That is just... intense. I didn't know you could swap pages that quickly, though.
Swapping pages is instant. Meaning it's the fastest way to move data. (You're not really moving it though.)

It doesn't seem to work on a real calc, what do you have to do with the files?
It should work. I was showing people at school. Send both files, from the same post, and run the program. The app only contains data. Oh, and it definitely won't work on an 83+ for so many reasons.

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

Pity :( Even small videos wouldn't even fit, anyway. But this is epic nonetheless. Great job!

Would it be possible to run this using msd8x?  The videos can be made to run longer then...

And with a TI-83+SE?

Compression artifacts? I don't think so!

I even made a few more fixes so this one is running at 15 fps meaning that this 30 sec file is 500k. Compression's not done yet though.

Yes. An 83+SE is essentially just an 84+SE without a USB port. They even have the crystal timers, which the Nspire lacks, meaning this won't work on that either.

Oh, and so I don't create any suspense. What I did was just have super not change the image sizes, so that way they were pixilated in 480p when I sent them into GIMP which gets rid of those artifacts when it cuts the size.

Ah!  I guess that explains why I didn't have any artifacts when I did the train video (resized with GIMP), but I did with the Rickroll (resized in SUPER).

Also, I should note, this is extremely amazing to see videos on the 84+.  With such a "slow" processor compared to the Nspire, I am amazed that you get that good speed!

"Look at your calculator. Now at me. Now back to yours. Now back to me. Sadly, I'm not in your calculator, but you can make it look like it by using thepenguin77's 4-level grayscale program for ti-8x series calculators."

...also +1. Props to you on this!

It just happened. The first ever true calculator Rick Roll.



Description:
Quote
Using my new program for the 84+, FourVid, I am able to play 4 level grayscale videos on the calculator. Then by combining that with my other program, TruSound, I am able to play videos sync'd with sound!

Obviously this is on an 84+SE. Both the sound and video files are 1.3MB in size, which means that I had to clear the memory on both of them before I started.

Here are the files needed to play it. Just note that the sound file is clocked for wabbitEmu (15MHz) so it will run too fast on a real calculator (16MHz).

Also, if you have sent any of my videos to your real calc. You may have noticed that you are missing some memory. This is because some of the app pages started with $FF and the calculator won't delete them. So the only way to get the memory back is to back up everything on your computer and then clear All Mem. This RickRoll video also suffers from the same problem. Sorry about that. I'll fix that soon.

Haha, the files are too big for this post. Video, player, song.
