+\title Qt Multimedia on WebAssembly
+\brief Platform notes for WebAssembly
+
+This page covers the availability of Qt Multimedia features on WebAssembly.
+
+\section1 Limitations
+
+Due to the asynchronous nature of javascript, some features such as getting the list of
+QMediaDevices, will not be readily available and may take some time to request permissions and
+gather the list of devices. The audioInputsChanged, audioOutputsChanged and
+videoInputChanged signals from QMediaDevices class will be emitted when they are available.
+
+Playing video currently works by using a html 2d context, so all operations are on the CPU.
+
+Performance is acceptable, although there is a copy on every frame, so it may be
+less performant than desktop platforms when playing hi-def video.
+
+Using and selecting different Codecs/video formats have not yet been tested, but whatever
+video formats the browser supports will most likely work.
+
+Playing data from a stream (using \c {setSourceDevice(QIODevice*)}), instead
+of fetching a URL, isn't supported.
+
+Some advanced features may or may not work at this time.
+
+Files can be served from the/any web server, respective
+of \l{https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS}{CORS}. Because of
+the limited size of local file storage, playing local files is discouraged.
