我已经编写了基于cygwin的shell脚本来连接2个.mkv文件，如下所示，
#!/bin/sh
ffmpeg -f concat -i concat.txt -codec copy out.mkv
concat.txt包含要连接的2个mkv文件的路径
file '../temp/1'
file '../temp/2'
当我从cygwin终端运行脚本时出现以下错误

'NULL @ 04780280] Unable to find a suitable output format for 'out.mkv

另外要补充一点，如果我直接从cygwin终端运行此命令（而不是通过脚本调用它），它会正确运行并创建连续输出.mkv文件
答案 0 :(得分：0)
在shell脚本文件中应用 dos2unix 命令解决了我的问题。希望它可以帮到某人。
