IPhoto Played Video But Hung 100% CPU + AVF error: branch_QT0, getCmdListAsync

Any ideas on what
iPhoto: AVF error: branch_QT0, getCmdListAsync
Means and what may be causing it?
Thanks.
Imran

Same thing happened today....
Playing a different 30 second iPhone video in iPhoto, stopped it, double clicked it and it took iPhoto to 100% CPU (one core or distributed on four but still totaling around 100%) and Console shows one instance of:
7/24/12 2:37:29.386 PM iPhoto: AVF error: branch_QT0, getCmdListAsync
Activity Monitor reports 1 recent hang (this one probably) and no other Faults.
Wonder if anyone has a clue what this error is about. Seems to be QuickTime related, from the QT reference, but that is a guess on my part.

    firefox plays video, but no sound. when I type about:plugins in location bar, it shows the firefox default plugin is not enabled. When I look at my plugins, it says it is enabled. I have uninstalled 3.6 and re-installed with the same result. Why do I have no sound. Computer plays I-tunes and all other sounds, just no web browser sounds.

    Glad you seem to have sorted things out.
    The warning about the warranty is light hearted, I think at one stage it warned "here be dragons" but also intended to make us think as it warns that making changes may produce problems.

  • I tunes won't play a song on my Windows 8 computer.   Plays videos but won't play music.

    Itunes will not play music on my HP laptop.  I have uninstalle and reinstalled but no success.  Plays videos but not music.

    Almost certainly a damaged track, then.
    Delete the current copy of the track from your iTunes library, and reimport a fresh copy from the CD. Does that one play properly?

  • Elements Organizer 8 - some WMV are not displayed properly in the Play Video but are in Play Vide

    Hello:
    Elements Organizer - some WMV are not displayed properly in the Play Video but are in Play Vide on Full screen. What's the problem? Wrong codec?

    Because WMV's can contain a lot of flags, like DRM, they can exhibit odd behavior, indeed.
    Usually, AV files will display in their native resolution, i.e. in their set Frame Size/Aspect Ratio and with their set PAR (Pixel Aspect Ratio), but sometimes those flags are missed, or are altered by other programs.
    Remember, WMV's are designed to be streaming delivery-only, and are not intended, or designed to be edited. Most NLE's (Non Linear Editors) will allow them to be edited, but will require extra processing to do so. As is mentioned, WMM is designed around editing that delivery-only format, but most others are not.
    There are many other formats/CODEC's, that ARE designed to be edited by the vast majority of NLE's, such as DV-AVI Type II's.
    The best workflow is to NOT bring WMV's into the mix, unless one is using WMM exclusively. Converting those to an easily editable format/CODEC will always be the best course of action.
    Good luck,

  • MY I POD PLAYS VIDEOS BUT THERE ISNT ANY SOUND aNY IDEAS ON HOW TO FIX?

    HOW DO YOU GET SOUND TO PLAY ON VIDEO CLIPS?

    Quicktime, Quicktime Pro and iTunes don't convert "muxed" ( muxed means multiplexed where the audio and video are stored on the same track) video files properly. It only plays the video and not the audio.
    See:iPod plays video but not audio.
    You need a 3rd party converter to convert the file with both audio and video.
    Videora is one, and there are others.
    http://www.videora.com/en-us/Converter/
    Search the iPod video forum for other recommendations, but beware of spammers trying to sell you their own product.
    And may we ask you to turn off your caps lock? It's considered shouting.

  • My new ipod nano plays videos but there is no sound, why?

    My new iPod nano that plays videos has no sound going along with them. It's not a problem with the iPod, (I don't think) because the sound won't play on iTunes either, yet my music in playing just fine both on my ipod nano and in itunes. I dragged and dropped the video into itunes then I converted the video then used the convert selection for ipod. Why is there no sound? Is there something I am doing wrong? My 30gb ipod did worked just fine when I did it that way but my new ipod nano won't. Is there something else I have to do before I can watch and listen to videos?
    Any help would be greatly appreciated.
    Thanks!
    Becca

    QuickTime expects video files with separate video and audio tracks, but many MPEG formats used a muxed (multiplexed) single track that contains both. Therefore, iTunes & the iPod (both of which use QuickTime) only show the video and no sound.
    iPod plays video but not audio of some exported files

    One way to work around this is to use MPEG Streamclip to convert the files to fix this issue...

  • QT + MPEG-2 plays video but no audio

    I'm trying to play mpeg-2 videos that were created by my video camera. I've got QT 10.0 running on OS X 10.6.4. I found QT didn't recognize .mpg, so I purchased the mpeg-2 playback component. With it installed, I can now view my .mpg videos but they have no sound. What am I doing wrong?
    I'm a apple rookie, be gentle

    Just to document what I've found so far. I tried installing QT 7, the MPEG-2 addition from apple again. It would still play video but no audio. Unfortunately, the test mpeg-2 from apple support DID work, which indicated I must have something wrong with my file. However, this is one of 250+ files I have recorded from my digital camcorder and they play on any number of Windows players without issue.
    I then tried Perian codecs since I found references it would address a similar problem. I tried VCD and MPEG Tools from BurningThumb. I tried mpeg screenclip. I also tried changing my Audio Midi setup to 2ch-16 bit from 2ch-24 bit. All to no avail.
    In the process I found that my .mpg files and .avi files had the same problem. Both played video fine but neither had audio. I then installed VLC and presto! All worked as they were supposed to!
    I still don't know why QT won't play it--it seems like it should.

  • Video files use 100% CPU

    I purchased and completely downloaded a few video files from iTunes. I do not have an iPod video, but was going to view them on my PC. When I play the completely downloaded files, the video is really jerky and my CPU usage is at 100%. The computer is an IBM Thinkpad 1.8GHz celeron with 512 MB RAM. This should be plenty fast to play video files. The videos are so bad they are unwatchable. Since I downloaded them to my laptop and they have DRM, I cannot transfer these files to another computer to play them. What is the point of being legal and paying for videos when I can't even use them.
    I have uninstalled iTunes and Quicktime and then just installed Quicktime to play the files and CPU is still at 100% and video is still really jerky. I have no other programs running in the background and have shut down any unnecessary process, but still the video is unwatchable. If anyone has any ways to fix this, please let me know.

    I can imagine a lot of things, none of them are useful.
    I verified the disk and the protections. I had to boot into safe mode or whatever it is called in order to perform the repairs. No change ...
    I have now also got a problem with the imklaunchagent which is sapping 100% of 1 CPU. This is some input framework for asian languages or some such useless rubbish. I have posted here about this as well. I am not alone apparently.
    This Mavericks upgrade is proving very costly, my time is not free!

  • 10.5.2 iTunes on Windows 7 x64 bit laptop - Quick Time will play videos but not iTunes

    I'm hoping you can help, I've looked for a solution to this for a while now.
    I store my itunes library on an external hard drive. I completed a clean install of x64 bit Windows 7 on my laptop - all went perfectly. Downloaded and installed the 64 bit version of 10.5.2 iTunes and located my library...the music plays fine but no videos. I opened iTunes in safe mode and it said that I needed the up to date version of Quick Time. Downloaded and installed that...no problems. Now my vidoes will play in the Quick Player but still not in iTunes! They apprear in the "Now Playing" pane but the timer doesn't move - even after pressing pause and play. Can anyone help me please? Do I need to open iTunes in 32 bit mode? If so, how do I do that in Windows 7? i can only find solutions for Mac's....
    Thanks in advance

    I should have posted this earlier, but anyway. I restored my laptop to factory version after backing up any useful data, and the first thing I the laptop was restored was connect to the internet, download and install the latest version of iTunes. And Bingo! It worked.

  • Quicktime plays video but no audio

    Trying to play Quicktime videos from Prentice Hall website associated with textbook. Browser has up-to-date Quicktime plug-in and when tested there is video and audio. But when video is played from selected website, there is video but no audio. Tested using Google Chrome, Internet Explorer and Mozilla Firefox but results are the same.

    Jacumba,
    Here is the link that the professor provided -
    http://wps.prenhall.com/chet_martin_audiology_11/194/49692/12721280.cw/index.htm l
    The instructor tried on the computer in the classroom that she uses and I also tried it on the computer in my office. ON that website are different QuickTIme videos embedded in the different chapters. Clicking on the QuickTime link (box), the QuickTime logo appears, then the image appears but when Play is pressed, the video plays but there's no evidence of audio. The volume control on the QuickTime movie is at maximum and I have the volume on my computer at maximum, but there's no sound whatsoever. LIke I said, I have the latest QuickTime plug-in and when I test the plug-in, I get video and audio.
    I'm trying to find out an answer for the professor because she uses the website in her course.
    Any suggestions would be most welsom.

  • Playing Video but no Audio?

    I have all three Divx, Xvid and 3vix installed. Fist I couldnt see any vide, then I installed 3vix. The video is playing now but there is no audio.
    Anybody help.

    You probably need an ac3 audio encoder. .AVI's are sometimes packaged with this audio codec. It's free here

  • My ipod plays video but with no sounds....

    i uploaded some videos to my ipod, and they play fine, but the only thing is that i get no sound coming out of my headphones, its really frustrating....

    Welcome to Apple Discussions!
    This is because the video you converted was muxed. See this for more info...
    http://docs.info.apple.com/article.html?artnum=302588
    You would have to use a converter that supports muxed videos such as:

  • Satellite L850D WMP and VLC player don't play video but audio

    Hi,
    I have an L850D running win 7 and suddenly windows media player, VLC does not play video file but plays the audio file.
    When using youtube video plays.
    Does anyone have any ideas??

    What files are exactly affected?
    Did the video files work properly in the past?
    If not then I think you have got this issue because of missing codec.
    If the files worked properly in the past, then the issue may occur because you have installed or removed some codec from the system.
    Maybe you should check if you can go back to restore point where they all worked fine.

  • My 60GB Ipod used to play videos but no it doesn't??? help!!!!!

    Hi, there
    my ipod used to play videos, i then didnt play one for a while and it now doesnt play them anymore..... it doesnt seem to update them onto my ipod....thanks

    ok now are the videos that are not updating to the ipod the same videos that used to update to it? Or is it new content you have imported to itunes since you last updated the ipod with videos? Also, are these videos itunes purchased or user created content?
    See these articles for information on file formats that will play in itunes and import to the ipod (note: itunes plays more file types than the ipod will load, so just because a video will play in itunes does not mean the file type will update to ipod)

    Now once you have made sure that your videos are in the correct format and have been converted to play on the ipod, make sure that your ipod preferences are set to automatically update the videos. Or you can try manual mode and drag and drop em onto the ipod.
