• compiling ffmpeg and chromaprint for android with success on some devices

  4 août 2016, par D Liebman

  I am following the recommendations of this site :

  https://bitbucket.org/phorton1/chromaprint

  From the site I have copied the multi-configure and multi-make scripts for the ffmpeg and chromaprint libraries. I have used them with recent clones of ffmpeg 3.0 and chromaprint 1.3.2 . I get working ’.so’ files for arm, x86 and armv7. I don’t have compillation problems. I load them into my app (a very simple app just to test this library) and I try it on my two devices. One is a Samsung Galaxy TabPro (SM-T320, api 19), and one is the Samsung S4 (api 21). I get the program to run on both. I can use the ’-version’ command to get the chromaprint version info. When I try to fingerprint a audio file, the software works on the older tablet, but not on the s4. On the s4 the error message is ’error decoding audio’.

  I have tried ffmpeg 0.9 as the bitbucket site suggests. I have the same problem. I have tried ffmpeg 2.7 and I thought this was working. Now I cannot get 2.7 to work. As before the code works on the api 19 device and not the s4.

  The Tab is an armeabi-v7a device and the s4 is an armeabi/armeabi-v7 device, so I thought by removing the ’armeabi’ binary I would have the same file on both machines, and they would have to work. This attempt did nothing. I am using android studio.

  Below is a list of some of my ffmpeg configurations. They are taken from the multi-configure script.

  EDIT :

  This is the complete source for my project minus the api-key which is personal. https://github.com/radiodee1/awesome-fpcalc The code is arranged in parts inside the git repository. The ’fpcalc-testapp’ part just has the Android Studio project. The ’fpcalc-build’ part is my attempt to use the latest versions of ffmpeg, chromaprint, and kissfft. The ’fpcalc-build-complete’ part is a series of scripts that reproduces the P. Horton ffmpeg 2.7 scenario. Bye the way I believe the best libraries are produced in the ’build-complete’ folders.

• Error:No such property : targetPlatform for class : com.android.build.gradle.managed.NdkConfig

  30 juillet 2016, par Alder

  I am trying to build FFMPEG into my JNI code with gradle in Android Studio. I have build FFMPEG as a .so file, in order to adapt different platform, I build it for different ABI(arm64-v8a, armeabi-v7a, mip, etc).Then I need to determine the ABI of the current build in the build.gradle file.

  Refer Experimental Plugin User Guide, my build.gradle look like this :

  apply plugin: 'com.android.model.native'    
  
  model{
  
      repositories {
  
          prebuilt(PrebuiltLibraries){
  
              ffmpeg{
  
                  headers.srcDir "src/main/jni/build/${targetPlatform.getName()}/include"
  
                  binaries.withType(SharedLibraryBinary) {
  
                      sharedLibraryFile = file("src/main/jni/build/${targetPlatform.getName()}/libvflibrary.so")
  
                  }
  
              }
  
          }

              targetSdkVersion.apiLevel = 24
  
              versionCode = 1
  
              versionName = "1.0"
  
          }
  
  
  
          ndk{
  
              //platformVersion = 21
  
              moduleName = "library-jni"

  }

  I am getting an error :

  Does anyone have an idea on how I can solve this, please ?
