Actually, VLC never specify the range 'end' for PLAY requests. We can if it's
needed (I will check if it fixes youtube rtsp).
But, I am not sure it will fix the issue for every servers anyway. For example,
it seems valid to me for a server to answer Range: 'begin'- when
requested Range: 'begin'-'end' with 'end' equal to the media length.
