Movie Player

[DaveMcW]

I built a full color movie player. See it in action:



Or download the save: sandstorm.zip


It has a 178x100 display, and 34MB of memory. In theory it could run at 60 FPS, in practice it runs at 1 FPS in Factorio 0.14.

I designed the movie player in 10 sections, then built them all from the same blueprint.

Each section has 3 parts: display, decoder, and memory.

Display

I use this combinator design to fit many color signals on one wire.

The processing time is O(n^2) where n is the number of signals the wire. So I split the signals between 5 wires to improve performance. Three wires can run along a column of combinators, and the other two hop along lamps to reach the distant combinators. The wire diagram looks like this. (They are really all green wires.)

Decoder

The decoder takes 5x 30-bit signals as input, and produces 50x 3-bit colors as output.

Here is how it works on a binary level:

Encoder

I published my encoder script on GitHub: https://github.com/DaveMcW/factorio-movie-maker

Memory

The memory uses a simple lookup scheme, with a frame select signal on the green wire and 180 data signals on the red wire.

This decider combinator setup has poor performance when used with a high number of signals. Here are my performance stats:

This is all well and good, but... Songname?

[Smarty]

holy.. but... but..

That is amazing!

[Acarin]

Dave, you never cease to amaze me with your Factorio skills. That is... Extremely impressive

[Grimakar]

You really should put this save to the Performance optimization - post your saves Thread. This really makes my computer burn

[Necriptos]

holy hell how on earth

[jasa_m]

amazing!!

[steinio]

How can i watch the Netflix Series?

[RichPL]

I'm out....

srs tho.

I consider myself not too un-smart, heck sometimes I get a little swell of pride when I do something moderately clever. But this, this blows my freekin' mind.

Amazing! Congratulations!

Factorio might get an AO rating now.

really impressive. holy cow.

But before we talk about the circuit network, we have to talk about parallel universes.

Hey Dave, you made it. The Gamestar is writing about you^^

yeas got news coverage lol

Holy crap, 34 megabytes of memory! With that you could store the entirety of Doom 1 and 2 and still have 8MB to spare. That's seriously impressive!
