Video recording maybe possible but not really useful.
The video quality on co-pilot isn't the best, as it receives a repetition of the video the main TelloFpv app receives (which mean it has at least twice the interference). You can do screen recording on the Copilot device but as said, quality is OK for a secondary screen but not for recording.
Photo is not possible as that data isn't forwarded to copilot (that would overload the link).
