• TCS recorded video playback using video endpoint

  Hello

  I've deployed a Telepresence from Cisco Content Server (TCS 5.3) and met with problem regarding on how to play videos recorded by video endpoint.

  Under modify records, I don't see an option or the option 'Make check-in available for play on the endpoints '.

  Referring on the Administrator's guide TCS it is said that "If this box is not on the page of registration of amendment, a site Content Server Manager has not configured the prefixes necessary to an alias of reading E.164 and H.323 reading ID to communicate with a site manager for more information. What does that mean?

  And where I can configure the reading reading alias/H323 ID?

  The TCS is registered as SIP and H323 (E.164) on the control of VCS.

  Recorded content have been updated with the recording of "publish".

  Thank you very much for the help.

  Best regards

  Acevirgil

  You must do the following:

  Key 'Premium résolution' option must be installed.

  Record configuration, see the Site settings, such as 'Bridge', not 'Terminal '.

  

  Enter the prefixes to use for recording, and also for playback, it may not be the same.

  Note that prefix of reading options will be unavailable unless the resolution option key Premium is installed.

  Also note the playback using the SIP is not supported at this stage.

• Problems mirroring the iMac on television during video playback using VLC Player

  At the end of 2015, I bought a 4th generation (32 GB) Apple TV and an iMac with OS X El Capitan 10.11.6

  When I try to reflect my screen FRO my iMac to the TV using Apple TV video (playing through VLC) is nervous and rambling. I talked to Apple Support and they conclude that video game through VLC was the problem and VLC should perform updates to the new Apple TV. I was told that Quicktime was the only guarantee program to watch the video through, but a lot of file formats I have are not compatible with Quicktime. I know that Quicktime converts the files now, but sometimes they take forever and some files won't convert. Apple Support guy told me to another way to convert the files, but I don't remember what he says now! I did the latest VLC and am finding it's really frustrating because it was the reason why I bought the Apple TV in the first place. Any suggestions on a faster way to work around this problem? Thank you!

• Keeping the backlight on during video playback with alarm does not not with OS 4.7 round

  I am developing an app that plays the video using the alarm, like this:

  player_ = Manager.createPlayer(url);
  player_.realize();     
  
  VideoControl_ = (VideoControl) player_.getControl("VideoControl");
                  videoControl_.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE,                 "net.rim.device.api.ui.Field");
  videoControl_.setVisible(true);
  player_.start();
  

  The duration of the video is longer than 2 minutes. On OS 4.6 device such as the curve, the video plays without the screen goes black.

  However, on the circuit of 4.7 OS, screen goes black even if I try to activate the backlight on regularly, like this:

          final Timer t = new Timer();
          TimerTask tt = new TimerTask()
          {
              public void run(){
                  Backlight.enable(true, 240);
              }
          };
  
          t.scheduleAtFixedRate(  tt, 0, 240000 );
  

  The integrated application of Media Player can play the video even without the screen going dark.

  How can I avoid the screen of goes black on device OS 4.7 during video playback using VideoControl?

  Thank you.

  Now works with this change:

  t.scheduleAtFixedRate(  tt, 0, 24 * 1000 );
  

• .Flv VIDEOS don't play do not smooth

  A heavy project of Captivate generated video was created in heading 4:

  * 18 snow all this, with the total size coming to 90.7 MB .flv videos

  * Using Captivate, as looking for interactivity - there is also a menu, so users can access to whatever section they would watch/use

  When you access the project online:

  (1) the charger will quickly up to 100%

  (2) shows the preloader image I inserted

  (3) the user clicks play and the first slide with video games...

  The first video is freezing / move quickly along the timeline. Also, you can't access the other sections in the menu. While I'm not too worried about it, my priority is for comfortable vision for the first video. I'm assuming that freezes in the first video, etc. because all of the project has yet to fully charge. How a work towards this solution? I tested the time of loading, change of 10%, 20%, 100%, but the video is still sometimes freezing / moving quickly along the timeline.

  What rate do you use when you re - encode the video? Also, make sure that you use the ON2 VP6 codec.

  Try and play with the bitrate. Set it to 400 and then see if you are satisfied with the result. If it isn't put at 500, 600, 700 etc until you find a good compromise of size and quality.

  Any help?

  Here is the code for the component. I hope there is nothing odd about that. I have included my contact information at the top. Please send me an email me or Adobe PM if you have questions or comments about this code. Hope this helps someone. It took me a good while to tinker until I found this.

• GAL/jumping images when executing 3 flv videos Netstream.

  Why do I not Lagie jump video images during the use of Flash CS5 and 3 flv videos Netstream. If I play only 2 videos they work well. It is not a CPU or memory reaches max. Videos are for download locally (cached anyway).

  Conditions:

  Windows 7

  Flash Player 10

  With or without hardware aceleration - same experience

  More than 2 videos of netstream

  CPU i7

  8 GB RAM

  GeForce GTX 650

  Windows Flash (no browser) application / Windows Projector (tried too)

  Result:

  Videos all the laggie and jumps frames

  What I want:

  -Magic way to fix the lag
  -Alternative to load the video (with cue point of control and search)

  CODE:

  3 x MovieClips containing:

  var vid:Video = new Video (640,1080);

  this.addChild (vid);

  var nc:NetConnection = new NetConnection();

  NC. Connect (null);

  var ns:NetStream = new NetStream (nc);

  vid.attachNetStream (ns);

  NS.client = this;

  NS. Play ("someVideo.flv");     10 MB of video

  Problem/Bug fixed in Adobe Flash CS6 windows player!

  Thanks for your help.

• Get a FLV in a loop to a specific image using Netstream (as3)

  To preface this my AS3 knowledge is quite new. As long as the thread titled readings, I try to get an FLV to play through its entireity and loop and then back to a specific image and keep the point constantly proofreading. After much digging, I found a video tutorial using AS3 that worked! Here's my current situation even though I can't find the right code to be inserted to make the loop video back on the image I want. The FLV just stops and go back at the end of the video. Here is my code so far:

  var video:Video = new Video(1980, 1020);
  addChild(video);
  
  
  var nc:NetConnection = new NetConnection();
  nc.connect(null);
  
  
  var ns:NetStream = new NetStream(nc);
  
  
  var meta:Object = new Object ();
  meta.onMetaData = function (meta: Object)
  {
            trace(meta.duration);
  }
  
  
  ns.client = meta;
  
  
  video.attachNetStream(ns);
  
  
  ns.play("All.flv");
  
  

  In the end, the video should play throughout an only on the first load and then looping back to frame 319 and play towards the end and loop back again in order to frame the 319 infinitely. I think I'm almost there, I just need help in getting my code works appropriately. I've done this before by using "gotoAndPlay()" but the loop is not seamless so it gives one pause seconds before looping back. I hope using a function of Netstream that this will be resolved. I'd appreciate any help!

  You can use:

  Video: video of var = new Video (1980,1020);

  addChild (video);

  var nc:NetConnection = new NetConnection();

  NC. Connect (null);

  var ns:NetStream = new NetStream (nc);

  ns.addEventListener (NetStatusEvent.NET_STATUS, netStatusF);

  NS.client = this;

  video.attachNetStream (ns);

  NS. Play ("All.flv");

  function onMetaData(obj:Object):void {}

  trace (obj. Duration);

  }

  function netStatusF(e:NetStatusEvent):void {}

  Switch (e.info.code) {}

  case "NetStream.Play.Stop":

  NS. Seek (2);

  break;

  }

• How to change the rendering used for video playback in Windows Media Center Version 6 engine

  I usually use other media players, but I would like to first of all using Windows Media Center. However for the moment video playback is not good because of the weird colors (everything is displayed in black and Red instead of normal colors). When you use other media players, I use the Haali rendering engine which gives good results for video playback.

  Can you tell me how to change the rendering used by Windows Media Center?

  Also, I noticed the same weird color effect in Windows Media Player 11.

  Hi Woobee,

  1. What is the brand and model of the computer?

  2. what graphics card use on the computer?

  If you are using an Nvidia graphics card on the computer, in the Nvidia Desktop Manager, you will find an option for saturation to ensure it is set to 100%.

  And if you are any other graphics card on the computer and search for a similar option for saturation.

  If the previous step fails in Windows media player, so be sure that the hue and Saturation are defined by default.

  1. click on the arrow on the tabplaying , point to enhancements, and then clickcolor picker.

  2. do one of the following:

  1. to return to the default color, click thereset link.

  Also, make sure that the video settings are set by default.

  1. start the playback of a file.

  2. click on the arrow on the tabplaying , point to improvements, and then clickvideo settings.

  3. click onreset.

  Check also in Windows Media Center if the

  1. on theStart screen, go to tasks, click settings, clickgeneral, then Visual and sound effects.

  2. undercolors ensure that Windows media center standard is enabled.

  Turn off Visual and sound effects in Windows Media Center

• Video playback HTML5 on Android, after the "back" button is used.

  Hi, I'm looking to create an app that plays the video online, using the HTML5 video tag. I have to support Android and have a problem on this platform. My app OK video online games when the application is first started, but if you exit through the back button and then restarted, the video will not play again. I have to "force stop" the app before it will work again. If I exit the application using the home button and restart, the video is very well and reproduce again OK. This behavior occurs if I'm playing a video hosted remotely or locally hosted video. The MP4 video format, I have tried all other formats at the moment. Can someone tell me what I am doing wrong? I guess that the needs of the "back" button a kind of reset or clear-up to the release of the app, but I can't find anything about it!

  I tried to catch and disabling the "back" button event, but that doesn't seem to work at all, maybe because I'm using the Ionic framework and do it in the wrong place. But in any case I don't really want turn off if I can help it.

  I have KeepRunning = false in my file config.xml.

  I am currently using PhoneGap Build, CLI 5.2.0, 4.1.1 Android on a Samsung tablet.

  My code (I am disabling the button full screen via CSS):

  <video id="vidStart" class="videoDisplay" controls="controls" webkit-playsinline>
                  <source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
  
                  Your browser does not support the video tag.
  </video> 
  

  Thank you, Andrew

  Using plugins in your application? If this isn't the case, you can consider using the Plugin of crosswalk (https://www.npmjs.com/package/cordova-plugin-crosswalk-webview), in this way, that you're not having to deal with the glitches of web view frustrating that occur on different versions of Android.

  Also, when this problem occurs, you see anything on your machine (adb logcat) console?

• Windows XP, when the use of twitter can not play more error clips vid 'her browser doesn't support video playback', but if I take the Utube link can play w/browser

  Most imbended videos in Twitter doe not play, if I pop the link out and find on youtube, he plays very well. All in the same browser of Firefox on my old Win. XP machine. Seems to be worse, suspect it has something to do with HTML5 but don't know how to check or update to a good player. And maybe a few interactions w/twitter how to isolate. even before trying to start the video see 'this browser does not support video playback' through the image of the video in twitter mssg. THX

  See the new response below on the use of the plugin Adobe Primetime play video Twitter and respond with your experiences.

  Oh, Yes, still the headaches...

  On Windows XP, Firefox is unable to decode MP4 media. On newer versions of Windows, it can use Windows Media Foundation, but Microsoft has ever released for XP. Thus, sites that have begun to use HTML5 with MP4 media video player - and do not automatically switch to a plugin like Flash when necessary - do not work in Firefox on Windows XP.

  The last time I tried to find a workaround solution was in May and I gave up in frustration: video look a problems with Firefox.

  I hope someone else can take a new look.

  In the meantime, you can:

  • complain to Twitter
  • Look for any new modules that might help: https://addons.mozilla.org/firefox/extensions/

• How can I control a FLV video using exhibit main bar (not FLV skin)?

  I need to have the ability to play/pause a FLV video on a slide with the bar of main games.  Research showed me that in previous versions, there is a checkbox "synchronize with project" which allowed this.  I don't find this in version 8.  Is there another way to do this?

  Hello

  Welcome to the Adobe Forums

  Try to insert the video like video instead of event video synchronized slides,

  Then down below it will be an option to distribute video through the slides and you can select Slide n to n (where n is the number of slide).

  Hope that this will serve as your need.

• Need to flv video to stop once loaded

  Hi, I created a document that has 3 buttons. When everyone is pressed action happens... loads a movie, jumps to the next section, plays the video. The problem I have is when I click on the button image, my video playback and stays. The film should play only when the movie button is selected, and then deleted when you press another.

  It may be possible to indicate to the video controller to stop once loaded, but I do not know the command. The way the movie is imported, the controllers are integrated in the wrapper, but I don't know how to stop playback of the movie.

  Any ideas? As much detail as poss please! My film is called movie.flv, but the instance is called vid.

• I can zoom the flv video, playing in my swf?

  I can zoom the flv video, playing in my swf?

  Hello

  I have a FLV video that is related to my SWF file (he plays inside a flvplayback component in my movie). I would like the flv to zoom (because it plays) when the user will fly over to it. Is this possible? I was able to "Create a motion tween" on it so that it plays in edit mode , but when I preview the it, the flv just stay the same size.

  
  I did this zoom with symbols/shapes (using the preset of 2d-zoom movement), but I wonder how I could do this on a flv. I need the video to play as the transformation changes so I can't zoom in an image that looks like the video and then swap for the actual video when it comes to actual size.

  
  Thanks for any help.

  Thanks Kglad.

  I found a good explanation step by step to this process of Somascope (you need to create a movie clip on the flv playback to interpolate actually component):
