I have a web cam watching a test rig, and i have a Data acquisition system recording data from several sources, all running in windoze......
The Aquisition currently uses a simple application (coded in visual studio) to grab chunks of data from the various sources (mostly streamed over serial links) stick them all together and write them to a .csv file at around 10 Hz.
How hard would it be to write something to overlay some of the data onto the video stream in near real time? Even a 2hz update would probably be fine? Does something like this exist already? I can find programs like
http://www.dashware.net/ that do it in "post process" but i wondered if anything exists to do in real time in Windows?. My data application could just write a single line .csv every so often with the latest data in it, and the overlay application could parse the data out of that file and overlay it?
Sounds easy huh? Anyone done this before?
