Overview

This is a perl script wrapper for video format conversion using ffmpeg. This helps to convert video formats without specifying complecated options.

Conditions

1. Perl must need to run on a command line
2. Need ffmepg rev11870. For Windows, You can download it from ffmpeg.zip(3MB)(Modified program name to ffmpeg.r11870.exe just for convenience), or http://ffdshow.faireal.net/mirror/ffmpeg.

Usage

 vconvert.pl [options] <video file> [<video files> ...]

As arguments, multiple input files you want to convert from can be specified with options. The options can be the follows;

    --help : Display this message
    --size <WxH> : Output video size, e.g. 320x240, 320x180, ....
                   Default : the same size as original input file
    --aspect <ratio> : Aspect ratio, e.g. 4:3, 16:9, 1.7777, .....
                       Default : the same aspect ratio as original input file
    --target <format> : Target video format, e.g. mp4, avi, wmv, flv, mp3, swf
                        Default : mp4
                        When mp3 is specified, only audio is extracted.

The following format conversions have been confirmed by this script. Basically all formats ffmepg supports can be handled by the script. So do the output formats.

  flv -> avi
  flv -> mp4
  flv -> wmv
  flv -> swf
  avi -> mp4
  avi -> wmv
  avi -> flv
