NI Vision Video compression on-the-fly

Any ideas how to compress Video stream on-the-fly to 3-4 compressed video streams (high-quality, low, web...), built-in NI Vision filters are not good enough. FFDSHOW is not labview friendly, Quick-time is alright but requires complete AVI or go through saving individual frames to disk...
Do I need to create a labview-friendly encoder/decoder? (partially complete)
Any input on how to port it to windows enviroment?

P.S. CPU platform PXI-8133 with SSD drives - shouldn't be a limiting factor

You can start by calling an DLL from labview and passing an image to it, good links are here and here, but you should find more. You don't need to install OpenCV, just make a project, create a DLL, pass an image and call some IMAQ function inside that DLL. I guess you are weak in C/C++, there is some learning involved in the correct linker settings and proper includes so such simple example should get you started.
The next step is to pick an opensource codec, create a LabVIEW wrapper for the functionality you need, here is an example, how to manipulate objects in labview.

  • HD video compressed for the web

    I was doing some testing trying to figure out the best way to compress the HD video I get from the Sony XDCAM HD for the web (streaming). I shoot in HD (1080/30P) because it's needed for our videos. The web streaming is secondary.
    I would prefer to make the web videos .flv because it works best and most easily cross-platform. In the real world, the majority of users have Windows PCs, which made me hesitant to use h.264 (.m4v) because it probably would require the average user to download things they may not wan to. Nonetheless, it has to be viewable on all computers in all browers.
    So, I took three 10 second clips of steady camera video with audio from the camera that I used in all tests. I will refer to them by clip number...
    Clip 1: 30P 16:9 High quality, 10sec=45mb
    Clip 2: 30P 16:9 Low Quality, 10sec=24mb
    Clip 3: 60i 16:9 High Quality, 10sec=45mb
    First I tested making FLV is Adobe CS3 Encoder using the High Quality (700) setting.
    Test 1 used size 848x480 (16:9)
    Clip 1: 1.3mb
    Clip 2: 1.1mb
    Clip 3: 1.2mb
    Comments: Looked very crisp, audio was clean, slightly darker image than original on default settings
    Test 2 used size 480x270 (16:9)
    Clip 1: 1.2mb
    Clip 2: 1.1mb
    Clip 3: 1.1mb
    Comments: Looked very crisp, audio was clean, slightly darker image than original on default settings
    Next, I tested making .m4v using the h.264 iPod settings in Compressor.
    Test 1 used size 640x370.
    Clip 1: 240kb
    Clip 2: 1440kb
    Clip 3: 204kb
    Comments: Image wasn't quite as clean as the Flash files, but still good. Much lighter/brighter than the Flash files also. Low Quality HD video had high file size... why? I don't know, but I don't shoot on LQ for things anyway.
    Test 2 used size 320x180.
    Clip 1: 160kb
    Clip 2: 865kb
    Clip 3: 865kb
    Comments: Image wasn't quite as clean as the Flash files, but still good. Much lighter/brighter than the Flash files also. Low Quality HD video had high file size... also the 60i file...why? I don't know.
    In conclusion, I'm lucky that I shoot 30P since it worked well in all areas. The h264 codec provides a much smaller file size than Flash, with a good image. Amazing considering we started with a 45MB clip. What are the standards for aspect ratios for putting 16:9 video on the web? I haven't heard much set in stone like you have for 4:3 video. Nonetheless, the 640x360 or 480x270 seem to be a nice size for most uses.
    I have heard that in Flash 9 you can chance the m4v extension to flv and it will work. IF that is true, that would be great because now my concern is that a base Windows PC cannot play these .m4v images without plugins/codecs. I suppose right now its a tradeoff between smaller file size/less compatibility with h264 or larger file size, great compatibility with Flash.
    Any comments or suggestions to help out would be great. I typed this fast so forgive me if I left out any important info.

    Hi APPLE27:
    One comment from your post that immediately caught my attention was this, "Nonetheless, it has to be viewable on all computers in all browsers."
    Unfortunately, it is unrealistic to expect one digital video file to be viewable on "all computers in all browsers" as there are simply too may variations in both hardware and software.
    A common approach when offering digital video is to provide two formats to choose from and then within each of those two formats a few versions of the video for different bandwidths.
    For example, a web site might offer Video for Windows and QuickTime. For each of these, there would be a low bandwidth Video for Windows file and QuickTime file and a high bandwidth Video for Windows file and QuickTime file (four files total). Of course, there's also Flash Video, Real Video, MPEG1, and so on.
    For better or worse, YouTube.com has allowed video content creators the realistic expectation of creating a digital video file that is viewable on "most computers". But, the video is unavoidably tied to that web site.
    When it comes to online distribution of video, it's still very open ended.
    Also, computers are not all that's out there. Mobile devices are a huge market and you'd be hard pressed to create a single digital video file that will play on all mobile devices (iPhone, iPod Touch, Palm Treo, Sony PSP, etc.) either from local storage or from a mobile browser.
    QuickTime offers a solution for creating a referencing movie - one file that links to other digital video files, but it too is imperfect at best when it comes to reaching the broadest audience possible.
    With my few comments here, I'm just scratching the surface. But, it all starts where you are right now: caring about the image quality when exporting from your edited master.

    I am trying to figure out best strategy to MOVE schema from warehouse to different database (11g) in compressed format on the fly... don't want to export first then compress and move files which is older way...
    basically data should always be compressed during expdp n impdp...
    so far I can think of below....
    1. Lock user on warehouse
    2. Expdp user with expdp parameter compress=all
    3. Import user
    4. drop user from warehouse
    I think it's as simple as this but...
    Just wondering am I missing any key element for compress part?
    Do we need special oracle license to use compress option?
    any other tips or steps??

    Or as some might suggest, use network link and be done with it.

  • Change video format on the fly in JMF

    Hi!
    I am using some suns examples for transfering video/audio rtp streams over network to another computer which recives the stream with jmstudio.
    My problem is, that if i want to change the format (for example video-jpeg to video-H263) i have to close the processor, set everything like datasource...like on the begining and send the data. If i try to do this format change on the fly, and if i use my code, a new stream will be created, and a new jmstudio-window opens. But i want to change just the format without seting new stream and let it play in only one player-window.
    Is there eny posibility to solve this problem, mayby some code examples on internet (i tryed google, this and other forum...)?
    thanks for help.
    Adam

    Thanks. This should solve my player problem.
    But how to change a format without closing the processor and without reconnect end configure everything from beginning?
    Is there a possibility to change the encoding format on the fly (dynamically)?
    Bye Adam

  • Best Video Compression for the web???

    I have read a number of discussions about which codec to use to compress video for the web and I’ve done my own tests and bar the longer encode time, which is not a problem to me, H.264 seems to come out as the best. I can get a superb quality, small enough for a quick download EXCEPT… this website needs to be friendly to the PC community.
    What do you all suggest I do?
    Go with lower quality MPEG-4 or Sorenson 3 and have my work look “not so good” or use awesome H.264 and provide a link to download the codec, which busy PC people will probably not bother to do.
    This is my dilemma.
    Thanks in advance for any advice.

    I love the results I get when using H.264. Even low data rate files look good (even when I display them double size).
    But it requires your page visitors have QuickTime 7 installed to view your QT files.
    QuickTime 7 is nearly a year old and most of your Mac viewers will have it installed. It is also "bundled" with the iTunes software download that many PC users have installed.
    H.264 is the only codec that requires version 7. Any other choice can be played using older versions of QuickTime.
    As much as I like H.264 its installed viewer base doesn't reflect the visitors system settings for Web work. If your crowd is savvy to QuickTime they will not mind the download to upgrade. If you use tracking software on your visitors you'll be able to see if they hang around for the download.
    MPEG-4 may be a better Web use choice.

  • Adjust video playback brightness on-the-fly...?

    I've just moved over from a 5G iPod to an iPhone, and had a question about a certain aspect of video playback...
    I watch a lot of video on my iPod (now iPhone), and I'm a stickler for saving my battery life, so I always turn the screen brightness right down to its lowest viewable point when watching video.
    I also watch video in bed, with the lights off, so turning the brightness right down still makes the videos perfectly viewable.
    Sometime though, of course, I have to turn the brightness up for scenarios where I'm in a brighter environment.
    The way to do this on the 5G iPod is, at any time when watching a video, hit the centre button twice (once takes you to the scrubber) and then scroll left or right for dimmer or brighter. Easy. Job done. And you can see the results right there and then, so you can adjust it to just right.
    Now unless I'm mistaken, there's no similar way of doing this on the iPhone, and that you can NOT adjust video brightness on the fly...
    The only way to adjust brightness is, while watching a video, to go to Home > Settings > Brightness > Drag it > Home > iPod > Video.
    Surely everyone can see that's a MUCH more laborious way of doing things!?
    Even then, you can't be sure you got the brightness setting adjusted correctly, because a bright vivid animation, like The Simpsons, is much more visible and clear on a low brightness setting than, say, TV shows of Magnum P.I. with their 80's "converted-from-video" feel.
    And believe me, I know, because those 2 examples are real-world scenarios for me.
    And before anyone says it, yes I DO know about the "Auto-Brightness" setting, but I've tried it, and 9 times out of 10 it's too dim for my liking in a brightly-lit room (especially on the Magnum P.I.'s) and it's too bright in bed with the lights off (especially on the Simpsons)!
    So I suppose if I'm making this post a question, it would be:
    Is there no method of changing video playback brightness on-the-fly, while the video is still playing on-screen?

    Brett,
    You've been around on these forums long enough to understand what is and isn't allowed by the TOA, so I'm fairly sure you know (I don't know but could make a guess as well).
    In general this whole thread could be deleted... except that you asked a question at the very end of your first post (which was answered). That's all these forums are for, asking and getting questions answered. Editorial comments, rants and raves are not what we are here for.

  • Recording a stream and using it on the fly

    Hi,
    I'm trying to upload a video stream from a flash client and
    convert the video stream on the fly (from an external converter
    like ffmpeg or vlc).
    Since I don't manage to send the stream directly to the
    converter, a solution I have found is to publish the sream as
    "record", and have a converter read the file to perform the
    operation.
    However, when setting the record method for publishing, the
    recorded file is not written continuously. Incoming stream is
    buffered, written, buffered, written and so on. So, the program
    reading the file stops it reaches the end.
    Is there a way in FMS2 to either:
    - forward incoming RTMP stream to a stream converter (using
    an outgoing RTSP stream or something like that) ?
    - force FMS2 to dump the stream continuously, as soon as it
    receives the incoming data ?
    Thanks for any help,
    Greg

    Stream.syncWrite
    Availability Flash Media Server 2.
    Usage myStream.syncWrite
    Description
    Property; a Boolean value that controls when a stream writes
    the contents of the buffer to a
    FLV file when the stream is recording. When syncWrite is
    true, all the messages that pass
    through the stream are flushed to the FLV file immediately.
    It is highly recommended that
    user should only set syncWrite to true in a stream that
    contains only data. Synchronization
    problems might occur when syncWrite is set to true in a
    stream that contains data and
    audio, video, or both.
    ... sounds like a problem is occuring :)

  • Video compression on Zen Neeo

    Hello all!
    I was bought a Zen Neeon 2 GB from Japan as a gift recently. I'm quite fond of it so far, no problems getting music on and off or with the radio and getting videos on and off and converting them is fine too.
    BUT (yes, there's always a but) the video compression on the video converter software isn't up to much. An AVI of an hour long, full size, decent quality episode of spooks for example, runs through the converter software and whilst the picture obviously shrinks, the file doubles in size to about 900 mb, leaving no space for anything else! Does anyone know of a way to compress the files in the right format? I have tried loking for firmware / software updates but it seems the player has only been released in japan and I can't use that bit of the creative site!
    Any ideas? How can I compress files for this player?

    Hi! I also encountered the same problem [size="6" color="#ff0000">I wish I bought ipod instead of this JUNK!

  • Can Access DRM encryption be applied on the fly?

    Hi,
    ... and thanks in advance for responding. I have the following questions:
    Can Access DRM-Core and Access DRM-Pro encryption be applied to a video file "on the fly" for RTMP?  (I'm not interested here in Access Protected Streaming)
    How about for HDS?
    How about for HLS?
    By "on the fly", I mean at the time the request was made from the client and as a prelude to the  response from the media server. This would allow us to avoid creating and storing an Access encrypted representation of the video in advance.
    Thanks!

    There are a couple ways to generate just the "DRM Headers" without having to encrypt the whole file.
    1. If you're an Adobe Broadcast Licensee, with access to our Broadcast SDK (HDKb), there are APIs in there to just generate the DRM Metadata.
    2. If you have a recent version of AMS, the f4fpackager tool that comes with the product has had a recent revision where you can update an existing F4M (manifest) file to include a new DRM Metadata, which is created on the fly.  I'm not sure if this new f4fpackager tool has been released yet in the latest AMS, however.
    Besides those routes, the only other way to create a DRM Metadata would be to package an entire video.
    cheers,
    /Eric.

  • I am having problems exporting my time lapses from quick time pro i need to save my files as photo jpegs but the standard video compression window will not open fully,

    i am having problems exporting my time lapses from quick time pro i need to save my files as photo jpegs but the standard video compression window will not open fully, it just keeps my mac (old 1.6Ghz 2.5 GB sdram G5 still good for most stuff i need) spinning for ever but i can see compression type H.264 selected and the other setting but i can not select any other options as it still thinking but never opens! why is this happening how do i get round it?
    my work flow is: 300 images shot on a 5d mark II medium jpegs opened in Light Room cropped to 16:9 then exported and opened in quick time i can save a .mov H264 giving me files sizes of 14 mb for a 16 second time lapse, mp4 9 mb. the only way i can get large files is saving as a self contained movie then i get 300mb files.
    i need to save my files 1920 x 1080 photo jpeg codec as i want HD quality.
    i am sure there is a simple way round this?
    thanks guys!

    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.

  • Premiere CS5 will not render video with titles on the fly in preview window

    I am trying to use CS5 and notice if I add a title to the timeline overlapping any video and then attempt to play the video as soon as it hits the part with the title the video stops playing in the preview window. The background sound keeps going but video play back stops. In premiere CS4 it would render titles on the fly no problem. Why wont it do it in CS5? I should not have to render the timeline it should do at least a rough realtime playback without a full render. In CS4 it would play any and all effects on the fly depending on the resolution and the performence would vary depending on how many and what effects and transitions were applied to the clips but its very useful to get a quick idea how it will look. If I scrub, the titles playback while scrubbing no problem its only with actual playback it happens. Other effects and transitions I apply seem to render on the fly and play back in the preview window ok, it only seems to be the titles having the issues.
    Any ideas?

    Version = 5.0
    Language = english
    Latest updates = applied
    Issue happens regardless of sequence settings
    Windows 7 64 bit

    3 hard drives,  drive 1 = 1TB with 747gb free, drive 2= 1TB with 750 gb free, drive 3 = 200gb drive with 75 gig free
    Usualy capture video from a canon HV30 using Cineform Neoscene capture software, this is 1440x1080 HD 24p clips. (issue with the titles happens on any imported video in any format though, even with no clips but on a matt background)
    Cineform Neoscene capture software version 5 latest version
    Only using stock premiere plugins
    No error message
    I want to use the built in premiere title function to place titles along with fades and what not and then play back clips in the preview windows with the titles applied rendering on the fly. This works perfectly in CS4, just not in CS5. When I try it in CS5 after you hit the play button it will play the clip but as soon as you get to the part of the clip where the title is the video playback will freeze, mind you the clip is still playing in the sense that audio is still going just the video playback stops in the preview window. As a note if you scrub the video on the timeline the video clips will display with the titles applied it should, it is only when you hit the play button the problem happens.
    I have tried adjusing the quality settings in the preview window, updated my gfx card drivers and system drivers along with directx. Premiere is updated. I have tested other effects and transitions and they display fine, including super imposures such as chroma key or ultra key. I have adjust playback settings not that there was much to adjust there.
    I will say again in CS4 never had this issue, I am surprised to see it here.
    Please any ideas would be appriciated thx.

  • Resizing pixel art video without affecting the pixels with blur.

    Hello everyone,
    First I would like to mention that I did searched for an answer to my issue on the forum but only found a thread by Rowby Goren from Jan 4, 2010, who asked a similar pixel resize question regarding to still images in CS4. He was answered to use Photoshop for this kind of task. My issue on the other hand is for handling a video that can only be edited in Premiere. I'm using CS6. My issue is as follows:
    I work a lot with pixel art animation in 320x240 resolution. Usually I'm making a 320x240 scene of background and characters and the final result should be a doubled sized. So each pixel is actually 2 times larger. Just like old adventure games from the good old days that most of us remember. It works great with old style games creation engines however when I want to make a video with my pixel art creation in Premiere, I couldn't achieve an exact and clean doubled pixel when resizing the source by 200%. It always gets blurry. Does anyone knows if Premiere has any switch off option for scalling blur?
    I have created an image that describes the issue. It's just a simple pixel art image that I picked up on google search. I saved and uploaded it as PNG for best quality, I just hope it won't get compressed after the upload. Any assitance will be appreciated!
    Thanks,
    Gal Shemesh

    Thanks Jim, I am aware of the fact that it's a degraded image that doesn't have any antializing effect on it. And that's what I'm trying to achieve in Premiere, although it's currently impossible. Until now I'm doing exactly what you suggested, which is to double the size in Photoshop or other tool that doesn't affect any antializing on the image and then I import it into Premiere. However this also makes a problem when you want to move objects on the screen as the imported images which are doubled size, won't show well on the 1:1 pixel grid when you move them around the screen. So let's say each move on the X axis to the left or right (which represents a move by 1 pixel) should be moved twice in order to meet the doubled sized images pixel grid.
    Take a look on the picture I created to see what I mean. I've duplicated the box image and I'm trying to position each box one next to another in a 3d space look. The left boxes is the original image of the 2 boxes, and the right image is the doubled sized image that was created outside of Premiere. Please note that I've the entire screenshot twice larger so you could see the difference. And please ignore the fact that there is no antializing on the right image as I made this simulation in Photoshop so the pixels will be clean to show the problem.
    So, if you aware of how a pixel grid looks like, check the left image. The position of the boxes on each other is the way it should be as each pixel from each box keeps the relation of a 1:1 pixel grid. However on the right image I first doubled the original box image to prevent 'blurring' effect when scalling up in Premiere, put it on a 1:1 pixel canvas (where the image has 2:2 pixel grid by now) just like how it will be in Premiere, and tried to position the boxes one next to another. See that there's a confusion between the pixels on the 1:1 grid as they got merged one INTO another without saving the relation of a doubled pixel grid. Where if there was any option to work in doubled sized pixles in Premiere, it would have look like this:
    So importing a doubled size images into Premiere like you suggested is way hard to keep tracking the moving objects in the scene, as you must remember to move them twice the times to each direction. Which means that if you want to move an object from one side of the screen to the other side, you'll have to do it frame by frame in a move of 2 pixels by frame, rather then positioning it in one place, make a keyframe, and then go to where the movement should end and place another keyframe.
    Hope now my issue is clear.
    All the best,
    Gal Shemesh

  • I am missing the add objects section from the fly out menu in Photoshop CS6. 3d workspace

    I am missing the "add objects" section from the fly out menu in Photoshop CS6. I am in the 3D workspace of Photoshop. "Scene" is highlighted and I have clicked on the little fly out menu in the upper right hand corner of that panel. The whole section that should contain, Add objects, delete objects, duplicate objects, all the way through reverse order is missing. The add lights section above and render section below it is there. I am not new to Photoshop, but I am new to the 3D section of Photoshops work space.

    I've made tests with four different 3rd party tools: OpenGL Extension Viewer, GPU Caps Viewer, Compute4Cash OpenCL Diagnostic Tool and Mudlord's Glide3x wrapper tester. All those tools report no problems with my video card driver and OpenGL/CL.
    I have contacted nVidia and based on reports from the tools and visual tests from GPU Caps Viewer nVidia support doesn't see a problem with my driver.
    I found sniffer_gpu.exe which according to Adobe Help pages is a kind of diagnostic tool and determines whether Photoshop uses the graphic card OpenCL or not. Here is the output:

    On the other hand, I have your word that there is no problem with Photoshop not recognizing OpenCL for my card and that nVidia driver has problems. Can you justify this somehow? Perhaps you could provide more details on technical level, or another utility to run and extract details, to at least identify the problem Photoshop has and hopefully solve it on either side.
    P.S. During tests there were two things which I noticed, but they are probably not related to the issue:
    1. One tool reports the lack of Windows registry key SOFTWARE/Microsoft/Windows (NT)/CurrentVersion/OpenGLDrivers. But according to your previous statement, Photoshop only uses OS calls, no registry and according to nVidia, this key is not used in Windows 7.
    2. During some tests GPU Caps Viewer reports that "OpenCL CPU not supported on the selected platform". This is not complaining about GPU, only about CPU. But Photoshop is complaining about GPU, so it shouldn't be relevant.

  • Using BlackMagic Intensity Pro Video Compression card with FCP in a MacPro

    BlackMagic is offering the Intensity Pro card that they claim is enhancing the quality of video compression for better results than software driven compression, even with Standard DV in addition to HDV, and at a surprisingly cheap cost (less than $300).

    As someone used such hardware driven compression card in a MacPro ?
    Does-it really help making better quality DVDs?
    If not are there better hardware driven compression card?

    7-8 years ago, we said that analog video was at the low end and DV was at the high end.
    Uh, DV was NEVER on the high end. Digibeta and Beta were analog, and were HIGHER end than DV. Just because it was digital doesn't mean it was better. DV is compressed 5:1 and has 4:1:1 color sampling. Beta was 4:2:2 and better than DV...and Digibeta was and still is the high end SD format. DVCPRO 50 a close second. No...DV came in on the low end...like HDV comes in on the low end of the HD spectrum.
    If this Intensity card does not help to get better compression than software driven compression, is there another card which can do so ?
    Well, I answered this, but you must have missed my answer, so I will bold it for you: *THERE IS NO CARD OUT THERE FOR THE MAC THAT WILL AID IN DVD COMPRESSION.* I don't know about the PC side, so I make the statement to include MAC only. There are several hardware solutions for encoding DVDs that distributors use when making the theatrical DVDs like OCEANS 13...but those are separate hardware encoders. And no, again, those encoders are not available on a Mac.
    What I mean at the end is to find ways to have higher quality DVDs than when using software such as Compressor. Do you follow me ?
    I follow you....you aren't following me. Since I am an editor and not a distributor, I don't know what those solutions are. They exist outside of the editing world, so you have to GOOGLE this or look elsewhere. Needless to say, the Intensity does not aid in this. No capture card does. That is not what they are designed for. They are designed to capture non-firewire formats and to output to non-firewire formats...not to aid in DVD compression.
