But would that change do anything? The output from yuvdenoise says:
INFO: [yuvdenoise] Frame border : x: 2 y: 2 w:65534 h:65534
w/h look like (w)idth/(h)eight. Say for example, the incoming image size
was 640x480, then with -b 2,2,-2,-2, shouldn't the output be:
INFO: [yuvdenoise] Frame border : x: 2 y: 2 w:636 h:476
I.e., shouldn't the code look something like this (where b(x), b(y), b(w)
b(h) are the values given to the -b flag):
x=b(x); y=b(y)
if ( b(w) < 0 ) {
w=incoming_header_width - b(x) + b(w);
} else {
w=b(w);
}
if ( b(h) < 0 ) {
h=incoming_header_height - b(y)+ b(h);
} else {
h=b(h);
}
