Eu tenho alguns vídeos caseiros em VideoCDs e gostaria de transferir para o YouTube para que eu possa compartilhá-los com a família. Eu fiz backup das imagens de CD na minha unidade com dd e reproduzi essas imagens com mplayer funcionando bem.

mplayer nos informa que alguns quadros estão corrompidos, mas ainda é possível reproduzi-lo bem.
Agora, quero usar o ffmpeg para convertê-lo em algo que possa ser enviado de forma ideal para o YouTube, mas isso falha.

Pelo que entendi, ele olha para a extensão (.bin) e para um único frame e não consegue realmente descobrir os parâmetros do codec.
Onde obtenho todos os parâmetros de codec necessários e como especificá-los?
