\title Qt WebEngine Platform Notes
\brief Contains information about issues that are specific to the Qt WebEngine module.
\section1 Building Qt WebEngine from Source
The requirements for building Qt 5 modules from source are listed separately for each supported
platform:
\list
\li \l{Qt for Windows - Requirements}
\li \l{Qt for X11 Requirements}
\li \l{Qt for OS X - Requirements}
\endlist
In addition, the following tools are required for building the \l {Qt WebEngine} module:
\list
\li Windows: Visual Studio 2013 or Visual Studio 2015
\li Linux: Clang or GCC version 4.7 or later
\li OS X: Xcode version 5.1 or later
\endlist
\section1 Pepper Plugin API Support
Qt WebEngine supports loading Pepper Plugin API (PPAPI) plugins. The plugins must be loaded
manually using the Chromium command line syntax with the \c --register-pepper-plugins argument.
The argument value is a list of entries, separated by commas, that contain the file path and
one or several MIME types, separated by semicolons:
\code
<file-path-plugin1>;<mime-type-plugin1>,<file-path-plugin2>;<mime-type1-plugin2>;<mime-type2-plugin2>
\endcode
For example:
\code
--register-pepper-plugins="libppapi_example.so;application/x-ppapi-example"
\endcode
The MIME type is important because it determines which embeds the plugin is used for.
This process has been automated for the Adobe Flash Player Plugin.
\section2 Adobe Flash Player Plugin Support
The Adobe Flash player plugin can be loaded automatically if it is installed in one of the
following locations, depending on the platform:
\list
\li Windows
\code
C:\Windows\SysWOW64\Macromed\Flash\pepflashplayer*.dll
C:\Windows\System32\Macromed\Flash\pepflashplayer*.dll
\endcode
\li OS X
\code
/Library/Internet Plug-Ins/PepperFlashPlayer/PepperFlashPlayer.plugin
\endcode
\li Linux
\code
/usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so
/usr/lib/PepperFlash/libpepflashplayer.so
/usr/lib64/chromium/PepperFlash/libpepflashplayer.so
\endcode
\endlist
You can also load the Flash player from a specific location by using command line arguments:
\code
--ppapi-flash-path=./libpepflashplayer.so
\endcode
\section1 Audio and Video Codec Support
Qt WebEngine supports the MPEG-4 Part 14 (MP4) file format only if the required proprietary
audio and video codecs, such as H.264 and MPEG layer-3 (MP3), have been enabled. Proprietary
codecs can be enabled by passing the following option to qmake:
\code
qmake WEBENGINE_CONFIG += use_proprietary_codecs
\endcode
\warning When distributing proprietary codec libraries, you must acquire licenses for them.
\l FFmpeg is a cross-platform solution to record, convert, and stream audio and video. It can
be configured for use with several codecs, which rises licensing issues during distribution
with the codec libraries. For some codecs, open source implementations, such as \l {OpenH264},
are available.
