Hi @ramiHedfi,

Can you please upgrade to 0.3.11 (you are using 0.3.10-RC6) to verify if this issue persist in the newest version and provide some code sample to reproduce it?

[sarxos]

Hi @ramiHedfi, any progress with this? Does issue persist after you upgraded to 0.3.11?

Hello sarxos,

Thank you for you quick reply :) and sorry for the delayed response.

I tried to upgrade to to 0.3.12 (0.3.11 I didn't found it). I get this error :-1:

Here is my source code :+1: source-code.txt

Thank you in advance

These are not errors. As you can see all these are at INFO level and error are on ERROR level.

Your code so soooo messy and you are doing many unnecessary things. Here is your code fixed:

    static {
        Webcam.setDriver(new IpCamDriver());
    }

    public ByteBuffer SaveImages(String CamIP, String idLane) throws MalformedURLException, InterruptedException, IOException {

        IpCamDeviceRegistry.register(CAMIPP, "http://" + CAMIPP + ":9901/video.mjpeg", IpCamMode.PUSH);
