Video and audio (in one direction only) deteriorate after about 90 seconds

I begin a two-way video chat as normal, both parties can see and hear clearly. After about one and a half minutes of normal video chat, the person on the other end suddenly starts getting a highly pixelated image of me, and they start to lose chunks of audio from me. Meanwhile I continue to get a very nice clear video and audio from them. We usually end up closing the chat, because they are unable to hear or see me enough to continue.
The first 1.5 minutes or so is always clear, it starts after that. I always receive good audio and sound from the other party throughout the chat. I have never had problems receiving video/audio.
It happens with most (but not all) people I connect to. I am in California, and I always have this trouble when connecting to a relative in Connecticut. I have the problem again with one relative in Sydney Australia, but not with a different relative in Sydney. These are just a few examples by location.
I have repeatedly tested my connection speeds, and I have good up and down speeds - more than the minimum requirements. (My speed today is 8200 kb/s Down, 1309 kb/s up).
I have also tried:
Checking my Quicktime settings - (set to 1.5 Mbps T1/Intranet/LAN)
Bypassing my Airport modem/router, by connecting directly by ethernet to my Comcast cable modem (which has no router built in)
Replaced the cable modem with a brand new one.
Changed locations - tried it at a friend's house, still had the same problem.
So, I think I have isolated the problem to my PowerBook. This PowerBook used to do iChats really well for at least 18 months. I have been having this issue for about 5 or 6 months now. I have no idea what the problem could be. Any tips would be much appreciated.
Thanks, Martin
My setup:
ISP: Comcast Cable (Cable modem)
Apple Airport Exteme Base Station
Powerbook G4 1.67Ghz, 1 GB RAM, 80 GB HD
O/S: Tiger 10.4.10
iChat 3.1.8 (with Chax)
External iSight camera

With Comcast.
Try rebooting the Modem.
This seems to refresh the connection in some manner.
Also speak to them. They may not admit any connection management but thing may "magically" get better.

Video and audio not synchrone with apple tv after update mountian lion on macbook pro

i have a problem with my apple tv. after i bought and instaled mountain lion on my mac book pro i have trouble with apple tv and my laptop. when my laptop conects with apple tv most of the time my wifi doesnt work on my macbook but on my apple tv it stil does work. when it does work and i play a movie of my own by using itunes the first second the video and audio is synchrone but after that audio is at normal speed but the video gets behind. and i am getting sick of it. does sumbody reconize the problem and can help me with this problem?????

Same issue here- I can airplay my amazon prime library just fine from my iphone 5 but on my macbook- (mavericks, 15 inch 2013 retina with quad core i7, nvidia 650 M and SSD) it just sputters and lags.
I have noticed web video is considerably worse than local content, giving me pauses of up to 2 or 3 seconds in which video stops but audio continues in the amazon player. Youku video, however, seems relatively stable. Our subscription speed is 25 mbps, so that should be plenty to stream SD video from Amazon and doesn't account for why it would be nice and stable from the iphone, but not the mbp.
Playing light, locally hosted steam sidescrollers like Limbo is better but gives periodic drops in framerate on the Tv. when mirroring the framerate remains steady on the MBP screen.
Games airplayed from my iphone seem relatively stable, though with a noticably lower framerate on the TV than on the phone.
It seems these issues have abated considerably since yesterday's Apple TV update, but are still curious nonetheless and I'm not sure that the update yesterday was specifically meant to address those issues or if I'm just getting a time with less network interference now.
Comcast recently installed a new router/modem/phone combo, replacing our old separate modem and router setup. I'm going to test if putting the network on a different channel helps.

Video and Audio cut off in Premiere CC after Syncing in PluralEyes 3

So I sycronized this sequence in PluralEyes 3. I exported it as an XML for Premiere Pro. I imported the XML into Premiere Pro CC. When I oppened up the sequence the end off all the clips are missing audio and video. More is missing for the longer clips. You can see how the clips are blocked off. I have video from a T3i and a K-x and audio from an H4N. Running OSX Mavericks on a Macbook Pro 15in Retina w/ Nvidia 650M 1G. Anybody have a solution or know why it's doing this?
Thanks

Figured out that this happens if you import your assetts into premiere. Create a sequence. Export an XML from Premiere to PluralEyes. Sync it. Create an XML for Premiere and then import it into Premiere.
It works properly if you start in PluralEyes with your assetts and then Impot the synced XML into Premiere. Its a shorter and smarter way to do it anyway. I was trying to do it the way I used to on PC.

Ichat video and audio is not working only with one friend

Hi there,
i used to video-chat with my best friend every other day. We both have OSX 10.5.8. Maybe 4 weeks ago suddenly we always get an errorcode when calling each other. Sometimes it says the other one doesnt anwer but he gets an error message. He and me can still video chat with all our other friends!
Only in between us it doesn't work. Both ways don't work (who ever calls). We both have an iMac 21.' with intel prozessor.
Text-chat works!!
If another friend calls both of us, we can chat the 3 of us together!
Any suggestions?
desperatly Mike

Hi,
This has been an issue now and then for all versions of iChat
http://www.ralphjohns.co.uk/page15.html#CertainBuddy
The most common reason is setting Port Forwarding in a router to open the ports and leaving On the DHCP Server.
This means that now and then the Computer IP may change and the Port Forwarding may require you "point It" at one IP - which the computer no longer has meaning the ports are not open.
The next is the way some devices actually Do NAT (Network address Translation).
There are 4 main ways with cross over between them as well.
This may raise it's head if you or your Buddy have updated the Firmware to your router.
I would check System Preferences > Quicktime > Streaming is at 1.5Mbps at both ends.
I would double check the routing settings at both ends.
UPnP if you have it is "Better" is that it allows Multiple computers (IPs) to use the same Ports so you don't have to turn Off the DHCP Server in the router.
Thomson-Alcatel can have symptoms like this due to the way they handle SIP data.

Mpeg2 DVD VOBs Video and Audio into QuickTime ?

How can I read the mpeg2 VOB files from some DVD that we created into QuickTime Pro with the MPEG2 playback component ?
We have an app that does video and audio processing built on QuickTime. After the processing is done the result is written to an mp4 file using QuickTime export. We now have to be able to read DVDs that we create into this app (QuickTime), and after processing we must se the QuickTime export option to create the mp4 file. These are not commercial DVDs and are not copy protected. I'd like to just be able to read the mpeg2 video and audio directly into QuickTime but I haven't yet found a good way to do this. Here is what I have tried:
1) I can read individual VOB files with QuickTime, but I don't get any audio and I need all the VOB files as one.
2) I have used MPEG Streamclip to open the DVD VOB files and exported the demuxed mpeg2 video and aiff audio. Both files open together in QuickTime but since the total size of the video is over 4 GB the video and audio are off and drift more so throughout the video.
3) I used libdvdread to read the DVD and create a single MPEG2 file. This can be read by QuickTime but I don't get any audio. From what I understand this is muxed video and audio which QuickTime doesn't understand, but is playable by VLC.
I think I could probably ulibdvdread to read the VOB files into a muxed MPEG2 file, then use ffmpeg to convert this to a very large DV stream, then import that into QuickTime, but there has to be a better way than to do the lengthly and large file size conversion to DV which is not a format I ultimately want.
Before we go and write our own, I'm looking for a simple way to read the mpeg2 video and audio from a DVD format directly into QuickTime and preferably something that can be integrated into our app and not use another commercial stand alone app.

OK, I can't tell you what we are doing, you'll have to trust me that it's for a very good cause. I'll simplify the use case as an example. If I can do the following we'll be OK:
1) Read video/audo files from a DVD that we created
2) Open these files with the QuickTime Player, click on Export to Apple TV to create an output file.
I'd rather not do an interim conversion of the video data (like use a 3rd party app to convert to mp4 first and then read into QT, but I'm considering a conversion to DV) because that could seriously hurt the apps effectiveness. I also can't use another app (MPEG Streamclip, HandBrake, VisualHub, etc.) to do the conversion.

HT1535 I wish to sync my iPad and PC on one direction. Just copy PC contents into my iPad. Is there any iTunes option that sets this feature ?

I wish to sync my iPad and PC on one direction only. Just copy PC contents into my iPad. Is there any iTunes option that sets this feature ?

How does this approach sound:
On the iPad, go to Settings > General > Reset > Erase All Content and Settings
That will strip your iPad of all its information.
You can then sync your iPad to your computer using your computer's iTunes.

Making QtWebkit support HTML5 video and audio

For those who don't know, HTML5 enables most current browsers to play videos and audios without the need of any plugin. QtWebkit supports this feature, so browsers using it such as Rekonq and Arora should support it too. However on Arch Linux this does not work outside of the box.
I've tried to make this work and made a little progress, and I'm wondering if anyone has made similar attempts, have suggestions, or are willing to try this out. What I've done basically is to compile Qt with Phonon, and then remove the Phonon files when building the package, so that it uses the Phonon that comes with KDE. I included the PKGBUILD below, and you just need to copy the extra/qt directory from abs, and override the PKGBUILD or apply the patch.
I also installed phonon-vlc-qt from AUR, which according to this post contains some fixes to support HTML5 video/audio. However neither this nor the default gstreamer backend works for me. With vlc the vidoe doesn't play, and with gstreamer the browser crashes. To try different backends for Phonon, open KDE's System Settings - Multimedia - Backends, and use the Prefer and Defer buttons.
Some links for testing HTML5 video and audio:
http://html5test.com Only uses JavaScript to ask the browser if it supports the feature. What I've done does make these tests pass.
http://html5video.org
http://youtube.com/html5 Join the beta, and then open some youtube videos, and look for HTML5 in the player's control bar

Use a minidisplay/HDMI cable for video:
http://www.cnaweb.com/6-mini-displayport-male-to-hdmi-male-cable.aspx?gclid=CMbn pNem57wCFRQS7AodzDQACg
A 2009 MBP does not support audio via HDMI so you will have to tap the Audio Output port. Use a 3.5 mmRCA plugs and tap the RCA audio inputs on the TV with a cable such as this:

How can you use one NetStream to publish video and audio from another NetStream in AS3?

Let's say one of your client programs in AS3 is able to receive live video and audio from a NetStream and play it on the screen. How could you make it also take that video/audio stream that it's receiving, copy it over into another NetStream, and publish it elsewhere? I need to know how to do with this regardless of whether RTMP, RTMFP, or some mixture is involved. The reason why the stream needs to be relayed this way is a real long story, but it's necessary in this particular case. Thanks!

RTMP is TCP, which has higher overhead and latency because it guarantees packets are delivered (handshaking, causing latency and overhead). It also doesn't allow you to share connections directly between clients forcing the server to do all the work.
RTMFP uses UDP, which is a choice protocol for streaming video because it's the opposite. It's lossy which decreases latency and overhead from no retransmissions and most importantly (in some applications) allows you to connect directly from one Flash Player to another Flash Player (p2p) so the server overhead is dramatically reduced. The server is only required to negotiate the initial connection and then it's up to the clients to continue to facilitate that.
How you code your one to many or many to many relationship broadcast network will be based entirely on which of those you choose.
URLStream is very common to use in p2p. Here's an older Adobe article on p2p and an alternate quick old video tutorial (FP10) as a quick simple example of p2p over RTMFP you can view the source of.

Hi, please help me When I render my project in IDVD, video and audio runs properly, but when I burn it in professional quality and burning is finished there was no audio on the last two chapters, one audio is attached to the clip and the other one is from itunes, pls help

Hi
My first two thoughts
• Shared to Media Browser - BUT as Large or HD - try Medium !
• audio from iTunes - use to go silent
- in iTunes
- Create a new PlayList with needed audio
- BURN this as a standard Audio-CD (.aiff) - NOT .mp3
- use the files on this CD in Your Movie project - I ALWAYS DO - and only use .aiff ever - never .mp3'
My notes on this:
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
Minuscular - - 176x144
Mobile - - - - - 480x360
Medium - - - - 640x480
Large - - - - - - 720x540 960x540
HD - - - - - - - - 1280x720
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
6. Ed Hanna
Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies — except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format — that I have noticed.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it

I have quicktime player 7.7.2. A relative video clips from his phone. Previously they downloaded with both video and audio. As of Sept. 30 only the audio downloads, yet Quicktime still plays older saved video/audio clips. Help?

I have Quicktime Player 7.7.2. A relative has been sending video clips from his phone since June, and until Sept. 30 both the video and audio would download. SInce that date only the audio downloads, yet I can still open and play the older saved videos just fine. I tried looking at QuickTime help info available. One place said something about purchasing Quick Pro for use with 7.7.2, but if I need that, why can I still open older saved videos? Thanks for any help.

I'm adding more information:
in Finder, my iMovie folders are all visible and accessible. When I click on a clip from iMovie Events folder, Quicktime opens and plays the clip. ALL my video is not missing - it just isn't showing up in the Event Library!
This happened all of a sudden, while I was working on iMovie project (on both computers).
All my Projects are intact, and play when I open them.

Help lost audio on one session only and other faults occurred

Hi for some reason I have lost the audio on one session only .in multitrackAll other sessions play ok /The tracks in this session play in edit and also show as playing on the meter bar in multitrack but no actual audio heard. Even more annoying is that now if I click anywhere on the task bar whilst playing a session it stops. I am not aware of making any changes in Audition but vaguely recall possibly hitting another Key whilst tapping the space bar , Any advice greatly appreciated thanks.

If the transport is running, and you can't hear anything, then at least your audio device is still connected. If it wasn't connected, you wouldn't even get the transport to start. On that basis, I'd suggest having a careful look at the mixer, and seeing if you've accidentally done something like muting the Master channel, or accidentally knocking the fader back to zero. Under the circumstances you describe, this is pretty much where your problem's got to be, I think, especially if it's only on one session.

(To Replace http://discussions.apple.com/thread.jspa?threadID=406147 if Accepted. )
How do I get Video and Audio Chats with PCs ? iChat FAQ 3 (Updated 7/12/2008)
Applies to iChat 2.x, iChat 3.x and iChat 4.x to any version of AIM on a PC before AIM 6.1
This piece is designed for those trying to connect Mac to PC for Video and Audio chats. Any iChat version Panther and up.
Glossary For This FAQ
This bit is designed for clarity.
Video is the sending and /or recieving of pictures and sound.
Audio is the sending and or receiving of sound only.
One-Way is the ablity to start either an Audio or Video chat from one end to a receipient who can not match your capabilities (or Vice Versa)
What is needed
At the Mac end
A Mac running OS 10.3.x and iChat AV ver 2.1 or 10.4 plus iChat 3 or Leopard and iChat 4
A DSL/Cable/Fibre (Broadband) connection of at least an up link speed of 256kbs.
An AIM , @mac.com or MobileMe (@me.com) account name.
(hosting Multiple person Mac to Mac AV chats requires higher specs and broadband uplink speed).
At the PC end
1 PC running windows XP (home or Pro). THIS A MUST
The AIM Standalone Application, currently at ver. 5.9 at this link. AIM (the Site) now call this version Classic and it cannot be Installed On Vista
Note: there is also Trillian which has a Pro version for $25 that can also Video and Audio chat. The Basic version just Texts and Audio Chats (AIM does not Audio chat)
Some need the aimrtc12.exe file from Here Mostly Earlier than XP or Pre Service Pack 2 XP versions of Windows
Note: It has been noted that this file is now apparently included in Windows XP after Service Pack 2 and above.
An AIM account/screen name (AOL or Netscape count as well)
Service Pack 2 info. This info will allow the PC user to enable AIM thorough the XP Firewall. The Windows Firewall did not exist as such before this
Between both of you.
At least one camera (Mac end)
A sound input device (the camera, if it has one is ok)
Your Buddies screen/account name in each others Buddy Lists
Other tweaks
For some people, using AIM on a PC, may also have to make sure their preferences (properties) are set in the AIM Buddy list, for their camera and /or Mic. (Tuning at Message 570)
This is an icon button lower right on the Buddy List marked "Prefs" (AIM 5.5). This leads to the Preferences. Drop down the list until you read Live Video. Click on this. In the new window that opens click the button that says Tuning Video and Audio. Follow the instructions in the wizard that opens up. Access in AIM 5.9 for this is in the My AIM menu at the top of the Buddy list and then Options
To Start
You should now be able to chat to each other.
If each of you has a camera it can be full Video , as described in the Glossary at the top.
To start from the Mac end, select (highlight) your Buddy with one click. His camera icon should be dark. Click on the icon near his name or the one at the bottom of the Buddy List. (You do not have to start a text chat).
To start from the PC end you need to start a text chat, then select the Video icon at the bottom of the chat window.
If one of you has a camera and the other has a Mic then you will be able to chat One Way but have sound will be both ways.
To start this type of chat from the Mac end you will have to go to the menu item "Buddies" and drop down to the item "Invite to One Way Video Chat"
To start this from a PC follow the directions in the pargraph above. You may need to change the tab to the incoming Video at the back of the two to see the Video. These tabs are added when the Video chat starts and the front one normally states you do not have a camera and shows a connection to buy one.
It is also possible to chat One Way if the other person does not have a Mic: replies will have to be typed in a Text chat.
No Camera and No Mic will cause iChat to End the chat with "No Data Received for 10 Secs"
Summary
For any sort of sound to a PC using AIM, (Talk in PC or Audio in iChat) the Mac will need a camera. The other person can have a Mic and then live chats with sound both ways and Pictures (Video) the other.
NOTE: At This Time It Is NOT Possible to Audio (sound only) between Mac & PC with AIM & iChat
Trillian Basic can Audio. Trillian Pro can Video and has a bigger picture and can do Full Screen.
Another explanation of the set up can be found Here about AIM 5.5 but is transferable.

A DSL/Cable/Fibre (Broadband) connection of at least an up link speed of 256kbs.
An AIM , @mac.com or MobileMe (@me.com) account name.
(hosting Multiple person Mac to Mac AV chats requires higher specs and broadband uplink speed).

1 PC running windows XP (home or Pro). THIS A MUST
The AIM Standalone Application, currently at ver. 5.9 at this link. AIM (the Site) now call this version Classic and it cannot be Installed On Vista

Some need the aimrtc12.exe file from Here Mostly Earlier than XP or Pre Service Pack 2 XP versions of Windows

Below the pics is this quote
What do I need to use Real-Time IM?
You and your buddy need to be using AIM® 6.8 or higher to use Real-Time IM. Unfortunately, Real-Time IM does not yet work with older AIM clients, iChat®, or AIM® for Mac®.
