Android中的JavaCV

Question

我下載了JavaCV-1-3-1。

現在我有2個問題：

1. 如何導入JavaCV到Android Studio中使用？

2. 可以從FFMPEG命令與JavaCV一起使用嗎？

Answer 1

要導入的Java簡歷內容添加到搖籃

dependencies { 
     compile 'org.bytedeco:javacv:+' 
compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-x86' 
compile 'org.bytedeco.javacpp-presets:ffmpeg:2.8.1-1.1:android-x86' 
compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-arm' 
compile 'org.bytedeco.javacpp-presets:ffmpeg:2.8.1-1.1:android-arm' 
    } 

Answer 2

您還可以使用WritingMindslibrary。這很容易實現。

依賴

compile 'com.writingminds:FFmpegAndroid:0.3.2'

可以使用的execute（）

示例代碼

final FFmpeg ffmpeg = FFmpeg.getInstance(activity); 
     try { 
      ffmpeg.loadBinary(new LoadBinaryResponseHandler() { 

       @Override 
       public void onStart() {} 
       @Override 
       public void onFailure() {} 
       @Override 
       public void onSuccess() { 

         String cropParams = "720:754:0:172"; 

         String[] cmd = {"-i" 
           , originalPath 
           , "-vf" 
           ,cropParams 
           ,"-threads" 
           ,"5" 
           ,"-preset" 
           ,"ultrafast" 
           ,croppedPath}; 
         // Execute cropping of video 
         ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() { 
          @Override 
          public void onStart() { 
          } 
          @Override 
          public void onProgress(String message) { 
           Log.i("Square", "progress : " +message); 
          } 
          @Override 
          public void onFailure(String message) { 
           Log.i("Square", "total fail : " + message); 
          } 
          @Override 
          public void onSuccess(String message) { 
           Log.i("Square", "Cropped video created."); 

          } 
          @Override 
          public void onFinish() { 

          } 
         }); 
        } catch (FFmpegCommandAlreadyRunningException e) { 
         // Handle if FFmpeg is already running 
        } 
       } 
      }); 
     } catch (FFmpegNotSupportedException e) { 
      // Handle if FFmpeg is not supported by device 
     }
