microphone

I am trying use a feature policy, serial, in my google add-on. I am having difficulty trying to enable this particular feature policy inside an iframe, mainly I believe is because the parent iframes don't have it enabled. Below is what the iframe DOM tree looks like. I don't have access to "sandboxFrame" and "userHtmlFrame" directly, so I cannot change its allowed features. Even if I set 'serial' in the most child iframe, I cannot find the 'serial' feature enabled in its featurePolicy.

I have a text input field in my recreation of the Google homepage. I'm using a flexbox for everything on the line with the search field, and I'm trying to give the search bar a minimum width and a maximum width when resizing the page, but I cannot for the life of me make it responsive—it always defaults to the min- or max-width and stays that way regardless of how narrow the window is.

Here's the search bar part of my HTML:

i am building an ecommerce website and i'm trying to add category button on the home page so that when you click a specific category, only those items will show. I am using redux to bring all the items to the home screen.

The iframe with allow="geolocation" works great. But what if I want to load a link which calls getCurrentPosition() from a html anchor tag?

Example : In iframe, I'll use

I have a use case where a html embed link like

Click here to get geolocation

is embedded in a parent site. The parent site loads the child link inside it's own iframe

It is to be noted that The parent site's iframe has the allow="geolocation" attribute .

In this case the request is silently denied with error

errorCode :1

errorMessage: "Geolocation has been disabled in this document by permissions policy."

The feature policy document point to iframe but what about anchor tag embeds?

I understand that I can use a iframe instead of anchor tag embed but the parent site only allows anchor tag's.

PS - This is my first question here. Please assist.

Note :

1. I also tried a random shot by including allow="geolocation" for anchor tag, but it doesn't work.
2. This seems to work on Safari (which I'm assuming is because Safari hasn't yet implemented feature policy for cross origin site requests)

Edit 1 :

I tried my use case in jsfiddle and notice that all scripts i give (iframe or anchor tag) are loaded inside jsfiddle's iframe

If i load my iframe inside this, it works perfectly !(perfectly balanced, as all things should be...)

But if I load my anchor tag inside this, i get the error. As per granty's answer

the jsfiddle's iframe with allow='geolocation' should set jsfiddle site's feature policy that all scripts loaded inside that iframe can access geolocation right ? Why does my iframe inside jsfiddle's iframe work but anchor tag doesnt ?

Note - I have no control over the top level site. I only code the scripts for https://siteWhichCallsGetGeolocation.com

SOLUTION (if you have control over top document's feature policy or control over any intermediate </code> which have geolocation permission)</strong> (derived from granty's answer)</p> <p>I tried the suggested solution by changing the jsfiddle's iframe attribute via inspect element to</p> <p><code><iframe name="result" allow="midi; geolocation https://siteWhichCallsGetGeolocation.com ; microphone; camera; display-capture; encrypted-media;" sandbox="allow-modals allow-forms allow-scripts allow-same-origin allow-popups allow-top-navigation-by-user-activation allow-downloads" allowfullscreen="" allowpaymentrequest="" frameborder="0">

I made a very simple arabic speech recognition program and attempted to make an exe of it using Pyinstaller. The exe file is succcesfully generated, but when I run it It does not recognize the speech, while, when I run the program from the IDE (Pycharm) It works fin an recognize the speech as expected. Here is my code:

I am streaming audio using FFMPeg and need to mix two audio sources using FFMpeg and set the volume level dynamically. I.e. once the stream starts, I need to be able update the ratio of the two volumes.

Currently, I have the volume mixing and streaming working using the CLI version of FFMPeg but the volume mix ratio is static.

Is there a way to dynamically set the volume ratio using the CLI tool? Perhaps something with an FFMpeg expression?

Or is using the API the only option? If so, can anyone point me towards an example of dynamically mixing audio? I haven't been able to find one.

Edit: here are the params I currently pass to mix audio. Again, this works fine, so not including the log as there is no error to fix. The question is how can I adjust the ratio of the amix mix after the process has launched. Willing to use the API if need be.

I'm facing this trouble with popup. When I select "get audio from desktop" and click "Start Recording" , another popup of browser appears , asking me for another decision ( It is about selecting the screen and sharing audio .I realize if I select "Sharing Audio" and click the blue button "share" . It starts to record and a modal appears : "website is sharing the screen and audio " but If I stop the recording with clicking "Stop Capture" button , the modal of "Website is sharing ... " still appearing . Could someone help me or explaining me if that is possible to disappear that modal when I click "Stop Capture" . Thanks.

I leave the codepen link, the design is a bit disorder but It has the code about the functionality, thanks.

I made a Discord bot for sending a message when someone joins a specific channel, but it also sends a message when the user mutes their microphone. What's wrong?

You can find my current code below:

I am developing a 3D environment that connects two microphones with a specific geometry in my scene , runs locally. I want to be able to switch between which microphone is being used ( when I press key A use mic1 and when I press key B use mic 2 ). The error I get is : Firefox ----> Error:NotReadableError: Concurrent mic process limit. Chrome -> no Error, it just doesn't switch devices

How can I fix that ? I tried to stop the stream but maybe I am not doing it right , any suggestions ?
