New OpenCV 2.1 port

Reported by: ajb78@… Owned by: stante@…
Priority: Normal Milestone:
Component: ports Version: 1.9.1
Keywords: haspatch Cc:
Port: opencv

Description

While working with opencv, I realized that under mac os x there is a serious bug in VideoCapture that prevents capture from webcams. Details can be found ​here and ​here.

As noted in the first link there is a patch for it in SVN, which I've backported to the macports 2.1 version. Attached are the diff for the Portfile and the diff for the offending source file in opencv.

Theoretically OpenCV 2.1.1 will be out soon and it should fix this problem, so it may not be worth committing this port, but I wanted it out there.

FYI:"New OpenCV 2.1 port" is a pretty bad title for a bug report. "Unable to get video stream via OpenCV's C++ interface" or sth like that would be better.

I ran into this bug yesterday. Would be great if this patch will be included soon.
