COMO EXECUTAR:

Para executar o programa basta escrever no terminal:

# ./criaDVD <video1> <video2> ...

Onde <video1,2,...> é o nome do filme com o caminho. Ex.:

./criaDVD ~/video1.avi ./Outros/video2.avi

OPÇÕES:

-> config : Remove a configuração existente e cria uma nova configuração

DEPENDÊNCIAS:

- avidemux-cli
- avidemux-common
- tovid
- mencoder
- lame
- toolame
- mjpegtools
- imagemagick
- zenity
