• 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")
  
                  }
  
              }
  
          }
  
      }
  
      android {
  
          compileSdkVersion = 24
  
          buildToolsVersion = "23.0.3"
  
  
  
          defaultConfig {
  
              minSdkVersion.apiLevel = 15
  
              targetSdkVersion.apiLevel = 24
  
              versionCode = 1
  
              versionName = "1.0"
  
          }
  
  
  
          ndk{
  
              //platformVersion = 21
  
              moduleName = "library-jni"
  
              stl = 'gnustl_static'
  
              toolchain = "clang"
  
              abiFilters.addAll(['armeabi', 'armeabi-v7a', 'arm64-v8a', 'mips'])
  
              cppFlags.addAll(['-std=c++11', '-D__STDC_CONSTANT_MACROS'])
  
              ldLibs.addAll(['log', 'android', 'z', 'EGL', 'GLESv2'])
  
          }
  
  
  
          sources {
  
              main {
  
                  jni {
  
                      source{
  
                          srcDirs 'src/main/jni'
  
                      }
  
                      dependencies {
  
                          library 'ffmpeg' linkage 'shared'
  
                      }
  
                  }
  
              }
  
          }
  
      }
  
  }

  I am getting an error :

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

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

• Processing files and then re-uploading with fog and carrierwave fails on production

  2 mars 2015, par Laurie

  So I’m trying to get use carrierwave and fog to upload a file to my server, processing that file using ffmpeg to cut it into multiple small files, then upload those to s3.

  This works locally (no fog, just file storage), but breaks on production with this error :

  NoMethodError: undefined method 'to_file' for #CarrierWave::Storage::Fog::File:0x0000000639a458>

  And this trace :

  /var/deploy/webapp/web_head/shared/bundle/ruby/2.2.0/gems/carrierwave-0.10.0/lib/carrierwave/storage/fog.rb 259:in `store'

  …/2.2.0/gems/rack-1.6.0/lib/rack/session/abstract/id.rb: 220:in `call'

  So, I have two uploaders. The uploader for the small chopped up audio files just sets the storage to fog, that’s it.

  After uploading the big audio file I run this processing function in the uploader (though the error doesn’t seem to come from here) :

  def split
  
    directory = File.dirname(current_path)
  
    tmpfile = File.join(directory,'tmpfile.mp3')
  
    File.rename(current_path,tmpfile)
  
    File.chmod(0644,tmpfile)
  
  
  
    sound = FFMPEG::Movie.new(tmpfile)
  
    @model.length = Mp3Info.open(tmpfile).length.round
  
  
  
  
  
    i=0
  
    number_of_lines= @model.ordered_lines.length
  
    lines = @model.ordered_lines
  
    while icode>

  Any ideas ?

• How to install opencv_contrib on Windows ?

  6 mai 2017, par How to code

  I want to use the function createFisherFaceRecognizer() in python,but when I wrote down model = cv2.createFisherFaceRecognizer() or cv2.face.createFisherFaceRecognizer()
  Error will occurs :

  Traceback (most recent call last) :
  File "C :\Users\Administrator\Desktop\My projects\test\RecognizeMe.py", line 5, in
  model = cv2.face.createFisherFaceRecognizer()
  AttributeError : ’module’ object has no attribute ’face’

  I referenced the methods online and found that I should install opencv_contrib.But I was stucked when I was configureing the opencv using CMake.
