sorry,this is the code snippet
AVFrame *targetFrame=.....
int height=imageHeight();
int width=imageWidth();
for(y=0;y<encoder.getVideoParams().height ;y++){
for(x=0;x< encoder.getVideoParams().width;x++){
targetFrame->data[0][index][(y* width)+x]=(x%255); //R
targetFrame->data[0][index][(y* width)+x+1]=0; //G
targetFrame->data[0][index][(y* width)+x+2]=0; //B
}
}
