如何连接一个 wav 文件列表？
How to concatenate a list of wav files?
我在 file.txt
中有一个 wav 文件列表
1.wav
2.wav
...
我使用下面的命令来执行操作。
ffmpeg -f concat -safe 0 -i file.txt -c copy output.wav
不过我得到
[concat @ 0x5574a8046900] Line 1: unknown keyword 1.wav: Invalid data found when processing input
为什么这不起作用？
如果你的 .wav 文件不包含空格等特殊字符，你可以这样做:
files=(1.wav 2.wav ...)
ffmpeg -f concat -safe 0 ${files[@]/#/-i } -c copy output.wav
Based on this wiki page，你需要修改你的file.txt如下：
file '1.wav'
file '2.wav'
# ... etc
命令本身应该可以正常工作。
页面摘录：

This demuxer reads a list of files and other directives from a text file and demuxes them one after the other, as if all their packets had been muxed together.
...
Instructions
Create a file mylist.txt with all the files you want to have concatenated in the following form (lines starting with a # are ignored):
# this is a comment
file '/path/to/file1.wav'
file '/path/to/file2.wav'
file '/path/to/file3.wav'
