Process.start err #4

參考了這個文章

File fileBinDir = new File(activity.getFilesDir().getParentFile(), "lib"); //FFmpeg執行檔的所在目錄
File fileBin = new File(fileBinDir, "libffmpeg.so"); //FFmpeg執行檔的檔案路徑
ProcessBuilder pb = new ProcessBuilder(cmds); //cmds為Command Line的指令，例如某行指令為：「libffmpeg.so　-h」cmds的List內容就是["libffmpeg.so","-h"]
pb.directory(fileBinDir); //將工作目錄移到FFmpeg執行檔的所在目錄，不過還是建議在cmds中以絕對路徑來表示libffmpeg.so
pb.redirectErrorStream(true); //將FFmpeg的標準輸出和錯誤輸出合併成同一個inputStream
Process process = pb.start(); //執行行程

不知道為何在執行

pb.start();

時候報錯. 錯誤信息如下:
