Video stream capturing
« on: June 18, 2007, 03:31:10 pm »
How to implement video stream capturing (displaying on screen with subsequent calculations) from USB-webcam in Lazarus application? Prefferably platform-independent.
I read something about "gstreamer" lib but i can't imagine how to  use it in Lazarus app.
Maybe somebody knows working examples?

AFAIK, it is. It was not clear from your post, you needed a non-windows solution.

Are you sure gstreamer is a video capturing library? On their website they claim it's a video playing library.

I guess that the steps to get what you want accomplished are:

1 - Find a library that does what you want. Google is your friend

2 - Convert the bindings of the library to Pascal, if there aren't already translations available

3 - Find out how to use the library

4 - Integrate it with your Lazarus application

A SysRec doesn't works for me. I tested on two real webcams and some virtual ones. Just a black screen.
