Need help about the "CustomPlaybackScreen" template

Hello,

I need someone's help please (and first of all sorry about my english. And note that I'm not a developper, just a regular guy trying to use Roku with its full capacity).
I found this template that does exactly what I want. It launches a video and displays a list of links while the video is still playing (if the user presses the OK button).
The only thing not working properly is when I add new entries to the video list, the new entries are outside the screen (since i add a dozen) and I can't see them when I scroll down (the list doesn't move in a way that the first link disappears so as the second becomes the first link visible in the list and a new one appears as the last one).
The code below makes the focus moves from a link to an another and when it reaches the last visible one it continues outside the screen.

The template uses these 2 files :


Sub RunUserInterface()
o = Setup()
o.setup()
o.paint()
o.eventloop()
End Sub

Sub Setup() As Object
this = {
port: CreateObject("roMessagePort")
progress: 0 'buffering progress
position: 0 'playback position (in seconds)
paused: false 'is the video currently paused?
feedData: invalid
playing: 0
playingPrev: 0
playlistSize: 10
canvas: CreateObject("roImageCanvas") 'user interface
player: CreateObject("roVideoPlayer")
load: LoadFeed
setup: SetupFullscreenCanvas
paint: PaintFullscreenCanvas
create_playlist_text: CreatePlaylistText
drawtext: false
eventloop: EventLoop
}

this.targetRect = this.canvas.GetCanvasRect()
this.textRect = {x: 520, y: 480, w: 300, h:200}

this.load()
'Setup image canvas:
this.canvas.SetMessagePort(this.port)

this.player.SetMessagePort(this.port)
this.player.SetLoop(true)
this.player.SetPositionNotificationPeriod(1)
this.player.SetDestinationRect(this.targetRect)

this.player.Play()
this.playingPrev = this.playing

return this
End Sub

This question has been resolved -- I have made a scrollable CustomPlaybackScreen template here: https://github.com/LeoWW/custom-playback-channel.

Interesting channel, but perhaps there would be more functionality if the videos played sequentially instead of stopping after each. Or have the list pop up after each video plays.

Then perhaps you should make it so Smiley Tongue

HHOS (only half-joking): one of the advantages of github is one can contribute. Fork the project, make the changes and if proud with the result, send pull request and LeoWW may merge it.

Right now I'm struggling to learn BrightScript so that's a bit above my competency level. But hopefully I will get to the point where I can share projects with others.

Hi,
Can you please share the template. I'll really appreciate it. The github isn't working anymore.
