Adobe Connect Supported Video Input Resolution Option Questions and Answers

An interesting question came up that others may have: What are the supported video input resolutions for Connect? I am testing a Matrox MXO2 Mini that allows me to send a variety of different resolutions through a USB shim that can be used in Connect. I have tried a number of resolutions that will either not show a full frame of video or no video at all. Can I get a list of the supported video input resolutions?

Answer:

For 4:3:

160×120
320×240
640×480

For 16:9:

214×120
427×240
854×480

Another question came up on the same topic that will be of interest. Similar to something Hippasus might ask Pythagoras: If there are three supported resolutions per aspect ratio why are there four settings for video quality under video preferences?

video-quality.fw

Answer: Apart from Video  Resolution, there are other parameters as well which define the video quality such as Frames/sec and Video Compression Quality. These four settings have different combinations of these variables:

                                           Resolution                      Frames/sec                Video Compression %

High                                      640×480                               20                                                           90

Standard                              320×240                               10                                                           80

Medium                               320×240                               8                                                              75

Low                                        160×120                               4                                                              70

For the 16:9 aspect ratio, the settings are the same as their 4:3 counterparts. For example, if 4:3 resolution for any quality setting is 320×240, then its 16:9 counterpart will always be 427×240.

214×120
427×240
854×480

VoIP Bandwidth and Microphones

When using the Nellymoser codec, one microphone might produce more bandwidth over against another. Nellymoser accepts five different microphone rates values: 5, 8, 11, 22 and 44. Each of these rate values consumes bandwidth of roughly double its value. For example the 8kHz setting consumes roughly 16kbps and 11kHz setting consumes roughly 22 kbps. The default rate value is 8kHz. This may vary depending on the sound capture device in use.

The Flash Player microphone reference documentation reads:

“The default value is 8 kHz if your sound capture device supports this value. Otherwise, the default value is the next available capture level above 8 kHz that your sound capture device supports, usually 11 kHz.”

It is possible for two different microphones to consume different amounts of bandwidth.

In case of the Speex codec, it has a fixed sampling rate of 16kHz. Speex allows control of the quality by offering us 11 different encoding quality options. See the following reference table :

 

Speex NellyMoser
Quality (EncodeQuality)Mic rate is fixed at 16 Bandwidth(kbps) Quality (Mic Rate) Bandwidth (kbps)
0 3.95 5 11.025
1 5.75 8 16
2 7.75 11 22.05
3 9.80 22 44.1
4 12.8 44 88.2
5 16.8
6 20.6
7 23.8
8 27.8
9 34.2
10 42.2

 

Adobe Connect supports three Speex settings:

  • Fast : Encode Quality 4
  • Good : Encode Quality 6
  • Best : Encode Quality 8

Increasing the encoding quality will increase the quality of the stream but will also require greater bandwidth. The Speex codec is optimized for voice and also includes voice activity detection that allows it to reduce bandwidth.

Adobe Connect 9.3 Concurrent Learner Licensing Updates

Adobe Connect 9.3 Concurrent Learner Licensing Updates

As we released Adobe Connect 9.3, we began to more accurately track Concurrent Learner licensing usage (i.e., licensing of the Adobe Connect Training Module), with reporting available in the “Reports” section of Adobe Connect Central to provide specific usage metrics.  With increased accuracy of concurrency measurement introduced in version 9.3, you may reach your concurrency limits more quickly due to this change.  Here is an FAQ around this update:

Connect Meeting remains active after the Meeting is over

Issue : Connect meeting shows active after the Meeting is over

Environment : Hosted and On-premise

Reason : If the host just closes the Meeting browser by clicking the X in the upper right side of the add in or browser, then the Meeting will remain active and will wait for all users to leave the Meeting room; it could wait for up to 12 hours before closing the Meeting room. Keeping a Meeting open this long runs risks that could affect the Connect server’s ability to martian Meeting state.

Meetings that remain active and in process will appear as active in reports. End the meeting by clicking on Meeting >End Meeting. If you click on Meeting > End Meeting then session is ended for all the users currently in that meeting room and all users would get message that the meeting has ended. This triggers the Connect server to save the state of meeting and end the supporting processes. This is safe since it ensures that the meeting is ready for next session with all the content which was used during the last session.

Hosts should select the  End Meeting option instead of clicking the “X” in the upper right of the browser or add in. Notice also that in the case of multiple hosts, one may choose to Exit Adobe Connect as well. See the GUI options under the Meeting menu highlighted below:

Exit meeting 2

 

Meting 2

NOTE : For PPU Accounts, if a Meeting host exits from a Meeting clicking the “X” in the upper right of the browser or add in, instead of Ending the Meeting , the Meeting will continue in a billable mode and the customer will  continued to get charged until the Meeting is ended by the server timeout.

PDF document does not upload into Adobe Connect

Problem: Adobe Connect could not process this document for viewing. (Either the full document does not upload or some pages of within a document do not upload)

NA5

Environment:

Adobe Connect Hosted/Licensed

Resolution:-

Use the “Sanitize Document” Feature to get rid of all the following types mentioned in the image attached below. Depending on the version of Acrobat you are running, you may need to install a trial version of Adobe Acrobat Pro to use this feature.

Using the Connect Meeting Whiteboard on Mobile Devices

Whiteboard features on Mobile are not OS dependent, rather, they are device dependent. While whiteboard content display is available on phones, whiteboard authoring is supported on tablets.  This is completely independent of the OS and applies to both iOS and Android.

The screen size is the primary mitigating factor; traditionally even the best phones have been too small to be used for effective whiteboard authoring: Pixel dimensions and resolution on phones have limitations that do not affect tablets. More specifically, while smartphone users can view the markup objects drawn by both tablets and desktop users, the following editable whiteboard feature are available on tablets:

  • drawing with the pencil tool or pen
  • the arranging object tool
  • the rectangle, ellipse, star and cross
  • the highlighter
  • move objects
  • delete objects
  • advance slide
  • undo
  • hide/unhidden menu
  • the line tool
  • single arrow, double arrow and 3D arrow
  • check mark

Note: The green pointer must be enabled by the Host on a computer. Mobile devices can display the green pointer.

Duplicating an Adobe Connect AEM-based Event

Here are some troubleshooting tips that will help you if you see problems when attempting to duplicate and an Event:

Request Not Processed –

rnp

You will find this error message pattern in the log files:

[10-20 16:44:33,196] https-8443-4987 (INFO) Exception thrown

java.io.FileNotFoundException: \\connect.mywildurl.com\ACPwurlprod1\content\65123440\766567822-1\output\.snapshot\CONNprod1_2014-09-09_08-00\cutest_pygmy_goat.jpg (The system cannot find the path specified)

The first thing to do if you see the message “Request Not Processed” is to:

  • Go to the event
  • Re-upload the images for that event
  • Then try to duplicate it again

You may look in the log files for the following error message pattern if the problem persists but that will most certinaly solve it:

Keep in mind also that when duplicating an Event, even though the email options for any Event allows you to customize and save iCal email messages for Email Templates, nevertheless upon duplicating an Event there is only certain information that is copied/duplicated and customized email templates are not included.

Note also that duplicate Events are handled as new events in the database; there is not any specific flag that differentiates duplicate Events from original Events.

Flash Player Crashes in Meetings in Safari or Firefox on Mac when Volume Keys are Invoked

Flash Player Crashes in Meetings in Safari or Firefox on Mac when Volume Keys are Invoked

This issue is resolved in Flash Player version 15.0.0.189 scheduled to be released on Oct.14th

The following configurations are among those affected:

  • MacBookPro Retina 2012
  • OSX 10.9.5 and 10.9.4
  • Flash Player 15.0.0.152
  • Safari 7.1 (9537.85.10.17.1)
  • Firefox 31.0

In the mean time, prior to the release of the fix, there are two workarounds:

  • Don’t use the volume keys on the MAC when in a Meeting in the Flash Player
  • Use the Connect Meeting Add-in to join Meetings instead of the Flash Player

Make Certain that Content is Replicated Across All Servers in a Connect Cluster

Occasionally a specific piece of content may be intermittently available in a cluster. It could be Presenter or Captivate published on-demand content or even content within a Meeting room. Sometimes in these cases, the content published on one server is not replicated to all servers in the cluster. There are a few quick things to check:

First: Note that with Adobe Connect 9, the installer includes a cluster option. If you begin with a single server installation and expand later to a clustered environment by adding a server or servers, you will need to manually make the following change in the /appserv/conf/server.xml file in order to enable communication over port 8507 among clustered servers. It is prudent to double check this in the server.xml file after installing even if the cluster option was selected during installation:

<Executor name=”clusterThreadPool”
namePrefix=”cluster-8507-” maxThreads=”150″
minSpareThreads=”5″/>

<!– Define a non-SSL HTTP/1.1 Connector on port 8507 –>
<!– Used for HTTP access for intra-Cluster communications. –>
<!– Equivalent to JRun CLUSTER_PORT –>
<!– Uncomment for clustered deployments
<Connector port=”8507″ protocol=”HTTP/1.1″
executor=”clusterThreadPool”
enableLookups=”false”
acceptCount=”100″
connectionTimeout=”20000″
URIEncoding=”utf-8″/>

Second: Test the 8507 port communications on each server: From a command prompt on each server, type netstat –an|find “8507” and check to be sure that 8507 is active and listening on each.

netstat -an|find “8507”

netstat.fw

Use telnet to test connectivity on  8507 between Connect servers. Use telnet to check both IP and machine-name as well.

telnet server-machine-name 8507

telnet 8507.fw

Note: The machine name appears to the left of the FQDN under the Connect Servers Setting on port 8510 locally on any server in the cluster; here I have artificially designated them as server1 and server2.

serversettings

Be sure to check telnet connectivity from and to every server in the cluster:

telnet 8507.fw

If the IP works with telnet and the machine-name does not work, it may be necessary to add entries in DNS or add hosts files to each server:

etc-host.fw

Check the software-based firewall on the server to see if it is potentially blocking replication traffic:

netsh firewall show config

firewallsftwr.fw

win-firewall-svc.fw

Note: Connect does not support dual stack ipv6 and ipv4 on the same server.

Note: If problems are noticed in the Meeting rooms, check port 8506; it is used for Meeting communication among the servers.

Third: Examine the Connect logs: Look first in the debug.log under the \logs\support directory and search on the string: cluster-  If replication is taking place, you will see this repeating cluster- entry logging the replication activity. Absence of these log entries will indicate that replication is not working:

[10-1 12:00:00,009] cluster-8507-630 (INFO) CLUSTER Sent file: \7\xxx-xxxx\fcs-meeting\public\all\224_XXX_4.fso 9978 bytes 12 ms 6371 kbps to: server1

cluster-debug.fw

Check for any error messages in these replication log entries. Search also for the word lucene. If you see a preponderance of lucene lock errors, contact Adobe Enterprise Support: entrsupp@adobe.com and provide a log snippet to expedite diagnosis.

Also check the error.log files for the entry  CLUSTER_CON_BROKEN

2014-10-02 15:28:48 “Server server1 unable to reach server2 on port 8507 to perform cluster operations.” CLUSTER  CLUSTER_CON_BROKEN

Fourth: Check the timing of active anti-virus scanning of the content directories \content\7\ on each server; compare the directory sizes on each server to see is there if a significant size delta. Antivirus software can impede replication in manner that is not uniform across servers; active scanning of the content directory during replication may lock the content files. Active scanning after hours or during a window when publishing is unlikely is prudent.

Fifth: Check the updater page. Make sure you are on the latest patches servers-side. http://helpx.adobe.com/adobe-connect/kb/connect-90-patches.html Keep in mind that 9.2 is a full installer and not a patch. For full installers, use LWShttps://licensing.adobe.com

These steps will solve most replication problems that you encounter. If problems persist, contact our  Enterprise Support Team.

Avoiding Inaccurate Completion Reports when a Meeting is Part of a Curriculum

When a meeting is part of an Adobe Connect Curriculum, a trainee can click on the Meeting and complete the Meeting task prescribed in the Curriculum prior to the Meeting taking place.

curr-mtg.fw

 

One way to help manage this is to choose the Meeting options to block Meeting access illustrated in the screen captures below:

block-mtg.fw

 

block-in-mtg-menu.fw

block-in-mtg.fw

The Meeting access options may be inconvenient to use, so here is another option to add a Meeting to a curriculum, while at the same time restricting the ability for a trainee to complete the Meeting task prior to the Meeting taking place:

Step one: The first step is to set a date and time under the Meeting properties. Make sure the date and time correspond to when the Curriculum task takes place. Note that this date and time has no effect on when the Meeting can be used. It is strictly an administrative tool to help with Meeting invitations and has no effect on when the meeting can be opened, Meeting persistence, etc. In this example I have set the meeting to October 22, 2014 at 12:45 for 1 hour:

meeting-date-time.fw

meeting-date-time-1.fw

 Step two: Download and unzip the Meeting Curriculum Wrapper: https://platinum.adobeconnect.com/lmfc/default/launchMeetingInCurriculum.zip

Note that it is zipped twice to facilitate download:

cur-unzipped.fw

Step three: Identify the Meeting sco ID from the Meeting that you wish to add to the Curriculum and copy it to the clipboard:

The Meeting SCO is in the Meeting URL:

meeting-sco.fw

Note: You can also see the Meeting sco ID by pasting ?mode-xml at the end of the Meeting URL and reading it from the output:

meeting-sco1.fw

Step four:  Edit the index.htm in the unzipped LaunchMeetingInCurriculum folder by pasting in the Meeting sco ID from the Meeting that you wish to add to the Curriculum. Use your favorite text editor such as notepad or textpad. Where the index.htm reads,  Enter the SCO of the Meeting, Virtual Classroom or Seminar var meetingScoID_str = ‘1660065186’; change the default Meeting sco ID, 1660065186, to the Meeting sco ID of the Meeting that you wish to add to the curriculum, in the case of my example here, the Meeting sco ID is: 502114549. Be sure to save the changes:

index-sco.fw

Step five: Zip all the edited contents of the LaunchMeetingInCurriculum folder and rename it to represent the Meeting that you wish to add to the Curriculum. This will help you identify it and differentiate it from other Meetings with which you use this wrapper:

zip-contents.fw

zip-contents1.fw

Step six: Upload the edited zip file to the Adobe Connect Content Library:

upload.fw

upload1.fw

upload2.fw

Step seven: Import the wrapper from the Content Library into the Curriculum:

curr.fw

Note: Import options; the wrapper is Content and points to the Meeting:

curr1.fw

curr2.fw

curr3.fw

curr4.fw

Step eight: Test the Curriculum item; unless the time and date coordinate with the actual Meeting schedule, the pop up will deter the trainee from gaining premature access to the Meeting and skewing the Curriculum completion report:

curr5.fw

 Conclusion: With proper management and administration, an Adobe Connect Curriculum accurately measure the progress and completion of trainees. There are two ways to prevent a trainee from completing a Meeting curriculum task prior to the meeting taking place, the first is to block access to the Meeting and the second is to use the Meeting Curriculum wrapper.
