Usage

Instantiate your video file:

movie = Jwthumbs::Movie.new("YOUR_VIDEO.mp4")

Jwthumbs::Movie.new accepts second parameter as a options hash. You can configure several stuff at the same time you instantiate your video like this:

movie = Jwthumbs::Movie.new("YOUR_VIDEO.mp4", seconds_between: 60, sprite_name: "my_sprite_name.jpg")

or after you instentiated your video, you can use Jwthumbs::Movie file to configure things:

movie = Jwthumbs::Movie.new("YOUR_VIDEO.mp4")
movie.seconds_between = 60
movie.sprite_name = "my_sprite_name.jpg"

and then to create your thumbnails and .VTT file just run this command.

movie.create_thumbs!
