Post by thread:[OT]: Grabbing pictures from a USB webcam.

I need to grab a series of pictures from a USB webcam and analyse them in real time. (it's a Phillips vestacam, but that's probably not important). Does anyone have any ideas how actually grab the pictures? I need this to work on a Win98 platform. As I need to do the analysis on each frame as it comes in, saving the video to disk and then re-opening it is probably not an option. Most stuff I've seen so far wants to save video to disk No PIC in this at all, just hoping someone has done this before...... Thanks for any help Joe -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu

There is actually quite a bit of material on the WEB about this. THere is a standard interface that is camera independent. A description of the avi interface is here http://msdn.microsoft.com/library/psdk/multimed/avifile_8dgz.htm Borlands delphi site has VFW software interface examples written by J. Huebler. This includes source for frame grabbers and and frame savers. The file name is videocap.zip. It is a set of drivers with source and some examples of its use. Herr Huebler can be reached at .....hueblerKILLspam@spam@fbm.fh-weingarten.de I have used these routines. There are Visual Basic routines ezvidc60.zip and ezVidCap.zip at //http://www.shrinkwrapvb.com These were written by Ray Mercer <raymerKILLspamshrinkwrapvb.com> There is some java software at http://www.camcatcher.com although I have not used it.
