This is a full music video playing in ComputerCraft.
Download:
http://www.mediafire...1eaczwnd4n/demoI've sped the Minecraft footage up 2.5 times and I've put the music behind it.
The demo will run at 20fps on a normal screen and at 10fps or more on a 0.5 scale 8x6 block Advanced Monitor (184x81 pixels).
The renderer is powered by the Surface API 1.5.3.
It's 30.7 MB, so I couldn't upload it to Pastebin.
To run this demo, you must first set the maximum drive space to at least 33 MB in the file %appdata%\.minecraft\config\ComputerCraft.cfg:
I:computerSpaceLimit=100000000
Then simple copy and paste the file into your ComputerCraft computer folder and run the file.

This is by far the coolest thing I've seen done in CC. I mean Bomb Bloke's GIF renderer was awesome, but this has music with it! You've turned a video you liked (judging by your YouTube channel) into a video that can be played with no lag inside CC. Awesome!

This doesn't have music with it, I put it on the YouTube video.
But thanks nevertheless!
It's really fun to test the boundaries of ComputerCraft.

That, plus the difference in frame-rate between the actual game and this video is also quite notable.
You could probably speed it up a bit by pre-calculating all your px/pys, and placing them in a table prior to doing the actual animation. No point in repeating the same mathematical operations for every single frame.
Still, this is very, very impressive! You've got it synced beautifully! That video's going in my archive. :)/>
By the way, what was your method of capturing the video data? Anything to do with
this?

I used a video to JPG converter and then I ran my own converter which I made in C#.
The color algorithms were copied from my RGB API.
Maybe I'll make a video player in the future.

So I thought to myself, "I wonder if that could be downloaded onto a CC computer without adjusting the config?", and tried converting the video to a GIF.
Still a meg and a half, but
here it is, if you're interested.

What command are you using to run it, what sort of computer are you running it on, and what version of ComputerCraft are you using?

It's cool to see that you can make GIFs from minute long videos.

I would like to thank you for making ComputerCraft.
I think it's the best mod ever made (and I've played a lot of them).
I have a lot of fun making programs and interacting with the community,
and that, of course, wouldn't be possible without you.

I worked on it for about 4 hours.
The first hour was spent on downloading the video and converting it to around 5000 JPGs.
The second hour was spent on writing my own converter which takes JPGs, downscales them,
converts them to ComputerCraft colors and then saves them to a file.
The last two hours were spent on writing, testing and optimizing the player.
I mostly tested it on a 8x6 block 0.5 scale monitor with 164x81 pixels, which really tests the limits of ComputerCraft and my scaling algorithms.
Loading the file in Notepad++ seems to work but it only responds every 10 seconds xD
When I run it, the PC shutsdown. Sublime text fails to load it.
This program is really demanding and maybe ComputerCraft can't handle it on your system.
It is also around 30.7 MB so it will most likely not load on Sublime text or Notepad++.

So theoretically you could do this with any music video, no matter how pixelated?

This is great! I love the conversion you've done. Though I see a few color gradient issues, it's near perfect. Seems like some of the areas between different colors are a bit overprocessed, and it kind of blurs the difference between the colors. But other than that, I'm amazed at this!
Sorry, I seem to point out the itty bitty things that aren't absolutely perfect, but most people wouldn't notice.

No need to apologize, I know too that it isn't perfect.
I used a video to jpg converter which compresses things a little so there are small artifacts around borders.
And the gradient issues are caused by the algorithm that converts RGB colors to CC colors , which basically checks for the lowest distance between CC colors in RGB and the RGB color in 3d space.

Ah, I thought that might be the case. Otherwise, it's rather impressive. I tried to get a copy of the song's midi file, so I can make it into a noteblock song, but nothing seems to work, due to the fact that the tempo won't fit within Minecraft's tick limit.

Yeah the tick limit is really limiting if you want to make music.
It would be awesome to have this song play in CC :D/>

Yeah, when I tried importing the music, I kept getting a tickrate of 7.5 t/s, which is just outside of the range that Minecraft can do, which is 5, 10, or if you use Note, 6.66

So it can either go 1.5x faster or 0.75x faster (or 8/9 times faster if you use Note), which isn't ideal :P/>

It may or may not help to know that the script is playing a video intended for rendering at 25 FPS (0.04s between frames), but due to the exact same limitation imposed on Note (that being the MineCraft server tick rate), it caps out at 20 FPS (0.05s between frames) - 4/5, or 80%, speed.
To complicate matters further, it always sleeps after rendering each frame, regardless as to the time already taken to render it. So if it takes more than a tick to get a frame drawn (which it almost certainly will when scaling over a full-sized external monitor), then that time + a 0.05 sleep = 40% speed (10 FPS). Ideally the script would keep tabs on the clock to work out whether it needs to use a timer or just instantly yield/resume before getting on with the next image…
There are 4967 frames, so at full FPS it plays for ~3:18, whereas in MineCraft it plays for at least ~4:08.

Yep, you're exactly right.
It took me around 8 minutes to record the video because it only ran at 10fps (8x6 block 0.5 scale monitor).
I didn't do any time calculations in the demo, so that's what's causing the problem.
I may make an update so that it includes timing calculations.

thinking about it, you could use a constant palette changer in craftos 2.0 when it comes out, giving you a better colour choice for each frame using the colours not used.

It's the screen drawings that is optimised.
Opening this in NP++ is pretty much the same thing as opening an actual video file.

That's possible now, but not when this was made :P/>
My
audio API is capable of playing NBS songs so if you made Move Your Feet in Note Block Studio you could totally play it alongside the video.
