Re: [osg-users] Quicktime plugin live streaming documentation/examples
Hi any demo / example ? regards 2008/4/3, Mike Greene [EMAIL PROTECTED]: Colin, Success! Using the later version of VDIG that you referenced, I was able to get a live stream to work with osgmovie. I'm using a KOCOM camera running video through a Canopus ADVC 110 A/D video convertor into a firewire cable. This is on Windows XP, OSG 2.3.5, Visual Studio 2005 debug, Quicktime SDK 7.3.

Re: [osg-users] Quicktime plugin live streaming documentation/examples
Hi Adrian, I've not documented anything on the wiki yet but below is how the result was achieved on Windows XP. See my previous post for any more detail. The demo/example is really just a quad with your live feed playing - so a I've just tweaked osgmovie here to force load the plug-in from a .live association and then interpret the file basename to get a device and input ID - ugly but working... 0. If you have NO QuickTime driver for your device then install http://www.abstractplane.com/products/vdig.jsp Use the latest version and do the manual install from the zip. You will jave to live with the demo mode or fork out some $$$. If your capture device has a QuickTime driver then you do not need this VDIG for Windows thing eg BlackMagic Intensity Pro. 1. Modify the osgmovie.cpp and make sure that the .live extension is associated with the osgdb_qt plugin: osgDB::Registry::instance()-addFileExtensionAlias(live,qt); 2. run osgmovie --devices If you have any live feed devices associated with a QuickTime driver then this will spit out some command line options and associations. It will also spit out any pseudo Windows VDIG wrapped Direct Show devices in the same way eg: ... 4:1.liveBlackmagic HDTV 720Intensity HDTV 720p 59.94 ... 1:4.liveHauppauge WinTV 418 Video Capture (4E384A6E048F0)S-Video 3 UYVY @ 720x480 ... 3. run osgmovie and pass it a pseudo file name that will be translated by the plug-in to point at an input device eg $ osgmovie x:y.live This will force load the osgdb_qt plug-in, and then attempt to decode the x:y.live where x and y are the input and channel of your input - eg 5:0.live I plan to submit to Robert an osgvideo example which wraps some of this up a bit better.

Re: [osg-users] Quicktime plugin live streaming documentation/examples
Hi Mike, you might want to look here for some more tips: http://processing.org/reference/libraries/video/ Prior to getting a capture card that shipped with a proper QuickTime vdig supported under under Windows XP and XPx64, I also tried a Windows wrapper called WinVDIG which I got from here: http://www.eden.net.nz/7/20071008/ However I found this version also crashed when responding the the QuickTime vdig API calls upon it. Also play close attention to the removal instructions for this stuff as it took me quite a while to clean my machine of WinVDIG and the crashes. Anyway the long and short of it is avoid this version and see below... Stephan wrote: For windows there's one I know of available at http://www.abstractplane.com/products/vdig.jsp I plan to give this other Windows VDIG wrapper from AbstractPlane a go and see if I can help you to track the bugs. It looks far more up to date than the other one and apparently works with QuickTime7. This would be your best solution in the short term and I'll get back to you on this ASAP. The long and short of it is that I found the whole QuickTime SDK and integration with OSG quite a different experience under Windows and OSX. Pending some further funding and time I'd like to extend the current work to upgrade the live/stream work to use optionally DirectShow on Windows, and therefore free up the OSX version to use the newer OpenGL/CoreVideo/Movie QT7 stuff - right now they both share some old-style GWorld SequenceGrabber code to make it work on both platforms - you could say equally well or equally badly - and it creaks - especially the live stuff...

Re: [osg-users] Quicktime plugin live streaming documentation/examples
OK, I've hooked a video input source up to my firewire card. I've made sure that the qt plugin can recognize (.live) extensions. When I run osgmovied.exe --devices, I get messages about QT QTML, QT Movies, and QT QTML (again) starting up and closing down successfully. But the last line output is : available Video DigitizerComponents : 0 I know the video is working because I have a VideoLan Client instance running and it shows the output of the camera feed. Is there there something else (maybe relative to QuickTime) that I need to specify?

On OS X there are built-in vdigs available for a lot of camera-models.

Re: [osg-users] Quicktime plugin live streaming documentation/examples
Hi Mike, yup right now it'll work from an attached device as Stephan said but in addition including a capture card, provided the device has a quicktime driver installed. When I wrote the live feed extension part of the work included support for a stream, however I did not get that far and the capture card was sufficient for the client. I wrote some documentation for the .live processing that Robert asked me to put on the wiki - so I should do that tomorrow if you think it would be of use to you. Are you on Windows or Mac BTW? Since you asked about the .live then A=as a ten second piece of documentation off the top of my head start by using a slightly modified osgmovie app until I submit the osgvideo example: 0. Modify the osgmovie.cpp and make sure that the .live extension is associated with the osgdb_qt plugin: osgDB::Registry::instance()-addFileExtensionAlias(live,qt); 1. run osgmovie --devices If you have any live feed devices associated with a QuickTime driver then this will spit out some command line options and associations. eg: ... 4:1.liveBlackmagic HDTV 720Intensity HDTV 720p 59.94 ... 2. run osgmovie x.y.live This will force load the osgdb_qt plugin, and then attempt to open the x.y.live where x and y are the input and channel of your input - eg 5:0.live Sorry I can't help you regarding the streaming using QuickTime at this point in time.
