But thanks for the post. I'm just starting to teach myself OpenCV to do some facial recognition stuff just as a proof of concept. The info here helped a bit.

I would like to work with python and pygame. At home i have and o'reilly book: "Learning OpenCV<br />Computer Vision with the OpenCV Library" which doesn't teach much about computer vision it focus more about teaching us how to use the OpenCV library using C. Thank you for the help, regards joãoUnknownhttps://www.blogger.com/profile/03171386142653360127noreply@blogger.comtag:blogger.com,1999:blog-2187247257118921242.post-68458323372416858482009-05-04T20:23:00.000-07:002009-05-04T20:23:00.000-07:00Hello, I made another manual to build python bindi...Hello, I made <A HREF="http://worldawesome.tistory.com/7" REL="nofollow">another manual</A> to build python binding of OpenCV in Mac OS X.Jinho Yoohttps://www.blogger.com/profile/08235170696178187963noreply@blogger.comtag:blogger.com,1999:blog-2187247257118921242.post-85715515739215288952009-01-19T22:43:00.000-08:002009-01-19T22:43:00.000-08:00Hi !Yeah, actually, it would be better to use unco...Hi !<BR/>Yeah, actually, it would be better to use uncompressed video, since it would be very easy to save as a file, and then reload it to start over from where you left it. An other solution would be to use the cpickle module - and maybe an other application to convert that cpickle file to an actual movie - but it might be slower that way.<BR/><BR/>To be continued. <BR/><BR/>Meanwhile, I have embedded toonloop.py into twisted, and added some command line options.

If you need video writing, you should currently configure for ffmpeg or xine and disable QuickTime. The downside of this is that you will lose QuickTime video input at the same time. And still ffmpeg video writing support is as buggy on Mac OS X as it is on Linux (for OpenCV). Volunteers?</I><BR/><BR/>...that means it is not possible to save movies, unless doing a hack. That would involve copying the frames in Python memory and saving it in a movie using the ffmpeg Python bindings. <A HREF="http://code.google.com/p/pyffmpeg/" REL="nofollow">The pyffmpeg project</A> doesn't look too much active, though.Alexandre Quessyhttps://www.blogger.com/profile/05136699443330771007noreply@blogger.com
