For single frames in photoshop it is possible with content-aware-fill
I just tried it and (depending on the source material) it works great:

However if you did it to all the frames of the scene it apparently wouldn’t look that good because there would be inconsistencies between the frames

For video I have seen attempts to blur it out. Mostly for blurrying the logos of tv-channels and so on. This works somewhat but the corners in the place where the logo would have been mostly look a bit warped

But I guess this blurrying is your only option for now (besides cropping)

Apparently adobe is planning to bring some kind of content-aware fill for video to after effects (called project cloak) but I believe that is not available yet
