  • Constructor Details

    • FFMpegWrapper

      public FFMpegWrapper(File file)
      Creates a wrapper to run ffmpeg for the given video file. Will run ffmpeg in the current working directory of JVM.
      Parameters:
      file - video file to call ffmpeg with

    • FFMpegWrapper

      public FFMpegWrapper(File file, File workingDir)
      Creates a wrapper to run ffmpeg for the given video file. Provide a different workingDir every time you create this FFMpegWrapper as ffmpeg's temp file name in 2-pass encoding is hard coded in the ffmpeg build, which causes problem while running simultaneous multiple encodings. Even you use -passlogfile option, x264_2pass.log file name is hard coded in the older ffmpeg builds. For more details please refer to bug:42346.
      Parameters:
      file - video file to call ffmpeg with
      workingDir - a working directory for ffmpeg; if null, the current working directory of the JVM is used
