extends java.lang.Object

    • Constructor Detail

      • FFMpegWrapper

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

      • FFMpegWrapper

        public FFMpegWrapper​(java.io.File file,
                     java.io.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
