Eu preciso dividir os arquivos de vídeo e, ao mesmo tempo, convertê-los em mp4 para um site. Eu tenho problemas para dividir arquivos AVI (flv e mp4 funcionaram bem).
Exemplo:
> ffmpeg -i original-1.avi -ss 00:03:00 -t 00:00:20 -acodec copy -vcodec libx264 -vpre hq -s 416x240 -y 1.mp4
Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 25.00 (25/1)
Input #0, avi, from 'original-1.avi':

Sua pergunta não está clara e não tenho certeza se a saída do comando está completa.
Tente forçar um -r na frente da entrada.
Isto parece um problema de um arquivo de entrada e menos de ffmpeg.
Além disso, por que decodificar por 3 minutos antes do processamento?
Aqui está uma breve introdução se você não tiver certeza do que seu comando está realmente fazendo aqui.
