  • Open VideoStream using OpenCV 4.5.1 works on Windows but fails on Docker python:3.9.2-slim-buster for specific IP cam

    18 mai 2021, par Qua285

    I have 2 ip cameras - one of Hikvision and another of Provision ISR. Both use Onvif and work on VLC.
I've written a simple python script to record images every 5 sec from their video stream.
On Windows 10, using VSCode they both work as expected. Once deployed to a Docker container, my script works as expected with the Hikvision but fails with the Provision ISR - it doesn't open the stream.

    


    Running python -c "import cv2; print(cv2.getBuildInformation())" on windows (venv 3.9.2) and on docker machine bring slightly different results but it's beyond my understanding to take something out of it...
Here is the Windows one :

  • Evolution #4702 : Déplacer le bloc des stats_hits

    24 mars 2021, par cedric -

    Sur un grand écran il est actuellement plus à gauche que le bando, donc gêne pas du tout, il faudrait donc adapter en fonction de la taille écran sinon
    Il faut pas oublier qu’il est partout, aussi sur le public, et que le mettre en plein milieu va pas forcément être génial en plus de faire une collision avec les boutons d’admin

    Donc peut-être plutot dans le coin bas à gauche, car il gênera toujours moins ?

    I am trying to record and save a video with an ffmpeg app on android 10. I'm very new to android/mobile development.

    


    Here is my manifest file :

    


    &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<manifest package="com.example.camera">&#xA;    &#xA;    &#xA;    &#xA;&#xA;    &#xA;&#xA;&#xA;    &#xA;        <activity>&#xA;            &#xA;            &#xA;        </activity>        <activity>&#xA;            &#xA;                <action></action>&#xA;&#xA;                <category></category>&#xA;            &#xA;        </activity>&#xA;    &#xA;&#xA;&#xA;</manifest>&#xA;

    &#xA;

    As you can see, I am specifying permission to read/write data.

    &#xA;

    Here is my mainActivity :

    The error I'm particularity confused about is :

    &#xA;

    I thought I specified the appropriate permissions in the manifest file ? Please advise.
