Problem: Keine Dokumentation. Webinterface soll das zwar können, aber JAvaScript zu schlecht.
Schaut gut aus, klappt aber nicht:
mplayer http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab -vo gl
Webinterface ruft folgendes JavaScript auf:
http://gerald.webhop.org:14322/ipcam.js?v=200708241090
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>');
Das Plugin kann man mit
wget http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab
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: Quelle2)
<? $login = "admin"; $pass = "xxxxxxx"; $ip = "aa.bb.cc.dd"; $port = "4321"; // 120 byte // 3x 0x00, // 1x 0x01, // user name // 1x 0x00, // password, // Nx 0x00, $logincmd = pack( "x3H*a*xa*x" .

Vom Hersteller EdiMax gibt es auch die Software als OpenSource 3)
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:
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.
