Making the bots work hard today, I see!
IMO, this change could be included in https://codereview.webrtc.org/2248373002/
- once the backwards compatible CreateFilePlayer can be removed, the new variant
could as well step in immediately. None of the changes are very large either.

Yes, technically it could, but I prefer small commits that do just one thing.
It's easier to read and review that way, and you really appreciate it if you end
up having to revert.

Yeah but there's small and there's tiny. :)
I'm not going to insist on it. This CL LGTM.
