任何想法在这里出了什么问题？在这种情况下，术语不安全文件是什么意思？

Any ideas what goes wrong here? What does the term "unsafe file" mean in this context?

推荐答案

@Mulvya表示的答案（谢谢！）有效：在 -i 之前添加-安全0 。
然后另一个问题出现在 find STREAM -name'*'-printf file'$ PWD /％p'\n 中，该空路径返回为第一次进入。将./*.wav中的f更改为；回显文件'$ PWD / $ f'；完成（请参见 https://trac.ffmpeg.org/wiki/Concatenate），现在看来可以了。哇！

The answer stated by @Mulvya (thank you!) works: "Add -safe 0 before -i". Then another problem appeared with find STREAM -name '*' -printf "file '$PWD/%p'\n" which returns the empty path as first entry. Changed this for for f in ./*.wav; do echo "file '$PWD/$f'"; done (see https://trac.ffmpeg.org/wiki/Concatenate) and now it seems to work. Hurray!
