IChat audio/video btwn DSL-DSL and Cable-DSL

Let me draw this out to illustrate the nonsensicle situation.
party A: has cable modem with an Airport (DHCP) (running Tiger)
party B: has DSL with Airport (DHCP) (Tiger)
party C: has DSL with Airport (static and redistributed as DHCP) (Tiger)
A and B can chat/audio/video
A and C can also do all of this.
B and C: doesn't work at all exept for text. We both get those pesky messages about 'user is not responding' etc. The only thing I can think of is that iSight/iChat doesn't work between people who both have a DSL connection. We also tried to use the same powerbook (normally located at party C) at the location of party A and works with party B. In other words, the powerbook isn't the problem. Both party B and C can establish a connection with a public "test buddy" (appleeu3test01, appleeu3test02, appleeu3test03).
I am asking any genius out there what the heck is going on?????? If it's true that DSL/DSL connections can not communicate with each other, what is the point of having this overpriced webcam??
thanks in advance......

Ichat audio/video

I know many people have posted their issues with ichat's audio/video, but I haven't found any solutions that would help me. My problems are, every time I open ichat's preferences and try to click on 'Audio/Video' ichat crashes, you can probably guess that I also can't video chat with any of my peers, nor can I screen share. A couple of months ago I was able to, I'm not sure if there is any relation, but ever since I set up time machine through my AirPort Extreme Base Station, thats when I noticed problems. If any additional info is need to help solve my problem please let me know. Thanks for the help.

Hi,
Log on to the Airport base Station using Airport Utility (Application/Utilities).
Use the Manual Configure button.
Go to the Internet iCon/pane.
Select NAT tab
Enable Port Mapping Protocol (You do not have to set ports)
From the first part of the Internet Pane make sure any DNS server listed are copied or show in System Preferences > Network > Advanced Button > TCP/IP tab.
In that same place turn Off IPv6.
Post back with results as we may have to get you to delete a .plist to get ichat to be stable.

Minimum NAT/firewall settings for iChat audio/video to work?

I've read the docs on teh ports and firewall issues but it is still unclear to me.
I have
1. An OS X Server 10.5.2 connected to the internet behind a router with NAT and running a firewall. NAT and of course the firewall are under my control. I've opened up the iChat Server SSL port (5223) on the OS X Server's firewall. I've put a 5223 redirect on the router to my OS X Server system. iChat is configured on this system and several users have permission to use iChat. The NAT table on the router is restricted, only ports I want to serve (e.g. 25, 22, 5223) are redirected to my server, the rest of incoming connections are blocked at the NAT (safer that way).
2. An OS X 10.5.2 client behind a NAT setup in another part of the world.
3. An OS X 10.5.2 client behind a NAT setup in another part of the world.
Both clients I can manage the firewall of the client, but I cannot manage anything on the router.
WIth this set up on both systems users have successfully connected to my OS X Server's iChat server using SSL. Text chat works. So I can assume that iChat Server works, that the permissions and login is OK, that SSL is OK.
But neither audio not video works. I cannot establish an audio or video connection because the connection fails. The iChat connection log says
2008-02-21 20:49:53 +0100: user@fqdn2: Error -8 (Did not receive a response from 0x18c09b30.)
there is nothing in appfirewall.log on the client.
The clients should work OK behind NAT. But my guess is that the server needs more than what I am giving it. However, I have been unable to find out what a minimum set of NAT redirects and firewall ports open is that would enable me to let these two clients do voice chat via my OS X Server at that other location.
Any tip for information on how to set up the server side minimally and safely would be welcome.
Thanks,
G

Hi,
Several things.
1) iChat server does in fact use an SSL Login on port 5223 (Tiger does not do the SSL but is still on the same port.
This does not allow the other data on port 5220 that the Jabber side of iChat needs.
Apple Doc http://docs.info.apple.com/article.html?artnum=93208 see item 6
2) It also ignores the fact iChat uses a completely different set of ports to the A/V Chat
So an AIM Login is port 5190 in those mentioned in item 6
port 5297, 5298 and 5353 are the Bonjour ones.
That leaves 5060, 5678, 16384-16403 for A/V chats in Tiger
5678, 16393-16402 in Leopard
The pics and Table are for Panther and Tiger. See the Table at the bottom http://www.ralphjohns.co.uk/pantherports.html
The changes from Tiger to Leopard in the port Usage for A/V chats is documented here http://docs.info.apple.com/article.html?artnum=306688 (Hence the none use of port 5060 and the smaller groupfor the actual A/V Chats)
3) Check out the two server forums for Leopard > iChat Server http://discussions.apple.com/forum.jspa?forumID=1235
And Tiger/OS X Server 10.4 > Collaboration Services http://discussions.apple.com/forum.jspa?forumID=700 as they maybe other issues that I am not aware of on the Server side.
So Leopard Jabber/iChat Server needs 14 ports
5220, 5222, 5223 on TCP and
5678, 16393-16402 on UDP
Tiger needs the A/V ports to include 5060 and extend the group to 20 ports (16384-16403)
I hope this helps.

How merge audio/video for easy cropping and editing

I'm trying to build a movie by importing my audio and video clips separately from Cinematize. (This is the only solution because Imovie has a bug and shows the movie file as distorted widescreen - and transitions don't work with a .dv file) I have about 5 different extracted imports - or 5 clips. That means 5 video.mov files and 5 .aiff files
The problem is this - I want to lock/merge the audio to the video FOR EACH CLIP - not to the play head. I want to end up with several merged audio/video clips for easy cropping. Is this possible? Otherwise how do I crop the video clips and keep the audio clips exactly in sync?

Hi:
You can make your movie and export back to tape and then reimport to imovie, Then the audio will be on the actual video clips.

IChat - audio, video and screen sharing no longer work

I use ichat video and screen share to visit with family and assist with computer work. Every since .mac changed to .me, I am no longer able to do anything but text message...... I have changed ports, changed from .mac to .me logins. But still not luck. Nothing has changed with routers. Working with cable modems and DSL..... Looking for help.

Hi Bob,
The Screen Sharing through iChat and the Audio only and Video chats do not require the AIM servers other than to say your Buddy is On-line.
There is feedback from the AIM servers to say what capabilities your Buddies have.
You can see these if you look at their Info card (Click on a Buddy and use Apple key and i together)
Now if the Buddy does not show the capability then it may well be the AIM server.
But..... IF you have turned off (or it has become turned Off) either of the Camera Enabled or Microphone Enabled items in the Video menu (from menu bar) then you will not have the capability and will therefore not see other people.
One clue will be in the Buddies Menu about whether you can do One Way Video or Audio chats. If it says you can it is the AIM end.

IChat Audio/Video not happening

Three differnt people with 3 different setups trying to do an audio chat:
John: MacBook(2.0Ghz, Leopard), connected via AirportExpress, using an AIM account
Anne: MacBook(2.4Ghz, Snow Leopard), connected via a 3G USB Modem, using a .Mac account
Mark: iMac(2.0 Ghz C2D, Tiger), connected via AirportExtreme, using an AIM account
John can voice and video chat with both Anne and Mark, no problem. But Anne and Mark constantly get the Error-8. (But strangely Anne and Mark can share files via iChat just fine.)
If it was a firewall issue, wouldn't one of the three be excluded from any voice/video chat completely ? Im starting to wonder if it's the NAT/PMP issue as well, cause it doesn't seem to be an issue when connecting to the other person.
This is a snippet from the error log:
Video Conference Error Report:

Hi,
Mark should go to the set up pages of the Airport he has and in the Internet icon/Pane > NAT tab he should have Port Mapping Protocol turned On.
If he has the much older firmware I will need to see pics (again) to remind me.
The other potential issues is what modems are John and Mark using in front of the Airport base Stations ?
Are they routing modems ? Cable modems tend not to route and DSL one do.
They should not have two DHCP servers on their LAN's ( A Base station set to "Share An IP" will be doing DHCP and a routing modem will most likely be doing it by default)

IChat audio/video not working: bonjour over computer-to-computer network

My girlfriend has a brand new MacBook Pro 15". I have a 3 year old PowerBook. Both running 10.4.9 and iChat 3.1.8. We are currently sitting right next to each other, and yet have been unable to connect to an audio or video chat by any method.
To completely eliminate the router from the equation I created a computer to computer network which she joined. Both of us have our firewalls off, and both of us have our Quicktime streaming speed set to 1.5Mbps. We tried to create an audio connection over Bonjour. I got an error -7 and she got an error -8.
There are many threads reporting the same error, but most of the solutions involve changing router settings. I figured that since this is on a computer-to-computer connection there is no router involved. It would be nice to be able to get this working over the general internet, but I figure if it doesn't work in this very limited setting it will never work. Any help? Much appreciated.

Yep - did that on both computers, to no avail:
Here's the first section of the error messages from both computers. (I can post more if it's helpful.)

Hi,
Re 1)
iChat makes a Connection that is Peer-to-Peer when doing Audio Only and Video chats.
To do this it uses a method of going through NAT Devices (Network Address Translation)
NAT Is not a standard. It is a vague description of things that happen in most domestic routers to share one IP between many computers and other devices.
There are about 4 main ways of doing it See Here
Realistically iChat can be Fussy as to how NAT is done. (Some methods don't seem to "Play Nicely" together)
So you can get what looks like intermittent symptoms.
Re 2)
I am on a Leopard booted computer and my AIRPORT UTILITY is version 5.5.1
I don't have an Airport Base Station so posting a pic is useless at this point.
The older firmware I am thing of popped up a very small Window asking for the Password before giving you the main window.
The version I have lists the different Base Station it can find down the left with a manual Configure Button and a first time set up button on the right (I forget the name).
It sounds like he has something closer to my version.
The Port Mapping Protocol may be "Greyed Out" if the Device is NOT "Sharing an IP" on the main Internet icon/pane. (On the current version I believe the NAT tab disappears if this is the case).
Re the Zyxel.
Not particularly iChat Friendly as a range.
There is something about them logging in to AIM on Port 5190 on the TCP Protocol and iChat send files on port 5190 on UDP that these modems don't like (Dual use of the same port)
This may be related to Port Forwarding.
With setting up Port Forwarding you point one port to one IP (Computer) (multiple ports one at a time for iChat)
This means that other computers cannot then use those ports (ports Cannot Be Forwarded Twice).
Not all devices specify Protocols to do this but the Zyxels do seem have an issue with and for some reason this crosses over into A/V Chats.
SOLUTION
In iChat go to the Preferences > Accounts > Server Settings tab when Logged out.
Change th Login port from 5190 to 443
This port is memorable as it is below the 1024 threshold in most domestic devices (all ports below this are Open to everyone) and is used by Web Browser for Secure sites (such as Banks and the Sign-in here to post).
It is also used by some mail servers.
The Modem most likely routes.
This means two things.
1) the Airport Base Station should NOT - Set it to Bridge (Off) Mode in the drop down at the bottom of the Internet pane (Port Mapping will not be needed then either).
2) the ports need to be allowed in the Modem.
See this page
This is the instructions to access a P660R-HW T1v2 I am not sure what the difference the HW means
Do the pics look like his set up pages ?
Most likely he will have to Look for UPnP - Try the Advanced menu item.
He will not need the Port Forwarding if he Enables UPnP.
He may have set up pages that look more like these pics EQ 660 R
Here you can plainly see UPnP in the middle menu 9At the bottom)
Summary
Change port for Login in iChat
Set Base Station to Not Route.
Enable UPnP in Zyxel modem. (DO NOT use Port Forwarding despite the Links (they are just for the Pics and Instruction on how to access the device).
If he cannot find UPnP come back to us.
He may have to set Port Forwarding if it is only one computer.
As he is on Tiger he cannot do iChat Screen Sharing so that will not be so much of an issue.

Ichat audio video options for google accts

Hi,
1. I use ichat with my google account. I was wondering if I could do an audio and video chat from this account?
2. Also, if I disable my camera (in format tab), and press on the audio option beside my picture in the chat list, why is isight cam getting turned on? Shdn't it be disabled and only microphone be turned on?

Hi,
Re 1)
If you are your Buddy are using iChat with any Jabber ID including Googletalk then you can do Video and Audio Only chats. This is because no matter which Buddy List you start from iChat uses the same A/V Protocols.
What you can not do is Video chats to the PC App for GoogleTalk or to any Buddy logged in on the WebMail Google pages, both of which can also do A/V chats but uses different protocols.
Re 2)
The Video Camera is turned Off in the Video Menu at Camera Enabled and toggling it so no tick shows.
Yes when it is turned Off (Deselected) the icon next to your name should show the Audio icon (Telephone handset).
The camera will however get turned on for the Preview even if the camera is turned Off. A preview of the Audio would not "Show" anything as iChat does not allow play-through of the live sound.

Slow Audio/Video on i3 iMac and ESU1808 audio interface

Symptoms (with both 32bit and 64bit kernels):
Everything runs as expected at 96 kHz for a while and then one of the following occurs:
1) Everything slows down, so audio sounds deep and MIDI triggers are slow. In Renoise, movement through the pattern slows down accordingly, and in DVD Player the video frame progression also slows accordingly. At this point I can fix the sound by changing the sample rate (in Renoise using the preferences and in DVD Player by using Audio MIDI Setup) to another frequency and then back again. Then the same issue occurs again after a while.
2) Sound stops and there is a short burst of noise coming from the speakers at regular intervals every 1 or 2 seconds. Pattern progression in Renoise also slows as with issue 1, plus the level meters within Renoise freeze and change in time with the noise bursts. In the ESU1808 control panel, bursts come up on the meters, including on the inputs. On the front of the unit, the MIDI Out light flashes in time with the noise bursts. Here the unit must be switched off and back on to correct.
The same occurs in Cubase LE 4.
Running the unit at 88.2 kHz has caused the second issue, and running at 44.1 kHz and 48 kHz is fine.

Not quite Chris - your hospital will probably have a device or several devices distributing IP addresses connecting everyone to the network - the DHCP server. That device could have more work to do (ie number of users, traffic volume) than it is capable of delivering at speed. Using Bonjour for iChat relies on this device matching up buddies - if the device is busy you'll have to wait longer to be matched up for video chat. Ask your IT department to look at whether these devices are hitting 100% CPU - if yes that will most certainly be your problem waiting 5 minutes to connect.
Meanwhile - a separate suggestion - it sometimes helps to speed things up by reducing the number of directories your Mac looks at when searching busy networks. AppleTalk is the original Bonjour - SMB relates to communication with Windows. If performance remains unchanged simply tick them back on.
Any use?

IChat Audio/Video Delay

Hey, I recently bought a Macbook Pro and some of my friends have added me on iChat which I thought would be amazing. I've been left disappointed. The first video conversation I had was fine and seemed to work, but ever since there has been a severe delay with it. Audio in particular. When talking there can be up to a 30 second delay for the person I am chatting with to get the message leaving this feature unusable.
Any ideas what could be causing this? Also their video seems really pixelated. Is that normal? Look forward to some help with this problem! Any information could help!
Thanks in advance,
Stefan

I have been experiencing a similar problem since upgrading to 10.5. The video is about 5 - 20 seconds behind the audio. The audio is in real time. I've tried the above and checked activity monitor and there is nothing unusual clogging up the CPU. I have an iBook running 10.5 and there is no trouble with it.

Choppy ichat audio & video

Hi,
I cannot get my ichat to work properly. Whenever I try to connect with someone (we are both using Mac OS X (10.5.2), we get a choppy connection, that is the video feed looks like a bunch of pixels lagging every few seconds. Its almost like the feed is cutting in and out but the video pixels are never put into order. Also the voice feed cuts in and out. We are both using wireless routers so we tried pluggin our laptops into the internet using the hardline but it was the same story.
I'm not very computer savvy so any help would be great!!!

Tony,
Thanks for the feedback! I did what you said about the quicktime adjustment and the ichat adjustment and then i restarted ichat. This definitely helped but the picture is still choppy whenever one of us moves on the camera and the voices are also stil choppy, but ughthe pixels don't look as messed up.
I have a question for you... In system preferences/QuickTime, would the "Enable Instant-On" setting have any impact on my problem?

Loss of Audio / Video sync between browser and canvas

When I am working in the browser, the video and audio are in sync. But the moment I put the clip into the canvas, I lose the sync. I captured an entire mini DV tape and then cut it up into clips. Some of the clips are fine and some lose the sync. Any ideas? Thanks in advance.
Power Mac G5 Mac OS X (10.4.4)

You must mean when you are working in the Viewer, the sync is maintained.
If sync is lost, it is often the result of mismatched audio sample rates. For example, if your sequence is set to 48khz/16 bit and your clip is 32khz/12bit, audio can drift. It will drift even if the audio is 48.001khz.
Only DVCAM locks audio to video. Long captures using consumer equipment are particularly susceptible to drift. One strategy to avoid it is to log the clips on the tape and capture in short segments.
Good luck.

IChat audio/video prroblems

Hi.
I am unable to connect two computers to chat over AIM with iChat AV 3.
Both of us are using ibook 1.42, 10.4.6, isight, iChat AV 3. Both of us can connect to the appleu3test03 test page successfully but when we try to connect over AIM we both get the dreaded '<user> declined' message.
I have adjusted my apple firewall settings to include:
TCP: 5190, 5298, 5220, 5222, 5223
UDP: 5060, 5180, 5190, 16384-16403
The other computer has Norton Personal Firewall - I do not know what settings may need to be adjusted there.
We are both behind NAT modem/router firewalls - Netgear DG834G
Am I missing something really obvious.
Thanks in advance for any help
