## Usage

`movie-barcode.sh [PATH_TO_MOVIE] [FRAMES_TO_EXRACT=2000]`
`./movie-barcode [PATH_TO_MOVIE] [FRAMES_TO_EXRACT=2000] [OUTPUT_FILENAME=$MOVIE_BASENAME]`

## Sample

**Movie: Scarface (1983)**

`movie-barcode.sh "$HOME/Movies/Scarface (1983).mp4" 2000`
`./movie-barcode "$HOME/Movies/Scarface (1983).mp4" 2000`

![Movie Barcode of Scarface](https://raw.githubusercontent.com/tyler-king/movie-barcode/master/samples/scarface.jpg)

Would output a file named `Scarface_(1983).mp4.jpg` in the same directory as the movie-barcode executable.

**Music: DMX - I Don't Dance**

`movie-barcode.sh "$HOME/Downloads/DMX - I Dont Dance.mp4" 2000`
`movie-barcode.sh "$HOME/Downloads/DMX - I Dont Dance.mp4" 2000 i_dont_dance.jpg`

![Movie Barcode of DMX](https://raw.githubusercontent.com/tyler-king/movie-barcode/master/samples/dmx.jpg)

Would output a file named `i_dont_dance.jpg` in the same directory as the movie-barcode executable.
