    I am currently working on a screen capturing feature in chrome using

    navigator.mediaDevices.getDisplayMedia

    I am only able to open a user selection where the user can choose from all the given displaymedias. Is there any way to go around the selection and select a tab via the tab name automaticly?

    I have read the privacy and security part in which it says that

    In addition, user permission is always required to access the user's audio and video inputs.

    but im still wondering if there is a way?

    Reset to default 15

    very few available constrains for getDisplayMedia

    getDisplayMedia({preferCurrentTab:true}) // in chrome 96

    hopefully getViewportMedia, getViewportScreenshot ing soon

    Try this mand-line flag:

    --auto-select-tab-capture-source-by-title="The target tab's title"
