Why dows FFmpeg need to perform 3 HTTP GET requests for every JPG image:
http://i.wp.pl/a/f/film/033/47/13/0251347.jpg
http://i2.cdn.turner.com/cnnnext/dam/assets/150914044245-swim-

https://www.yahoo.com/sy/nn/fp/rsz/091415/images/smush/kimdavis-

I know that those are Byte-range requests but the file descriptor (nor
connection) isn't reused.
