很多人问这个问题,但每个问题的意思都不一样,我什么都不明白。
我正在尝试剪切视频并将更改保存到另一个文件:
ffmpeg -i C:\Users\danie\Videos\video4.mp4 -ss 1:00 -t 3:00 -vcodec copy -acodec copy video5.mp4
当我在 cmd 中输入此命令时,我得到以下行:
[NULL @ 000000000318f4c0] Unable to find a suitable output format for 'ffmpeg'
ffmpeg: Invalid argument
我不明白哪里出了问题。有人能帮我解决吗?
编辑:这是日志输出:

答案1
这个错误经常发生,因为命令错误。
似乎您的命令中还有一个ffmpeg
词ffmpeg
,如下所示:
C:\ffmpeg-20160428-git-78baa45-win64-static\bin\ffmpeg.exe ffmpeg -i ...
。
尝试删除它:
C:\ffmpeg-20160428-git-78baa45-win64-static\bin\ffmpeg.exe -i ...
。或者简单地ffmpeg -i ...
