Debug a video conferencing application (How?)

Hi,
I am developing a video conferencing application and would like to know your opinions on efficiently debugging such application if I am alone.
Thank you

Well, if you are alone you can still have two computers and have a conference with yourself.
You will need a group of volunteers to help you test it in any depth.

hi!

Creating video conferencing application?.

hello, im a newbie in JMF. How should i design a video conferencing application that uses less ports for transmitting audio and video streams? since i have read in the API that there is a separate port to be used for audio and video. and what comes into my mind. the use of ports may increase since more users can come in and join the conference, and also interact with the conferencing. Thanks. I would like to hear a lot of response from people who have already created such application.

Hi,
Already set audioReliable & videoReliable false on publisher & player nestream.
Still the lag is there. Is there any latency buffer settings anywhere ( on server which each peer copies?)

IOs video conferencing

Is it possible to create a video conferencing application using Adobe Air / Flex for iPhone and iPad ? There is a sample code available on the net on how to do this on Android. Does this works for iOs too ?

Yes its possible.
Adobe® Flash® Media Server is a real-time media server that delivers adaptive bit rate video on demand (vod) and live video to Adobe® Flash® Player, Adobe® AIR™, Adobe® Flash® Lite™, Apple® iOS, and Mac OS®

Video Conferencing and Port numbers

i am currently developing a video conferencing application with JMF and the problem i have in mind is, if ever i would like to add more client on the video conferencing there is also an exponential increase of the use of port numbers?... how can i resolve this issue... Thanks..

Hi I actually work in the same... my question is... How do i to avoid use of 20 port numbers

Says my computer does not support video conferencing?

Just recently whenever i tried to do video chats it tells me my computer does not support video conferencing? How can i fix this?

In the Video Menu open the Connection Doctor and go to the Capabilities tab.
This may give you more info about which things iChat currently thinks it can do and will tell you why It thinks it can not do certain things.
If it says Low Bandwidth against some items you will need to do as Defcom says and alter the Quicktime > Streaming speed (System Preferences > Quicktime > Streaming) to 1.5Mbps and restart iChat to see the new Speed.
Also check in iChat menu > Preferences > Video section that the Bandwidth Limit drop down is not set too low. (Ideally here it should be set to NONE unless you are Comcast or Road Runner) Certainly don't use 100kbps.

Video Conferencing in Air 3 for Android/IOS

Hi,
We are in the process of creating a Video Conferencing application for Android and IOS devices, the app would be published on Android and IOS market. I have some quires related to using Air 3.0 for the development:
For Android devices Front facing camera is supported only in Air 3.0, but can we assume Air 3.0 would be officially available by end of this year?
Would this feature available for all Android 2.2 and above devices?
Can we use Flash Media Server/any other streaming server for video conferencing?
I have read in some of the post that Apple store do not allow video streaming with RTMP, is this true? Is there any work-around to use streaming video from within Air app for IOS?
Thanks in advance!

I used milkmangames ANE. (50$), because i didnt want to fork the code for each os.
http://www.milkmangames.com/blog/tools/
It was "easy" to set up (quotes: as easy as something complicate can be).
Consumables, or One-time-purchases worked out of the box, but restore, subscriptions and auto subscriptions (like newspapers) had bugs like hell and were unusable.
Also check out here for some free stuff (wich propably works as well as the comercial, "supported" stuff, stupid-me)...

How to debug a Mobile client application

Hi,
How to debug a mobile client application on the laptop, where we dont have any .NET 2003 application installed. (not an MDW)
If we get any error on the application, which could be a UI error on laptop, and if everything is working fine on the MDW, is there any way to debug the application on Mobile client?
Also, please provide me links or tips on how to debug the mobile application, on MDW as well.
Regards,
Praveen.

Hi,
to be able to debug on a local machine you would need at least to install the UI/BOL class files and the project files and make some local settings.
But anyway on all clients there should be the same MSA installation like it is on the MDW so in case of an issue it is normally caused by local (inconsistent) data.
I would suggest to access the laptop IDES database by changing your MDW odbc settings and perform the debug session on the MDW.
Debugging in VB .net is similar to VB6 but you have to notice that changing of the code is NOT possible when being in debug mode.

Wolfhard

HT201303 how to downloading videos music applications in my iphone from itune ?

how to downloading videos music applications from itune to my iphone

How did you get it onto the phone in the first place? You had to have synced it from a computer if it wasn't purchased from the iTunes store. You should still have it in your iTunes library...
Other than for items purchased from the iTunes store, media sync is one way, computer to iPhone. There is no supported method of getting other music off of the phone to a computer. If you google, you may find some useful utilities that will help.
If the media resides on a different computer and you're changing the one you are going to sync with, just back up the iTunes library and transfer it to the new computer.

How to make video chat application smarter ?

Hi all,
   I am implementing a video chat application which is working fine in high bandwith, but it is not working well on lower bandwith (200Kbps - 500Kbps). Please help me to over come the above constraint. Please find the video resolution details as below:
     1) Video resolution : 640 x 480 (24fps , KeyFrame interval 15) -- publishing
     2) Video resolution : 320 x 240 (24fps , KeyFrame interval 15) -- Playback
The above two are freezed. The following are the required to achieve
   1) If bandwidht is low show an alert to the user
   2) Detect speakers are not connected to the machine
   3) Detect download / Upload speed of network
Please help me to achieve the above.
Thanks in advance.

If you're sending keyframe intervals at every 3 frames (unless you meant seconds?) you're using way too much bandwidth. Nobody can really tell you the "perfect" bandwidth for those settings because lossy compression works on the hope that "some" part of the video will remain the same frame to frame.
With lossy spatinal compression it analyzes the previous frame and the current frame looking for differences. If you have a person chatting in a room where nothing behind them is moving (no objects, people, tvs, etc), the bandwidth will be very minimal. With a normal keyframe interval set at "96" I would wager you could get away with an acceptable picture at 450kbit video, 23kbit mono audio. 320x240@24 same 96kf interval, just half it to 225/23.
If the chat user is in a very busy environment behind themselves then these settings will be far too low. In a very busy background at 640x480@24f 96kf you could spike over 1mbit just in video and still see plenty of compression.
If you did either of those and set your keyframe interval at "3", double the bandwidth at minimum. KF interval at 3 is saying every 3rd frame, or 8 times per second, send a "full frame" worth of data. That's way too much. In the highest end video I even put online I never go lower than once per second in extremely busy videos, unless I need seriously granular seek on HTTP progressive video.
FYI the 23kbit audio comes from the SPEEX codecs quality setting on the Microphone:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/Microphone. html#encodeQuality
That'd be setting:
_micPhone.encodeQuality = 7;
You might want to do yourself a favor and give the user simple controls to adjust their own settings. A video bandwidth/quality slider, same for audio. Behind the scenes just ramp up the bandwidth. The user can choose what works for their specific situation without you needing to find a magic formula.

Video Conferencing using JSP

I am working on a interactive application whereby i can communicate with my peer for the purpose of elearning. Some of the functions i need to do is to interface video conferencing, live chat, live application sharing. All this to be real time.
Anyone any advice on how to go about do it?
Urgent advcie needed! Thanks!

I don�t know about the video stuff, but I think that it is possible to use an applet for the chat, and filesharing.

Video conferencing through Flex2

Hi,
I am a newbie to Flex and wanted to know whether applications
like video conferencing, audio conferencing or chat are possible to
be developed in flex. If yes how could it be developed. Kindly
suggest me some tutorials or sites from which i could get the
required help.
Thanks and Regards

I'm a newbie too and found this site...
http://mx.sys-con.com/read/223822.htm
It covers how to set up an application where you can see
yaself in the web cam and I think also stream the cam image through
a flash media server...although not sure.
Managed to get my cam image working fairly easily and
embedded in the application window which is the main thing though.
Not totally sure how you would go about getting the other person's
camera to appear on the same screen though...if you find out I
would love to know.
Good luck!

Video Conferencing Samples

I've been playing around with FME/FMS as a potential video
conferencing server. It appears to have some potential for our
needs. The lag looks good but it's hard to tell how well this is
working when the video previews are the size of a postage stamp. I
am currently using the sample_videoconference application. Does
anyone know of any other sample video streaming apps for FMS that
has larger video preview so that I can get a better feel how well
fms performs when using large res video, say 640x480 or larger?
I am not currently a flash programmer and in order to
evaluate larger video resolutions it looks like I'll need to muck
around with programming a flash app. What do I need to program an
app for fms?

Hi, thanks for replying. I have the following in the policy file but it still doesn't work (the syntax may be wrong).
grant codeBase "file:c:/localhost/wwwroot/vcapp/-" {
permission java.security.AllPermission;
I'll be kinda reluctant to use such open security in a production environment tho.
I might have another play with the policytool now...
