Roku Developer Program

How does one use the roTuner API with ifVideoPlayer? I've tried to copy the way Content-Metadata is configured in the Scene Graph (SimpleTuner) example but I get a "failed to create media player" error every time. Are there any constraints when using Broadcast video vs streaming? I might have triggered this error by also using SetDestinationRect.

Any help would be greatly appreciated.

Looking into it...

Joel, the "GetNowNextPrograms" method on roProgramGuide also doesn't exist. I get a BrightScript error. I'm the latest TCL TV firmware (7.1).

Figured out the issue. I can literally just pass the content_metadata value from channel info to ifvideoplayer. Trying to create an AA that looks like the example doesn't work.

Have you got an example of what you did? I was playing about with the roTuner stuff last week and could only get the Screne Graph stuff to work, and I've yet to dive down that path.
I want to guess that you've done something like this, but I'm away from the kit to test

  tuner = CreateObject("roTuner")
  if (tuner <> invalid)
    channels = tuner.GetChannelList()
    channelInfo = tuner.GetChannelInfo(channels[0])
    if channelInfo <> invalid
      port = CreateObject("roMessagePort")
      canvas = CreateObject("roImageCanvas")
      canvas.SetMessagePort(port)
      canvas.SetLayer(0, { color: "#00000000", CompositionMode: "Source" })
      canvas.Show()

      player = CreateObject("roVideoPlayer")
      player.SetMessagePort(port)
      player.SetDestinationRect(canvas.GetCanvasRect())
      player.SetContentList(channelInfo.content_metadata)
      player.Play()
      while true
        msg = Wait(0, port)
        if msg.isRemoteKeyPressed()
          index = msg.GetIndex()
          if index = 0 ' <BACK>
            print "Closing video screen"
            player.Stop()
            exit while
          end if
        end if
      end while
    end if
  end if

Your mistake is with this line (I think):

player.SetContentList(channelInfo.content_metadata)

It should be:

player.SetContentList([channelInfo.content_metadata])

To make it into an array.

Thanks retrotom, remote testing appears to work, although I'm not actually in front of the TV to check.
Also wondering if GetNowNextPrograms is actually supported, or a typo is involved in the OS/docs.

I'm hoping it's just a typo. I've had to settle for just calling GetPrograms on each channel from the list. While it mostly works for my needs, I'm not confident this is the best route.

Yes :). FWIW:

BrightScript Debugger> pg = createObject("roProgramGuide") : now = createObject("roDateTime")
BrightScript Debugger> ? pg.getNowNextPrograms("2.4", now)
<Component: roArray> =
[
    <Component: roAssociativeArray>
    <Component: roAssociativeArray>
]

Speaking of which... WTH is roContentMetadata ?!

BrightScript Debugger> ? pg.getNowNextPrograms("2.4", now)[0]
<Component: roAssociativeArray> =
{
    category: 
    content_metadata: <Component: roContentMetadata>
    description: 
    duration: <Component: roDateTime>
    format: <Component: roAssociativeArray>
    id:  330
    name: BUZZR Time Machine
    start_time: <Component: roDateTime>
}
