Example Video stream with dmp
Answer
2/28/12 7:35 PM
I have been pulling my hair out trying to get a video stream to work with VLC and the DMP4400.   Can someone give me a example settings for a video transcode stream. 
I have tried all manner of RTSP stream in many different formats all using MPEG TS as the wrapper. 
I have attempted to do some differnt UDP or RTP multicast but not sure exactly how to set that up. 
Ii can succesfully join the RTSP stream with a different VLC client, just not with the DMP.   If i did not give enough information let me know, i can provide more.
 
start isma ipaddress /tt sigma 0 554
<table class="netInfoParamsText netInfoText netInfoParamsTable " style="width: 1px; height: 14px;" border="0" cellspacing="0" cellpadding="0">
<tbody class=" ">
<tr class=" ">
<td class="netInfoParamName "></td>
<td></td>
</tr>

The DMP does not support RTSP. You should output a UDP multicast, MPEG-TS wrapper. The codec inside should be either MEPG2 or h264.

Use some transcoding software and get your video file into MPEG TS format and saved to a file.
Then you can use this to stream it using VLC
c:\multicast\A1-v2.mpg if the path-filename of the video already transcoded and saved as MPEG TS.
Rest of the item should be easy to figure out.

"C:\Program Files\VideoLAN\VLC\vlc" -vvv c:\multicast\A1-v2.mpg --sout udp:239.192.100.100:1234 --ttl 3 --loop

Hope that helps

While the DMP can stream RTSP I don't think you'll be able to use VLC for the RTSP server.  VLC currently doesn't support interleaved RTSP which the DMP is requesting. Below is a capture of the conversation between the DMP (bolded) and a VLC server for RTSP.  Other stremaing servers do support interleaved.

You can try this for RTSP streaming from VLC.
The stuff I listed above is a simple UDP/Multicast.

Haven't played yet with SDP and RTSP.
Please let us know if you tried it and the results.
