Use Chrome and a extension to play local videos.

It can be set as the default video file opener, just like you would use other Windows desktop software: double-click to open a local video file in Chrome.

Because NVIDIA release , a new AI-enhanced HDR feature to all GeForce RTX GPUs, instantly converting any Standard Dynamic Range (SDR) video playing in select internet browsers into vibrant High Dynamic Range (HDR).

Sadly, RTX Video HDR and RTX Video Super Resolution work only on Chromium-based browsers such as Google Chrome or Microsoft Edge.

This is why I wrote this program.

Currently only one instance of ChromiumMediaPlayer.exe can be running at the same time.

Simply download the ChromiumMediaPlayer.exe from Release, and run it to configure. Install the extension aforementioned. (Set the browser path manually for other Chromium browsers. (Only tested on Windows 11 21H2, Chrome 120))

Press Win+Alt+B to enable Windows HDR, and adjust SDR brightness in Windows' Display Settings.

In Windows Explorer, right-click -> choose Open With -> navigate to the folder where ChromiumMediaPlayer.exe is located, and choose to open with it or set it as the default.

Read https://webextension.org/listing/the-media-player.html for keyboard shortcuts and other usage FAQs.

Tips: HDR mode is not designed for daily work and usage. Remember to turn off HDR after enjoying videos.

Install Python 3.10 and nuitka, and run nuitka --windows-icon-from-ico=icon-256.ico --output-filename=ChromiumVideoPlayer.exe --standalone main.py .

No other package is required.

Local files are served as local http server.

Huge thanks to devs of the extension!
