A DMP4400G Might Not Output Audio After Finishing the Playback of a WMV File
After a DMP 4400G renders a Windows Media video asset for playback, you might find that subsequent
assets play without any audible sound (CSCtb09480). Our testing suggests that this behavior can occur
only when encoding of the WMV asset’s audio track has combined lossy compression with the
followingattributes.
•
Format: WMA
•
Codec ID: 162
•
Codec Info: Windows Media Audio 3
Tip You can use free or open source software—such as MediaInfo ( see http://mediainfo.sourceforge.net/en)— to check
if the audio track is encoded like this. If so, you can use other tools to re-encode or transcode the audio properly for playback.
Component Signal Cables Prevent DMP4310G Playback of 1080p60 Video
When a Component Video signal cable connects your DMP 4310G to its presentation system, the DMP
cannot render 1080p60 (progressive-scan) video for playback (CSCtf01345). However, the DMP4310G
in this case can render 1080i60 (interlaced-scan) video correctly.
SDP Support and Restrictions
We support ECDS live streams for digital signage, through the use of SDP files. However, our support
for SDP is limited.
•
We can play MPEG-TS/RTP/UDP multicast streams over Cisco ECDS networks when the multicast
host is a Cisco MDE 1100.
•
Alternatively, we can play other MPEG-TS/RTP/UDP multicast streams whose protocol is HTTP.
•
The SDP file must be generated by Cisco ECDS.
We do not support SDP optional values e, k, p, r, u, or z. Nor do we support SAP.
Note When you tell DMM the location of an SDP file on an ECDS server, you must enter the ECDS Delivery Service “Service
Routing Domain Name.” Do not enter the real host FQDN or the real host IPadd ress.
Also, you must specify the TCPport.
