Live event delay when the TCS/WinMediaServer multicasts

Hello

We are implementing a new infra composed by a DMM + SnS + TCS. The goal is to use the CHT as a 'Live Encoder"which is doing well.

Since the latest version of the SnS 5.2.3 there is now an integration of the CHT in the menus of the SnS (see attached doc).

We have followed the configuration and it works but since it is a LiveEvent target to be seen by all THE EMPLOYEES of my client, MUST use multicast.

He becomes more complex because it seems, with the multicast to be used for multicast announcement .nsc file...

The problem is when configuring for multicasting, the point of publication which is created dynamically in the WinMediaService part, begins with 5 seconds delay, and we lose the first 5 seconds of images!

Can you imagine a CEO who wanted to talk to all employees, to be not heard when saying "employees dear Good morning '?

For my client, it is not acceptable, and since this feature on SnS/TCS is described at the point of being ALIVE, it must the departure of the first image sent.

Someone would have faced the same issue, and is there a way to "force" the publishing point in the WinMediaService to be "open/started" immediately?

P.S.:

With unicast in fact we had the same problem, but we have created a workaround solution by creating a fixed publishing point always started and referring to a folder where an initial video (actines as an introductory video, saying "The Live will start soon") was present in how to read the flow immediately when the real stream live from TCS was available.

Multicast, because this obligation to use the announcement .nsc file, it is not possible more to apply this workaround.

=>, is there another possible workaround with the multicast solution, in order to ensure that the workflow starts immediately?

Hello

I plan to do a similar deployment as you did. I'm a little curious if you found a solution to your problem of delay when the TCS multicast stream?

  • Software HP C4380 printer causes delays when the computer starts.

    I don't know what triggered the problem. I had unplugged the printer and reinstalled. Now, when the computer starts, it hangs for 2-3 minutes seeking a device to the USB location 0. That remove the HP software solves the problem. I installed with the latest HP drivers and tried to use only the printer drivers without the scanner software. If I avoids the HP software, Windows installs with a Jungo win driver that causes the same result. It could have been an update of my Windows XP Home SP3 in the meantime I demolished the printer and reinstalled, but I can't follow any other changes.

    Now the printer is useless because of this problem. HP forums suggested disabling a program of tracking of HP under Services.msc, but who has also failed to solve the problem. Any suggestions?

  • Live Meeting crashes when the application sharing or desktop

    Hello

    My company, IT made me update my operating system of the old, reliable XP to Windows 7. Since that time my Live Meeting does not work correctly. I can set up a meeting, I can connect to any other meeting, but I can't share an application or a desktop. When I do this, the application closes without reporting an error. Interestingly, at this very moment, my desktop theme returns to that standard.

    I have also a system error asking me to save and open a launch.rtc file, but I have seen that there is a fix for this in the FAQ that I will apply. I don't think that this is related to my major problem.

    HE have already uninstalled my Live Meeting installed back again, reinstalled all the add-ins, downloaded all the latest fixes and patches of the MS web page, reinstalled my MS Office. Nothing helps.

    Google told me that someone already had this problem somewhere in the world, but no solution has been provided.

    Help, please. In my work as a Live Meeting is a key application that I use...

    Thanks in advance!

  • Recording Live event on FMS

    I have the same problem of SGF and F4V format.

    I want to archive the event live at the same time and do I record live in F4V format on the onPublish event.

    It comes to main.asc codes:

    [code]

    fragments of live stream

    var = Stream.Publish liveStream ("f4f:" + streamName.name);

    liveStream.record ();

    liveStream.play (streamName,-1, -1);

    Create archives (f4v) for on demand

    var vodFile = Stream.Publish ("mp4:" + StreamName.name + ".f4v");

    vodFile.record ();

    vodFile.play (streamName,-1, -1);

    [code]

    So when I use the h264 in my event source when the FMS create f4v, F4V file 320 kb (f4v is not growing) and save only 5 seconds of my event anyone my event online is more than an hour.

    But when I'm not using h264 if source my F4V file is correct and record videos 1 hour of the live event.

  • App background stops when the screen turns off

    I wrote an Android app with a Service that receives events from the LocationService and the accelerometer and always try now to wear 10 BlackBerry. Tests on a Z10 STL100-2 10.1.0.4181

    Once the unit has remained unchanged for some time, the location listener is not registered, in order to save energy, and re-recorded a trip again.

    Don't worry, this can be disabled via the visible activity. But it must continue with the last State (start/stop) after the reboot.

    I even magically figured out how to add additional permissions for the manifest of BAR: "_sys_android_autostart_service" and "run_when_backgrounded".

    But as soon as the screen turns off, my application stops working. No location or accelerometer case being received. Turn on the display again, everything back to normal.

    It is meant to be a question about the accelerometer, but I could not find in the tracker.

    So my questions are:

    -Is it possible to port Android continue to receive events location when the screen is off?

    -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

    -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

    -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

    -Finally, this would be possible with a native application? (I could port the port iOS... lots of fun...)

    Thank you very much for your help!

    PS: If it's of any interest: I use the plugin V1.6.1 Eclipse/ADT to package and install the bar.

    As reported here as well (and I'm sure in other places)

    http://supportforums.BlackBerry.com/T5/Android-runtime-development/accelerometer-turns-off-when-Scre...

    I'm working on a deal in the next version, similar to what we're doing with location requests (in other words, activate us the background mode if your app acquires a partial wake lock).

    Edit:

    So my questions are:

    -Is it possible to port Android continue to receive events location when the screen is off?

    (Yes, but you must hold a wake lock).

    -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

    (For the moment, no, but I'll change that, so it behaves like location.)  Mind you, this could be used to work on old revisions of the software until the native sensors team added a background of sensor mode which is disabled by default and must be explicitly enabled).

    -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

    (There are a lot of thing that matters if your Services happens to run or not, which is not limited to, but includes the number of applications already running and the status of the device memory).

    -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

    (No, it's a native thing.  Your application is already technically without head)

  • what event fires when one end of captivate?

    Hello

    I am a web application developer and I work with Captivate. I'm not a creator of captivate myself, just a programmer, so I don't know the first thing about Captivate (though I am working with someone who does). I wonder if there is an event that fires when the captivate is done - in other words, when the user clicks on the button 'send' on the last slide, after which there is nothing more for the captivate to do.

    My friend the designer Captivate says that the Send button is wired to an event handler in the CPM.js file. The script is named "assessment_Pass" and we located the CPM.js event handler. However, I can't work with this. I can't manually handle small javascript that Captivate generates, especially when we offer hundreds of captivate files and store the update. I need to work in javascript in my Visual Studio project. If I could know what event is triggered (if an event fires) when the captivate is done, I can then hook up a javascript event handler in my development environment.

    I found this list of Captivate events (they are actually for the Interface API Captivate that I prefer to work with, but will any event), but none of that ' s I tried seem to draw.

    Any help is very appreciated.
