But you're only starting one new thread, which does mostly all the work. So the performance obviously won't increase much. Start something like 4 threads that simultaniously render different frames to the buffer, then you'll get seriously improved performance.

Just be very mindful of thread safety if you ever re-use ImageData - it's possible to have ImageData:mapPixel be working on a different thread while love.graphics.newImage is copying the ImageData from RAM to VRAM at the same time, garbling the resulting graphics image.

Use Love JIT, use shaders when available. There you go.

I don't see any problem doing a multithreaded approach here. Doing calculations on the GPU is good generally, but I think the heaviest part of calculations come from parsing the images, and that's certainly easier to do with LÖVEs standard functions. With 4 cores, getting 80 FPS even for a decently high res video should be possible (since I get around 20 FPS single core).

I wonder the same, what license is this using?
Kind of in a hurry, got a deadline for a gamejam at the end of the month.
But honestly, video in LÖVE. This is the day of glory.
Great job!

VLC can convert more or less any video to mjpeg + ogg.

Hmm, I'm not sure about license thing. It is not so much work actually. So you can just treat it as a free example code. No credits is required.

If you really don't want credits or anything like that, I suggest you waive your rights with CC0, and clearly state that near the download link to the library. That way, it's clear to everyone it's free to use in any way they like without having to credit you.
