Where is ffmpeg installed on mac

If you are only using StereoMorph with photographs not video then this section can be skipped. As of version 1. This includes calibrating two video cameras using video files, rather than using a set of photographs or already extracted frames from each video. R does not have native support for reading frames from video files. Thus, a codec library must be installed in order for StereoMorph to extract frames from video files. Once the codec is installed and accessible from the command line, all video handling can be done within R.

This section will show you how to install the video codec library ffmpeg. Currently, these ffmpeg installation instructions are only suitable for Mac OS X. Download the latest static build of ffmpeg for your operating system less than 80 MB unzipped. On the ffmpeg download site you'll find links to the static builds under "Get the packages". For example, the most recent static build for Mac OS X can be downloaded here.

The downloaded static build should be a compressed folder. Unzip this folder. Inside you should see an executable named "ffmpeg" and possibly also "ffprobe" and "ffserver", which we do not need. On Ubuntu, you can install FFmpeg in a couple of ways — using the apt package manager or compiling from source. However, if you are installing FFmpeg on an Ubuntu machine, there is a high likelihood that you are going to tinker with FFmpeg and that means you might want to compile from the FFmpeg source.

Here is my procedure for compiling and installing FFmpeg from source on Ubuntu Step 1: Install the Dependencies including nasm. And, remember to create the following folders. Step 2: Install the Video and Audio Codecs that you are going to need. I installed libx , libxdev , libnuma-dev , libvpx-dev , libfdk-aac-dev , libmp3lame-dev , and libopus-dev.

FFmpeg only provides source code. Below are some links that provide it already compiled and ready to go. You can retrieve the source code through Git by using the command:. FFmpeg has always been a very experimental and developer-driven project.

It is a key component in many multimedia projects and has new features added constantly. Since FFmpeg is developed with Git , multiple repositories from developers and groups of developers are available. All FFmpeg releases are cryptographically signed with our public PGP key and should be verified for authenticity. Approximately every 6 months the FFmpeg project makes a new major release.
