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:
Code: movie.draw(x,y,160,120); |

ow ! That was easy ! So easy that I owe you some apologize for the disturbing
 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(); Code: 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 ! :p |

this:
Code: unsigned char r = pixels[i * 3]; unsigned char g = pixels[i * 3]; unsigned char b = pixels[i * 3]; should be: Code: unsigned char r = pixels[i * 3]; unsigned char g = pixels[i * 3+1]; unsigned char b = pixels[i * 3+2]; |
