Unable to open input rtsp Due to Operation in Progress

Good day i have installed zoneminder 1.28.1 on my centos 6.6 64 bit version but when i am adding some of my camera (Axis M3204 Network Camera and Axis M3203 Network Camera) and i get a blue screen and not recording with the error message on the logs:

but some of our cameras (same camera model) do not experiencing with this problem.

That means something else has got a lock on that video stream.
Make sure you don't have the cameras web page open.
It is possible that your previous attempt to connect in zoneminder still has the lock (especially if that previous attempt was abnormally stopped).

Make sure nothing else is accessing that camera, reboot the camera, and try again.

Also, make sure you are running latest camera firmware.

All camera firmware is all up to date also no one accessing to the camera. The only thing that i am confused is i can add the camera on other zoneminder machine that i installed last year and now on my new zoneminder machine i had with this trouble. can you help me to fix this one.

thankyou

Hi toygwapo005,

Are you using Ffmpeg or Libvlc? I had the same problem with ZM1.28.1 and Ffmpeg in one of my cameras. Just switched to Libvlc and the problem dissapeared.

Hope it helps,

PacoLM

You will need to add the port you are using to the source string:

rtsp://192.168.xx.xxx:554/axis-media/media.amp?streamprofile=Balanced?tcp

Not sure what port your camera uses for RTSP. I have a Foscam that I have set to port 80 vs. 554
