HLS Problem

the screen is fully loaded with the bar but the video never starts.
the debug window shows that if the segments are obtained, and is constantly updated.
on VLC the url worked.

   port = CreateObject("roMessagePort")
    video = CreateObject("roVideoScreen")
    video.SetMaxVideoDecodeResolution(1280, 720)
    video.setMessagePort(port)
    bitrates  = [0]
    urls = [dStream]
    qualities = ["SD"]
    StreamFormat = "HLS"
    title = dTitle
 
    videoclip = CreateObject("roAssociativeArray")
        videoclip.StreamBitrates = bitrates
        videoclip.StreamUrls = urls
        videoclip.StreamQualities = qualities
        videoclip.StreamFormat = StreamFormat
    	videoclip.Title = title
  	videoclip.SwitchingStrategy="full-adaptation" 
      
    video.SetContent(videoclip)
    video.show()

on ssh
