Multimedia content

h2. Description
PDFs may contain multimedia content: movies, sound and 3D content.

h2. Risks
Rendering of multimedia content may depend on external applications that may not
be available in the future; the format in which multimedia content is stored may become obsolete.

h2. Assessment
The following table shows the relevant output of _Apache Preflight_ (part of [Apache PDFBox]) for PDFs that contain multimedia. Results obtained with _Preflight_ 2.0.0:

h3. Other multimedia annotations
_Screen_ and _Movie_ annotations are not the only multimedia annotations in PDF. The [format specification|http://wiki.opf-labs.org/download/attachments/22249545/PDF32000_2008.pdf?version=1&modificationDate=1359991314000] distinguishes the following multimedia annotations:

* _Movie_ annotations (predecessor of _Screen_ annotations, deprecated since PDF 1.5)
* _Screen_ annotations
* _Sound_ annotations
* _3D_ annotations (3D objects, since PDF 1.6)

So in general any profiling for audiovisual multimedia content should include _Movie_, _Screen_ and _Sound_ annotations (and/or their corresponding Actions).
