Java Media Framework vs IP Camera JPEG/MJPEG

+ This article is pretty deprecated. I do not say that the info here is false, but I would like to write a new article about this. Please leave me comments with what you want to know, and I will try do add more info to the article. And ofcourse, more sources.

I really don”t think I”m either the first or the last to try and obtain images from and ip camera and than use them with JMF. So… after a few days of reading and trying to understand how JMF works, as I already had a JPEG/MJPEG grabber, here is my solutions:

As Chris Adamson explains in his article, Java Media Development with QuickTime for Java, to create a new JMF plugin you need to create two classes, one to extend DataSource and one to extend PushBufferStream or PullBufferStream from JMF.

I”m sure it won”t take long to you to understant that the protocol is just a simple name, and can be easily changed in my example:

    I’ve decided to rewrite this article, but for now I do not have too much time for it. (I left this problem about an year ago, and I don’t work any more with JMF) If there is anyone interested in helping me it would be great.

    Here are some old hints I wrote on the SUN forum on that time:
