Output Format not Parsed using Windows Batch File

[a6286224]

When running youtube-dl from a Windows batch file, the output format is not correctly parsed. Copying and pasting it from the file works fine.

-o "%(upload_date)s - %(uploader)s - %(title)s.%(ext)s"

results in files named

"(uploader)s - (ext)s"

You have to escape % in batch file.
youtube-dl -o "%%(upload_date)s - %%(uploader)s - %%(title)s.%%(ext)s" %1 works perfectly for me.
