I built my own PVR that captures video.  I used a Hauppauge tv card along with GBPVR.  The card $100 GBPVR free!

I have one of these cards laying around collecting dust, How is this working out for you quality wise. Is the frame rate acceptable with this card. Also, how much system resources does it use since I dont believe that mine has a lot of processing power on the board.  Any info would be greatly appreciated.

I scoured archives for some recommendations for external video capture devices (for working with composite video sources).

What are my chances of getting processing (Capture/JMyron) working with a external PVR style capture device (USB2.0/IEEE1394).  I'm ignoring fire-wire because my PC laptop doesn't have it.

Am I better off purchasing a USB model that only does software encoding, hence the uncompressed stream  Or is that a non issue

Are there any key words to look for in the tech specs on the models that would be a good clue  Specific model experiences

I don't mind blowing 20$ on webcams to trial, but 100+ on a capture device is another story and seek any advice.

Thanks in advance.

PS, reason for this approach is because the model cameras I want to experiment with are all composite only.  I already have a webcam+processing combination functioning.

No matter what capture device you use to capture your video it is best to stop all unnecessary programs and applications to help your computer capture at its best.

The above more than applies if you are capturing from an analog source, since many computers tend to drop lots of frames on analog capture.

Other things that help:

Defrag your computer before starting capture.

Do a test run to see what is the largest video size you can capture without droping too many frames. Usually a small video size will drop much less frames than a larger one. See what is your happy spot.

Hope this helps!

Hi there, i m wanting to link 4 IP cameras to processing.

I m trying to access the path of my ip cameras , one is seen below,however there is a problem with the access viewing the live  video stream,

DESPERATE FOR ANY HELP TO MOVE THIS FORWARD AS TIME IS RUNNING OUT

I need to get a decent webcam for testing/developing and would love to hear what models people are using and recommending. Right now I don't mind spending around 100€ but I'd like to go for something that works both on Windows and Mac.
Any suggestions?
