Improve LibreTube Screen Reader Accessibility

[slannon97]

Steps to reproduce

I'm totally blind and use this application with a device called the SensePlayer which is a blindness product from a company called HIMS that runs Android. I installed the app from F-Droid and it works very well. However, there are many unlabeled buttons that just say button unlabeled. Please add proper accessibility labels to the buttons so a screen reader user knows what they do. For example, instead of saying button, the screen reader would say rewind button.
You can test the app using any Android phone with the TalkBack screen reader installed. Go to Settings>Accessibility>TalkBack and turn it on. For basic navigation, swipe left or right to move to the previous or next control, and tap the screen twice with a finger to select the item that's focused. You can also touch controls to select them and then double tap to activate. If your device doesn't have TalkBack installed, download Android Accessibility Suite from Google Play. Improving the accessibility will make the app better for any Android device and screen reader that uses the standard Android accessibility APIs. Here's a page from Google that may help and of course, let me know if there's anything else I can do to help. I'm not a developer, but I'll do my best to provide any information you need. However, labeling buttons is one of the easiest things you can do to make the experience significantly better.

Expected behavior

When navigating through the controls using a screen reader, their purpose should be clearly indicated by labels. For example, rewind button, fast forward button, play button, etc.

Actual behavior

The app is usable, but it is confusing to hear button button button when navigating the interface. Close your eyes and try navigating. Hearing button button button isn't very helpful. The first question that comes to mind is what does that button do? Adding labels would go a long way to making the experience much more enjoyable for screen reader users.

LibreTube version

Other details

You may want to start by examining the playback screen while a video is playing. The unlabeled buttons here are the most important, as it's very difficult to know what's going on and which button corresponds to which function.

I've already added some labels in #4472, it's probably a good idea to take another look once the new version is released.

There has been a new release with the aforementioned changes. Please check which problems still exist and which ones need further improvements.

More buttons have labels, but it's a little strange, because it says button unlabeled before the label. I'll try to produce a screen recording soon using my Pixel 7.
