installs it on my phone. The app appears in my live wallpapers list and I can click it to bring up the preview. But instead of a video appearing I receive and error and logCat reports :

  I’m a novice Android/Java/C++ developer and am not sure what this error means, but Google leads me to believe that my new libraries are not being found. In my Eclipse project I had this set of libraries in "libs\armeabi", and another copy of them in a more complicated folder structure at "jni\ffmpeg-android\build\ffmpeg\armeabi\lib". Android Studio appears to have kept everything the same, other than renaming "libs" to "jniLibs", but I’m hitting a brick wall with this error and am unsure how to proceed.

  How can I compile this new app with the new name using Android Studio ?

  In case it helps here is my Android.mk file :

• Build FFMPEG on MAC with my own license

  16 février 2015, par Ashish

  I am new in ffmpeg world. I want to build the ffmpeg exe on MAC os using its binary source. I have tried to build the exe and infact i succeeded in compiling exe but when i run that exe i got this line :

  ffmpeg version 2.2.4 Copyright (c) 2000-2014 the FFmpeg developers

  While surfing on internet i got an exe with different copyright holder. I also want to change that "the FFmpeg developer" with with my name. Please help me out how to do this ?
  Thanks.
