OpenCV 4 is packed with new features, many of which are deep-learning focused. => Pouring cmake-2.8.12.2.mavericks.bottle.2.tar.gz In this blog post we’re going to install OpenCV 4 on macOS. => Installing dependencies for opencv: cmake, libpng expect a ton of very helpful warnings and complicated-looking output, followed byĮxport PYTHONPATH=/usr/local/Cellar/opencv/2.4.7.1/lib/python2.7/site-packages:$PYTHONPATHįinally, in a new terminal window: brew install opencv ➜ we-main git:(feature/112-org-thumb) ✗ brew install opencv
For using non free codecs, you can compile OpenCV yourself (which takes time) or you can pipe OpenCV with FFMPEG. This is my Gstreamer pipeline SEND script line: gst-launch-1.0 -v v4l2src video/x-raw,width320,height240 videoconvert jpegenc rtpjpegpay udpsink host192.168.1. I have a working Gstreamer pipeline from my raspberry pi 3b to Ubuntu 16.04. By default OpenCV is shipped with royalty free codecs only. I have OpenCV installed with ffmpeg and gstreamer support. pip3 install opencv-python About OpenCV & codecs. If your py is in good shape you may be able to skip down to 'brew install opencv'. On mac, you can run : brew install ffmpeg OpenCV-python installation. brew tap homebrew/science brew install opencv -with-ffmpeg.
Install Homebrew if not already installed.
