The only things I can recall being notified beforehand of no video recording and/or flash photography are Captain EO, Turtle Talk with Crush, and Muppet Vision 3D. Everything else that I can remember just says no flash photography.
I've thought about deploying the handle bar mount on quite a few rides. Ride a few times with two or three locked-off angles and edit into a complete ride-through. I think they might crush you if you tried this.
I've used my little point-and-shoot camera on Screamin' with no problems. I have it in my hand getting into the car, and nobody has said anything. I haven't tried taking video, the ride's too shaky, but I've taken some stills with no problems other than being terrible at framing the shot!
I pledge allegiance to the Earth, one planet, many gods, and to the universe in which she spins.
I've been told no photography at all on Captain EO even before the show started or sitting down. Seems anything that plays a movie or lengthy video prohibits any kind of video/photography due to copyright.
You can never run out of imagination. The more you use, the more you gain.
There is a channel on YouTube that posts POV videos from Disneyland and DCA and they have one on California Screamin' that used a GoPro mount and recorded the ride in reverse to show his face. He obviously was allowed to do that and mount a camera on the ride vehicle.
I hate when people use giant iPads and tablets. That's what I would tell people to put away if I was a CM. The second time I saw World of Color I watched it through the iPad the person in front of me blocked my view with.
Cameras on fast rides are a huge safety issue. I can't remember the roller coaster but on one a couple of years ago some poor dude lost an eye because someone lost their camera and it ended up hitting the guy in the face. So I can't imagine Disney with its safety policies would want people trying to use any camera on a fast ride like California scream'n... Just imagine if your Go Pro came loose on one of the hills so that it ended up crashing back into someone in a car behind you.
Whatever happened to just living in the moment and enjoying the rides instead of filming them???
Sadly some folks have yet to learn that sometimes you get more fun from simply enjoying something with nothing left when you stop except memories. I used to be in the capture the moment crowd to the nth degree... but after a trip to Disney where I later realized I didn't really have any real memories of some of the rides I realized that when I was so focused on capturing it with a camera I had managed to disrupt myself from actually enjoying the rides. I now go with a much lighter load, taking only a simple camera to catch an occasional meet and greet that the kids want, fighting the urge to photograph every ride, and enjoy the parks much more.
