Viewing streaming video through Share Pod

Through several Connect presentations I have tried to share a Windows Media Video (.wmv) and have had spotty success. One time it plays just fine and all participants can see the video playing through my shared Windows Media Player. (And I mean all participants, not just one or two).  A second time the same presentation is given, the .wmv file can be HEARD, but the video portion of the screen is black.

I'm thinking there is an issue with a firewall? or perhaps the capabilities of the hosting computer's video card? Are there any minimum system video card requirements for Connect?

I have several presentations coming up that will require playing different multi-media files (.mp3, .mov, .wmv) and sharing multimedia type programs like Audacity, MovieMaker, iMovie etc. and I sure would like to get consistent results. Any help is appreciated!

Gratefully,
Penny

Re: Viewing streaming video through Share Pod

Hi Penny,

Windows Media Player does this purposely to restrict users from copying video through a secondary output.  Even without the black screen issue, sharing video using a screen share isn't typically ideal.

The best way to share multimedia in a Connect meeting is to upload the audio/video file to the room itself instead of trying to share your computer screen.  This will guarantee that users will all have the same experience and the sound will come out of their own computer speakers.

You can import an MP3 natively into a Connect room.  Use the share pod to select a document from your computer - then select the MP3 file.    Unfortunately, you can't do the same thing with a windows media file.  Video needs to be in FLV format to load it into the room natively.

Adobe Flash (the full program - not the free flash player) has a video converter bundled with it.  If you don't have Flash, there are free and commercial products that can convert video's to FLV format (just search Google).

Hope this helps.

Re: Viewing streaming video through Share Pod

Thank you Alistairlee -
Although I'm not happy with the answer per se -- I need to use Media Player -- I understand the resolution. What is really weird is the fact that it worked sometimes, but not always. Is there any rhyme or reason for that? [For example, I use a website that has streaming videos (for education) when I am sharing that website, and then play an embedded, streaming video, it *sometimes* will play in Connect. If I could figure out what the variable is, I could attempt to make it work all the time...

What about using a different .wmv player? Are they all as restrictive as Windows Media Player?

Thank you for your time and help on this. I appreciate it!

One reason for intermittent success is the varying availability of bandwith. Connect prioritizes what will be transmitted based upon BW. I believe audio comes before video. Adobe has a best prctices paper on it

Thank you Alan, I will search for that best practices paper to see if it offers more insight. Thus far it seems I can use a different video player (open source) and it works more consistently. Can't say *why* but it does!

Thank you for your time!

Re: Viewing streaming video through Share Pod

If you take your hardware acceleration in windows down to none or within Windows Media Player, it should allow your attendees to see the shared video instead of the black screen.

Go to your desktop, right click on it and go to properties, and select the settings tab. Go to Advanced, click the troubleshoot tab. Take the hardware acceleration slider to none.

OR

In Windows Media Player go to Tools, Options, performance and take the video acceleration slider down to none.

make sure you make the changes back to normal as these settings can tax your CPU a little more than normal.

Hope this helps!

This is exactly our situation.  We need to be able to demonstrate, in real time, how to use audio applications such as Audacity, Logic, and Reason.  But there seems to be no audio passed from an app when screen sharing it in Connect.

While I have read Mongerryan's workaround in this forum, that does not seem to allow the presenter sharing their screen to talk through their mic at the same time.  Both are an absolute necessity for us.

We can not prepare all our demos in Captivate ahead of time, as our need is to be able to answer student questions, in a live format, about how to do a process in the app using a screen share to demo it.  Not to mention that we are all working on Macs, so Captivate is out.

Sure, cranking the computer speakers and getting that to carry across the presenter's mic might work, but the quality would be poor.  Creating an elaborate mixer setup with both computer sound and presenter's mic feeding into a common source to be selected in the Microphone setup wizard would be a little out of reach for most of our faculty, and possibly prone to user errors.

Any help in this area would be appreciated.

you should know that Windows Media Player will do  this purposely  because they want to restrict their clients for copying video with their secondary output option.  Even without the black screen issue, sharing video using a screen share isn't typically ideal.
