})

API

#create()

create: function (file, options, callback)

Creates a .png image thumbnail of the provided file.

• Parameters
  • file (String) - Absolute path to the video file
  • options (Object)
    • folder (String) - Directory to place the thumbnails (Default: Directory of file)
    • size (Number) - Maximum width of the generated images in pixels (Default: 512)
  • callback (Function) - Called with result when process terminates
    • error (Error)
    • path (String) - Absolute path to generated image

Limitations

This module can only generate thumbnails for files supported by the Apple OS X Quick Look framework. Only PNG is supported as output image format.

Apart from h264 video files in mp4 containers (and many other media files) a multitude of document formats is supported out of the box.

For a list of all supported filetypes, please feel free to refer to Wikipedia.
