Comment (by nadenislamarre):

 in the lowest network function, there is a test : "if
 (ff_check_interrupt(int_cb))" which make things not working
  i can : or remove this check, but i think that it could be usefull for
 something else, or
 add a parameter "force" to low network functions, but it touches the
 network.c of ffmpeg, so i guess you would not accept it easily
 the thing is that testing if the user requesting to quit in this function
 it not valid with the fact that rtsp protocol require network packet
 sending at the disconnection.

 Comment these 2 lines in libavformat/avio.c & libavformat/network.c fixes
 the problem :
         if (ff_check_interrupt(&h->interrupt_callback))
             return AVERROR_EXIT;
