Recently I want to use the concat protocol to play multiple online videos,
I tried the command below:

ffplay -safe 0 -protocol_whitelist concat,file,subfile,http,https,tcp,tls

But it gives me an error:

Error when loading first segment 'concat:
Invalid data found when processing input

As the documentation said:

A URL accepted by this protocol has the syntax:


How do I deal with this problem? I have already known that there is a
workaround that I can use a ffconcat file but I really want to save the
string in the terminal, not in the file.

Looking forward to your reply.
