-===== Ziel: mjpeg auf dem Browser ===== +

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

-Webinterface ruft folgendes JavaScript auf: +

-<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">'); +

-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. +
