Does the MovieMaker class exist in 2.0b9, or not?

in Core Library Questions • 4 months ago

I downloaded an example sketch ( Optical Flow by Hidetoshi Shimodaira) that uses the MovieMaker class to save screen output to a .mov file. The sketch runs just fine in 2.0b9 on my MacBook Pro, and saving movies works fine too.

But when I try doing the same thing in my own sketch, I get an error:

Cannot find a class or type named "MovieMaker"

Hunting around in the forums, I found this thread, among others, suggesting that the MovieMaker class was removed in Processing 2.0 and should no longer be used. Now I'm totally confused. If MovieMaker was removed, why does the Optical Flow sketch work?

Failing that, can anyone suggest a better way to render out movies in realtime? (I've tried the officially recommended method of saving out individual frames one at a time, but doing that slows my app down from 24fps to about 12fps because of all the disk access, so it's useless to me.)

Yes, this class has been removed from Processing 2. I don't know how the sketch can work on your copy, it is indeed puzzling, unless you have some library replacing this one?
Is this sketch fluid while saving the movie? Because in general, you have to choose between real-time sketch and recording sketch, they are rarely possible simultaneously... Saving movie frames or individual frames should use the disk I/O in similar ways, anyway (unless doing lot of operations in memory, Ram disk is an option if you have plenty of it).

Yeah, the performance is definitely sluggish, even when using the MakeMovie object. Not very different from when I save individual frames, really. So I guess it's kind of a moot point.

It's good to know that I'm not the only one who has trouble recording frames in realtime! I suppose I can just go old school, put a camera on a tripod and point it at my screen. :-)

Thanks!

A good screen capture utility, like Fraps (payware, but one of the bests) can offer real time capture while not hogging the CPU. There are some free softwares as well, that you can try: they might be less efficient, but can be enough for your needs.
