Resize a video

beginners
#1

Hello,

I wondered if there is a “resize” function for a video. I started my work based on MoviePlayerExample and can’t find out how to resize the sample video with the hand at e.g(160x120)

any ideas ?
Thanks a lot.

if it’s just for drawing it, it’s so easy as:

  
movie.draw(x,y,160,120);

ow ! That was easy ! So easy that I owe you some apologize for the disturbing :wink:
Thanks for the answer.

I know stumble on a new problem. I am using “ofVideoPlayer:pixels” to get the value of all the pixels of a the upper horizontal row of my video. I want to use those values to define the color of each line I am tracing between the video and the top of my window. I just got blue or black and white. What’s wrong in my code. How to get the color informations ?

unsigned char * pixels = vidPlayer.getPixels();

  
for (int i = 0; i < vidWidth; i+=1)  
{  
        unsigned char r = pixels[i * 3];  
        unsigned char g = pixels[i * 3];  
        unsigned char b = pixels[i * 3];  
        ofSetColor(r, g, b);  
        ofLine( (vidPositionX - vidWidth / 2 ) + i, 0, (vidPositionX - vidWidth / 2) + i, vidPositionY - vidHeight / 2);  
 }

Thanks in advance.
NB : I am amazed by the quickness of openFrameWorks ! :stuck_out_tongue:

this:

  
        unsigned char r = pixels[i * 3];  
        unsigned char g = pixels[i * 3];  
        unsigned char b = pixels[i * 3];

should be:

  
  
        unsigned char r = pixels[i * 3];  
        unsigned char g = pixels[i * 3+1];  
        unsigned char b = pixels[i * 3+2];

Thank you very much. Exactly what I was looking for :wink:

Try use the program VidCrop PRO, to me has very much helped.
