Player | ▶ Simple and lightweight, yet polished and powerful Android video player based on ExoPlayer | Android library

Say that I have the following interface:

I am creating a custom video player, I would like to add a video preview when the user hovers a progress bar.

I am able to generate thumbnails using FFmpeg as follows.

I'm using Exoplayer in my app and initializing exoplayer as

I'm writing web pages in markdown and converting them to HTML using md2html tool. I want to process the output HTML file and find any youtube link like this:

https://www.youtube.com/watch?v=abcdefgh887

and replace it with the embed code:

I toyed around a little with Grammars, mostly to get familiar with them, but concluded this probably isn't the ideal tool for the job. Plus I'd prefer to use existing modules that are easily adaptable to other similar tasks rather than roll my own half-baked solution.

Perl5 has some good tools for this kind of thing but I'd like to use a pure Raku solution so I can learn more Raku.

Any recommendations for good approaches to this problem?

I don't know if this is possible, but I am trying to take the image of a custom outdoor football field layout and have the players' GPS coordinates correspond to the image xand y position. This way, it can be viewed via the app to show the players' current location on the field as a sort of live tracking.

I have also looked into this Convert GPS coordinates to coordinate plane. The problem is that I don't know if this would work and wanted to confirm beforehand. The image provided in the post was for indoor location, and it was from 11 years ago.

I used Location and Google Maps packages for flutter. The player's latitude and longitude correspond to the actual latitude and longitude that the simulator in the android studio shows when tested.

The layout in question and a close comparison to the result I am looking for.

Any help on this matter would be appreciated highly, and thanks in advance for all the help.

Edit:

After looking more at the matter I tried the answer of this post GPS Conversion - pixel coords to GPS coords, but it wasn't working as intended. I took some points on the image and the correspond coordinates, and followed the same logic that the answer used, but reversed it to give me the actual image X, Ypositions.

The formula that was given in the post above:

The following code gets player data but each dataset is different. The first data it sees is the quarterback data, so it uses these columns for all the data going forward. How can I change the header so that for every different dataset it encounters, the correct headers are used with the correct data?

I'm working on a ROBLOX project and I'm trying to make it so that when a player touches a brick (we'll say... a finish line!), it adds them to a table called winners.

How do I get every entry in winners, separate them with a comma (apart from the last one, that would look like: test, test2, test3, which looks weird) and then put them into one whole string to go into a StringValue in ReplicatedStorage.

Here is what I have so far:

In my game, I changed the list of players from canvas to html, due to which a vulnerability appeared that any player can give himself a name into which he can insert js code, for example, which will work for all players when the player appears in the player list. The question is, how to make html not work and everything that the player enters is displayed as text? The pre tag in html didn't help me :(

The code for adding a player to the player list:

I am building an online course website. When the user watches a lesson in full-screen mode, I want to remember that, so as to use full-screen mode when I mount react-player with the next lesson. I hoped there would be an onFullscreenMode callback, but the documentation does not list anything of the kind. How can I achieve this?

Edit 1: Based on the reply of @onkarruikar, I tried using screenfull. First, I was surprised that it was not installed although real-player was supposed to use it to enter full-screen mode. After installing the package and importing it, I get the compilation error:
