The width and height are set to be the same as the source.  I didn't set any linesize in my code.  I have the following code

                int numBytes = avpicture_get_size(imgPixFormat, vp->width, vp->height);
                vp->bmp = new uint8_t[numBytes*sizeof(uint8_t)];
                avpicture_fill((AVPicture *)vp->frame, vp->bmp, imgPixFormat, vp->width, vp->height);

     vp>frame is AVFrame*
     vp->bmp is uint8__t*
     width and height are int;

Or do I need to set my linesize?
