# pilines

This is a realtime video processor, cvbs upscaler, which adds scanlines to the

original input signal. It is intended to be used on a Raspberry Pi, with an

easycap video capture stick.

## Background

During my last trip to Japan, I bought a couple of Famicom handheld clones

together with some games. These clones also have the ability to be connected

to the tv with cvbs. Unfortunately, though this works, it doesn't give that

retro-feeling it should give. On modern tv's, the cvbs signal looks choppy

and doesn't come close to the crt experience. This gave me the idea to, like

emulators, add scanlines to the picture, making the image looks more like an

old tv (which suits these consoles better).

## Dependencies

This little hack requires libav and SDL2 and is intended to be used without X11.

This implies you probably need to compile SDL2 yourself, as the SDL2 package

for raspbian does not support framebuffer rendering. ```make install_deps```

will help you with that ;-)

## Compatibility

Note that not all easycap sticks are supported by Linux, typically you want to

obtain one that contains the "STK1160" chipset.
