We need CMake to configure the installation, GCC for compilation, Python-devel and Numpy for building Python bindings etc. I installed OpenCV with following these stpes. When I tried to check FFmpeg support with this command: python -c 'import cv2 print (cv2.getBuildInformation ())' grep -i FFmpeg it gave me NO result. You can skip optional dependencies if you don't want. Also, when I run ' make -j8 ' command, it finished with no problem. This tutorial shows how to install FFmpeg on Raspberry Pi. It allows to convert video and audio files from one format into another, resize videos, stream audio and video, and perform various other actions with media files. Building OpenCV from sourceĬompiling from source may seem a little complicated at first, but once you succeeded in it, there is nothing complicated.įirst we will install some dependencies. FFmpeg is an open-source collection of tools for processing video and audio files. Also at some point in time, if you want to contribute to OpenCV, you will need this. So for getting latest source codes preference is next method, i.e. With respect to Python API, latest version will always contain much better support and latest bug fixes. For example, at the time of writing this tutorial, apt repository contains 2.4.8 while latest OpenCV version is 3.x. Apt repositories may not contain the latest version of OpenCV always. If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully.
