Codemasters

As far as I know, Codemasters themselves did not have a video policy. However, now that they have been acquired by EA, the video policy should be the same as EA's.

I will make a note that, as is the case with all other racing games, any models of real cars, music in a game's soundtrack, and games based on other franchised proterties such as Fast & Furious, all have their own rights and licenses. In many cases, even if the publisher allows for it, you might not be able to monetize or even stream or create videos for these games without risk of claims and take-downs.

From EA's FAQ:

"EA does not object to fair uses of video footage or screenshots on video sharing sites, including YouTube channels that are commercialized, as long as the footage is a version of the game that we have released to the public."

"because many EA games include content that is licensed from a third-party company or may otherwise have usage restrictions"

There are no explicit rules against streaming only for paid subscribers on Twitch.
