I am using mac os x 1.7.5 with python 2.7.51 and opencv 2.4.40 installed via macports. I am using python 2.7.1, opencv 2.3.1a, and the python wrappers from willowgarage that come with that version of opencv.Click here to download the source code to this postUnable to write video using python and opencv2 on mac os x.

Video Codec Opencv Series Of BlogIn most cases you’ll be pulling down the repo, installing prerequisites, compiling by hand, and hoping that your installation goes smoothly.With OpenCV 3.0 it doesn’t get any easier — and there are definitely some caveats and gotchas that you need to look out for (such as the opencv_contrib repository — without it, you’ll be missing out on some important features, such as SIFT, SURF, etc.)But don’t worry, I’ve got you covered! Just keep following along with the PyImageSearch blog and I promise these tutorials will get you up and running with OpenCV 3.0 in no time.We’ll go ahead and kick-off our OpenCV 3.0 install fest by installing v3.0 with Python 2.7+ bindings on the OSXplatform.If you’re an Ubuntu or Raspberry Pi user, be sure to keep an eye on PyImageSearch as I’ll be posting OpenCV 3.0 install instructions for Ubuntu and the Raspberry Pi as well.A quick note before we get started: While OpenCV 3.0 is indeed compatible with Python 3+, most computer vision developers are still using Python 2.7 (since OpenCV 2.4.X is only compatible with Python 2.7). It’s not like you can let pip or easy_install to the heavy-lifting for you. 83.100 libavdevice As I mentioned last week, OpenCV 3.0 is finally here!And if you’ve been paying attention to my Twitter stream, you may have noticed a bunch of tweets regarding installing OpenCV on OSX and Ubuntu (yep, I’ve been tweeting a lot lately, but that’s just because I’m so excited about the 3.0 release!)To celebrate OpenCV 3.0, I have decided to perform a series of blog posts that detail how to install OpenCV 3.0 on both Python 2.7+ and Python 3+.We’ll also be performing these Python 2.7 and Python 3+ installations on a variety of platforms including OSX, Ubuntu, and yes, the Raspberry Pi.As I’m sure you already know, OpenCV has never been an effortless library to install. Use m4vgear for mac to record netflixHow to Install OpenCV 3.0 and Python 2.7+ on OSXThis is our first tutorial in our OpenCV 3.0 install-fest series. This tutorial still works perfectly if you are using OSX Yosemite or prior, but if you want to install OpenCV on the newer El Capitan and macOS Sierra please use this freshly updated tutorial. But for now, let’s stick with what we know and use Python 2.7.UPDATE: The tutorial you are reading now covers how to install OpenCV 3.0 with Python 2.7 bindings on OSX Yosemite and below. Hp laserjet 4000 driver for macAnd this is especially true if you intend on using virtualenv and virtualenvwrapper (which we will be).Let’s go ahead and use Homebrew to install our user-specific version of Python 2.7: $ brew install pythonNote: This tutorial will be covering how to install and setup OpenCV 3.0 with Python 2.7. These formula are simply instructions on how to install a given package or library.To update Homebrew, simply execute: $ brew updateIt’s bad form to use the system Python as your main interpreter. Think of Homebrew as an (almost) equivalent of apt-get for Ubuntu.To install Homebrew, simply head to the Homebrew website and simply copy and paste the command underneath the “Install Homebrew” section into your terminal: $ cd ~Now that Homebrew is installed, you’ll need to update it and grab the latest package (i.e. Step 2:Now that Xcode is installed, we need to install Homebrew, which is labeled as “The missing package manager for OSX” (and they really are not joking about that one). From there, just click Get and Install App (and when prompted, you’ll need to enter your Apple ID username and password): Figure 1: Installing Xcode on your OSX system. Step 1:The first step we need to do is install Xcode, which is a combination of IDE and software development tools for developing applications on the OSX and iOS platforms — most of us already have Xcode installed.But if you don’t, you’ll want to open up the App Store application and search for Xcode. ![]() These packages allow you to load various image file formats such as JPEG, PNG, TIFF, etc. We need to install NumPy since the OpenCV Python bindings represent images as multi-dimensional NumPy arrays: $ pip install numpyUp until this point we have been mainly focusing on actually setting up and configuring our development environment to compile and install OpenCV — here is where the real work starts.First, we’ll use brew to install the required developers tools, such as the wonderful CMake utility: $ brew install cmake pkg-configAnd here we are going to install the necessary image I/O packages. Step 5:Now we can start installing some Python packages. The cv virtual environment is where we’ll be doing all of our computer vision development (and not to mention, compiling OpenCV 3.0 with Python 2.7+ support). ![]()
