I am having trouble implementing the resume feature from the springboard. I can read the registry and print the episode.id and saved position. When ShowVideoScreen(episode).Playstart = 30 is called from the console the ShowVideoScreen function ignores the index value and plays the video from the beginning. Any help is appreciated.

Springboard Function

Function ShowSpringboardScreen(episode)
    screen = CreateObject("roSpringboardScreen")
    screen.SetMessagePort(CreateObject("roMessagePort"))
    'screen.SetBreadcrumbText(leftBread, rightBread)
    screen.SetDescriptionStyle("movie")
    print RegRead(episode.id)
    screen.ClearButtons()
 
    if RegRead(episode.id) <> invalid and RegRead(episode.id).toint() >=10 then
       screen.AddButton(1, "Watch Now")    
       screen.AddButton(2, "Resume")    
    else
       screen.addbutton(1, "Watch Now")
    end if

    screen.SetContent(episode)
    screen.SetStaticRatingEnabled(false)
    screen.AllowUpdates(true)
    screen.Show()

    while true
        msg = wait(0, screen.GetMessagePort())
        
        if type(msg) = "roSpringboardScreenEvent"
            if msg.isScreenClosed()
                print "Screen closed"
                exit while                
            else if msg.isButtonPressed()
                print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
                if msg.GetIndex() = 1
                   PlayVideo(episode)
                endif
            else
                print "Unknown event: "; msg.GetType(); " msg: "; msg.GetMessage()
            endif
        else 
            print "wrong type.... type=";msg.GetType(); " msg: "; msg.GetMessage()
        endif
    end while

    return true
End Function

ShowVideoScreen Function in the modified VAST brs.

sub ShowVideoScreen(episode as object) as integer
    screen = CreateObject("roVideoScreen")
    port = CreateObject("roMessagePort")
    screen.SetMessagePort( port )

    metaData = {
            ContentType: episode.contentType,
            VideoId: episode.id,
            Title: episode.title,
            Description: episode.description,
            length: episode.length,
            Stream: {
                Url: episode.url
            }
            StreamFormat: episode.streamformat
        }

    screen.SetPositionNotificationPeriod(1)
    screen.SetContent(metaData)
    screen.show()
    
while true
        msg = wait(0, port)
        if type(msg) = "roVideoScreenEvent" then
            print "showVideoScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
            if msg.isScreenClosed()
                print "Screen closed"
                exit while
            else if msg.isfullresult()
                 RegDelete(episode.id)
            else if msg.isPartialResult()
                 'RegWrite(episode.id, nowpos.toStr())
            else if msg.isRequestFailed() then
                showVideoFailureMessage()
                'print "Video request failure: "; msg.GetIndex(); " " msg.GetData() 
            else if msg.isStatusMessage()
                print "Video status: "; msg.GetIndex(); " " msg.GetData() 
            else if msg.isButtonPressed()
                print "Button pressed: "; msg.GetIndex(); " " msg.GetData() 
            else if msg.isPlaybackPosition() then
                nowpos = msg.GetIndex()
                RegWrite(episode.id, nowpos.toStr())
            else if msg.isPaused() then
            else if msg.isResumed() then        
            end if
        else
            print "Unexpected message class: "; type(msg)
        end if
    end while

end sub

You'll either need to set the playstart value for the episode before sending it to the showvideoscreen routine, pass the value for playstart into the showvideoscreen routine to be set before playback, or re-read the value from the registry to re-obtain the resume position and set playstart for the episode before initiating playback. Any one of those should resolve the issue.

Thanks Destruk. I passed the Playstart value to the ShowVideoScreen function and it still ignores the playstart value. To note I am using the modified appvideoscreen from the VAST 2.0 SDK.

Springboard loop

    while true
        msg = wait(0, screen.GetMessagePort())
        
        if type(msg) = "roSpringboardScreenEvent"
            if msg.isScreenClosed()
                print "Screen closed"
                exit while                
            else if msg.isButtonPressed()
                print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
                if msg.GetIndex() = 1
                   PlayVideo(episode)
                endif
                if msg.GetIndex() = 2
                  PlayStart = RegRead(episode.id)
                  if PlayStart <> invalid then
                    episode.PlayStart = PlayStart.ToInt()
                    ShowVideoScreen(episode)
                  endif
                endif
            else
                print "Unknown event: "; msg.GetType(); " msg: "; msg.GetMessage()
            endif
        else 
            print "wrong type.... type=";msg.GetType(); " msg: "; msg.GetMessage()
        endif
    end while

From the Debugger console

[destruk]

Your playvideo routine isn't actually using the episode to play back the content - it is picking and choosing which variable sets to use and playing 'metadata'

metaData = {
ContentType: episode.contentType,
VideoId: episode.id,
Title: episode.title,
Description: episode.description,
length: episode.length,
Stream: {
Url: episode.url
}
StreamFormat: episode.streamformat
}

So you'd need to add playstart to that in this case.

destruk,

It seems to be working. Thanks again. To refresh the springboard screen to show the updated status of resume should I just call ShowSpringboardScreen(episode) again when the screen is closed?

Vast_VideoScreen.brs

while true
        msg = wait(0, port)
        if type(msg) = "roVideoScreenEvent" then
            print "showVideoScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
            if msg.isScreenClosed()
                  print "Screen closed"
                  ShowSpringboardScreen(episode)
                exit while

[destruk]

Yeah, show will update it with current data - so if you update your buttons and then call show, it'll be fine.
What I'd do is add it to the Springboardscreen routine

if msg.GetIndex() = 1
PlayVideo(episode)
endif
if msg.GetIndex() = 2
PlayStart = RegRead(episode.id)
if PlayStart <> invalid then
episode.PlayStart = PlayStart.ToInt()
ShowVideoScreen(episode)
endif
endif

After ShowVideoscreen(episode) and after PlayVideo(episode) I'd have it update the buttons there and refresh the screen before the end if.

Its all working. Thanks again.
