playback not displaying anything on the screen

Hi, I'm testing the recording and playback with a screen sharing application.

I set up a WebDAV server and verified that session recordings are successfully stored.

When trying playback, however, I can't see anything on the screen.

Debugging output suggests that archiveManager.totalTime is non-zero,

connection is successfully established, and playback indeed was happening at the background.

I am testing with the sample playbackGuest application.

Any idea why this might be happening?

Eric,

Great to hear it works.  By the way, we will fix up the SDK to return a better error in the near future.

Thanks Alex

Great! That's working correctly now.  I just had to double check my archiveID.

Thanks a lot,

Last time I got a "no-fms" error it meant the same thing as "invalid instance" (I misspelled my room + archiveID). I saw an good auth message and right after taht "no-fms", then we found that I was passing in the wrong archive ID. Voila problem solved

Hope that helps

Hi:

Any update on my no-fms?  I seem to be connecting just fine when recording to the repository.  Playing back streams is where I'm coming short.

Thanks again,

One quick observation:

I learned that one potential cause of the problem is that

I added <AudioPublisher> and <AudioSubscriber> to my ConnectSessionContainer.

The thing is, I enable voice chat only when a user chooses to enable it.

For streams that do not have audio data, the whole application doesn't show on the screen.

Hi Nikola,

Thanks for your prompt reply.

Good news is, now I see the playback control! Trying with a new room + some other things I tried seem to have made it work!

I have no idea why the playback application trace doesn't indicate its starting. I apparently ran the same application targeted at the same room/archiveID over and over for my debugging. But shouldn't it still "start" every time I test?

Calling registerRepository multiple times was by design. I'm planning to get rid of that line soon

Best,

Juho

Hi Juho,

I peeked into your logs and I do not understand few things that are happening there. 

First, I cannot find your playback's "application started" traces which is really strange, as if application started days ago.  I am still grepping for it in archived logs.  My suggestion would be to start fresh with a new room or a different archiveID and see if that untangles you from the current issues and you get to a working version.

Second, I see lots of registerRepository calls in the logs.  Is this intentional?  You only have to register a repository once for the whole account.

Hope this helps,

Nikola

Yeah... then no more debug output is shown. Do you have any pointers to what I can try?

Is that all you see in terms of logs?  If that is true, it appears that your recordings is not even initializing its playback streams.

Thanks,

To get the debug output, I'm not using LCCS classes.

I'm using a Firefox extension FlashFirebug 3.0.2 w/ Firebug 1.8.1 under Firefox 5.0.1.

Hi, to make things simpler, I tested the provided Recording and PlaybackGuest app in the SDK.

Recording seems to work fine and a zip file is saved in the WebDAV server.

I still don't see anything when I run the PlaybackGuest app. Here's what I get from the console. (most recent at the top)

Small update:  I was able to open the archive on my repository server and view the streams.  They look legitimate.  However, the playback application does not play the stream specified.

Ok, I have tried the recording and playback from the sample applications and I get the recording to show in my repository fine, but it will not play back.  The error I get is "no-fms":

Alex: The above code was an example of my playback application.  I don't think I need an audio publisher for that purpose.

1) Does the simple app "Recording" that comes with LCCS SDK work for you for *video* recording ( audio isn't recorded in it ) ?

2) I noticed you don't have an audio publisher just a subscriber, here's what I use to get audio to record:

I'm having a similar issue in playback.  I have updated my video conference recording applications to use the new sdk and now when I make a new recording I don't see video or hear audio.  I do still see the progress bar moving.

My code is a playback with a slider, it logs in (cSession.login()) after the flashvars are read in on application_complete.  This sets my roomUrl and archiveId to the appropriate values to enter a room.  Visible is changed to true (the Session Container does display currently, just not video or audio) when creationComplete fires on Session Container:

<s:HGroup width="100%" height="100%" horizontalAlign="center" verticalAlign="middle">
               <rtc:ConnectSessionContainer id="cSession" authenticator="{auth}" width="100%" height="100%"
                                                   roomURL="{roomURL}"  autoLogin="false"
                                                   archiveID="{archiveId}" creationComplete="sessionComplete()" visible="false">
                    <mx:HBox top="10" right="10" left="10" bottom="10" horizontalAlign="center" verticalAlign="middle">
                         <mx:VBox width="100%" height="100%" horizontalAlign="center" verticalAlign="middle">
                              <rtc:WebCamera width="90%" height="80%" />
                              <rtc:AudioSubscriber id="aSubscribe" />
                              <mx:HBox width="90%">
                                   <s:Button id="playButton" verticalCenter="1" width="32" height="32" click="playButton_Click()" styleName="pauseSkin" />
                                   <s:HSlider maximum="{cSession.archiveManager.totalTime}"
                                                value="{cSession.archiveManager.currentTime}" id="slider"
                                                change="slider_Change()" verticalCenter="1"
                                                width="100%" height="32" />
                              </mx:HBox>
                         </mx:VBox>
                    </mx:HBox>
               </rtc:ConnectSessionContainer>
          </s:HGroup>

I see this on the console:

Is there something I need to change on the recording apps?  I'm setting archiveManager.isRecording = true and then when the browser is closed setting it to false.

The recording apps still connect using my dev username and password in the Authenticator, and the playback just uses <rtc:PlaybackAuthenticator id="auth" />.

Any help would be greatly appreciated.

Thanks,

Just wondering when you say "debug output" are you using LCCS debug util clases? As such:

Hi,

Could you provide us with some client side debug logs?  How frequent is the problem?  Have you tried restarting the playback application at least several times?  Do all your recordings fail to playback or just this one?

Thanks,

Nikola
