QUESTION
I'm programming a web application that uses webrtc and the build in screen capture api of Chrome with getDisplayMedia.
In Chrome Browser i am experiencing a strange behaviour when sharing a non fullscreen window. The window is cropped by about 7 pixels on the left and bottom side in the captured stream. I noticed this effect when sharing a Mircosoft Excel Window (that is not in fullscreen), as there are plenty elements that are close the the window border. When i maximize the window it is not cropped in the stream.
I'm using Google Chrome Version 89.0.4389.128 (64-bit) and a standard 1080p monitor on Windows 10.
I've been able to replicate this issue in the getDiplayMedia demo of webrtc experiments, too. I didn't find an open bug report for Chrome for this issue. Did i miss something? Am i doing something wrong?
Any help or info would be highly appreciated.

QUESTION
I use Firebase Hosting and would like to realize this web app. (I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )
- push buttons and record audio (index.html + main.js)
- upload the audio file to Cloud Storage (main.js)
- transcribe the audio file using Cloud Speech to text API (index.js: cloud function)
- write the transcription on Cloud Firestore (index.js: cloud function)
- get transcription data from Firestore using
.onSnapshot. put that data in a textarea (main.js)
I passed step 1~4, but have a difficult in step 5. When I access the web app, it shows transcription data before I record audio.
This data was made the last time I accessed the web app.
When I go through step1 to step5, I get another textarea which is what I want. Could you tell me how can I avoid the first textarea? Thank you in advance.
This is browser's console.
This is main.js(client side)

Answered 2020-May-27 at 13:03This is because, as explained in the doc, when you set a listener, there is always an initial call.
In your case, this initial call returns the last document that was created in your collection (because your query is defined with orderBy("timestamp", "desc").limit(1)).
You could maintain a counter that indicates if it is the initial call or a subsequent one. Something along the following lines:
QUESTION
I make a simple audio recording web app using Firebase Hosting. I would like to record audio on browser and upload it to Cloud Storage. When I deploy and access my app, I can record audio. However the app failed to upload the audio to Cloud Storage.
(I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )
This is an error message in browser's console.
...ANSWER
Answered 2020-May-21 at 11:58I don't know much about the .wav file but you seem to be trying to store an object instead of a blob or a file that Firebase Storage is expecting. Try creating a var blob = recordAudio.getBlob() and replace file in your put() function with blob instead.

Answered 2020-May-21 at 05:59For you to get the permissions correctly, you need to check your Firebase Storage Security Rules. Configuring them correctly, will provide the access and permissions needed for the audios to be upload to the storage. By default, the rules will ask you to be authenticated, so you need to check to confirm. This way, you can either change your application to have authentication (best option) or the rules.
You can change the rules by accessing the Firebase Console and accessing the tab Rules. If you check the rules and they are similar or equal to the one below, it's confirming that you will need to be authenticated to write in the database, which is causing the error you are seeing.
QUESTION
I am working on an application using getDisplayMedia. When the browser prompts me to share my screen/a window and I select a specific window to share, that window is now suddenly focused and in front of my other windows (in particular, in front of the browser window!). I tested this with Firefox and Chrome, each on Ubuntu and Windows 10. I used this page to test.
I personally find this behavior kind of unexpected and annoying. I also fear that the technically less-inclined users of my application get very confused by this. So I'd like the browser to stay focused even after selecting a window. Is it possible to change that behavior? I checked the MDN docs on getDisplayMedia but did not find anything regarding this. I also did not find any information about this elsewhere.
If it's not possible to adjust that behavior, I'd like to know: why? Is it a technical limitation? Is it a privacy/security feature to make it more clear to the user that this window is shared now? (Personally I don't really think it helps the user but OK.)
...ANSWER
Answered 2020-Apr-22 at 19:18No, it is generally not possible to change this behavior, since it is intentional.
While this behavior is not mandated by any specification, most browsers today will push a just-shared window to front.
The rationale is the typical use case is someone presenting a document in a web conference call. In that context, the assumption is that since this is a user-initiated action (it requires a user gesture), the user intends to interact with the surface that they just shared.
In the past, browsers used to not do this, and users got confused about what was happening and about which window was being shared.
If you have a compelling use case where this is problematic, consider describing it in a new issue on the specification.
