Note:
-
The pluginspage is the relative URL of DynamicWebcam.msi for download. It only works for Firefox. For Chrome, Opera and Safari, etc., when the plug-in is not installed, you can show a download link on your page for the users to download DynamicWebcam.msi. For more info, please refer to the sample code installed with Dynamic Webcam SDK.
-
You must include the type attribute to specify the MIME type "Application/DynamicWebcam-Plugin" in an embed tag. If you do not, then there is no way for the browser to determine the media type and which plug-in to load.
-
After DynamicWebcam.msi is downloaded, you need to run it to install the plug-in.
