formato de pixel depreciado usado, verifique se você definiu o intervalo corretamente

Question

Por que recebo este aviso e como corrigi-lo? Essencialmente, quero converter um vídeo para um jpg a cada quatro quadros com a mesma resolução do vídeo original.

[jalal@goku vid2]$ ffmpeg -i debate_vid2.mov -r 0.25 images_%08d.jpg

Isso é apenas um aviso, não um erro. Você pode seguramente ignorá-lo.

PS: Sua versão do ffmpeg está desatualizada - tem quase dois anos. Não vai doer para atualizar para um novo.
