Update URL parameters mid-stream?

I’m using a roVideoScreen to display live video stream as follows

        video = CreateObject("roVideoScreen")
        video.setMessagePort(msgPort)
        video.SetContent(videoclip)
        video.show()

where dump of videoclip looks like

streamformat: hls
streamurls: (list of 1)...
  List(0)= http://SVR/PATH/index.m3u8?param1=xxx&param2=yyy
streamqualities: (list of 1)...
  List(0)= SD
live: true
streambitrates: (list of 1)...
  List(0)= 0
playstart: -1

Where param1 is fixed but param2 is a ticket I obtain and has a limited life, so after few minutes the stream understandably dies.  I modified the code to obtain new ticket prior to the expiration time and tried to just update with

       videoclip=updateWithNewTicket()
       video.SetContent(videoclip)
       video.show()

and while the documentation states[/url:2c33qzvq]

You can call roVideoScreen.SetContent() while playing video
it doesn’t seem to work:

  • I don’t get an error on the new SetContent  (I presume calling video.show() again is not needed - its just the paranoia)

  • Tracking the HTTP requests in Wireshark (running tcpdump on my router, redirecting captured traffic to my desktop) I can see that the **.m3u8** requests are coming in with the new ticket but the **.ts** requests still have the original ticket - explaining the eventual failure.
    Wondering if anyone has seen this, if there is a cleaner way to do this
    I now see that there is more than one way to pass URLs into SetContent and that my method (StreamUrls) may be less than optimal for adaptive streams content metadata documentation[/url:2c33qzvq].  I’ll experiment with the “Stream” param instead of the “StreamUrls” but would appreciate any input/experience as that might take some serious refactoring

Thanks!

Just a quick follow up, hacking-in use of “Stream” instead of “StreamUrls” did not solve the overall problem and actually made it worse as now both “.m3u8” and “.ts” were both pooling original parameters

bump - anyone?
