  91. <h1 class="chapter"><a href="general.html#toc-External-libraries">1 External libraries</a></h1>

  92. 

  93. <p>FFmpeg can be hooked up with a number of external libraries to add support

  94. for more formats. None of them are used by default, their use has to be

  95. explicitly requested by passing the appropriate flags to

  96. <code>./configure</code>.

  97. </p>

  98. <a name="Alliance-for-Open-Media-_0028AOM_0029"></a>

  99. <h2 class="section"><a href="general.html#toc-Alliance-for-Open-Media-_0028AOM_0029">1.1 Alliance for Open Media (AOM)</a></h2>

  100. 

  101. <p>FFmpeg can make use of the AOM library for AV1 decoding and encoding.

  102. </p>

  103. <p>Go to <a href="http://aomedia.org/">http://aomedia.org/</a> and follow the instructions for

  104. installing the library. Then pass <code>--enable-libaom</code> to configure to

  105. enable it.

  106. </p>

  107. <a name="AMD-AMF_002fVCE"></a>

  108. <h2 class="section"><a href="general.html#toc-AMD-AMF_002fVCE">1.2 AMD AMF/VCE</a></h2>

  109. 

  110. <p>FFmpeg can use the AMD Advanced Media Framework library

  111. for accelerated H.264 and HEVC(only windows) encoding on hardware with Video Coding Engine (VCE).

  112. </p>

  113. <p>To enable support you must obtain the AMF framework header files(version 1.4.9+) from

  114. <a href="https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git">https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git</a>.

  115. </p>

  116. <p>Create an <code>AMF/</code> directory in the system include path.

  117. Copy the contents of <code>AMF/amf/public/include/</code> into that directory.

  118. Then configure FFmpeg with <code>--enable-amf</code>.

  119. </p>

  120. <p>Initialization of amf encoder occurs in this order:

  121. 1) trying to initialize through dx11(only windows)

  122. 2) trying to initialize through dx9(only windows)

  123. 3) trying to initialize through vulkan

  124. </p>

  125. <p>To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and amf-amdgpu-pro

  126. package(amdgru-pro contains, but does not install automatically) are required.

  127. </p>

  128. <p>This driver can be installed using amdgpu-pro-install script in official amd driver archive.

  129. </p>

  130. <a name="AviSynth"></a>

  131. <h2 class="section"><a href="general.html#toc-AviSynth">1.3 AviSynth</a></h2>

  132. 

  133. <p>FFmpeg can read AviSynth scripts as input. To enable support, pass

  134. <code>--enable-avisynth</code> to configure.  The correct headers are

  135. included in compat/avisynth/, which allows the user to enable support

  136. without needing to search for these headers themselves.

  137. </p>

  138. <p>For Windows, supported AviSynth variants are

  139. <a href="http://avisynth.nl">AviSynth 2.6 RC1 or higher</a> for 32-bit builds and

  140. <a href="http://avisynth.nl/index.php/AviSynth+">AviSynth+ r1718 or higher</a> for 32-bit and 64-bit builds.

  141. </p>

  142. <p>For Linux and OS X, the supported AviSynth variant is

  143. <a href="https://github.com/avxsynth/avxsynth">AvxSynth</a>.

  144. </p>

  145. <div class="float alert alert-info">

  146. <p>In 2016, AviSynth+ added support for building with GCC. However, due to

  147. the eccentricities of Windows&rsquo; calling conventions, 32-bit GCC builds

  148. of AviSynth+ are not compatible with typical 32-bit builds of FFmpeg.

  149. </p>

  150. <p>By default, FFmpeg assumes compatibility with 32-bit MSVC builds of

  151. AviSynth+ since that is the most widely-used and entrenched build

  152. configuration.  Users can override this and enable support for 32-bit

  180. Once libcodec2 is installed you can pass <code>--enable-libcodec2</code> to configure to enable it.

  181. </p>

  182. <p>The easiest way to use codec2 is with .c2 files, since they contain the mode information required for decoding.

  183. To encode such a file, use a .c2 file extension and give the libcodec2 encoder the -mode option:

  184. <code>ffmpeg -i input.wav -mode 700C output.c2</code>.

  185. Playback is as simple as <code>ffplay output.c2</code>.

  186. For a list of supported modes, run <code>ffmpeg -h encoder=libcodec2</code>.

  187. Raw codec2 files are also supported.

  188. To make sense of them the mode in use needs to be specified as a format option:

  189. <code>ffmpeg -f codec2raw -mode 1300 -i input.raw output.wav</code>.
