I have queries given below :
1)I want to know that, is it possible to implement web video chat(just like facebook, start video chat after installing some skype plugin)in java+jmf and server will be accessed via URL and different client can chat each other after installing some required plugin.
2)Is there any protype so i can start my exploration. Please share some implementation of video chat in jmf.
I decided to pass my opinion on this thread in stead of your more recent related one.
JMF is a dead, unsupported product. I would look for other solutions. A google for "Java jmf alternatives" is a good start. Note that doing a video chat is quite advanced material with many challenges to overcome and requires a big chunk of theoretical and practical knowledge on networking and audio/video compression if you want to be successful.
