Video freeze, sound only, no solution

I'm having problems with video iChat. Shortly after I connect, my
video freezes (both send and receive) but the chat continues with
sound. If I try doing anything in iChat (like quitting) I get the
spinning wheel of death. The only thing I can do at that point is
force quit the process. Since the process doesn't technically crash, I
don't get a crash log. I am running a brand-new 24" iMac G5 with the
latest version of Mac OSX (10.4.10), and all software updates. I had
been able to successfully iChat until last week, which also coincided
with the latest OSX and QuickTime updates.
I have tried all of the following:
- Switching my port to 443
- Reducing Quicktime streaming speed to 1.5 Mps
- Changing settings on iChat bandwidth limit from Automatic to anything lower.
- Creating a brand-new test user and seeing if the problem persists. It does.
- Fooling with the Quicktime transport settings (HTTP vs. UDP)
- Ran Apple's hardware test suite. No problems. The built-in iSight
camera works fine with all other apps. I can capture video from the
camera with iMovie with no problems.
- Tested hardware. Everything fine. The iSight camera works fine in all other apps.
I can even make a movie with it in iMovie.
- Did a speed test. Download 8560Kb/s, upload 923 Kb/s
I can video chat with various Apple bots. This appears to be receive
only. My insert video has frozen only once. My friend whom I have
trouble chatting with (and with whom I was chatting successfully up
through last week) chats with other people on a daily basis without
incident.
I've ruled out my ISP and my router because I can iChat with the same
friend from my wife's G4 laptop. To make things even more maddening,
I can also iChat with my wife's laptop via AIM.
I did an archive install (keeping users and settings). Same problem.
I called up AppleCare and they recommended that I just reinstalled
iChat. It worked for a few minutes, then the same problem. Applecare's next
recommended course of action is an erase install, and I really don't want to
go through the hassle of that just to fix iChat.
I'm enclosing process samples that contain error messages, first from
the "vcencoder" child process of iChat, and then from iChat itself.
Here is a sample from vcencoder while I am connected with the Apple ichat bot. Notice
that I removed dozens of repetitive threadreadstack errors in the interest of space

iMac G5 Mac OS X (10.4.10)

I just did all of the above:
Pacifist iChat reinstall
Pacifist Video Framework and Chat Framework reinstall
Combo reinstall.
Had one session of 2 or 3 minutes without freezing, though the stack errors
were still there in the processes. Then, I froze and all subsequent chats freeze almost immediately. This is driving me crazy.
Also - I'm new to the Mac world. I have a 24" Intel iMac - not a G5.
Thanks again

FCP X / Motion 5 Drop Zone Video Freeze Frames Only!

Hmmm, well, I've followed the other discussions here regarding what appears to be an on-going issue with videos not playing (freeze frame only - usually the first frame of the clip) in a Drop Zone. I'm using the latest versions of both FCP X (10.1.1) and Motion 5 (5.1). I created a video generator in Motion with 15 drop zones for use in an open for a project I just started on. These drop zones are sliding left and right in three bands across the canvas. I can't get any of them to display moving video. I've used drop zones before and had some success with getting video clips to play in them, but in this case I'm batting zero.
Has anyone found a way around this problem? I may just import the videos into Motion and render them there since this open more than likely won't ever be used for any other project; nevertheless, I'd like to be able to use the Motion 5 template as it was designed to be used.
Thanks.

The good news, Russ, is that I've made some progress! To say that using Drop Zones can be a bit quirky is an understatement! Nevertheless, your Pro Res hint seems to have fixed my issue. I've been recutting the clips from the master archived files and saving them as Pro Res 422. The file size is considerably larger that the H.264 files, but since it works I guess I won't argue that point! :-)
I need to do a bit more investigation of this next point, but it also seems as if I need to move a frame or three into the clip before inserting it into the drop zone. I had just been taking the clip and dumping it in as is. When doing that I noticed that in some cases the clip either didn't play (freeze frame) or it started at some random (or at least what seemed to be random) location within the clip. However, since I moved the start point in 2 or 3 frames (end point doesn't seem to matter) so far, at least, the clip plays every time and starts from the proper point.
I don't know if this mattered or not, but I completely deleted the library with the project and event that I was originally trying to edit to. Since it wasn't working anyway there is nothing lost and I felt it was worth starting the project "fresh", so to speak.
So far I've only re-clipped and inserted 5 of the 15 drop zone videos but for now, at least, they are all working!
Thanks again for your help and suggestions.

IPod (with video) freezes Windows XP - POSSIBLE SOLUTION

Hi everyone,
I bought a 5g 30gig iPod with video a few days ago, and immediately ran into the "iPod freezes Windows when connected via USB 2.0" problem. I read through every possible post on this website, on iLounge, on Microsoft's forums, etc. There seems to be quite a substantial number of people running into this problem, because I've been seeing posts about this all over the place.
My specific problem was that whenever I plugged in my iPod, the iPod would display "do not disconnect" and iTunes would begin to recognize it - sometimes it would reach the point where it would begin to update - and then the computer would completely freeze. The iPod would "disconnect" and be completely usable, but the computer would not respond to anything what-so-ever. I had to perform a hard restart to get the computer usable again. No error messages, no "ctrl-alt-del" saves, nothing. It would also lock in the same exact way if I just plugged the iPod in without starting iTunes (iTunes wouldn't automatically start, computer would just lock up after a few moments).
Anyway, my problem was solved through a procedure I saw in a post somewhere (I'm pretty sure it was on these forums, actually). Basically, it seems as though there is some sort of conflict between iTunes, Quicktime, and Symantec's anti-virus.
The process is pretty simple - completely turn off whatever version of Symantec you're using (Norton AntiVirus, Firewall, whatever... I'm running Symantec Corporate AntiVirus 10). Then, uninstall Quicktime and iTunes (it might not be absolutely necessary to completely uninstall iTunes - I uninstalled Quicktime and then "repaired" the iTunes installation).
This seemed to resolve the situation entirely - I've updated my iPod three times now, and charged it, with no problems. Hopefully this continue to work... !
Incidentally, I think it's disgusting that this seems to be such a prevalent problem, yet Apple so far refuses to acknowlege its existence, much less provide a solution. As a long-time Windows/Microsoft user (notice I didn't say 'fan'), I expected much more from Apple.
Anyway, good luck!

Hi!
I have the same problem, though using iPod Touch.
My PC crashes just after charging sound on th iPod sounds.
I can be loggen on or not.
I have tried the 5R's two times
I have removed SP3, didn't help.
I have updated to iTunes 8.0.1: Didn't help.
But I have an portable PC (job PC) where it is working fine, both PC's using XP Pro, english version.
So, just now, I am very dissapointed bu the Apple products (and it took me 20 years of Software Engineering before i bought something from Apple ..... )
So the stress test will be: Will Apple do anything with this ?

Mini-HDMI Port: Video OK, sound only works for iTunes

Let me start by saying, I'm pretty new to Mac so please be gentle with your answers...
I just got a new HD Samsung TV and have connected it to my Macbook Pro through the Mini-HDMI port. There are two HDMI inputs on my TV, DVI and ARC. I'm using DVI. The video displays perfectly but I'm having a little trouble with sound.
Once I went to system preferences and switched the audio output method to "SAMSUNG - HDMI" my iTunes music began playing through the TV speakers. I played a .wmv video from my hard drive; sound and audio all worked well. However, when I attempt to play anything through the Internet, Youtube, Hulu, Pandora, no sound... I still get video, and if I switch the Output source back to "Internal Speakers - Built-In" there's no problem. I don't know if it makes any difference, but I'm using Google Chrome as my Internet Browser.
I've double/triple checked the sites to make sure the local audio levels aren't being muted, and that doesn't seem to be the case. Is there a setting somewhere that references only Internet, or more specifically, Google Chrome audio Output levels?
PLEASE HELP...
Thanks

The "Front" channel isn't the same thing as the front panel. From the ALSA wiki:
"Front, Surround, Center, LFE (subwoofer) and Side (these are the names of the channels with Intel HD Audio, they may vary with different hardware)."
How many sounds cards do you have?

What are the other HDMI devices? The video card?
And have you tried googling the problem?

Video Freezes and Stays Frozen

Hello,
Every single time I use Skype my video freezes after only a few seconds. Sometimes it will unfreeze after a few minutes and sometimes not at all. I am currently using Skype 6.21 and have a logitech c270. The c270 works fine with my laptop. I would greatly appreciate any help that would resolve this issue. Thank you.

Videos freeze and distorted sound

Hi,
about a week ago i bought the HP Pavilion 15 notebook PC, windows 8-64 bit, Product number: F4T60EA#ABU
that has an intel i5 processor and ITB memory. About a few days after using it the HP support asisstant program suggested a sort of system update that led me to the HP website and i followed the instructions etc.
Unfortunately since then i have been having trouble with any videos i watch online (youtube, streaming etc). The video freezes for a second randomly and then the sound distorts and then the video goes back to playig as normal...this distortion happens every 5-10 seconds of video playing....I have tried uninstalling Flash player and reinstalling the latest version, however this has not helped. I dont really use my laptop for much accept bits of work and the internet so i ahvent downloaded anything that could possibly be the cause.
Please help!
Thank you

Hi numar96, sorry to hear that you are having issues with watching videos. I have had this issue in the past and what I have found resolves the issue is changing the Refresh Rate on the display. I have a short YouTube video that explains how to change the Refresh Rate. Please click on the link that I have provided to get to the video. http://www.youtube.com/watch?v=hzfcxcdKRKo
If this does NOT resolve the issue, please let me know.
Thank you.

Why won't videos play on my new iPad 2 14gb? They either constantly buffer, stop and I have to press play again, play sound only etc.

Why won't videos play on my new iPad 2 14gb? They either constantly buffer, stop and I have to press play again, play sound only etc.

Thanks .Ralph. The problem is only on the iPad 2only. I have an iPad 1 as well and it never had the problem. The only videos that I have tried are you tube and the tutorials on apple.com. I have absolutely no problem on either of my laptops or desktop PC's. Only the iPad 2. I am a new Apple user, so not very familiar yet with the product, but this is an absolute deal breaker for me. With Apple's reputation I was not expecting any such problems and it is beyond my skill set to solve it. Very frustrating. Again, no problem with you tube videos. I don't watch movies, so am not a Netflix member and haven't tried that yet, only you tube videos and apple.com tutorial videos. I have to watch those on my laptop. Again, I found a fix to the you tube problem. It was a link to a site. www.youtube/html5. html5 video player trial that you click on and once done, the videos on the you tube app started working great. They were doing the same thing as the tutorial videos prior to that. No such luck with the other web videos, at least the ones that i have tried. Hope this is enough info and understandable. You might check out the html5 site. I didn't thoroughly understand why, but it worked. You may understand it better. I am a proficient user, but far from an I.t. Pro. I have read Many posts with similar problems, but no simple solutions and the ones I did try didn't work. Speed tested well. Channel is set to auto and always different than neighboring networks, usually channel 11. Tried disabling QOS as suggested....no good. I am completely stumped. Any help is greatly appreciated. Thanks very much for you time and helpful info.

Videos freezing but the sound still goes on?

Any video except Youtube videos freezes/stops moving the frames as it's paused at some random point but the sound and the timer/slider/scrubbing tool/bar still goes on with the sound.
Please help!
It happens at random times, random sites and browsers. Also it happens in random places in videos too. Usually at the very first seconds though.
1-) I have tried different browsers,
2-) Tried other sites,
3-) Other resolutions and varietys of videos,
4-) Flash Player (Puffin and Photon),
5-) Resetting my internet settings,
6-) Power off and on my ipad,
7-) Googling this problem.
Steps of the problem:
1-) Can watch the first seconds/minutes perfectly.
2-) When I try to slide forward it automatically stops/freezes the visual/frames but the sound and the time still goes on.
3-) It happens when I don't slide forward too.

Hi,
Is it a Plug-n-Play or Plug-n-Pray headphones ? Have you installed its driver ? Can you see it in Device Manager ? If Yes and Yes you have to disable the internal speaker and enable the headphones using the speaker icon at the bottom right (Playback devices).
Regards.
BH

I also have Jolly's problem. I found the iMovie 9.0.9 folder and tried to launch the older version of iMove. It would not launch. I removed all of the iMovie preferences from the Preferences folder, removed iMove 10 from the applications folder, and restarted my Mac. iMove 9.0.9 still won't launch and I can't access my videos created with the older version of iMovie. Is there a way to uninstall iMovie 10 and reinstall iMovie 9.0.9?

Your Mac runs maintenance in the background for you.
Command + R gives you access to restore, repair, or reformat the drive using OS X Recovery
No idea why that was suggested.
You may have a third party video player installed that's causing an incompatibility issue.
Check these folders:
/Library/Internet Plug-Ins/
/Library/Input Methods/
/Library/InputManagers/
/Library/ScriptingAdditions
~/Library/Internet Plug-Ins/
~/Library/Input Methods/
~/Library/InputManagers/
~/Library/ScriptingAdditions
The first four locations listed are in the root-level Library on your hard disk, not the user-level Library in your Home folder.The tilde (~) represents your Home folder.
To access the Home folder in OS X Lion or Mountain Lion, open the Finder, hold the Option key, and chooseGo > Library.

Hello,
Most videos on the internet are played using the Adobe Flash plugin.
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash update and/or a malfunctioning browser plugin such as Real Player.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
* [[Flash Plugin - Keep it up to date and troubleshoot problems]]
* [[Flash 11.3 crashes]]
* [[Flash 11.3 doesn't load video in Firefox]]

I hope this helps. Let me know if not.

IPhone 5 video recording or playback video, no sound of rushing and only.

If I with the iPhone 5 receiving a video and then give it back then you only hear a noise and the actual sound only whole softly in the background.
What could be the problem, and please excuse my bad english.
thank you

The problem I found, on my iPhone back a film on it to protect against scratches. Then looked at an Apple TV and advertising because it has been shown that the back is a small addition to the Micro Camera :) and that was covered by the foil so foil away and everything works perfect.
Sorry for my bad English :(
Thanks

My mac mini only shows a steady power light and fan noise when powered up. No video or sound and no commumication with wired keyboard or optical mouse. Tried replacing internal battery and resetting PMU/SMC but nothing seemed to happen. Any suggestions?

You've already done the two things I would have suggested.
If your Mini has an internal battery then I assume it's a G4. That means you've gotten a lot of good years of service from it, and it's old enough that it's certainly not covered by AppleCare anymore, and it's probably not worth spending money trying to repair it.
You should be able to tear it apart using instructions from ifixit.com to get the hard drive out, and then put the hard drive into a nice USB or FireWire enclosure (I like the ones from Other World Computing, macsales.com) so you can transfer your data to a replacement Mac.
I hope someone has another suggestion for you.
