I created a pdf 'landing page' into which I streamed wmv and flv video clips. The pdf was created from an InDesign document and I set the export to pdf for Reader v6.0 and above. The flv files were converted from avi using Media Encoder CS4 and the link to the server was inserted using the video tool on the mutlimedia toolbar of Acrobat 9.0 Pro.
I uploaded the document to the web but when viewers with Reader 7 installed on their machines click on the link it doesn't play and tells them they need to install Reader 9.2. When they do that it's OK but not everyone has admin rights and I need it to be playable in older versions of Reader. What am I doing wrong? How can I make it backwards compatible? Many thanks for any suggestions.
This change was deemed necessary as legacy multimedia opens an embedded window from a client application (Quicktime, Windows Media Player, etc.) on the client machine, and it is not possible to guarantee these external applications respect the Acrobat security sandbox model. It is therefore important that viewers know the PDF is free from any malicious intent before allowing playback, and we strongly recommend that users forced to retain earlier versions of Adobe Reader or Adobe Acrobat disable legacy multimedia in any non-trusted document.
Non-legacy multimedia embedded with the Acrobat 9 video/audio tools relies on the internal Flash Player, and so can be displayed securely without requiring the PDF to be trusted by the user. Malicious code in the Flash content stream is filtered out by the internal player.
