I just found out that when using this command in a batch file, it 
doesn't matter if the slashes are forward or backward. But when the 
command is typed into the console window (without the ^ character), then 
it works only if backslashes are used. And then piping from ffmpeg to 
ffplay works fine!
Why doesn't the same command line work in a batch file? What must I change?
