QUESTION
I have multiple cameras in my Windows 11 system and I am wondering how to get all avaiable resolutions for them. I am not intending to make a video capture, but I am willing to just get these properties.
Also, I don't care which API to use, be it DirectShow or MMF (Microsoft Media Foundation). I haven't used any of these before either.
I have found multiple resources doing that in C# (as in here), but similar suggested answers for C++ are hard to understand - some code is given, but what libraries and 'includes' used is not given (as in here)
I have also checked DirectShow samples in hope something would be there, but I didn't find anything.
So, I checked MMF as well (1, 2, 3) and docs, but all posts seem pretty outdated and no full code is given showing how to use certain functions alongside proper 'includes', as trying the code gives me unresolved symbols.
So I am kind of stuck at the moment, I can't find a solution to this.
I would appreciate any help.

You generally do care because the data might be different.
With Media Foundation, see How to Set the Video Capture Format
Call IMFMediaTypeHandler::GetMediaTypeCount to get the number of supported formats.
You might also want to have a look at Tanta: Windows Media Foundation Sample Projects and sample code there.
With DirectShow, see Webcamera supported video formats in addition to links you found; you will have to sort out includes and libraries through, among SDK samples AMCap does some one this and can be built from source without additional external libraries, from original code or from this fork adopted to most recent VS.

I have a S3 bucket on AWS to which I am uploading images from the frontend.
After successfully uploading an image to S3, this is the URL I get -
https://cewa-foundation-2020.s3.amazonaws.com/image8_%281%29.webp-1628768330444.webp
I want to make this URL public so that anyone with this link can view the image.
How can I achieve this?
...ANSWER
Answered 2021-Aug-12 at 12:25You can make an object public by doing these below steps:
- Open the object by choosing the link on the object name.
- Choose the Permissions tab.
- Choose Edit.
- In the Everyone section, select Objects Read.
- Select I understand the effects of these changes on this object.
- Choose Save changes.
This is just one of the ways of doing it. Check the below link for more such ways.

Using the Microsoft tutorial on Audio/Video Capture in Media Foundation, I try to create a media source for a video camera. Code below is directly taken from the aforementioned tutorial:
...ANSWER
Answered 2021-Aug-03 at 15:18In my case, the culprit was a disabled service: Windows Camera Frame Server.
I had to enable it (Automatic startup) through the Services application and start it:
After that the error did not occurred again.
On a related note, I also had to allow applications to access the camera:
Local Group Policy: Computer Configuration / Administrative Templates / Windows Components / App Privacy
"Let Windows apps access the camera" must be set to "Not configured".
QUESTION
- You are given a number n, representing the number of rows.
- You are given a number m, representing the number of columns.
- You are given n*m numbers, representing elements of 2d array a. The numbers can be 1 or 0 only.
- You are standing in the top-left corner and have to reach the bottom-right corner. Only four moves are allowed 't' (1-step up), 'l' (1-step left), 'd' (1-step down) 'r' (1-step right). You can only move to cells which have 0 value in them. You can't move out of the boundaries or in the cells which have value 1 in them (1 means obstacle)
- Complete the body of floodfill function - without changing signature - to print all paths that can be used to move from top-left to bottom-right.

QUESTION
I'm having some problems with MPEG1 videos and Media Foundation: So Media Foundation doesn't support playback of MPEG1 video streams (see here), but for some reason it will still open them and it will even report the correct duration and frame size. So at opening time everything looks like it can play those files.
But it can't! Once you try to actually play the MPEG1 video file, IMFAsyncCallback::Invoke() will be called with a status of MESessionTopologySet and then IMFMediaEvent::GetStatus() will return 0xc004f011 and that's about it.
So is there any way to check if a video format can actually be played by Media Foundation after opening it or is there any way to make Media Foundation only open files that it can actually play? Currently I can only tell if a file can be played or not by attempting to start playback and then see if it works or not which is somewhat inconvenient. I'd like to be able to tell if a file can be played or not much earlier.
...ANSWER
Answered 2020-Oct-31 at 13:09I have solved this now by using IMFSourceReader. I have found out that trying to set the media type to MFVideoFormat_RGB32 will fail with MPEG1 video streams but it will work fine with MPEG4 so this is probably a feasible way to check if Media Foundation can actually play a file. In code, the solution looks like this:
QUESTION
I wanted to implement a question where we find paths in a maze from (0,0) cell to (m-1,n-1) cell with having some obstacles in between.
I have used recursive backtracking algorithm to solve the problem and I just wanted to make some kind of visualization where we can see how the path is been taken as we are travelling in the maze.
I saw that question here
Now I have implemented it using javascript and I am coloring the cells blue which we are visiting and then again removing the color if we backtrack but everything happens very fast as we can't see anything happening, so I tried using sleep() function to have some delay but I don't think I have used them properly as any random pattern is showing not the proper path it is taking.
If anyone could help me in resolving it then it will be a great help.
