有没有一种简单的方法可以通过PHP将非公共IP摄像机流式传输到网站？

Is there a simple way to stream a not public IP Camera into website with PHP?

I'm trying to embed a non public rtsp camera into a website without thirth part software or pluguins and capable for all browsers and devices, but I'm not able to do it.

I found a workaround that works but it is not elegant. It consists in take continuosly a snapshot of the camera from jpeg url camera acces and copy to a file with a runing php script on server:

 <?php
 while (True) {
    copy('http://192.168.x.x/snap.jpg?JpegSize=M&JpegCam=1', './webcam/frame.jpg'); // local URL from my camera to obtain jpg snapshot
    usleep (150000); // microseconds!!
 }
 ?>

Then, on client browser, this served page contain a javascript function that is responsible to refresh this snapshot and produce a webcam efect:

<script>
function reloadWebcam() {
   var now = new Date();
   document.images['webcam'].src = './webcam/frame.jpg?' + now.getTime();
}
</script>

...

<img name="webcam" align="center" width="640" height="480" scrolling="no">
<script>
setInterval('reloadWebcam()', 300); // 300 miliseconds
</script>

So, it works but I'm looking for:

a) an easy also solution but more elegant than this.

b) an improvement to this solution with a way to avoid subprocess of copy on server and/or avoid javascript refresh in client browser.
