Question

I am trying to implement an extractor for Microsoft Stream, which requires users to log in to access any video. Is it possible to pass the username-password pair and/or the .netrc file to the extractor during development? I have tried the following:

1. Defining a .netrc file without the --netrc argument
2. Defining a _netrc file without the --netrc argument
3. Defining a .netrc file with the --netrc argument
4. Defining a _netrc file with the --netrc argument
5. Defining the credential with the --username and --password arguments

A workaround I can think of it to hard-code a testing credential in NewSiteIE._get_login_info() during development and remove it before pushing it GitHub. Am I missing something in the documentation?

I am developing the extractor on my Windows 10 laptop running Python 3.7.6, based on commit 049c048

Many thanks!
