Eaew pessoal eh o seguinte instalei o ffmpeg no kurumin NG, e quando eu vou converter um video .flv pra qualquer formato ele cria o arquivo convertido mas esse arquivo fica vazi, como exemplo uso o seguinte comando

sudo ffmpeg -i Video.flv arquivo.mp3

ai com isso fica vazio o arquivo criado

flowww !!!!

Amigo, a utilização correta do ffmpeg seria assim:

ffmpeg -i Video.flv arquivo.mp3

Não esqueça de acrescentar o "-i" que informa o arquivo de entrada, se não for passado esse parâmetro, realmente sua conversão não funcionará.

quando voce usa o sudo antes do comando voce esta fazendo o arquivo pertencer ao root e como o usuario comun nao e root ele nao pode ler o mp3

sudo ffmpeg -i Video.flv arquivo.mp3 = arquivo so pode ser lido pelo root
ffmpeg -i Video.flv arquivo.mp3 = arquivo pode ser lido pelo usuario comun

outra alternativa para nao perder tempo caso o arquivo seja grande ou uma grande quantidade de arquivos foram convertidas e voce nao quer converter tudo denovo, digite no terminal

sudo chown usuario *.mp3 = esse comando esta mudando o dono do arquivos de mp3 para o usuario, substitua a palavra usuario com o seu nome de usuario, exemplo no meu caso

sudo chown mauricio *.mp3
