I’m not entirely sure, but that would mean that the laptop’s display would have to be connected to both the integrated graphics unit and the dedicated graphics chip. I suspect that this will not be the case with most laptops.

The ssh tunnel might not work because the linux os reserves the ports 0-1023 to OS. You need higher priviliges to reserve this ports for your applications. If you type sudo ss -tulpn you can see the applications that are bound to you ports. Do you see nginx behind local addresses 0.0.0.0:80 and [::]:80 ?

The matrix client element has video and voice chats as beta feature. I use it and it works fine for me. I can absolutely recommend Element as a Discord alternative.

Did you try to install ffmpeg and run: „ffmpeg -i someFile.fileextension -c:a libmp3lame -c:v libx264 -f mp4 outFile.mp4“ to repair the file. Then you should be able to play it on every device. On windows you can install ffmpeg with winget and on linux for example with apt or on macos with brew.
