Re: Camera->VLC->DSS

if you are not willing to read it I cant help you. This did cost me two minutes or less:

(1) MPEG4(RTP) reproduction function
-- Reproduced MPEG-4 Video and G726 Audio of the RTP unicast and the multicast
PC communicates with the camera by the one to one. Because UDP is used compared with HTTP(TCP),
the delay is small.
Controlled session by RTSP.
Communicated two RTP stream of RTP(MPEG-4) and RTP(G.726).
The stream can be received by all clients that receive the multicast by a throw of the packet
at the multicast address from the camera.
Because all clients can be received by one stream, the band is made, and it is condensable,
and can make the reception potential client unrestricted in fact.


3. Method of Video Streaming and Communication flow
3.1 RTP unicast
PC is connected with the camera with peer-to-peer.
RTSP is used for the control of the connection.
RTP/UDP is used for the transmission of data.
RTCP is used for the control of data.
General knowledge concerning RTSP, RTP, RTCP, and SDP is needed.
Communication flow:
(1)It connects it with the RTSP server of the camera. Panasonic Communications Co., Ltd. - 103 -
(2)The DESCRIBE method is issued, and SDP is acquired.
(3)The SETUP method is issued.
(4)The PLAY method is issued.
(5)It receives the data, and it play back.
(6)The TEARDOWNmethod is issued.
(7) The connection is closed.
(1)It connects it with the RTSP server of the camera.
The socket is opened, and it connects it with the RTSP server of the camera
with TCP. The RTSP server is initial value 554.
(2)The DESCRIBE method is issued, and SDP is acquired.

Thats an SDP file, if I were you I would start with
