How can I programmatically tell apart a QTVR scene from a .mov video?

Hello
I am implementing a program that needs to tell apart whether a .mov file contains a video or a QTVR- seeing as QTVR can be stored with the .mov extension. As the .mov files are in binary format, is there a library, piece of software or any other way to use in my Python code to tell the two apart?

  • How can I programmatically remove a selection of plots from a waveform graph?

    I have a waveform graph to display a number of plots, which I need to programmatically add and delete to as selections of data are chosen by the user for display.
    I've looked under the VI Server Property node and cannot see anything suitable for adding extra plots, or removing existing plots. I expected to see a Plot Data array variable, with each element containing the data for each of the plots on the graph. There is such an array for the annotations, which I can easily edit by Removing Subset for Array, or Insert into Array, but nothing for the plot data. The Value property is a Variant, which I'm unsure how to handle. Should I be working with this perhaps? Can this be done by creating a Local Variable read node? Or am I missing something simple here??

    Hi Mike,
    I was trying to use the Property Node (Value) to read the waveform graph, but I was getting a Variant type back, not a 2D array of DBLs as I expected. Turns out I was passing the graph control reference to a subvi whose control refnum had the Include Type flag unchecked. As a result of this explicit definition, Value was of an uncertain (undefined) type and couldn't be natively provided. It would have had to have been cast into a more specific type to work. Have solved the problem by ensuring all my references are of a strict type, and now (as you recommend) the Property Node (Value) is useful
    Many thanks for the response!
    And many thanks for the demo too! You put that together remarkably quickly!

  • How can i/adobe tell which licence (student or normal) things are created in?

    How can i/adobe tell which licence (student or normal) things are created in?
    Basically i want to know how i can find out, (in an exported jpg for instance) where it would say it was created in the student edition or in the normal edition. I dont want to put files that would be going against the student licence (which for those of you who dont know you cant create items to sell in a student edition) on the internet to make money.
    I have put i/adobe because if no one can tell what files are created in, and i have the licence for the normal one then it should be okay.
    Hope some of you can help,

    Hi,
    Could you please let me know how can I programmatically clear a chart? I would like to run a code multiple times and everytime I run it , the chart should be cleared . I tried to find a History property node but seems like there is no such properfy node for chart

    If I have conceived your problem clearly, there is of course history data property node for charts. You may get one by right clicking on chart

  • How can I programmatically change a label?

    Hi everyone,
    I have a 2-D array that I wish to populate with different sorts of data.  Depending upon the data, the names of the rows and columns may change.  Arrays have to have identical labels and I suppose I could simply populate a string indicator, but frankly, that looks like trash.
    How can I programmatically change a label of a column or a row in a 2-D array?  Should I consider using a table?  I want it to look nice.
    Thanks,
    Jason

    Hi
    I do not think you are able to change the label programatically.
    But you might consider to use Captions instead of labels. You can hide labels and make captions visible programatically, and you can change the text of the caption and size (see enclosed vi).
    take care

  • How can I programmat​ically detect transition times in a digital waveform

    Hi, I have a digital waveform and at certain times I have transistions and glinches , how can I programmatically detect and record the time stamps of the transitions
    Thanks  

    Let me see if I understand you. You are reading 14 bits in parallel and you want to know how long between transitions of just one of those bits - say bit 11. Is this bit number constant or can the number of the bit in which you are interested change?
    Well, you could XOR the value from each read of the digital bits with the 14 bits you got from the previous read. If the resulting value of bit 11 is true, the state of bit 11 has changed. Use that flag to read/restart an interval timer. Of course the resolution of your measurement will be dependent upon the rate at which you are reading the 14 bit input. If you are only sampling the 14 bits every 500 msec, you obviously won't be able to measure intervals of less than 1/2 sec.

  • Iphone4 would not restore Error -50. I have tried to restore and it restored it to the point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out.

    Iphone would not restore---- Error -50. I have tried to restore, and it restored it to the new point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out. I can see earlier backups in my C:\Documents and Settings\user\Application Data\Apple Computer\MobileSync\Backup folder. There are four subfolders in this address. I need my contacts, photos, and messages back. I know this is a common error but I can not figure it out. I have ran the other troublshoot items in the error steps for 13 and 14 like apple says. Is there a way to call apple and get a step by step of how to restore from another restore point? Does anybody have a solution????

    It tells you to go to Error 13 and 14 if you receive error (-50).
    Here is what I have tried...
    Error 13 and 14: These errors are typically resolved by performing one or more of the steps listed below:
    Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting. I have moved it around to different ports.
    Put a USB 2.0 hub between the device and the computer. Didn't change anything.
    Try a different USB 30-pin dock-connector cable.
    Eliminate third-party security software conflicts. Removed all virus protection and firewall.
    There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.Used the Microsoft fix it.
    Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online. Doesn't matter.
    Try to restore from another known-good computer and network. I do not know how to do this or how to find the correct/full/complete restore point. There should be more information for this.

  • How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs

    How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac? Thanks a lot. Carlo Molinari (Rome - Italy)

    How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac?
    The following are the basic steps to transfer your iTunes Media folder from your MacBook Pro to the Time Capsule (TC). Note: You will leave the iTunes Library, and its associated files, on the MacBook Pro as you will only be moving the media files.
    Be sure to shutdown iTunes before starting.
    Next, move the "iTunes Music" folder, located in ~/Music/iTunes/, to wherever you want on your TC's internal hard drive. Remember to leave the Album Artwork folder, as well as the three individual library files where they are on the MacBook Pro.
    Wait a while. If you have a large library, this will take a bit of time.
    Once the iTunes Media folder has been transferred, open iTunes. Note: It will still be looking at your local iTunes Library on the MBP. As such it will think that the iTunes Media folder is still on the MBP as well. However, we just relocated it to the TC. If you attempt to select any song, you will get an error that the song is "missing." Not to worry, we will correct this in the next step.
    We need to tell iTunes the media has moved to the TC's internal HDD. To change where iTunes "looks" for the media, open iTunes and go to the Advanced > General tab and use the "Change..." button to tell it where your new "iTunes Music" library is located.
    Once this is done iTunes will likely pop up a progress window telling you that it's re-analyzing your library. Let it complete this step.
    As a final check to make sure everything when as planned, click on any library file from within iTunes and press cmd + i (or View > Get Info). At the bottom of the Summary tab in that window is a "Where:" section that tells you the actual file path to that piece of media; be sure that path begins with the name of your TC's drive, and not "Macintosh HD."

  • How can I get iTunes to display the tracks from a CD in their original (album) order?

    To be absolutely honest, I don't really understand what this box is for, so I shall just use it to repeat and expand on my question. (I have already sent a "Feedback" comment on the same topic).
    How can I get iTunes to display the tracks from a CD in their original (album) order?
    It seems to me that there is something very basic wrong with the way iTunes handles CD Tracks.
    Professionally produced CD tracks are seldom if ever in a randomised order. Why then does iTunes seem unable to display the tracks in the order they appear on the original CD source - whether from a personally owned CD or from a download from the iTunes Store?
    Some music demands a specific, non-alphabetic sequence in order to make sense. Why does it seem that iTunes only offers Alphabetic, or reverse alphabetic order - both of which make a nonsense of the original, often intended order of tracks?
    Why not replace the so-called "cover-art" in the bottom left hand corner if the iTunes window - which, while it may look attractive to some, gives the barest of information concerning the original disc, with a list of the original CD tracks in their original order, so that the user can easily reestablish the order in which they should be played.
    As I would expect legibility might be a problem with doing this, why could not the original contents, (in their original order), at least, be displayed when the "cover art" is double clicked-on - the result of which at present gives me an enlarged version of the "Cover Art". While on the subject of the contents of the source disc, what about all the album notes which someone takes trouble to write in order to increase the appreciation of the music on the CD and the listener's general background knowledge of the artists involved. Such notes, it seems to me, have considerable intrinsic value in their own account. I would, I think, normally be prepared to buy such "Sleeve notes" - so long as a "taster" was supplied (as it is for the music) - for something like the cost of a single 'Tune" on iTunes.
    These two aspects let Apple iTunes down enormously, in my opinion. I think that by chopping even quite protracted sequences of music up into bits does no one any favours - except perhaps Apple's already quite substantial bank balance. People have to be aware that two and a half, to three and a half minutes is a very short time to develop a piece of worthwhile music, and that there are many, many composers, not all of whom are alive today who have written music that huge masses of mankind value for the enrichment of their lives and the human condition in general.
    Please make the viewing of iTunes tracks in their correct order by default possible. By all means have the alphabetical variations available as offering a different approach to the music, but not the sole approach to it - PLEASE.
    Frustratedly yours
    Alan Whitaker
    PS I work at my old 24" iMac Intel Core 2 machine which runs OS "Tiger" - because it is more beautiful to look at, the screen is more pleasant to work on, and because, in some ways it is more capable (it will run FreeHand MX without needing a "patch"), than my more recent 21.5" which runs "Snow Leopard". (I don't find it that much slower, either).

    Dear Mike
    Thanks for the support. I am utterly amazed that after all the hype about how good iTunes is that it cannot play a downloaded CD in the correct order, and that what that order should be is not available directly from within one's own iTunes installation. (I know that one can go back to the iTunes Store to check what the order should be, but having downloaded the tracks surely iTunes is clever enough to retrieve this important information.
    My iTunes to differ from yours in that I have also noticed that it seems unable to download copies of my "talking books" in the correct order either. But in my case it downloads them - from a CD - in order, but with the first track downloaded first - so that it appears at the bottom of the column of tracks so that it would get played last! (At least this is, while being inexplicable, a relatively "logical" bit of blundering and because of this is relatively easy to put right!).
    I like many genres of music, some of which are not really programmed except perhaps by the artist performing them. I know that Frank Sinatra was very careful to programme his album songs to obtain a particular effect and in relation to the keys of the music. iTunes presumes to know better.
    Film scores may be totally randomly put together, in some cases, but in others the order is vital to one's appreciation of the music as a whole and how it relates to the plot of the film.
    In symphonic music most works are divided into sections and are conceived by the composer that way. Some individual sections may gain a life of their own if played separately, but they are never complete in the sense that the composer envisaged them without being placed in their proper context.
    Opera and probably most choral music too, is similar except that the words may well become meaningless if the order is changed at the whim of a piece of ill-written computer code, while ballet music has to be heard totally within its sequential context or it becomes meaningless.
    Finally, I would venture that iTunes, by jumbling up the order of the tracks as recorded on a CD, does an immense disservice, not only to the music on a particular CD, but to music in general, by expressing everything in terms of "Songs" - which it seems to interpret as stand-alone items of between 2 and 4 minutes whatever the genre. Even the way the iTunes publicity speaks of how many "songs" it can store instead of how many minutes or hours of recorded sound. This has to be another brick in the wall of "dumming-down" of people's expectations, and the shortening of their attention spans.
    I don't know about anyone else, but I feel betrayed by Apple over this. Perhaps the look, feel and general presentation of an item are not the most desirable features of a consumer product. Maybe it should be judged more on it fitness for the purpose for which it was sold. There is one other possibility - that Apple are trying to redefine "Music" - and that everything that lasts longer than about 3.5 minutes or is in the form of what could for want of a better term be called symphonic in the broadest sense is something else - not "Music" within Apple's new definition, at all!
    Well that's off my chest! now I can get down to creating some sort of order in my iTunes Libraries, knowing that I have to reconsult all the sources in order to confirm the source playing order.
    Anyway thanks again. At least I know that it is not just me

  • How can I connect my iMac to a TV for playback of videos? My TV does not have HDMI.

    How can I connect my iMac to a TV for playback of videos? My TV does not have HDMI.

    You need to find out what video out you have on your iMac, and what kind of video inputs there are on your TV.
    It will help to know exactly what model iMac and exactly what make/model TV you have.
    Depending on the exact model iMac you have, it may have miniVGA, miniDVI, miniDisplayPort or Thunderbolt output.  Your TV may have composite, S-video, component, DVI, VGA or HDMI inputs.  Once you confirm what kind of ports your iMac and TV have, then we can probably suggest the correct cable or adapter so you can connect them to each other.

    I have copied my CDs into iTunes  (currently running v11) to play on my iPod.  I have now bought a non Apple mp3 player to use when I am out running.  How can I copy the many tracks I want from iTunes onto the new player?
    Thanks

    I tried Notpod but can't get it to work.  Part of the problem, I suspect, is that I can't create a folder on my player (a SanDisk Clip+).  I also can't do this in Windows Explorer.  Whilst I can see the Clip+ in Explorer, the option to create a new folder isn't there.
    The error mesag I get in Notpod is:
    "Unhandled exception has occurred in your application.  If you click Continue, the application will ignore this error and attempt to continue.  If you click Quit the application will close immediately.
    InvalidArgument=Value of '0' is not valid for 'SelctedIndex'. Parameter name: SelectedIndex"
    Then, when I plug the Clip+ into a USB port, iTunes thinks it is my iPad - which is because, I guess, Notpod hasn't worked.
    I can drag and drop files from the Music folder where my iTunes tracks are stored onto the Clip+ and they get converted but I'd rather synchronise a Playlist from iTunes if I can.
    Thanks anyone who can help
