RoUrlEvent not retrieving videos from server?

Archived

Hello! I am trying to retrieve videos from a server to play on my Roku channel. I’ve called every function on the urlEvent to see what the issue is. I’m not getting any errors on the telnet, so I’m not sure why the videos aren’t coming through. There are other files I have that connect to the server, but this is the main one that should be getting the videos. Here is the snippet of code:

function queryVideo( id, parameters = Invalid )

  path = "/videos/" + id 
  path = path + "?" + uriEscape( "include[source]" ) + "=" + uriEscape( "true" ) 
  request = createRequest( path )
 
  if parameters <> Invalid    
    request = request.where( parameters )
  end if

  if request.query()

    print "queryVideo: waiting for message"
    while true
      
      message = wait( 0, request.getMessagePort() )
      
      if type( message ) = "roUrlEvent" then 
        event = message.getInt()
        print "Event message: "; event
        videoContent = message.getString()
        failure = message.getFailureReason()
        if videoContent = "" then
          print "Failure reason: "; failure
        else
          print "Video content not empty"
        end if 
      print "Failure reason: "; failure
      print "Video content: "; videoContent
      responseCode = message.getResponseCode()
        print "Get response code: "; responseCode
        ' stop
        response = createResponse( message )
        if response.isSuccess() then
        print "Response is successful"
          resource = response.getResources()[0]
          if resource <> Invalid then
            resource[ "sources" ] = response.getResourcesByName( "video_sources" )
            return resource
          else 
            return Invalid
            print "Invalid"
          end if
        else 
          print "queryVideo failed"
          return Invalid
        end if
      end if

    end while

  end if

  return Invalid

end function

Everything is sent to the proper URL, and the telnet notifies me that a resource has been returned. Here is what I get:

queryArtifactArtifacts: waiting for message
queryArtifactArtifacts: returned 1 resources.
queryVideo: waiting for message
Event message:  1
Video content not empty
Failure reason: OK
Video content: {"$this":{"name":"videos","type_name":"video","ids":[124189]},"videos":[{"type_name":"video","id":124189,"created_at":"2015-06-04T19:39:02.929295Z","updated_at":"2015-06-09T00:36:45.615637Z","content_type":"video/mp4","filename":"NA_MTO_DGR_206-BXX.mp4","size":null,"storage_key":"cnU1ZinATsG6zWFx4HcS_NA_MTO_DGR_206-BXX.mp4","height":null,"width":null,"duration":"580","picture_id":"125465","codec":null,"codec_long":null,"color_and_chroma":null,"profile":null,"level":null,"bit_rate":null,"frame_rate":null,"display_aspect_ratio":null,"sample_aspect_ratio":null,"audio_codec":null,"audio_codec_long":null,"audio_channels":null,"audio_bit_rate":null,"audio_sample_rate":null,"audio_channel_layout":null}]}

Sorry, I don’t understand what the problem is. You are making a request for a URL and correctly retrieving it. All the code you’ve posted seems to be working fine. But what does “videos aren’t coming through” mean? Do you have a VideoPlayer somewhere else in your code that’s not working?

I meant that the videos from the server do not play when I click them. The screen just says “Retrieving” and never ends up playing the video chosen. My videoScreen file seems to be working perfectly fine as well since it does not give back any error messages in telnet. Everything seems to be connected from what I can see.

Ok, but you didn’t post any code or messages from your VideoScreen, you posted a function that downloads a text file and the messages that result from a successful download. This has nothing to do with playing video.

Do you see any messages on the debug console when you click a video?

Whoops, I just assumed the issue was with the code I posted, since, no, I do not get any error messages on the videoScreen when I click a video. Here is the videoScreen code:

function createArtifactVideo( artifact, relatedArtifacts )

  ArtifactVideo = {

    initialize:         initializeArtifactVideo
    populate:           populateArtifactVideo
    show:               showArtifactVideo

    screen:             Invalid
    port:               Invalid

    artifact:           Invalid
    relatedArtifacts:   Invalid
    artifactVideo:      Invalid

    index:              Invalid
    lastIndex:          Invalid

  }

  ArtifactVideo.initialize( artifact, relatedArtifacts )

  return ArtifactVideo

end function

function initializeArtifactVideo( artifact, relatedArtifacts )
 
   m.screen = createObject( "roVideoScreen" )
   m.port = createObject( "roMessagePort" )
   m.screen.setMessagePort( m.port )

   m.relatedArtifacts = relatedArtifacts
   m.populate( artifact )

end function

function showArtifactVideo()
   
  m.screen.show()

  while true  

    message = wait( 0, m.port )
    if type( message ) = "roVideoScreenEvent" then
    print "Video Screen message: "; message.getMessage() " and Index: "; message.GetIndex()
      if message.isScreenClosed()
        print "Screen closed"
        exit while
        lastIndex = m.relatedArtifacts.count() - 1
        for index = 0 to lastIndex
          if m.relatedArtifacts[ index ].id = m.artifact.id then
        exit for
          end if
        end for
        if ( index + 1 <= lastIndex ) then
          m.initialize( m.relatedArtifacts[ index + 1 ], m.relatedArtifacts )
          m.show()
        end if
      end if   
    end if  
    
  end while

end function

function populateArtifactVideo( artifact )

  if artifact <> Invalid then

    m.artifact = artifact
    m.artifactVideo = queryVideo( artifact.provider_uid )

    ' stop

    content = artifactToContent( artifact )
    content[ "streamUrls" ] = ""
    
  ' content = {
  '   streamUrls: "http://videos.boxxspring.com/" + video_sources.storage_key 
  '   streamBitrates: [ 0 ]
  '   streamQualities: [ "HD" ]
  '   streamFormat: "mp4"
  ' }

  ' if content.streamUrls <> invalid then
  '   print "video URL is valid"
  ' else
  '   print "video URL is INVALID"
  ' end if

  m.screen.setContent( content )
 
  end if
 
 end function

The telnet shows ithe sending/retrieving of the URL – nothing is broken. So confused! :neutral_face:
Thanks!
