===== Ziel: mjpeg auf dem Browser =====

Problem: Keine Dokumentation. Webinterface soll das zwar können, aber JAvaScript zu schlecht.

<del>Schaut gut aus, klappt aber nicht:

mplayer http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab -vo gl</del>


Webinterface ruft folgendes JavaScript auf:

http://gerald.webhop.org:14322/ipcam.js?v=200708241090
<code>document.write('<OBJECT ID="IPCam_Plugin" CLASSID=clsid:b015b944-7316-49ae-ac84-acca9379ea32 ALIGN="CENTER" WIDTH="'+ ipcam_width +'" HEIGHT="'+ ipcam_height +'" Codebase="/IPCamPluginMJPEG.cab#version=1,0,9,2">');
document.write('<PARAM name="IP" value="'+ window.location.hostname +'">');
document.write('<PARAM name="Port" value="'+ port +'">');
document.write('<PARAM name="Login" value="'+ login +'">');
document.write('<PARAM name="Password" value="'+ password +'">');
document.write('<PARAM name="Code" value="'+ code +'">');
document.write('<PARAM name="Debug" value="0">');
document.write('</OBJECT>');</code>

Das Plugin kann man mit <code>
wget http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab
</code> runterladen

Das Plugin ist von der Firma 'Edimax' und ist anscheinend für den IE geschrieben. Dort funktioniert es aber auch nicht richtig, der IE beschwert sich über Fehler auf den Seiten.

You can get images from your camera with my PHP script and a web server in the following form:

Vom Hersteller EdiMax gibt es auch die Software als OpenSource ((http://www.edimax.com/images/Image/OpenSourceCode/Wireless/IPCamera/IC-1500wg/IC1500_RTL865X.tar.gz))

Mit einer URL alle Parameter verstellen:
[[http://admin:1234@192.168.2.3/form/camera?resolution=0&quality=3&framerate=25&frequency=0&autoexposure=ON&b_value=35&c_value=50&s_value=50&h_value=50&w_value=10&enet_source=camera_left.asp]] 
 
Options are as follows: 
 
<code> Resolution: 
 0 = 640x480 
 1 = 320x240
 3 = 176x144
 
 Quality: 
 3 = Highest 
 = High
 = Normal
 = Low
 = Lowest
 
 Frame Rate: 
 30 = 30 frames per second (FPS) 
 25 = 25 FPS 
 20 = 20 FPS 
 15 = 15 FPS 
 10 = 10 FPS
 5 = 5 FPS 
 3 = 3 FPS
 1 = 1 FPS
 
 
 Frequency: 
 60 = 60Hz (this works best in the night or indoors in incandescent light)
 50 = 50 Hz (this is for fluorescent light or night)
 0 = "Outdoor" mode (this works best during the day)
 
 Auto Exposure: 
 ON /OFF 
 
 Others values are listed below, but the defaults have been noted to work fine.
 Black
 White
