[vlc-devel] [PATCH] Fixed pause issue for streams without end (live cameras)

Actually the video being paused in a recorded video of a live camera. But
this stream does not return the end time.
Since there is no way of determining if a stream supports the PAUSE command
in RSTP 1.0, why check the end time? I don't think that removing the end
time check will cause anything to break.
