MOV to AVI or intensity array?
Bill Gilbert posted a topic in Machine Vision and ImagingFor years now in the student labs we've used firewire video cams and the IMAQ 1394 driver to create AVI files which then get read and converted to intensity arrays for motion analysis in a Labview app. The cheap cams are going extinct, and they want to use I-pads to create the videos which are MOV Quicktime format. So far it looks like the I-pad app they want to use can't be made to spit out an uncompressed AVI. So now I need to find out if I can either: 1) automate conversion of an MOV to uncompressed AVI and continue to use our LV analysis app as-is, or 2) find a way to parse a compressed MOV video to a frame-by-frame intensity array, and build that into our LV analysis app. I am starting to search, but is anybody aware of an existing library or methods so I don't reinvent the wheel? Thanks, BG

I recently had a project dropped into my lap and have had a tough time finding information about it on the web. Here is a quick outline of my current issue. I am trying to take in an analog video signal (640x480) and process the stream in LabVIEW/IMAQ/IMAQdx (end goal would be to have uncompressed video being processed). I need to be able to have an uncompressed image to do calculations on. I am currently trying to achieve this by using an axis video server and converting the analog signal into a digital signal and finding the camera via an IP address (having networked video was requested as well... Not a must though). My understanding is that LabVIEW takes in the video stream as mjpeg (please correct me if I am wrong) and even at the lowest compression setting mjpeg streams are still compressed pretty heavily and use a lossy compression algorithm (again correct me if I am wrong) which will make doing any reliable image processing for me very difficult. So my question is... Is there a better way to do this using any other hardware? We will be putting the software on a pc like this, so I am unable to use pci/pci-e boards/cards but something through USB or Ethernet ports is fair game. I really appreciate any help I can get! I am using LabVIEW 2011 with Vision 2011
