<div>Dear Gurcharan, </div>
<div> </div>
<div>Yes, you can simply modify ExtendedVideoProducerService for on-demand content streaming. If one wants to deliver a video file on local host, one can change the executable parameters of VLC and put specific items such as the file name in ExtendedVideoProducerService. (refer to VLC command line interface: <a href="http://www.videolan.org/doc/vlc-user-guide/en/index.html">http://www.videolan.org/doc/vlc-user-guide/en/index.html</a>)</div>
<div> </div>
<div>I believe that this is a good way for providing cumstomizable video producer services.</div>
<div> </div>
<div>I additionally explain the way of session announcement of ExtendedVideo{Producer, Consumer}Services for live streaming in PS #1. If you need this, please refer to it.</div>
<div> </div>
<div>Best regards,</div>

<div>PS #1) To announce video stream (to be used in a Venue), ExtendedVideoProducerService uses a combination of SDP (session description protocol) and SAP (session announcement protocol). SDP message specify a multicast address for video delivery (to be assigned by a Venue) and a video fromat (e.g. DV or HDV). As parsing the SDP message, ExtendedVideoConsumerService understands the characteristics of the stream, which include the multicast address for video delivery and the video format.</div>

<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">hi,<br><br>i know that the AGDV extendedvideoservice can listen to a multicast stream<br>expecting a HDV format and that the producer generates such a stream.<br>
<br>i was wondering if the producer service could instead call for an rtsp stream for a video<br>on demand file to be sent to the venue. is this doable in the current code?<br><br>or are there better ways to inject streaming video into a Venue?<br>
