## 1 External libraries# TOC

FFmpeg can be hooked up with a number of external libraries to add support for more formats. None of them are used by default, their use has to be explicitly requested by passing the appropriate flags to `./configure`.

### 1.1 OpenJPEG# TOC

FFmpeg can use the OpenJPEG libraries for encoding/decoding J2K videos. Go to http://www.openjpeg.org/ to get the libraries and follow the installation instructions. To enable using OpenJPEG in FFmpeg, pass `--enable-libopenjpeg` to `./configure`.

### 1.2 OpenCORE, VisualOn, and Fraunhofer libraries# TOC

Spun off Google Android sources, OpenCore, VisualOn and Fraunhofer libraries provide encoders for a number of audio codecs.

OpenCORE and VisualOn libraries are under the Apache License 2.0 (see http://www.apache.org/licenses/LICENSE-2.0 for details), which is incompatible to the LGPL version 2.1 and GPL version 2. You have to upgrade FFmpeg’s license to LGPL version 3 (or if you have enabled GPL components, GPL version 3) by passing `--enable-version3` to configure in order to use it.

The Fraunhofer AAC library is licensed under a license incompatible to the GPL and is not known to be compatible to the LGPL. Therefore, you have to pass `--enable-nonfree` to configure to use it.

#### 1.2.1 OpenCORE AMR# TOC

FFmpeg can make use of the OpenCORE libraries for AMR-NB decoding/encoding and AMR-WB decoding.

Go to http://sourceforge.net/projects/opencore-amr/ and follow the instructions for installing the libraries. Then pass `--enable-libopencore-amrnb` and/or `--enable-libopencore-amrwb` to configure to enable them.

#### 1.2.2 VisualOn AMR-WB encoder library# TOC

FFmpeg can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.

Go to http://sourceforge.net/projects/opencore-amr/ and follow the instructions for installing the library. Then pass `--enable-libvo-amrwbenc` to configure to enable it.

#### 1.2.3 Fraunhofer AAC library# TOC

FFmpeg can make use of the Fraunhofer AAC library for AAC encoding.

Go to http://sourceforge.net/projects/opencore-amr/ and follow the instructions for installing the library. Then pass `--enable-libfdk-aac` to configure to enable it.

### 1.3 LAME# TOC

FFmpeg can make use of the LAME library for MP3 encoding.

Go to http://lame.sourceforge.net/ and follow the instructions for installing the library. Then pass `--enable-libmp3lame` to configure to enable it.

### 1.4 TwoLAME# TOC

FFmpeg can make use of the TwoLAME library for MP2 encoding.

Go to http://www.twolame.org/ and follow the instructions for installing the library. Then pass `--enable-libtwolame` to configure to enable it.

### 1.5 libvpx# TOC

FFmpeg can make use of the libvpx library for VP8/VP9 encoding.

Go to http://www.webmproject.org/ and follow the instructions for installing the library. Then pass `--enable-libvpx` to configure to enable it.

### 1.6 libwavpack# TOC

FFmpeg can make use of the libwavpack library for WavPack encoding.

Go to http://www.wavpack.com/ and follow the instructions for installing the library. Then pass `--enable-libwavpack` to configure to enable it.

### 1.7 OpenH264# TOC

FFmpeg can make use of the OpenH264 library for H.264 encoding and decoding.

Go to http://www.openh264.org/ and follow the instructions for installing the library. Then pass `--enable-libopenh264` to configure to enable it.

For decoding, this library is much more limited than the built-in decoder in libavcodec; currently, this library lacks support for decoding B-frames and some other main/high profile features. (It currently only supports constrained baseline profile and CABAC.) Using it is mostly useful for testing and for taking advantage of Cisco’s patent portfolio license (http://www.openh264.org/BINARY_LICENSE.txt).

### 1.8 x264# TOC

FFmpeg can make use of the x264 library for H.264 encoding.

Go to http://www.videolan.org/developers/x264.html and follow the instructions for installing the library. Then pass `--enable-libx264` to configure to enable it.

x264 is under the GNU Public License Version 2 or later (see http://www.gnu.org/licenses/old-licenses/gpl-2.0.html for details), you must upgrade FFmpeg’s license to GPL in order to use it.

### 1.9 x265# TOC

FFmpeg can make use of the x265 library for HEVC encoding.

Go to http://x265.org/developers.html and follow the instructions for installing the library. Then pass `--enable-libx265` to configure to enable it.

x265 is under the GNU Public License Version 2 or later (see http://www.gnu.org/licenses/old-licenses/gpl-2.0.html for details), you must upgrade FFmpeg’s license to GPL in order to use it.

### 1.10 kvazaar# TOC

FFmpeg can make use of the kvazaar library for HEVC encoding.

Go to https://github.com/ultravideo/kvazaar and follow the instructions for installing the library. Then pass `--enable-libkvazaar` to configure to enable it.

### 1.11 libilbc# TOC

iLBC is a narrowband speech codec that has been made freely available by Google as part of the WebRTC project. libilbc is a packaging friendly copy of the iLBC codec. FFmpeg can make use of the libilbc library for iLBC encoding and decoding.

Go to https://github.com/TimothyGu/libilbc and follow the instructions for installing the library. Then pass `--enable-libilbc` to configure to enable it.

### 1.12 libzvbi# TOC

libzvbi is a VBI decoding library which can be used by FFmpeg to decode DVB teletext pages and DVB teletext subtitles.

Go to http://sourceforge.net/projects/zapping/ and follow the instructions for installing the library. Then pass `--enable-libzvbi` to configure to enable it.

### 1.13 AviSynth# TOC

FFmpeg can read AviSynth scripts as input. To enable support, pass `--enable-avisynth` to configure. The correct headers are included in compat/avisynth/, which allows the user to enable support without needing to search for these headers themselves.

For Windows, supported AviSynth variants are AviSynth 2.6 RC1 or higher for 32-bit builds and AviSynth+ r1718 or higher for 32-bit and 64-bit builds.

For Linux and OS X, the supported AviSynth variant is AvxSynth.

There is currently a regression in AviSynth+’s `capi.h` header as of October 2016, which interferes with the ability for builds of FFmpeg to use MSVC-built binaries of AviSynth. Until this is resolved, you can make sure a known good version is installed by checking out a version from before the regression occurred:

`git clone -b MT git://github.com/AviSynth/AviSynthPlus.git
cd AviSynthPlus
git checkout -b oldheader b4f292b4dbfad149697fb65c6a037bb3810813f9
make install PREFIX=/install/prefix`

AviSynth and AvxSynth are loaded dynamically. Distributors can build FFmpeg with `--enable-avisynth`, and the binaries will work regardless of the end user having AviSynth or AvxSynth installed - they’ll only need to be installed to use AviSynth scripts (obviously).

### 1.14 Intel QuickSync Video# TOC

FFmpeg can use Intel QuickSync Video (QSV) for accelerated encoding and decoding of multiple codecs. To use QSV, FFmpeg must be linked against the `libmfx` dispatcher, which loads the actual decoding libraries.

The dispatcher is open source and can be downloaded from https://github.com/lu-zero/mfx_dispatch.git. FFmpeg needs to be configured with the `--enable-libmfx` option and `pkg-config` needs to be able to locate the dispatcher’s `.pc` files.
