JMF and clinet side Applet problem
HI,
I need to create an Applets and applications that will transmits and receive media using RTP in [JMF]Java Compatible environment--including Web browsers--without having to worry about client side JMF installation.Will it be possible to deploy a java applet on a client browser without having the client
to install stuff ?
My Applet will run on client machine and need to capture and play audio and video using JMF.
My Applet also needs JMF classes so, i send jmf.jar file with my applet.
My Applet is also signed.
But doing all this step i am not able to get/capture device on client machine.
