QUESTION
I am capturing user screen and audio using getDisplayMedia and getUserMedia and able to record the complete screen capture. But this works only on Chrome and not on Firefox. When I run my application on Firefox it throws error 'DOMException: AudioContext.createMediaStreamSource: No audio tracks in MediaStream'. Below is my code snippet. I have latest version of both browsers installed. Any help would be appreciated. Thanks in advance.
Note:- Its throwing error on line context.createMediaStreamSource(desktopStream)
...ANSWER
Answered 2021-Jun-08 at 10:59Firefox doesn't currently support capturing audio using getDisplayMedia. There's a feature request for it.
What you could do is check whether your streams have any audio tracks before creating the audio node, like this:
QUESTION
Answer/Solution: To be clear Jorn Vernee's answer is correct in that when i created my .h file originally i didnt have the package information in the .java class but when my code was executed it did have the package information. The method names in the .h file will end up including the package information in the name.
I've got some C++ code that i use to take a screen shot. I've been attempting to call it from Java using both JNA and JNI and having no luck with either. My ultimate goal is to get the captureScreen method working. I created a getNumber method just as a simple test with no parameters passed in but even it wouldnt work.
Update My application is running as a 64 bit application and my dll is 64 bit. Not sure if that affects the parameters passed in or out.
My current implementation

I am working on a project where I need the user to be able to record screen, audio and microphone. At the moment I could only make it recognize screen and audio.
First I am capturing the screen and the audio from it and saving it to a variable. And then I am capturing that variable to show the a video component.

QUESTION
I have a python code which detects faces, but if I am 3 meters away, it won't recognize me anymore... I am new to python and I think I can do more, if you can tell me the code I have to change.
Can somebody help me?
...ANSWER
Answered 2021-Apr-24 at 10:11I guess the problem is rather in the big distance and small face then in algorithm. face_recognition.face_locations() has an argument: number_of_times_to_upsample Try to set it 2 or more: as much as smaller faces to be found.
QUESTION
i am using the Desktop Duplication API - to take a screenshot (c++). This works in principle, but not under every resolution.
i am creating an opencv mat from the D3D11_MAPPED_SUBRESOURCE and then display the image.
Under 1920x1080 it looks like this (correct):
Under 1366x768 it looks like this (wrong) (while 1360x768 works correct): There are some other resolutions with the same effect.
Does anyone have an idea what this could be ?

QUESTION
In one of my previous questions I asked how I could take a screenshot of everything that's inside of a ScrollViewer, not just what's visible in the ViewPort. After a lot of trying I found myself an answer, but unfortunately this answer raises another question.
Have a look at this example code:
ItemViewModel.vb (just a simple view model for my TreeViewItems):
ANSWER
Answered 2020-Nov-19 at 02:05I am not that proficient with WPF, but creating a VisualBrush to draw the items seems wrong. So instead of the code using the VisualBrush and DrawingVisual, just use renderTarget.Render(source).
QUESTION
I'd like to take a screenshot of whatever is inside a ScrollViewer, not just what is seen inside the ViewPort. But everything I tried so far results in completely black images or in images where only parts of the content are shown and everything else is black. I assumed that it's maybe because I didn't specify any backgrounds, but changing the background of my Window or my TreeView to White didn't change a thing.
Can you tell me what is wrong or how else I can take a screenshot of the full content of a ScrollViewer?
Here's a little sample I put together (press 'P' after the main window is shown).
The main window (just a TreeView in a Window that is too small to show the full content):
ANSWER
Answered 2020-Nov-18 at 23:31After a lot of trial and error I found out, that I got several things wrong.
First, I used the wrong UIElement. I had to take the first StackPanel instead of the first ScrollViewer.
Second, although my Window has the background set to white, all my controls inside Window doesn't have a background, that's probably why my resulting picture is black.
So, changing just one function of my code to

In angular 9 how to open html content in new tab in pdf format. I already completed the code using jspdf. But it is working only for mozilla and IE. Chrome blocking new tab. So tried in another way using Iframe. Then it is working for chrome also. But in my html content more design code need to include. After that when I tried blank page is coming in new tab. My code is like this.
ngx-table-popup.component.html
View PDF Format
ngx-table-popup.component.ts
...ANSWER
Answered 2020-Oct-06 at 05:33To open a report in the new window you can use the window object.
.// Here you just need to convert pdf to base64 string.
const reportpdf = btoa(pdf.output());
// pass it into the createObjectURL method
if (reportpdf) {
const blobURL = URL.createObjectURL(this.pdfBlobConversion(reportpdf, 'application/pdf'));
window.open(blobURL);
}
// converts base64 to blob type for windows
pdfBlobConversion(b64Data: string, contentType: string) {
contentType = contentType || '';
const sliceSize = 512;
b64Data = b64Data.replace(/^[^,]+,/, '');
b64Data = b64Data.replace(/\s/g, '');
const byteCharacters = window.atob(b64Data);
const byteArrays = [];
for (let offset = 0; offset < byteCharacters.length; offset = offset + sliceSize) {
const slice = byteCharacters.slice(offset, offset + sliceSize);
const byteNumbers = new Array(slice.length);
for (let i = 0; i < slice.length; i++) {
byteNumbers[i] = slice.charCodeAt(i);
}
const byteArray = new Uint8Array(byteNumbers);
byteArrays.push(byteArray);
}
const blob = new Blob(byteArrays, { type: contentType });
return blob;
}
