当我想使用以下命令转换视频时:
ffmpeg -i file.wmv -sameq file.mpg
它以以下错误消息结束:

Seems stream 1 codec frame rate differs from container frame rate:
1000.00 (1000/1) -> 30.00 (30/1) Input #0, asf, from 'file.wmv': Duration: 00:16:53.68, start: 3.065000, bitrate: 3827 kb/s

Stream #0.1: Video: wmv3, yuv420p, 1920x1080, 3750 kb/s, 30 tbr, 1k tbn, 1k tbc Could not open 'file.mpg'
怎么了?我该如何修复它?
