Concepts
Shockwave Flash (SWF) Support and Restrictions
Note This release does not support audio in Shockwave Flash media. If your media library contains any Shockwave Flash files
that use audio, their playback will be silent.
•
The filename extension must be SWF and you must enter the estimated duration.
•
On a DMP 4305G, avoid playing MP3 audio at the same time as a SWF. Otherwise, the SWF plays
approximately 50 percent slower than it should. The cause is a hardware limitation. (CSCty77918;
CSCtg15314)
•
When a SWF asset has a memory leak that depletes DMP memory, the DMP will not necessarily
reboot automatically, as it is designed to do in some other low-memory scenarios. Instead, if you
have enabled DMP failover (content substitution) and if the alternative content is loadable, your
DMP will load it. But if this attempt fails, your DMP will restart itself automatically, as it does in
those other low-memory scenarios. (CSCty84687; CSCtt29360; CSCtw90991)
MP3 Support and Restrictions
•
This release does not support DMP playback of any MP3 file that contains embedded cover art
(CSCtw78806).
•
This release does not support DMP 4305G playback of any MP3 file with a 24000 sample rate
(CSCtb79824).
•
On a DMP 4305G, avoid playing MP3 audio at the same time as a SWF. Otherwise, the SWF plays
approximately 50 percent slower than it should. The cause is a hardware limitation. (CSCty77918;
CSCtg15314)
MPEG-4 Support and Restrictions
Our support for MPEG-4 requires that you use the MPEG-4 Part 2 or Part 10 (H.264) codec and that you
multiplex audio and video in an MPEG-2 Transport Stream.
•
When your DMP is a 4400G, we support MPEG-4 Part 10/H.264 video in MPEG-2 TS.
•
Neither the 4300G nor the 4305G supports MPEG-4 Part 10/H.264.
The filename extension must be MPG or MPEG and you must enter the estimated duration.
Bitmapped/Raster Image (JPG, GIF, PNG) Support and Restrictions
•
A DMP 4305G in this release does not support use of PNG images.
•
The maximum supported file size per bitmapped image asset is 450 KB on a DMP 4305G and 1 MB
on a DMP 4400G.
•
When your designs for digital signage call for an image with fixed dimensions, such as 640 x 480,
import a bitmap asset of exactly these dimensions. Do not import a larger or smaller version.
Otherwise, your DMP must resize the wrong-sized bitmap on-the-fly for rendering. This work is
computationally expensive, and degrades DMP performance over time. (CSCtx99460;
