Dashboard widget with streaming video breaks after upgrade to Mountain Lion

Hi.  I recently upgraded from Snow Leopard to Mountain Lion.  Under SL, I had an OS X widget that was a web clipping of a streaming mpeg image being produced by a Linksys/Cisco WVC54GCA web camera.  When I brought up the dashboard, the OS would start streaming the data from the mpeg filename, which looks like "hostname.com/img/video.mjpeg". 
After upgrading to Mountain Lion, I noted that the widget never fully loads, indefinitely displaying a "Loading Clip..." mesasge.  After deleting and re-adding, I can still get as far as adding the web clipping to the dashboard at the right dimensions, but there's no content.
Unfortunately the camera unit doesn't provide for the display of HTTP access logs, so I can't see if there's an issue there, but my understanding is that if I can display the image in a Safari browser, it should work just fine in Dashboard too.  (I did make sure that, where needed, the username/password for accessing the video are included in the URL.) 
I did sniff the network traffic between my system and the camera host, and show that video traffic starts flowing between the two as soon as the widget is brought up.  So, it's almost like the widget doesn't know when to stop "loading" and start "displaying," perhaps because the HTTP request is never truly "done."
Can anyone speculate if something may have changed in Mountain Lion affecting the ability of web clipping widgets to display streaming video?
Thanks,
Chris

Hi James
I have exactly the same problem with the same "Loading clip" then blank.  I have been trying a lot of stuff to get this working, but haven't had the chance of sniffing the network traffic as you have done.  By reading what you said about the traffic seems to be flowing without the picure being displayed makes me even more puzzled by this.  I never had a streaming video while  I were using Snow Leopard, but I had a still-image, as I also do now in Mountain Lion.  I recently began to research for a way to display the video.cgi MIME image that my camera produces, and I've also concluded that this should be an easy task for the dashboard web clip function; the video does display in safari after all.
I suspect that our cameras uses the same built in webserver solution written by a "Steven Wu".  Cheap webcameras frequently uses his script with MJPEG (stream of JPEG pictures) to avoid the expensive licenses of using other video codecs.
I read this a bit down at this site: http://channel9.msdn.com/coding4fun/articles/Everyone-Loves-Babies-Webcams-and-M otion-Detection
Have you come any closer in your research?
I have started to think that maybe I have to write a dashboard widget on my own to accomplish this.

  • Problems with my second monitor after upgrading to Mountain Lion

    Basically I have a Mac Pro 8-core with two video boards (2 x NVIDIA GeForce GT 120 512 MB) connected to two monitors. After upgrading to the Lion Mountain, 90% of the time when I start my MAC the second monitor doesn't show it image, keeps in full black screen, what puzzle me is, I can see the mouse arrow on it, so its alive, but its in black, than I have to restart the computer over and over again until it finally make the second shows it contains.
    Have anyone experienced the same problem?!

    Hello Carlo!
    Sorry but I don't understand which part of my question is not clear. I've been to the Apple Store, they asked me to bring my 20kg Mac Pro and both 24" inches Eizo monitors to central London to have it checked. Well, honestly, this is impossible, is an invitation for an accident.
    Is just unbeliavable that no one has experienced my problem, looks like I am the only one person with two monitors using the Lion Mountain.

  • How to sync kalendar with goolge calendar automatically after upgrading to mountain lion?

    Hello,
    after upgrading to OS X Moutain Lion on my MacBook Pro the calendar is not automatically syncronised with my google caledar even the account is set up properly. It seems the calendar has no contact at all my google account. It still works on my Iphone and Ipad.

    When I purchased a new MacBook Pro a couple of months ago or so, I used an external firewire drive that I use for backup purposes to transfer my iTunes library from my PowerBook to my MacBook Pro. I copied the iTunes named folder at Home > Music and with iTunes quit on my MBP, I placed the copy in the same location on my MBP at Home > Music.
    I transferred nothing else and my iPhone was not erased of all iTunes content the first time I synced my iPhone with iTunes on my MBP. 3rd party apps are stored in a Mobile Applications named folder located in the iTunes folder.

  • After upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer or even off my iTunes library

    after upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer, love film or even directly off my iTunes library. in each case, all i get is a black screen and no error message.

    Hi, i had the same problem and tried this,
    Somehow iTunes is tied to Safari. Try this:
    Someone mentioned to clear all website data and history in safari, stupid but it was either this or the below that fixed it
    or this,
    Disable Wi-Fi Networking Services
    Many users have reported that they’ve solved their issues by disabling Wi-Fi Networking under Settings > Privacy > Location Services > System Services. This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.
    Please let me know if it works.

    after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

    Hi Memalyn
    Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
    My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
    If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
    Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
    Let us know what you find out, and if you manage to get your space back.

  • After upgrading to mountain lion, my ip camera video feeds time out

    I've been using my iMacs for a few years to monitor six ip Camera video feeds.  The cameras I use are both FOSCAM and AXIS brands.  I've used a few third party software solutions to do the monitoring, but I could also always use Safari to access a camera at a time by putting that camera's IP address in the address field and logging into the camera. 
    After upgrading to Mountain Lion, my video feeds started timing out when using DComplex's IP Camera Viewer, so I thought initially it was strictly an issue with that third party app.  However, I then logged into my cameras using Safari and they timed out as well.  Similarly, when using Axis Camera viewer, my video feeds would time out.  It seems as whatever the issue, it does not affect Firefox, because I can still login and monitor 1 feed at a time using that browser without any timeout issues, and for some odd reason, the FOSCAM only program uFoscam works, but the problem for me with that app is that it only works with Foscam, and not the Axis cameras (besides it's an inferior program to IP Camera Viewer in my opinion as well).
    Has anyone encountered this problem and come up with a solution?  I'm thinking it's some sort of plugin or video codec problem, but it's well above my paygrade to figure it out.

    I'm having the same problem with both my Vivotek wired network camera and Panasonic wireless network cameras. At first I thought this was an issue with the video framework in Mountain Lion, but if Firefox is working (I haven't tried it yet), it sounds like it may be an objective-c video library that has been changed. It's possible Firefox is using an objective-c interface that calls an objective-c function that isn't called by Safari or IP Camera Viewer, etc., (possibly a function that is on its way to be deprecated) or Firefox could use it's own library that directly calls the video framework.
    Could be the Mountain Lion objective-c framework has a buffering issue.
    Since this is occuring in both 3rd party software and Apple software, it sounds like it's an Apple issue. 3rd party applications typically utilize the Apple Developer objective-c frameworks to access video frameworks/libraries (for example, MJPEG). Thus, contacting 3rd party developers may not solve the situation (unless they can figure out a temporary bandaid--possibly figuring out the video framework call that Firefox uses and patching their software to do the same (not a simple task), but could still provide more feedback to Apple via their developer status.
    Has anyone attempted to record from their cameras via iMovie or Final Cut Pro X HD? I will try mine later tonight to see if it records the hanging. If it does, then it's looking more and more like Apple's the culprit.

  • After upgrading to Mountain Lion it's not possible to play videos in Fullscreen Mode

    Hello everyone,
    after upgrading to Mountain Lion on my iMac (27 inch, Mid 2011) I got the problem, that every video or movie in full-screen mode jiggles after a while. I'm using my Mac as a TV with Elgato EyeTV - and usualy I use it in full-screen mode.
    A complete new installation from scratch didn't solve my problem.
    If the problem occurs, the processor idles ans the hard-disk activity is low.
    Is there anybody out there, who can help me?
    Regards,
    Stephan

    If the issue only occurs when watching TV (using Elgato) then it's an issue on their side. Try a browser window and if can view the browser in full screen mode then that proves the point. You can also create another user account, log into that account and see if the issue is still there. If it disappears then you have an issue in your normal user account that needs to be tracked down. If the issue persists then your issue is global.

  • ITunes movie playback, audio and video not in sync after upgrade to Mountain Lion

    After upgrading to Mountain Lion I have problems with iTunes movie playback, and the audio/video at times stalls/delays, or skips a few seconds, or even gets out of sync.  I feared this problem was isolated to my machine until I saw an article online: http://reviews.cnet.com/8301-13727_7-57489874-263/sound-stuttering-after-mountai n-lion-installation/.  I have 2011 iMac 27" with 16G RAM and am running the latest iTunes and Mac OS X software, and shutting down extra programs doesn't help.  Please let me know of any solution.

    I also have this problem, and some videos will no longer play in iTunes.
    I get a message that this video is not compatible with this version of iTunes. I have to open the video in Quicktime to watch it.
    Unacceptable! This hardware and software is too expensive to have these performance issues.

  • TS1277 "iPhoto was unable to connect to Photo Stream" error after upgrading to mountain lion

    Has anyone gotten this error after upgrading to mountain lion on a computer that already had a user setup on it?
    My iphoto was working with photostream and now it will not connect at all.
    I ran fix disk permissions and once it showed up in iphoto, photostream was loading and then it disappeared again.
    help!

    FWIW I fixed mine when I realised I'd probably downloaded iPhoto using an AppleID from the App Store but logged into iCloud with a different AppleID. I deleted iPhoto and it's related files (but not the iPhoto Library) using CleanApp, entered the App Store with my usual AppleID and downloaded iPhoto again. Once the App Store, the downloaded iPhoto and iCloud logins were the same iPhoto Stream worked again.

  • ITunes doesn't sync iCal with iPhone after upgraded to Mountain Lion

    iTunes doesn't sync iCal with iPhone after upgraded to Mountain Lion. I even tried to use Replace Information On This iPhone and it doesn't work. Any idea guys?

    I'm having the same problem. It's as if my iPhone and MacBook Pro now have two separate calendars.
    Basically, I have a MacBook Pro (Mountain Lion, 13", late 2011) that I sync via USB with an iPhone 4S (iOS 5.1.1). Before upgrading to Mountain Lion, all of my iCal events would sync flawlessly. But none of the events I've created in iCal (Calendars) since upgrading have synced to the iPhone. Likewise, no new events that I create on the iPhone Calendar will sync to iCal. Also, changes to an existing event (even one created before upgrading to Mountain Lion) don't get synced either.
    Everything else seems to be syncing just fine though (music, apps, contacts, etc).

  • After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

    After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac.  Anybody having similar probelms?
    I am thinking about doing a clean install of Mountain Lion.  Would I be able to restore my applications and data from Time Machine after the re-install?

    My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem.  After it sleeps, I go to use something... and the beachball of death occurs.  This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
    It could possibly be revolving around safari... as that is really the only thing that is running consistently.  I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
    This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008.  This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
    I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?
