Roku Developer Program

I have tried several different ways to get my captions to appear on my channel. I looked at the current method for enabling captions found in the blog post here: http://blog.roku.com/developer/2014/01/16/new-closed-caption-features-for-brightscript-developers/, and so I tried and this is what I came up with. I am using the Video Player example and so on my appVideoScreen I have this:

Function showVideoScreen(episode As Object)

    if type(episode) <> "roAssociativeArray" then
        print "invalid data passed to showVideoScreen"
        return -1
    endif

    port = CreateObject("roMessagePort")
    screen = CreateObject("roVideoScreen")
    screen.SetMessagePort(port)

    screen.SetPositionNotificationPeriod(30)
    screen.SetContent(episode)
    screen.Show()
	
    'Uncomment his line to dump the contents of the episode to be played
    'PrintAA(episode)

    while true
        msg = wait(0, port)

        if type(msg) = "roVideoScreenEvent" then
            print "showHomeScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
            if msg.isfullresult()
            	print "Video Completed Playback Normally"
            	RegDelete(episode.ContentId)
            	print "deleted bookmark for playback position"
            else if msg.isScreenClosed()
                print "Screen closed"
                exit while
            elseif msg.isRequestFailed()
                print "Video request failure: "; msg.GetIndex(); " " msg.GetData() 
            elseif msg.isStatusMessage()
                print "Video status: "; msg.GetIndex(); " " msg.GetData() 
            elseif msg.isButtonPressed()
                print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
            elseif msg.isPlaybackPosition() then
                nowpos = msg.GetIndex()
                RegWrite(episode.ContentId, nowpos.toStr())
            else
                print "Unexpected event type: "; msg.GetType()
            end if
        else
            print "Unexpected message class: "; type(msg)
        end if
    end while

End Function

Function EnableCaptions(player as object) as void
            di = CreateObject("roDeviceInfo")
            captionsMode = di.GetCaptionsMode()

            if (captionsMode = "On")
                player.ShowSubtitle(true)
                player.ShowSubtitleOnReplay(false)
            else if (captionsMode = "Off")
                player.ShowSubtitle(false)
                player.ShowSubtitleOnReplay(false)
            else if (captionsMode = "Instant Replay")
                player.ShowSubtitle(false)
                player.ShowSubtitleOnReplay(true)
            endif
    End Function

and then I put the caption URL into my XML Document like this:

, and my Global Captions are enabled, and when I try to show caption tracks on my channel, it tells me there are no caption tracks available. Can someone please tell me what I am doing wrong?

Thanks!!

Are you calling EnableCaptions?

[srbsdean]

I believe I am. I started a new function on the appVideoScreen.brs doc called: "Function EnableCaptions(player as object) as void"

Is that what you mean?

You've defined the function, but you actually have to call it for it to do anything.

Thank you for your assistance, I guess I am out of my league. I don't know how to do those types of things, if I can't find it them in an example. Do you have a sample or a script that you could show me?
