合并多个视频

过程师史，下面这个命令行直接挂掉，那里有问题？谢谢！

ffmpeg -i /storage/1477701680016.mp4 -i /storage/201628184254.mp4 -filter_complex ' concat=n=2:v=1:a=1 ' -map '' -map '' /storage/201630222338.mp4

合并不同编码的视频文件，我的语法哪里有问题，过程师兄弟给个例子，谢谢！

孙悟空 发表于 2016-10-31 09:39:33

不同编码的话，最好改成相同编码然后合并

小鱼 发表于 2016-10-31 09:51:16

感谢大师兄弟， 那就得搜索一下每个视频的编码方式， 然后全部转码成最长的那个视频的编码， 再合并。

另外，我就照着下面的语言写的，
https://ffmpeg.org/ffmpeg-filters.html#Examples-99

怎么老说我各种错误？ 能帮我写一个能运行的例子吗？
Invalid stream specifier: ''.
Invalid stream specifier: ''.
Invalid stream specifier: ''.

孙悟空 发表于 2016-10-31 10:22:11

转码后，直接用concat的format应该就可以咯
