### Requirements



- FFmpeg with headers and shared libraries (2.4+)

- libargtable2 for option parsing

- Optional: SDL for building the Comskip GUI



### Building



#### Building from GitHub



Building directly from GitHub also requires GNU autotools (autoconf, automake, and libtool).



```

$ git clone git://github.com/erikkaashoek/Comskip

$ cd Comskip

$ ./autogen.sh

$ ./configure

$ make

```



#### Building from a tarball



```

$ tar zxpfv comskip-.tar.gz

$ cd comskip-

$ ./configure

$ make

```



### Setting up a build environment



#### Windows



There are many ways to setup a build system on Windows.



##### Cross Compile with Ubuntu Bionic (18.04) with MinGW-w64



```

$ sudo apt-get install -y subversion curl texinfo g++ bison flex cvs yasm automake libtool autoconf gcc cmake git make pkg-config zlib1g-dev mercurial unzip pax nasm gperf autogen bzip2

$ git clone https://github.com/erikkaashoek/Comskip.git

$ cd Comskip

$ ./cross_compile_comskip.sh

```



##### MSYS2 and MinGW-w64



These instructions use MSYS2 and MinGW-w64, but other environments should also work:



- Install MSYS2 by following the instructions at https://msys2.github.io/

- Install the essential build tools: `pacman -S mingw-w64-i686-gcc gcc make autoconf automake libtool pkgconfig yasm`

- Close the MSYS2 shell and launch a MinGW-w64 shell; this is the shell you'll use for all builds

- Build FFmpeg (http://ffmpeg.org/), argtable2 (http://argtable.sourceforge.net/) and SDL2 from source and install them to /usr/local

- Add /usr/local/lib/pkg-config to PKG_CONFIG_PATH (e.g., add `export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig` to ~/.bashrc, then type `source ~/.bashrc`)



#### Mac OS X



First install Xcode (freely available from the Mac OS X App Store). After it's installed, install the Xcode command-line tools by executing `xcode-select --install` from a terminal.



The easiest way to install Comskip's dependencies is via Homebrew (http://brew.sh/):



```

$ brew install autoconf automake libtool pkgconfig argtable ffmpeg sdl

```



[Macports](https://www.macports.org/install.php) natively compiles all libraries from source. The project [etv-comskip](https://github.com/essandess/etv-comskip) has an example [Makefile](https://github.com/essandess/etv-comskip/blob/master/Makefile) using Macports tools.



```

$ sudo port install ffmpeg coreutils argtable

```



#### Linux



##### Ubuntu Xenial (16.04)



```

$ apt-get install -y autoconf libtool git build-essential libargtable2-dev libavformat-dev libsdl1.2-dev

```



##### Ubuntu Vivid (15.04)



```

$ apt-get install -y git build-essential libargtable2-dev libavformat-ffmpeg-dev libsdl1.2-dev

```



##### Ubuntu Trusty (14.04)



```

$ add-apt-repository -y ppa:mc3man/trusty-media

$ apt-get update



$ apt-get install -y git build-essential libargtable2-dev libsdl1.2-dev

$ apt-get install -y ffmpeg libva-dev libsoxr-dev libvorbis-dev libbz2-dev zlib1g-dev libxvidcore-dev libvpx-dev libx264-dev libx265-dev libspeex-dev libfdk-aac-dev libvorbisenc2 libopus-dev libmp3lame-dev libdca-dev libfaac-dev libopencore-amrnb-dev libvo-aacenc-dev libopencore-amrwb-dev



$ git clone https://github.com/foo86/dcadec

$ cd dcadec

$ make install

```



##### Ubuntu Precise (12.04)



```

$ add-apt-repository -y ppa:pavlyshko/precise

$ add-apt-repository -y ppa:chris-lea/zeromq

$ apt-get update



$ wget https://launchpad.net/ubuntu/+archive/primary/+files/libfdk-aac0_0.1.1%2B20130514-2_amd64.deb

$ wget https://launchpad.net/ubuntu/+archive/primary/+files/libopus0_1.0.1-0ubuntu2_amd64.deb

$ wget https://launchpadlibrarian.net/205263953/libwebp5_0.4.1-1.2pmo1%7Eprecise_amd64.deb

$ dpkg -i libfdk-aac0_0.1.1+20130514-2_amd64.deb

$ dpkg -i libopus0_1.0.1-0ubuntu2_amd64.deb

$ dpkg -i libwebp5_0.4.1-1.2pmo1~precise_amd64.deb



$ apt-get install -y git build-essential libargtable2-dev libsdl1.2-dev

$ apt-get install -y ffmpeg-opti libavformat-ffmpeg-opti-dev

```



### Building static binaries



You can build a static binary by passing the `--enable-static` parameter to `configure`, but beware the following caveats:



- True static linking on Mac OS X is not supported by Apple. Do not use the `--enable-static` directive on OS X. Rather, use the script [matryoshka-name-tool](https://github.com/essandess/matryoshka-name-tool) to use OS X's `install_name_tool` to modify the comskip binary and create a directory of shared libraries that may be distributed to users without homebrew or Macports installations. The project [etv-comskip](https://github.com/essandess/etv-comskip) has an example [Makefile](https://github.com/essandess/etv-comskip/blob/master/Makefile) using matryoshka-name-tool.



- Some libraries have incomplete or incorrect dependencies listed in their pkgconfig files. If static linking fails on your system, you'll need to override these by manually specifying the `argtable2_LIBS`, `ffmpeg_LIBS`, and `sdl_LIBS` environment variables with the required list of libraries and their locations.
