How can I use QuickTime SDK to get Compress format of Video stream?

I can get uncompress video stream like this:
QDerr = NewGWorldFromPtr( &m_hGWorld, k32BGRAPixelFormat, &rcMac,
NULL, NULL, 0, (char*)m_pVideoBuffer,
m_sAVFileInfo.sResInfo.ulWidth*4);
then the m_pVideoBuffer is uncompress video stream. How can I use QuickTime SDK to get Compress format of Video stream? I could change "k32BGRAPixelFormat" to other format,use other API or something?
Could someone have the method? Best Wishes!

Firefox, I would make sure you update your Desktop to Firefox 14.0.1, as the version you are running is quite old and out of date.
Then, do you have your Sync Recovery key, username and password? If you do, you can re-add Firefox Sync to your computer.

  • How can I use QuickTime to make a screen recording that has both video and audio?

    How do use QuickTime to make a screen recording that can be saved with both video and audio together?

    do you know of any software that would record a QT movie playing on my Mac screen with both audio and video?
    I have used Ambrosia's Snapz Pro X ($69) for years, but they are currently upgrading their Kext (Kernel Extension) software for changes inroduced by the Lion release so it might not be your best bet at this time. I also use ScreenFlow but it is a combination capture and editing utility which runs $99 and may include more features than you may need or will use. Have also tried Screenflick ($29) which, to some extent, appears to have a functionality somewhere between that of Snapz Pro X and ScreenFlow. It is a bit more complicated to set up but for the price might be the best bargin at this point. All three can capture the entire screen or a portion thereof, with or without mic/line and/or system audio. (Or at least they all will as soon as Ambrosia updates its Kext routine.)
    Here is a URL link posted by QTKirk three days ago to an article that recaps of a number of currently available third-party screen capture apps from around the world several of which may interest you: http://mac.appstorm.net/roundups/utilities-roundups/10-screen-recording-tools-fo r-mac/

  • Can PQA use a single reference frame against a test video stream?

    For R&D testing of video "set-top" devices I want to initiate some internal processing on our UUT, then using a PXI-1491 analyze the digital (HDMI) video output of the UUT for some large number of seconds (180 seconds or more for example).
    The video that is being analyzed will have static image content. The amount of time I want to analyze the test stream after doing some stuff on the UUT is variable, but I always anticipate it being fairly long.
    It currently appears that I have to have a reference stream that contains exactly the same number of frames as the test stream.
    This makes the reference vbf files very large. My test requirements include a large number of resolutions that must be tested through the UUT. Having an extensive library of very large vbf files is logistically difficult, it would much easier to maintain such a library made up of single "golden" frame reference files instead.  Additionally, since my analyze time needs to be variable depending on test setup and UUT processing options, it would be better for me to have a single golden reference frame and validate alot of test frames against it.
    Since the analyzed video will have static images, is it possible to run a test video stream against a single reference frame (reduced reference) instead of having a full reference stream frame by frame?
    Solved!
    Go to Solution.

    Doing exactly what you are asking is not within the design of PQA.  Of course, the best option that we would recommend when working with video test is a large capacity hard drive, probably in a RAID configuration for more space and better performance, and then just taking a golden reference with 10k frames, and doing what you originally suggested.  
    One method of achieving what you are looking for without using a large reference file is through offline processing.  This would allow you to acquire 10,000 consecutive frames, which I understand is one of your concerns, and then after the fact run them back through the analyzer.  You would still be performing a looping type of action in TestStand or LabVIEW.  The process would be:
    1) Acquire your source from your 1491 provider with no processors, and saving the media stream to disk.
    Loop:
    2) Load PQA with the disk buffer provider instead of the 1491, the disk buffer file will be the acquisition from above
    3) Point the start frame to your current location.
    4) Perform your processor with the results.
    5) Repeat and iterate to a new start frame location
    This process is going to be much slower as you load and unload resources every time.  If you choose to go this way, a better implementation would be to maybe consider doing 100 frames at a time, or some number larger than 1, because the processing time of handling the extra frames is going to be less than loading/unloading PQA.
    Your second option is going to require more work outside of PQA to implement custom functionality through a Custom User Processor.  Effectively this allows you to come up with a way to process incoming data in ways that you'd like.  To do this you will need:
    1) LabVIEW 2011 - Custom User Processors for PQA can only be developed in LabVIEW 2011.  If you are under a SSP agreement with NI and only have LabVIEW 2012 currently, you still have access to older versions.
    2) Vision Development Module - To perform your image processing
    3) An unencrypted video source - Due to limitations of HDCP we can not expose the raw video feed to user processors.
    In this user processor you would:
    1) Load your static image/frame in directly, you wouldn't need to use the Media Ref input
    Loop
    2) Load the current frame from the incoming video array
    3) Perform your video measurement with the Vision function, likely PNSR or SSIM since these are currently the only 2 referenced measurements in PQA.

    I've heard of puffin browser but that only works to VIEW flash content. I wanted to chat online in a webpage called www.chatroulette.com, it's really awesome for meeting new people so wanted to give it a try. The customer service line and the technical assistance line are not able to help me at all. There has to be a way to enable idevices to utilize flash. C'mon apple, don't be so strict.

    I am aware of Google number for my iphone.
    However,  I want to be able to phone my laptop.
    Basically,  making my laptop a phone.
    Can this be done and if so, how?

  • How can i use apple tv and iTunes movies with component video cables for an older receiver and projector?

    i have an older yamaha receiver and projector both without hdmi inputs but component video instead. I would like to get apple tv and start renting movies through iTunes but apple tv only supports hdmi and ive read that iTunes has codes to prevent the use ot analog cables with movies. Is there a way to adapt hdmi to component video for both apple tv and iTunes easily?

    Yes, HDMI is the only supported method. Also, with converters you will run into issues with HDCP (which will prevent you from streaming DRM content from iTunes etc) as well as resolution.

  • How can I use the "Copy and paste" tool in order get stamps in the same position in different pages (Acrobat XI for PC)?

    With Acrobat 6.0 I was able to copy a stamp in the same position (I mean "exactly" the same one) of different pages just by using the "copy/past" tool.
    Now I am using Acrobat XI and it seems like it is not possible anymore: I am copying a stamp and I am trying to past it in anoter page, but it appears in the center of the page (or wherever it wants to...).
    Does anyone have a solution?
    Thanks in advance.

    Thank you very much. I'll be waiting for you message.

    I will address your second question.
    First, make sure your iPhone and iPad have absolutely identical Apple IDs.  If they do, use that Apple ID in Settings > iCloud on your iPhone to select the "Notes" option.  Lo and behold, all your iCloud notes should appear on your iPhone.

  • I was trying to get the iOS 8.2 on my iPhone 5 but then it stopped and my phone is now on recovery mode I have pictures I need and they did not all fit on iCloud  how can I use the phone again with ALL my pictures and videos without restoring it?

    I was trying to get the iOS 8.2 on my iPhone 5 but then it stopped and my phone is now on recovery mode I have pictures I need and they did not all fit on iCloud  how can I use the phone again with ALL my pictures and videos without restoring it?

    Contacts are designed to be synced to a supported application on the computer or a cloud service.
    Pictures taken with the device are designed to regularly be copied off the device to a computer as would be done with any digital camera.
    If you have failed to use the device as designed it may be too late to recovery anything.
    Is the device regularly backed up to a computer via iTunes?  If so, the most recent backup (when restored to a replacement iOS device) should contain all contacts and pictures as of when the backup was created.

  • How can I use Iphone 4 as an mp3 player without a sim card until I get one?

    Hi,
    How can I use Iphone 4 as an mp3 player without a sim card until I get one? I just bought the phone and each time I try to switch it on to use the mp3 player, I cannot. It asks me to insert a sim card and I don't have a sim card yet. I was thinking I could use the mp3 player function of my phone until I buy a sim card.
    Thank you for your help in advance,

    Thank you, I understand, yeah, I knew that, my phone is factory unlocked and I am going home, which is obviously not in the States and I am thinking of buying a local carrier there. However, I still have 2 weeks before I leave and cannnot wait to start using my Iphone 4. I thought at least I could use the mp3 player function. So as far as I understand, I cannot activate it without a sim card. I have been using metropcs for about two years and it does not have a sim card. In this case, do I really not have another choice but wait for two weeks to listen to music? My Mp3 player just failed me and I really need to listen to music but on the other hand, while I can use my iphone as an mp3 player in two weeks, I don't want to spend more money on a new one. So, do you have another suggestion? For instance, can I use a friend's sim card to activate mine? Would this cause any trouble, when I go home and buy a local carrier? I think these questions might kinda sound weird to you, but first time with an Iphone, extremely excited to start using under my circumstances, I need help   thanks,

  • HT4145 How can I use an Airport Extreme to act as a Range Extender for an Alcatel One Touch Y800Z WiFi modem/router? I get a message saying it cannot be extended. Thank you. Arup

    How can I use an Airport Extreme to act as a Range Extender for an Alcatel One Touch Y800Z WiFi modem/router? As we live in a rural area and our landline broadband speeds are awful, I have moved on to a 3G provider in the UK (EE/Orange) and set up the wireless modem which is working very well with an iMac. I have an Airport Extreme base station which was previously connected with an Ethernet cable to the landline router, and two Airport Express stations as Range Extenders. I would now like to use the Airport Extreme and the two Express stations to extend the range of the Alcatel WiFi device. I have tried automatic and manual set up with the Airport Utility but at the crucial step for selecting a network to extend, although the WiFi device is recognised, I get a message saying it cannot be extended.
    Thank you for any help you can provide.
    Arup

    This is a problem with a lot of cheap end wifi hotspot like devices.. sometimes you can just swap the sim out to a real 3G wireless router.. that is a better approach IMHO than wireless repeater ever will be.
    In the meantime..
    Have a go with the suggestion.. place the express as wireless bridge. With a computer connected to the wifi from alcatel unit.. (I am amazed Alcatel still are in domestic market.. I thought they sold out). Set the express to join the wifi.. you do this in the airport utility.. old one is easy.. but in v6 you have to trust to luck so to speak and hope the auto setup works.. tell us if you have trouble.
    With the Express bridging.. you can then plug it by ethernet into the TC.. which will be in router bridge..
    ie
    You can then run the connection from wireless or ethernet on the TC.. and it will relay back to the alcatel for internet.. all a bit dodgy but who knows.. it may give you what you need.
    Wireless repeater is never particularly reliable in my experience. I would avoid it if possible.
