The media property of each document specifies an object that contains multimedia properties and methods that apply to the document.
Note:The Doc.media is part of the Acrobat 6.0 (and Later) Compatible Media JavaScript API. Multimedia assets that use this approach rely on the underlying operating system to locate and launch a multimedia player residing on the user’s system. Acrobat 9.0 (and Later) natively supports Flash video (FLV) and Flash applications (SWF) which can be embedded in, or streamed to, a PDF document. Native support for Flash enables reliable cross-platform playback. No additional media player or specific codec is necessary.
Acrobat 6.0 (and Later) Compatible Media is superseded by the multimedia of Acrobat 9.0 (and Later), which uses rich media annotations. Developers of PDFs with multimedia assets are, therefore, strongly encouraged to use the rich media annotations of Acrobat 9 (and Later). Refer to the AnnotRichMedia object for JavaScript support for rich media annotations.
