Webfrontend for watching videos in the laptop

Hi, I have rephrased the text. The original one is down there.

My laptop is connected to my TV via HDMI. I now want to select a movie on my smartphone, play it on the laptop and output it on my TV.
It seems more comfortable that way than crawling to the laptop and selecting the movie there and then placing it in front of the TV.

I have already gotten some good ways to do that via Jellyfin or through some sort of remote app.

Thank all of you and I will gladly take more ideas. I will test some in the evening.

Original:

I've been searching for a while for a way to watch the videos in my laptop in my TV without having to access my laptop directly.

So I need some kind of webfrontend (preferably a docker container) where I can select my videos via a website and output them through HDMI.

Unfortunately I have not yet found anything like that, mostly because searching it only produces results telling you about streaming services like jellyfin and how to set them up.

Is there a way to do this yet?
