I have the requirement to display two IP cameras at the same time. For this I used the demo \ImageAcquisition\CaptFromIPCamera. The method that processes IEGetFromURL is called via two PostMessages. The first camera shows the image and it is no longer updated. The second camera shows the stream.
Does anyone have an idea why both streams are not displayed?
I can't see anything wrong with the code. Did you try capturing from two different web sites in case the one you are using rejects the second connection?
yes exactly, I have two ip cameras in the LAN. If I only activate the left or the right one in the application, then I get the stream from the camera. As soon as I activate the second, the first stops. The Camers deliver 2M pixels. Processor load goes pretty high at around 80%. The cameras are from Axis. Axis has freeware to operate up to 16 cameras. With this software I was able to receive the same stream from both cameras. The processor load is around 50%.
[Edit] Another note: If I only activate one camera in the application and start the application twice, both streams work. Application1 shows the stream of Camera1 and Application2 shows the stream of Camera2. It doesn't work if both are in one application.
