kandi X-RAY | enumerateDevices Summary
####What This is a simple module for normalizing the differences in enumerating media devices in webkit (Chrome/Opera) and Mozilla (Firefox). ####Why Because the usages and results of the two implementations differ, and it's nice to normalize the behavior and results. Test by running npm start and visiting View a demo of the module in use on the test page.

QUESTION
I have created an application that sings along in the app with the web audio API of JavaScript. This worked perfectly on iOS safari and Chrome, but the sound quality was poor on Android Chrome. To solve this, I tried changing the audio deviceId, but it still didn't work. Does someone have information that might help?
Doubt: After recording, I pass the file to the server and play it on another page. I am wondering if this is causing the problem.
This is my code
...ANSWER
Answered 2021-May-25 at 19:58When trying to build high-quality audio with getDisplayMedia, in the past I've passed in MediaStreamConstraints that remove some of the default processing on the input track:
stream = await navigator.mediaDevices.getDisplayMedia({ video: true, audio: { channels: 2, autoGainControl: false, echoCancellation: false, noiseSuppression: false }});
I'm still learning WebRTC myself, so I'm not sure if these same properties can be passed when using getUserMedia and MediaConstraints, but I thought I'd share in case helpful. It sounds like this might also be about available devices. Good luck!
QUESTION
Banging my head to the wall with this one, I can't seem to understand what is holding on the camera video stream and not closing when MediaStreamTrack.stop() called.
I have a typescript class where I handle getting the WebRTC stream track and passing it using an observable event to a functional reactjs component, the below code is the component registering to the event and using state for the stream track.

videoStreamTrack?.stop()
videoElement.current.srcObject.getVideoTracks().forEach((track) => {
track.stop()
videoElement.current.srcObject.removeTrack(track)

videoElement.current.srcObject = null
}
}, [])

I have a problem with live video stream from 2 GigE cameras in QML. I tried it before with QLabels and QPixmap and it worked without any problem. The QML Labels don't have pixmap property to send images using signal slots.
Here is my Python code:

Using the following code to get all the available microphones and update a selector with that list.
...ANSWER
Answered 2021-Mar-03 at 11:54There is no "label" on an option and you need to return the option
QUESTION
I have the following code to fill up a select with the available microphones
ANSWER
Answered 2021-Mar-03 at 11:10getConnectedDevices is an async function, meaning that it returns a Promise instead of an array. You can use the .then function to update the list when the Promise is fulfilled.
QUESTION
Is there a way to detect which device (camera, microphone) is active, given a MediaStream instance?
The app I'm currently working on does simply query for such a stream and attaches it to a element:

QUESTION
I have this function that returns an observable that emits a deviceId and its related MediaStream:
...ANSWER
Answered 2021-Jan-31 at 13:25You cannot pass a number or a variable into take.
Also, once you use tap after a take(1), tap won't be active.
Another thing is that a tap is a side effect which means that you cannot propagate the assigned value inside a tap to an operator.
If you need a conditioned take, then you should use takeUntil or takeWhile.
Now, specifically for your question, you are using take the wrong way.
Here is zip definition: After all observables emit, emit values as an array.
That means that if all obervables have been emitted and you have the final emitted array, then you should be good with take(1) because the process is automatic.
There is no need to worry about the take(devicesCounter).
Also, if you do not care about the final result as an array, you could use forkJoin.
forkJoin is when all observables complete, emit the last emitted value from each.
It means that you already know that all of the observables are completed and therefore you can use take(1) with no worries right after the forkJoin.
To sum up, your current code works fine and you don't need to worry for irrelevant take(number)
QUESTION
I have a flask app that is supposed to record video and be able to send that video back to my python scripts to be then put into the database. I've tried to put it into a form but not too sure I'm doing it the right way. here is my js
...ANSWER
Answered 2021-Jan-13 at 02:20You can either use a form of the type "multipart/form-data" to transfer the video.
With this variant, the data can be accessed in flask as a file (werkzeug.FileStorage).
