如何使用ffmpeg合并两个avi文件？ [英] Howto merge two avi files using ffmpeg?

问题描述

我无法将两个AVI视频合并在一起。
谷歌充满了以下例子：

I'm unable to merge two avi videos together. google is full of below examples:

cat file1.avi file2.avi file3.avi > video_draft.avi
after appending the data together using cat above, you need to re-index the draft movie like this:

mencoder video_draft.avi -o video_final.avi -forceidx -ovc copy -oac copy
Now you're video_final.avi file will be right to go.

但它对我来说不起作用，第一个视频被转换，就是这样。 >

but it doesn't work for me, the first video is converted and that's it.

推荐答案

您应该查看 concat demux和concat协议。假设编解码器是相同的，您创建一个文件（例如 mylist.txt ）：

You should look into the concat demux and concat protocol that was added in ffmpeg 1.1. Assuming the codecs are the same you create a file (example mylist.txt):

file '/path/here/file1.avi'
file '/path/here/file2.avi'
file '/path/here/file3.avi'

然后将该文件传递给ffmpeg

Then pass that file to ffmpeg

ffmpeg -f concat -i mylist.txt -c copy video_draft.avi

你可以使用此命令列出：

You can use this command to make the list:

ls *.avi | while read each; do echo "file '$each'" >> mylist.txt; done
