Here's a patch for this part:

https://github.com/ffstaging/FFmpeg/pull/34

https://github.com/ffstaging/FFmpeg/pull/34.patch

Can't send it right now because Google decided to no longer
username/password login (which affects ffmpegagent). It's
said to work with an "app password" which in turn can only
be used when 2step verification is set up, and that again
requires either a phone or a security key :-(

Does anybody know a "security key" emulator.
