How to switch (or stop) hls stream based on time event

Hi,

I got the sample player script to successfully play an m3u8 we stream throughout the day. However, I want to switch that stream at a particular time to a second stream.

I have my time method working fine (if the app on the private channel begins within either the 1500 or 1600 hour, stream 2 plays, otherwise stream 1 plays.

And in my event loop, I am checking the time. My debug console shows that the time code fires; however, I do not know how to reinitialize the video player:

Tried this:


        date = CreateObject("roDateTime")
        showtime = date.getHours()'date.getSeconds()
        print "|-o-| ts " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
        if showtime = 19 Or showtime = 20 then
        'if showtime > 19 And showtime < 30 then
            print "It's Showtime!!! " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
            if videoclip.StreamUrls = "http://path/to/stream_6@156963/master.m3u" then 
                player.Stop()
                video.Close()
                videoclip.StreamUrls = "http://path/to/stream_7@156963/master.m3u"
                video.SetContent(videoclip)
                video.show()
            endif


The roku lives in the office (no tv at home :D), so tomorrow, I will attempt to call the initial method:


        date = CreateObject("roDateTime")
        showtime = date.getHours()'date.getSeconds()
        print "|-o-| ts " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
        if showtime = 19 Or showtime = 20 then
        'if showtime > 19 And showtime < 30 then
            print "It's Showtime!!! " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
            if videoclip.StreamUrls = "http://path/to/stream_6@156963/master.m3u" then 
                player.Stop()
                video.Close()
                showSpringboardScreen(item)
            endif


But if somebody has a better idea, I'll try that, too.

Thanks,

    I believe I figured this one out:

    In the showSpringboardScreen function:

                            date = CreateObject("roDateTime")
                            showtime = date.getMinutes()'date.getSeconds()'date.getHours()'screen.GetMessagePort()
                            if showtime = 0 or  showtime = 10 or showtime = 20 or showtime = 30 or showtime = 40 or showtime = 50 then
                                fcstream = "http://uri/i/adultswim_7@156963/master.m3u8"
                            else
                                fcstream = "http://uri/i/adultswim_6@156963/master.m3u8"
                            endif 
                            DisplayVideo(fcstream)


    displayVideo accepts fcstream as String

    Then in the roVideoScreenEvent loop, I check the time (looking at minutes instead of hours to test the functionality)

            date = CreateObject("roDateTime")
            showtime = date.getMinutes()'date.getSeconds()'date.getHours()'screen.GetMessagePort()
            print "|-oo-| ts " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
            if showtime = 0 or showtime = 10 or showtime = 20 or showtime = 30 or showtime = 40 or showtime = 50 then
                if videoclip.StreamUrls = "http://uri/i/adultswim_6@156963/master.m3u8" then 
                    print "{-o-} player.Stop()"
                    player.Stop()
                    print "{-oo-} video.Close()"
                    video.Close()
                     print "@@ It's Showtime!! " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
                    displayVideo("http://uri/i/adultswim_7@156963/master.m3u8")
                endif
            else if showtime = 5 or showtime = 15 or showtime = 25 or showtime = 35 or showtime = 45 or showtime = 55 then
                if videoclip.StreamUrls = "http://uri/i/adultswim_7@156963/master.m3u8" then 
                    print "{-o-} player.Stop()"
                    player.Stop()
                    print "{-oo-} video.Close()"
                    video.Close()
                     print "@@@It's RerunTime!! " + videoclip.StreamUrls + " :: " + Str(date.getHours()) + " : " + Str(date.getMinutes()) + " : " + Str(date.getSeconds())
                    displayVideo("http://uri/i/adultswim_6@156963/master.m3u8")
                endif
            endif


    Now that I have the functionality working, I'll look for more elegant / efficient solution.

    Thanks,
