playback | music app built with react and redux | State Container library

I am very new to swift. So TLDR I have a collection view which I want to update after I click a button. I have seen various solutions and everyone suggesting to put collectionView.reloadData but I am not understanding where to put this line in my code. Any help will be appreciated. This is the view controller:

I have made a Python script whose task is to take a video file and split it up into separate videos of 60 secs each. Here's the code.

I'm in making the responsive table using Bootstrap and some items are not aligned at the center of cell because the parent row element has multiple lines for some cells.

So I tried to apply flex-box style to table but it doesn't work well.

What should I do for sitting the element at the center of table.

I'm trying to work with an old version of DirectX (8.1) and I'm finding the documentation more than a little confusing. It feels like the IDirectMusicPerformance8 interface is for MIDI playback, as it has various MIDI-related methods on it, but various parts of the documentation suggest that it can be used to play back WAV data as well. For instance, the tutorial says that you call InitAudio on the performance, and it states "Wave files require only a single performance channel, and MIDI files require up to 16".

So is it for MIDI or can it be used for WAV?

If it can be used for WAV, I'm even more stumped, because I'm initializing it, running performance->PlaySegment(segment, 0, 0, NULL), getting a success response, but the audio is silent.

I am developing a Media Player app and the min API level that I want it to support is API 22.

I want to use Audio Focus for the media playback, but the AudioFocusRequest.Builder() doesn't work on API levels lower than API 26 and the method requestAudioFocus() that used to work on API levels less than API 26 is deprecated now, so how can I use Audio Focus in the app so that it works on API levels less than API 26 and also on higher API levels as well?

I have created a Camera using AVFoundation which is able to record video and audio using AVCaptureVideoDataOutput and AVCaptureAudioDataOutput. I create my capture session, attach all inputs and the video- and audio-data outputs, and the Camera then sits idle. The user is now able to start a video recording.

The problem with this is that immediately after I start the capture session (captureSession.startRunning()), the background music stutters. I assume this is because once the capture session starts running, the AVCaptureAudioDataOutput internally activates the AVAudioSession (AVAudioSession.setActive(...)), which I don't want it doing. I want it sitting idle (and not providing any audio output buffers) until I explicitly activate the Audio Session (once the user starts recording).

This is really annoying, since the Camera is the start-screen in our app and everytime the user opens or closes the app his music stutters.

I know that this is somehow possible because Snapchat works that way - you open the App and background audio smoothly continues to play. Once you start recording, there is a small stutter on the background music, but the Camera smoothly operates and starts recording once the short stutter is over.

My code:

I have been trying for a while to get this fixed but I haven't seen any solutions online on this topic yet.

The problem is when using MonoGame with the Platform DesktopGL, the Window.Handle seems invalid. As attempting to get a Window/Form from this Handle returns null, further supporting this would be BASS.Net Not being able to play audio on this Window Handle,

Here's part of my code that's attempting to use the Handle (Uses Bass.Net for Audio Playback):

The use-case is that I want the user to be able to preview a song hosted at a remote URL. Fine, you say, just use AVPlayer. Yes, but I want to be able to cache the file locally if it is completely downloaded in the course of being previewed. As far as I can tell, there's no way to access the local data that AVPlayer downloads for its streaming playback. Likewise, there's no way to get access to the data being downloaded by URLSession until it is completely downloaded. So, I'd like to find a result using one of these approaches:

1. Access the data in AVPlayer once it has completed downloading it and save to a file.
2. Download the data progressively to the cached URL and have AVPlayer play it as enough data becomes available.

Are either of these scenarios possible? Is there some other scenario which will achieve what I am looking to do?

I want to change the values of the buttons on the page with Tampermonkey, but I can't change it because it says the button is undefined?
