This is too epic ;D

Now I wonder if monochrome videos combined with sound would be doable on a 15 MHz calc?

And if it's possible, would compression be too hard? I have a feeling that video+audio files will be very large...

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.



It work perfectly on wabbitemu, I didn't know a sound like this can be listen on 84+.

Compression is almost certainly impossible. I could actually almost see this being easy as a matter of fact. Just interlace the video and sound byte for byte and during the time that was previously used to decompress, write a byte to the screen.

Using this strategy, the video would be forced to run at 27 fps and the filesize would be 44KB/s (0.91DCS/s). Meaning 34 seconds of video. But it's possible.

Clearly no grayscale though. Sound requires uninterrupted CPU time and grayscale requires interrupts.

I see. It wouldn't be possible to make the video run at lower FPS?

Well, maybe. The video and audio have to be interlaced in some easy fraction. So assuming 23000 bytes per second on audio and 800 bytes per screen (768 + driver commands) 1/2 would be 14.5 fps. Which I guess is perfect. That was easy.

Well what I mean is couldn't the same video data be re-used every 2 frame? Or is that what you mean? 14.5 fps seems reasonable too because on-calc high FPS is blurry anyway.

Yes, that is exactly what I mean. So instead of video sound video sound video sound. It's video sound sound video sound sound.

Second. You were beaten by apcalc :D

But either way, the graphics are absolutely incredible! And is that the full song?
