I work with cmoynihan and perhaps I can shed some additional info.
1. The streaming videos we are having problems with are NOT flash based videos. They are H.264 streaming (not download style) videos. I had infact already tried that option and it had no effect on our problem. The "Enable Flash" option is unchecked by default. and is not selected on our machines.
2. Different from the first poster, we are not seeing a logo with a question mark. What we are seeing is a "connecting" message on the bottom of the status bar with the "Knight Rider" blue dots swooshing back and forth in the viewer window. The video never connects, no errors ever come up. If left alone, this will stay this way forever, connecting.
3. Our office is made up of both Windows XP & OSX Tiger computers. Only some of our OSX systems are effected. It does not appear to be hardware specific, as the problem exists on a range of iMac G5s, PowerMac G5s, & iMac Core Duo machines. All with the same software updates except for the PowerMac G5 Dual 2.0. which has not yet updated, to the latest iTunes or Quicktime but suffers the same issue.
4. Here is a link to some videos we are having issues with.
To compare, I went to Apple's latest streaming Special Event. That video plays perfectly fine.
5. Those same unplayable videos, viewed from the same office, using the same network backbone, play perfectly fine on other machines with the same hardware. Specifically a Mac Pro 8 Core & an iMac G5 1.8 play perfectly fine. Both with the latest software updates. All of our OSX machines have the OS Firewall turned OFF.
So none of the videos on this page work for you?
Are you getting the same "connecting" symptom as we are? What machine were you trying this from? If the symptom is the same, can you test to see if you can view the special event video from apple quicktime?
I've been trying to troubleshoot this issue all day... It seems every lead i get which i explore, i find some factor that voids my theory and brings me back to square one. I've gone from wondering if its a software issue, to a web site/server issue and back to software...
To let you in on a little hint, that video page is our own. I personally create the streaming videos and upload them to a streaming server which is operated by our IT department. I have no idea what kind of hardware the server is on, which makes troubleshooting a PIA from time to time. Only recently have we had a rash of streaming problems.
We first suspect a QuickTime bug that is blocking them from playing. However, why would it only affect some of the systems when they all have the same software installed? And yet its not system type specific.....
I had a friend who is outside our network try our videos and she was getting the same problem/ symptoms. However, when i had her do the special event video test, she couldn't play that either. So that kinda voids that test..
Still beating my head against the keyboard to figure out why some of our own machines can play our own videos while some can't........ Don't know if i should be looking at the server, our building firewalls, the quicktime software itself or some other wild card source......
As an update for any future reference:
After more investigation from home i found that the problem was not OS specific, where here at the office only our OSX machines were affected. My home Windows XP machine also had the exact same issue and yet could play the special event. That actually helped in directing where the source of the issue was.
The next step, A few guys from our IT department who actually run the web site & streaming server hardware came down and hopped onto one of our affected machines. What they found was interesting.
They logged into the server and was able to trace each time a computer requested a streaming video. while on another affected computer we selected one of the videos. The request log showed up in the trace but the server identified the machine as a Windows NT machine instead of a MacOS machine. One of our OSX machines that works fine did indeed show up as a Mac OS machine. So this looks to be the source of the problem. The server is thinking it needs to send a WIndows Quicktime version to the client who is in fact not windows. OSX Quicktime apparently can't see what its being sent. Its just waiting for the info from the server, who has not sent back any kind of error. The client and the server both think that everything is ok when its not.
We were unable to test the same for a windows machine, since all the ones we had in our department were working correctly. As of writing this, we are still unable to fix the issue because we are unsure why the server is falsely identifying system types. Still working on it...
I am having exactly the same issues. It first started a few months back...but then oddly sorted itself out - as of last night it started it again. It seems to be any visual or audio streaming no longer loads and instead has a Quicktime sign, greyed out slightly with a question mark. For example I can't view videos on youtube.com or listen to music on the Standalone players on myspace.com. Very annoying.
I've run into this problem as well but I found a simple fix that seems to work.
For me it was happening only on computers that had Firefox (I have 184.108.40.206), Quicktime 7.2, and an nVidia video card, though others seem to have slightly varied results.
Changing Quicktime preferences (Enable Flash, MIME or File Type settings) does not resolve the issue. I've tried changing nVidia driver versions (163.44, 163.75 beta) to no avail. I'm now back to the current forceware release 163.71 from nvidia.com.
Uninstalling QuickTime completely fixes the issue, but then you don't have Quicktime, which is not an unacceptable fix.
What DID fix the issue was this (steps 3 and 4 may not be necessary for everyone):
1. Uninstall Quicktime 7.2
2. Install Quicktime version 7.1.6: http://filehippo.com/downloadquicktimeplayer/?2607
3. Re-install Flash Player: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
4. Restart the computer.
Flash objects will now display normally, and the "Q" icon with the question mark "?" will no longer occur on sites like youtube.com, last.fm, and so on.
I know this doesn't resolve the issue with Quicktime 7.2, but as far asI can tell from my research, there is no actual fix for this issue that includes keeping Quicktime 7.2. If there is, I'd love to read it.
As of now, my best guess remains that this is a bug in Quicktime 7.2.
Please let me know if this fix works for you or if you've found other fixes.
