Audio and video conferencing using php

Is there a way to do Audio and video conferencing using php?
Is there ant open source tool through which I can do Audio and video conferencing using php from my Web site?

 

No. PHP is server side scripting. PHP itself cannot read webcams, etc. You'll need something else in addition to it. (and it's not going to run on shared hosting most likely, 99.9999% of the time)

 

I am trying to implement online class for student they will login on my web site and can listen and see the teacher taken classes at remote location. This my requirement is it possible in PHP wen site.

 

You want a ONE WAY stream from teacher (fixed stream) to student (at home)?

 

YES exactly you got my idea

 

It makes it much easier then.. is this going to be live stream or recorded?

 

Live Stream only no recording required. Once class is over story ends. Again user login for next session as per schedule.

 

Does this absolutely have to be self hosted, or can you just utilise a service like justin.tv?

 

See there will be security issues because students has to pay online for classes then they will get login authorization. I don't know about justin.tv
Can you give me some idea how it can work with my web site and user logged in my site.

 

Can you take a look at

and guide me will this fulfill my requirement

 

PHP is not a good language/platform for this.

You need an asynchronous language like Java or Flash for something like this. PHP is synchronous, which basically means "send request" -> "receive request" -> stop. Obviously video doesn't work like this, and a video conference especially doesn't work like this.

 

If doing so with php you'd possibly need this installed -> http://ffmpeg-php.sourceforge.net/

 

PHP has all the asynchronous capabilities of Java; just use socket_select(). Flash is sort of orthogonal to the question.

The bigger issue is that of re-inventing the wheel. Streaming is complicated and there are already a million solutions out there, VLC (www.videolan.org) for example. PHP could be used for the gatekeeping and control functionality.
