Duração incorreta para arquivos MOV H.264

Question

Estamos usando o ffmpeg para obter os metadados dos arquivos de vídeo.

Para arquivos MOV H.264, o ffmpeg está incorretamente dando a duração de 00:05:34, enquanto a duração real do arquivo de vídeo é 00:00:30. É reproduzível com qualquer vídeo deste formato.

Estou usando o ffmpeg-0.6.6.

Exemplo de saída:

ffmpeg -i ~/FINAL_WOMENS_WEB_FALL13.mov

Seems stream 1 codec frame rate differs from container frame rate: 5994.00 (5994/1) -> 23.98 (2997/125)
