Parts of a code I cannot Understand.It works though

here is my appMain.brs file

1 bitrates = [0]
2
3 'Swap the commented values below to play different video clips...
4 'srt = "file://pkg:/source/craigventer.srt" 'doNot Work
5 srt =""
6 ' Big Buck Bunny test stream from Wowza
7 'urls = ["http://ec2-174-129-153-104.compute-1.amazonaws.com:1935/vod/smil:BigBuckBunny.smil/playlist.m3u8"] 'No Work
8 'urls = ["http://184.xxx.xxx.xx9/vod/smil:BigBuckBunny.smil/playlist.m3u8"] 'This External works
9 urls = ["http://myserver:1935/vod/mp4:sample.mp4/playlist.m3u8"] 'My Server Works
10 qualities = ["SD"]
11 streamformat = "hls"
12 'streamformat = "mp4" 'this doesnot work
13 title = "Big Buck Bunny"

Here are the Questions

line 4 srt="file......" donot work and so I had to use srt="" (see line 5).I would like to fix this since it puts a caption on the bottom of the movie (see my debug log also) ?

line 7 the original url of the amazon bucket that comes with the examples do not work,I found the url in line 8 which works and enable me me to better debug my problem.Should the examples be updated for these url?

line 9,11 & 12 I found that I had to use "hls" as the stream format yet this is a vod(video on demand stream) of an mp4 file which is place in the content directory.What impact will this have on a live stream? is it that for all streams format from third party servers to the Roku DVP have to be "hls"?

Now for the stupid question of the day "what does the "smil" stands for in {urls = ["http://184.xxx.xxx.xx9/vod/smil:BigBuckBunny.smil/playlist.m3u8"]} and is it used for streaming live?"


Here is my debuglog

Re: Parts of a code I cannot Understand.It works though

1. Make sure you have the file, craigventer.srt, in the same source directory as your appmain.brs file.
2. Yes, the url, http://ec2-174-129-153-104.compute-1.am ... ylist.m3u8, no longer works and the examples should be updated with a correct url such as, http://en.wikipedia.org/wiki/Synchronized_Multimedia_Integration_Language

Re: Parts of a code I cannot Understand.It works though

Ok so Here is my Problem

I tried this
viewtopic.php?f=34&t=35019&start=0
viewtopic.php?f=34&t=41927&p=284442&hilit=video+player#p284442

And I read this
viewtopic.php?f=34&t=39143

and I know there are people who get the Videoplayer to work with hls but here is what i get when I tried the video player on a live stream

telnet 1st

created feed connection for http://xxx.xxx.xxx.xxx/live.xml
url: http://xxx.xxx.xxx.xxx/live.xml
Request Time: 16
Can't parse feed
list focused | current category = 0

then my xml is

xml file

<item sdImg="http://xxx.xxx.xxx.xxx/images/creat001.jpg" hdImg="http://xxx.xxx.xxx.xxx/images/creat001.jpg">
<title>NASA</title>
<contentId>10001</contentId>
<contentType>Talk</contentType>
<contentQuality>SD</contentQuality>
<streamFormat>hls</streamFormat>
<media>
<streamQuality>SD</streamQuality>
<streamBitrate>1500</streamBitrate>
<streamUrl>http://iphoned5.akamai.com.edgesuite.net/mhbarron/nasatv/nasatv_all.m3u8</streamUrl>
</media>
<runtime>1260</runtime>
</item>

when I validate the xml it has no errors
the feed works with both the simplevideoplayer and the customplayer
I have a wowza server and it works to with the simplevideoplayer and the customplayer even with my local live stream

I am using Roku 2 XD with developers version 2.9 and it side loads okay

I also change the StreamBirate to 0 and it still didnot work and my streamFormat is hls so can you tel me why its not parsing on the videoplayer?

and this URL also works http://www.nasa.gov/multimedia/nasatv/N ... c-IPS.m3u8 with the customplayer and simplevideoplayer

Re: Parts of a code I cannot Understand.It works though

Can't parse XML means there is an issue getting the data from your xml file. Although it passes the xml validator, you might try adding a declaration that it is an XML file at the top. The declaration is optional, but perhaps Roku needs it.

http://www.ibm.com/developerworks/xml/l ... index.html

An example declaration is
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Just a thought...I've never tried sending roku an xml file without it, and don't see issues by including it.

If that's not the problem, then look at your parsing code and see where the message "Can't parse feed" shows up. Then backtrack to determine the issue. Maybe your code is looking for a 'category' tag, and if that is missing it tosses up the message.

I notice that its say that I have unitialized variable (screen and category) but that was done in line 034 as a function so isn't it supposed to be available globally.

Should I change this to a sub instead of a function?
Should they be declared in the homescreen rather than the posterscreen?

I hope we get this I have been working on this none stop for the past three days.Passionate about it being solved

Re: Parts of a code I cannot Understand.It works though

This is ironic,the program runs on every leaf of the category except the live.xml and the syntax are all the same.I even put the hls in another category leaf and it breaks it too.

Re: Parts of a code I cannot Understand.It works though

Where it says "Can't parse feed"
replace that line of code with STOP
Then you can be right in the parse routine in the debugger and you can print xml to see what it shows you there, and run through the lines manually to figure out what the real issue is.

Re: Parts of a code I cannot Understand.It works though

The real section of code that is failing will look something like this:

Function load_show_feed(conn As Object) As Dynamic
If validateParam(conn, "roAssociativeArray", "load_show_feed")=FALSE Return invalid
Print "url: " + conn.UrlShowFeed
http=NewHttp(conn.UrlShowFeed)
m.Timer.Mark()
rsp=http.GetToStringWithRetry()
Print "Request Time: " + itostr(m.Timer.TotalMilliseconds())
feed=newShowFeed()
xml=CreateObject("roXMLElement")
If Not xml.Parse(rsp)
Print "Can't parse feed"
Return feed
End If
If xml.GetName() <> "feed"
Print "no feed tag found"
Return feed
End If
If islist(xml.GetBody()) = FALSE Then
Print "no feed body found"
Return feed
End If
m.Timer.Mark()
m.ParseShowFeed(xml, feed)
Print "Show Feed Parse Took : " + itostr(m.Timer.TotalMilliseconds())
Return feed
End Function

try replacing that line with stop
and in the debugger try to print rsp and see what shows up

First thing would be to print rsp to make sure it contains what you think it contains.
