Is there a reason why you're using SetContentList and not just SetContent?
For a video node, do you have an observer on the "state" of the video node? It should fire on any error.
SetContentList is the function mentioned in the documentation, although I have tried SetContent. In terms of observing the state of the Video player, I can observe that it is buffering, playing, paused, etc. my problem is that I can't detect if its getting a 404 when trying to buffer a non-existent video.
Thank you for help btw
I don't know why your "state" observer isn't working. I tried setting the URL to a nonexistent video on my server and my server returned a 404, my "state" observer fired, GetData() returned "error". and my video node "errorCode" was set to 404.
Edit: "errorCode" is set to -1. "errorStr" shows the 404.
Is that for a `roVideoPlayer` object or a `roSGNode` that represents a Video SceneGraph element? I have a "state" observer on the `roSGNode` for my video element, but it doesn't fire with errors, it just fires for states like "buffering", "paused", "playing", etc.
That's for a Video node. My "onState" observer function fires first with "buffering" and then with "error" when I set the URL to a nonexistent file. I've also used observers with message ports and waited on the port in the main thread. That looks something like this:
Function displayVideo(video as Object) as Integer
print "Displaying video: "; video["url"]
vn = m.video_node
vc = createObject("roSGNode", "ContentNode")
vc.url = video.url
vc.StreamFormat = video.StreamFormat
print vn.observeField("position", m.port)
print vn.observeField("control", m.port)
print vn.observeField("state", m.port)
vn.content = vc
vn.setFocus(true)
vn.control = "play"
while true
msg = wait(0,m.port)
msgtype = type(msg)
print msgtype
if msgtype = "roSGNodeEvent" then
node = msg.GetNode()
field = msg.GetField()
data = msg.GetData()
print node, field, data
if field = "position" then
position = data
else if field = "control" and data = "stop" then
exit while
else if field = "state" then
if data = "finished" then
exit while
else if data = "buffering" then
m.video_screen.visible = true
else if data = "error" then
print vn.errorCode
print vn.errorMsg
print vn.errorStr
print vn.errorInfo
else if data = "playing" then
'
else if data = "paused" then
'
end if
end if
else if msgtype = "roSGScreenEvent" then
print msgtype, msg.GetData(), msg.isScreenClosed()
vn.control = "stop"
exit while
end if
end while
vn.control = "stop"
print vn.unobserveField("position")
print vn.unobserveField("control")
print vn.unobserveField("state")
return position
End Function
and produces this output:
roSGNodeEvent
video control play
roSGNodeEvent
video state buffering
roSGNodeEvent
video state error
errorCode: -1
