If you didn't know already, NVDEC is the Nintendo Switch's video decoder. Without Epicboy we wouldn't be able to watch videos like Fire Emblem: Three House's intro or The Legend of Zelda: Breath of the Wild's memories.

But that's not the only thing Epicboy has done! Epicboy is also responsible for Asynchronous shader compilation on Vulkan and for GameCube Controller support.

**E:** FFmpeg was kind of a no-brainer. It's fast, it's open sourced, and it's well documented.

There's still some work left for me to finish up for the NVDEC implementation, so I haven't decided on what I'd like to tackle next. All I can say for now is that I genuinely enjoyed GPU related programming.
