No, the patch submitter (implicitly) does. Which is not a problem when 
the copyright holder and submitter are the same person. For sponsored 
code, they may not be.


Scenario 1

A 'vlogger' makes a video and uploads it as public to Youtube. Youtube 
then lets everyone see that video. No problem.

Scenario 2

Someone pays the vlogger to make a video. Vlogger uploads it to YT as 
public. There's a problem if the client did not allow that which makes 
it copyright infringement, Which is why YT has this clause in their T&C

"You affirm, represent, and warrant that you own or have the necessary 
licenses, rights, consents, and permissions to publish Content you 
submit; and you license to YouTube all patent, trademark, trade secret, 
copyright or other proprietary rights in and to such Content for 
publication on the Service pursuant to these Terms of Service."

So, we are YT in this case and the Content is the patch(es). The concern 
would be that the submitter doesn't have the right to license the code 
into ffmpeg, if the contract with the client doesn't allow them to do 
it. Only way to be sure is for the sponsor to affirm to it. And for 
that, we would have to know that there is a sponsor, to start with.
