ffmpeg golang binding

why a new goav fork?

• the google top goav result doesn't work anymore.
• a recent working fork I tested is here
• make it usable and compatile for FFmpeg 3.x or 4.x under ubuntu 18.04, 20.04

Dependencies

goav depends upon several libraries from FFmpeg (version 3.3 or higher):

• libavcodec
• libavdevice
• libavfilter
• libavformat
• libavutil
• libswresample
• libswscale

and a few other tools in general:

• pkg-config

Mac OS X

On Mac OS X, Homebrew saves the day:

brew install ffmpeg pkg-config

Ubuntu >= 18.04 LTS

On Ubuntu 18.04 LTS everything can come from the default sources:

### General dependencies
sudo apt-get install -y  pkg-config

### Library components
sudo apt-get install -y libavformat-dev libavcodec-dev libavdevice-dev libavutil-dev libswscale-dev libswresample-dev libavfilter-dev

Ubuntu < 18.04 LTS

On older Ubuntu releases you will be unable to satisfy these requirements with the default package sources. We recommend compiling and installing FFmpeg from source. For FFmpeg:

sudo apt install \
    autoconf \
    automake \
    build-essential \
    cmake \
    libass-dev \
    libfreetype6-dev \
    libjpeg-dev \
    libtheora-dev \
    libtool \
    libvorbis-dev \
    libx264-dev \
    pkg-config \
    wget \
    yasm \
    zlib1g-dev

wget http://ffmpeg.org/releases/ffmpeg-3.2.tar.bz2
tar -xjf ffmpeg-3.2.tar.bz2
cd ffmpeg-3.2

./configure --disable-static --enable-shared --disable-doc
make
sudo make install

See this script for a very detailed installation of all dependencies.

Windows

It is possible to build goav on Windows without Conda by installing FFmpeg yourself, e.g. from the shared and dev packages.

Unpack them somewhere (like C:\ffmpeg), and then tell goav where they are located.
