Hello everybody,
I'm a real noob so I would realy apreciate if someone would tell me what's wrong with my code. First I just want to use Ascii code to convert an existing video (not using webcam) to text. So I copy past the script- changing it a litle bit after I had some error with font- Anyway, now I dont have an error message but the sketch is just a black screen ....
Here is the code :
import processing.video.*;
Movie video;
boolean cheatScreen;
String letterOrder =
" .`-_':,;^=+/\"|)\\<>)iv%xclrs{*}I?!][1taeo7zjLu" +
"nT#JCwfy325Fp6mqSghVd4EgXPGZbYkOA&8U$@KHDBWNMR0Q";
char[] letters;
float[] bright;
char[] chars;
PFont font;
float fontSize = 1.5;
void setup() {
size(1440, 1080);
video = new Movie(this, "Torrent.mts");
video.play();
int count = video.width * video.height;
font = loadFont("ProcessingSansPro-Regular-48.vlw");
letters = new char[256];
for (int i = 0; i < 256; i++) {
int index = int(map(i, 0, 256, 0, letterOrder.length()));
letters[i] = letterOrder.charAt(index);
}
chars = new char[count];
bright = new float[count];
for (int i = 0; i < count; i++) {
bright[i] = 128;
}
}
void MovieEvent(Movie m) {
m.read();
}
void draw() {
background(0);
pushMatrix();
float hgap = width / float(video.width);
float vgap = height / float(video.height);
scale(max(hgap, vgap) * fontSize);
textFont(font, fontSize);
int index = 0;
video.loadPixels();
for (int y = 1; y < video.height; y++) {
translate(0, 1.0 / fontSize);
pushMatrix();
for (int x = 0; x < video.width; x++) {
int pixelColor = video.pixels[index];
int r = (pixelColor >> 16) & 0xff;
int g = (pixelColor >> 8) & 0xff;
int b = pixelColor & 0xff;
int pixelBright = max(r, g, b);
float diff = pixelBright - bright[index];
bright[index] += diff * 0.1;
fill(pixelColor);
int num = int(bright[index]);
text(letters[num], 0, 0);
index++;
translate(1.0 / fontSize, 0);
}
popMatrix();
}
popMatrix();
if (cheatScreen) {
set(0, height - video.height, video);
}
}
void keyPressed() {
switch (key) {
case 'g': saveFrame(); break;
case 'c': cheatScreen = !cheatScreen; break;
case 'f': fontSize *= 1.1; break;
case 'F': fontSize *= 0.9; break;
}
}
Also, once I resolved this problem I would like to know how to use only a restreign number of letters (in a way that all the parts off the image that uses others letters will deseaper)
And sorry for my broken english, I'm french ;)
Thank you all for the help

Did you test that the file plays at all?
I never saw mts as an ending
Yes it plays! I tried it before Damn. An other guess?
Does the video play at all in Processing in a simple sketch?
If not, convert from mts to mov or mp4
As i said above, yes it plays en mts as a simple sketch. Of course I checked that first :)
@sevc -- good to know! I asked because you only said "it plays" after Chrisr asked if it plays "at all." Both the original question and your answer were ambiguous; that could have meant you were able to play it in Media Player or QuickTime.
