無法在Android中使用FFMPEG複製RTSP流式視頻

Question

我正在開發一個android應用程序。在我的應用程序中，我想要錄製實況流視頻使用ffmpeg library.I爲錄製實況流錄像寫入一個代碼，但它不起作用。它顯示了一些錯誤。如果有人知道這一點，請幫助我。

這是我用來記錄視頻

try { 

      fFmpeg.execute(new String[]{"ffmpeg -i rtsp://192.168.1.1:6667/streamhd -acodec copy -vcode c copy"+String.valueOf(getCacheDir())+"/MyVideo.mp4"}, new ExecuteBinaryResponseHandler() { 

       @Override 
       public void onSuccess(String message) { 
        Log.d("fffffff", "FFmpeg cmd success"); 
       } 

       @Override 
       public void onFailure(String message) { 
        Log.d("ffffffffffff", message.toString()); 
       } 
      }); 
     }catch (FFmpegCommandAlreadyRunningException e) { 
      // Handle if FFmpeg is already running 
      e.printStackTrace(); 
      Log.w(null,e.toString());} 

當我執行這一塊我得到以下錯誤信息代碼。

Answer 1

最後我建立了解決方案。在android中，您必須將FFMpeg.execute（）方法的參數作爲字符串數組傳遞。

使用下面的代碼

String[] cmd = {"-i" , "rtsp://192.168.1.1:6667/streamhd" , "-fs" , "25M" , "-b" , "900k" , "-vcodec" , "copy" , "-r" , "60" , "-y" ,"-movflags","+faststart",""+getNextFileName() } ; 

try { 

      fFmpeg.execute(cmd, new ExecuteBinaryResponseHandler() { 


       @Override 
       public void onSuccess(String message) { 
        Log.d("fffffff", "FFmpeg cmd success"); 
       } 

       @Override 
       public void onFailure(String message) { 
        Log.d("ffffffffffff", message.toString()); 
       } 
       @Override 
       public void onProgress(String message) { 
} 
       @Override 
       public void onFinish() { 
        Log.d("finish",""+fFmpeg.isFFmpegCommandRunning()); 

       } 

      }); 
     }catch (FFmpegCommandAlreadyRunningException e) { 
      // Handle if FFmpeg is already running 
      e.printStackTrace(); 
      Log.w(null,e.toString());}
