    Bonjour,
    Ok, that's pretty much all the French I know. I'm not sure that I understand why you're posting in French for help in Java for a camera located in Texas but...

    A short Google search lead me to this library. This camera pushes out a "mjpg" stream.

    Bonne chance

    Thank you, Sir, on your interaction with the subject
    I found this code, but it unfortunately only displays an image and does not display video
    I hope everyone help me, I am in desperate need of help
