video capture in Python ?

[Stef Mientki]

hello,

has anyone got video capturing (from a webcam) successful running
in a wxPython application under winXP ?

I got some links, but it seems quit complicated to get everything
installed,
and all the packages you need don't describe which versions of the other
parts you need,
so a lot trial and error I expect.

thanks,
Stef Mientki

What packages have you tried?

videocapture
webcamwatcher
opencv
libvidcap
hdpvrassistent

they didn't run at all or they crashed within 10 seconds :-(
The most promissing looks videocapture, but that also crashes within 10
seconds.

Video capture is not a trivial task.

to be more exactly, I think you mean "it's not a trival task in Python"

I just created a Delphi project to select a video device, show the cam
image on the screen and store the movie in a file:
- less than 10 lines of code,
- less than 10 minutes of work
and the program looks rock stable !

So for this project I'll probably go back to Delphi ;-)

thanks,
Stef Mientki

Or C. OpenCV has nice examples.

For Video Capture, the external library needs to do most of the work
obviously, since this is the corner case for a scripting language.
(Even Delphi can be suboptimal depending on what you want to do
once you captured a frame)

I can say opencv worked great for me both on linux and windows
and didn't crash. Maybe you have just an unlucky combination
of drivers.
