Thanks for the help Paul!
Your script auto updates the image correct. The only problem with this option is the refresh rate.
Because the original script still has to connect with the video server for each image, the refresh rate is limited by this.
The stream delivered by the ipsever is a continues stream of jpeg's as can be seen below (this is the raw data i need to process)

To be able to get a higher refresh rate, the original readstream_test.php script has to read a image, and continue to read the next image while proccessing the first image...
If you need the readstream_test.php script please let me know...
