Comment (by pszemus):

 I've figured it's because the image2 demuxer has AVFMT_NOFILE flag set.
 Because of that, the remote jpg file is requested again (the if clause is
 true in libavformat/img2dec.c:226).
 I would suspect that remote jpg files are requested only once. To
 accomplish this I'm thinking about removing the AVFMT_NOFILE flag from the
 image2 demuxer for my use case.
