    rpm -Uvh --nodeps mpeg4ip_for_lmlm4-xxx.xxx-xxx.i386.rpm

    Actually, it will install both  server and  client on your computer. 
    Or compile it from source(servers_install.sh) on another linux distribution.

1.10 In Transmission Settings choose SDP file location, it's name 
     and generate it.
    
    
1.11 Deliver your SDP filname.sdp to client machine (by e-mail,ftp or web server).

1.12 On client machine install (rpm -Uvh --nodeps ...) 
     mpeg4ip_for_lmlm4-xxx.xxx-xxx.i386.rpm (for RedHat 9.0) 
     or compile it from source(servers_install.sh) on another linux 
     distribution.
    
    
1.13 On client machine launch:
     gmp4player filename.sdp
    
    
    
1.14. How to configure Mozilla to use gmp4player:

	1. Start Mozilla.
	2. Goto "Edit", "Preferences".
	3. Click on "Navigator", then on "Helper Applications".
	4. Click on "New type" button. It will open "New type" dialog window.
	5. Type :
		"video/lml" into "Description of type" field     
    		"sdp" into "File Extention" field
		"video/lml" into "MIME Type" field
		Find the path to gmp4player application ( most likely it will
                be in /usr/local/bin directory) and put it into "Application
		to use" filed and use "Choose" button.
	6. Click "OK" button.
	7. Click on "Downloads" under "Navigator" and select 
	   "Don't open anything".
	8. In Mozilla, connect to server machine : http://www.your.server.name
	9. Click on "Motion Video" link, then on "Video Stream channel1".
	10. It will bring gmp4player and the window with your stream on 
	your screen.
	11. If you close gmp4player  and start it again, you'll be 
	connected to the same port on the server machine.

NOTES:

PREVIEW ON MP4LIVE SERVER DISPLAYS ONLY I-FRAMES.
(speed factor)

If you changed LMLM4 card settings you must regenerate SDP file.

If you can't receive packets from server check your firewall rules.
(try /sbin/iptables -F command)

If your client falls restart it.

Look for your firewall setting on client machine 
if you can't receive video. 
try for example: 
$su - 
#service iptables stop



********  STREAMING FILE SAMPLES FROM LMLM4 CARD WITH DARWIN   ***********

Install mpeg4ip project and enter superuser mode (#su) 

2.1 Capture stream from LMLM4 using "lmlm4capture" program or by using (#cat or #dd)
   
2.2 If you've been captured stream using (#cat or #dd) 
    convert stream using "m4toavi" program to AVI stream
      
2.3 Convert LMLM4 AVI stream to streamable hinted stream :  
    "lmlM4convertor.sh FILENAME.avi FILENAME.mp4"
    where FILENAME.avi is avi stream you've been captured.

2.4 launch streamingadminserver.pl and your Internet browser (mozilla recommended)
	      
2.5 in browser follow URL: http://myserver.my:1220
    where myserver.my your server machine
				 
2.6 choose in "General settings" PATH to your media files(*.mp4).
		    
2.7 put your *.mp4 files in this media folder.

2.8 And press "Start Server" button if it's not started yet.
				       
2.8 now you can connect to server using "gmp4player" program as a client :
    
    gmp4player rtsp://myserver.my/FILENAME.mp4 (for Linux or for Windows)
    
    where FILENAME.mp4 is you mp4 file on server.


NOTES:
dont forget to open 554 port on your server's firewall :
for example for RH90 add:
"-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 554 --syn -j ACCEPT"
to /etc/sysconfig/iptables file.
