• How to start and stop the video capture in a state machine

  Hello

  I am a student of neuroscience and this is what I try to do: 1) trigger a camera to GigE (200 FPS), 2) start the video capture, 3) triggers a light that stays on for x milliseconds, 4) trigger a valve that will blow an air puff, 5) stop the tone and the valve at the same time and 5) stop the video capture 1 second after 4). For this, my VI is a state machine, with a State for each trigger (ex, 1 State for trigger camera 1 State of light of trigger, ect) and a statement to "stop" and a "time-out State." Everything worked except the video acquisition - the program could trigger the camera but only acquire a frame, because it was not running in a while loop and this is my first question: for an acquisition video is it always necessary to have a while loop?
  I guess the answer is Yes, so I built a loop of 'consumer' for the camera. A queue of the pre-trial 'trigger camera' in the loop of producer, I was then able to start the video capture, but now the problem is to stop it at the right time. I have an another queue in the State of 'stop' in the loop of the producer, but is not able to start the State 'stop' in the loop of consumer, I think that maybe it's because the loop of consumer gets "stuck" in the whole loop.

  I hope you can help me, the VI is attached. Thank you!

  Hello

  First of all, in your loop producer: STATE 'Stop', you use the flushing line, then there is no need to use 'item queue at the opposite end. You can use the enqueue function.

  Secondly, you said "I moved the command stop inside the while loop as you said, but it did not work. But if you look closely, you moved "Enqueue function" inside the while loop. Instead you should use Dequeue function. Please, look at the picture I posted an orderly manner.

  And remove the circled (i.e. function. Enqueue function loop of consumption, where I wrote 'Why stop here').

  I already read the agreements loops but unable to understand exactly what it means please help me...

  They say individual loops must not be commercialy or other wise distributed...

  That means individual loop should not be used?

  Is the only thing you can NOT do: "Yes, I did these loops and now I'm selling you these loops, claiming that I just them.»

  So they are free, but you are not allowed to sell unaltered loops claiming that make them you. So you can use them for any kind of music, published published, obscure, commercial, anything; without additional costs or restrictions.

• Date and time do not appear on the video captured in first Elements 9.

  Is it possible to get the timestamp to show up on the video captured from an older model mini Sony TRV18 camcorder DV?

  I can see the stamp date and time during playback of the video from the camcorder, but no time stamp appears in the clip mode capture first, or on the captured AVI file.

  I have the first Elements 9. If it is not possible in first 9, any suggestions for capture software where can I get the date stamp and time would be appreciated.

• Satellite Pro L300 - no video capture hardware

  Hi all, I'm new to the Forum so apologize me if this question has already been answered previously.

  I am trying to connect a USB Webcam to my Satellite Pro L300-153. Wizard installs the webcam and updates the drivers etc, but trying to work webcam a mistake happens "* webcam works not properly no video capture hardware detected."

  Can someone advise please. Thanks for your help.

  Hey Buddy,

  In my opinion, you must contact the manufacturing of this USB webcam. I put t know which model you have, etc. and there it s a Toshiba forum so I think that no one can tell you if it s associated with driver problem or camera itself.

  But I put t understand why do you use an external webcam. AFAIK all Satellite L300 are equipped with internal webcam

• Crop video captures all

  Hello gentlemen,

  For my project I undertake acquistion PPG without contact. I am trying to capture my webcam, but with all of the image, I get a lot of noise in the signal. I found using code samples provided by my supervisor in MATLAB that my webcam is capable of recording at 30 fps.

  I joined a video capture for treatment in other programs. Currently, the VI records to a text file.

  How would you suggest that I crop the video images before being caught or processed, I need this for two reasons, 1. the entire image generates noise and 2. reduce the footprint of output file.

  I have attached the VI for reference. To run a file in the file path text must be designated for the VI to run and a session for your WEBCAM.

  Regards Sean

  P.S Vision required.

  If you open your camera in MAX, there may be for the width and height properties. You can create a property on your in camera session node and to use these names as 'active' attribute, and then set the 'value' with a string or numeric.

  

• video capture of the Web cam

  I developed a VI in labVIEW 8.6 for webcam video display using IMAQ USB. However when I run the program it works well, but after I have stop for the first time that he refuses to work longer, except that I close this program and it all over again.

  I have attached the VI. I need help pls.

  Chiji

  It seems to work ok here.

  Are you using the stop button (to get out of the loop and close the camera) or stop the VI directly?

  Doing the first will allow to click on run again and it will resume streaming, making the latter kill him than the camera not be closed properly etc..

• Qosmio G30-155: video Capture does not work using s-video in port

  Toshiba Qosmio G30-155 video capture does not work via the ports of the video (Windows Vista Ultimate x 86) victory of version 3.90 BIOS
  Video capture does not work in Windows Media Center, even if selected as ports of entry port composite or s-video in Windows Media Center settings.

  In the BIOS version 3.90 parameters via esc - F1 can only select this option: NTSC (USA), NTSC (Japan), PAL (S-video).

  It is worth noting that the laptop is supposed to be capture NTSC for composite input mode

  Someone turned to make this model of video capture for laptop, via composite video input with the new version of the BIOS (version 3.90 win)?

  Can you please explain what you want to do exactly?

  Many years ago I had this old Qosmio with TV tuner and antenna in port so I used it to transfer my old VHS format videos and burn movie DVDs.

  To this end, I didn't use Windows Media Center. Why you n t use other recording applications. I think that everyone is better than Windows Media Center.

• SHOWBIZ DVD 2 analog video capture on my E10

  ShowBiz DVD 2 analog video capture on my E10.

  Stu

  Eric, I really don t understand you. First Movie Maker is part of the Microsoft software and you get it with Windows XP. What producer can do is to test it with own product. I'm sure you know that Movie Maker is developed for editing movies and not for recording of TV programs. WinDVD creator is also very good for editing movies.

  Second, you cannot say that you cannot save your favorite TV channel. This function is also integrated into WMC. If you don't like it, or you are not satisfied, you must look for the best solution.

  The same thing has been with me. I was not satisfied with the program to burn and I bought a new one with more options.

  Good bye

• No sound with video capture on Qosmio using Showbiz DVD, WinDVD, etc..

  Hi all

  {Apolgies initially... this announcement became long enough...)

  I have a Qosmio G10 and share the problem a lot seem to have with the version of the software Win DVD Toshiba: I can't capture video either windows througn or using Media Center installed WinDVD software. I followed the advice of the users of the forum and have tried the two Showbiz DVD and a freshly downloaded version of WinDVD and have made some progress in what I can see now the captured image. However, I get no sound.

  I tried the following mounting: the Qosmio is attached to the VCR via an S-video cable. Attempt to acquire sound (and maybe that's where I'm wrong) I fell normal RCA cable with the red and white Sockets out of VCR and (via an adapter to convert in one take) on Microphone Jack on laptop. No sound, so I tried the helmet in place. Within the Showbiz DVD I tried several Audio Options with boths taken, including the options microphone and Line-In. No sound. Having failed here, I tried to capture the video using the monitor instead of S-video port. Once again, with the software, I could see captured image but no sound. I also made sure my line volume parameter has not been set to "Mute". (I tried to capture with s-video on my desktop successfully using a wiring, although the video card and the software is different).

  Any advice? Especially those of you who have had success with Showbiz or WinDVD with S-video installation? Am I right to assume that, on the Qosmio, Microphone Jack double: Line-In jack and the double Headphone Jack Line Out? I can play a DVD on laptop and port of exit of sounds and images on television. Is it possible that the map of its Qosmio is not able to port in the sound? Is it because I'm not going through the TV Tuner somehow? What is the relationship of the TV Tuner sound and installation of capture/entertainment Qosmio together? I tried this in both Windows and Media Center.

  Advice from colleagues Qosmio optical users appreciated.

  I like this laptop, but I am very displeased with Toshiba in what concerns the fact that the Qosmio is so heavily planted as an entertainment center and still has so many problems associated with these same functions (and recharge much moe on the 'resistance' of them). Beyond software WinDVD does not (and strangely different then the version apparently even available on the WinDVD site) I had trouble with TV Tuner, among other things.

  Once again, help is much appreciated.

• Satellite Pro A60 video Capture problems

  I have the following system:

  Toshiba A60 laptop Pro satellite
  CPU - AMD 2.8 Ghz
  RAM - 768 MB
  OS - XP Pro SP2

  All other system requirements as indicated by the Dazzle DVC90 USB 2.0 capture card are met.

  I use Pinnacle Studio 9.4 update to capture VCR.

  Problem:

  When I plug the DVC90 to my laptop, I get nothing on the preview window. I have it set to capture as quality DVD Mpeg. But I don't see a gray screen when I look at the overview. I click start capture, the timer starts but no capture is made, either by audio or video.

  I checked all the settings. They all seem to be fine. My friend tried the capture card USB with exactly the same settings and connection on his desktop PC and it worked perfectly. The specification of his PC is similar to my laptop. Is it a familiar fault with video capture on laptops?

  I'd appreciate it if someone could help me with these problems.

  Thank you very much

  Alex

  Hi Alex,

  Have you checked in your Pinnacle capture settings that is not failing to the incorrect entry (rather than Composite, S-video). Obviously the value specified must match your connectivity of material allowing to receive a video signal.

  I think that it is also possible to disable the capture preview screen to minimize the risk of frame drops. Please check that you have the active video preview.

  Hello

  You need an application to capture the video stream from a video of input material source.  This Roxio product should work.  If your PC has Cyberlink products then you will maybe upgrade the software and get a capture device similar to the capture of Roxio hardware.
