What do you mean, it "does not use additional resources"? A callback needs
to be called. That means the decoder has to frequently interrupt its work
and call some foreign function, consuming time and letting the caches get
cold in the process, precisely during the most speed-critical phase of a
video framework. And that just in the possible case someone would have the
same very specific needs as you.
And, by the way, can you please fix the time and date on your computer?
