O death, where is thy sting? O grave, where is thy victory? Has anyone really been far even as decided to use even go want to do look more like? It has always been my wish to live honorably, and after my death, to leave to those who come after me my memory in good works. It all keeps tumbling down. The press is the enemy. The press is the enemy. The press is the enemy. The graveyards are full of indispensable men.

jmwg: Josh's mpv Win32 GUI

Download the latest version here.

jmwg is a standalone front end for mpv that adds a Win32, Media Player Classic-esque GUI. mpv is a very good video player, but unfortunately has a very unintuitive interface (at least in my opinion). I greatly appreciate the efforts of the developers behind Media Player Classic Qute Theater, but, at least in my experience, it can be a little finicky at times, not least because Qt never wants to work quite right on Windows.

So, I decided to take advantage of my Claude subscription and vibe code my own! Importantly, this is not a wrapper for libmpv. Most mpv-based players pull frames through libmpv's render API and draw the video themselves, which means OpenGL only, no gpu-next, and frame timing at the mercy of the GUI toolkit. jmwg leaves the renderer alone: mpv draws with its own video output, exactly as it does standalone, and the GUI is just tacked on around the frame.

This thing is probably crawling with bugs and maybe even security issues, so don't use it for anything important, 'k? Send bug reports or feature suggestions to any of the contacts on my home page.
