# Processing Video implementation for Android
This library tries to expose the same API endpoints as that of processing-video library for PC. The sketch from processing-video library works for Android.
This library tries to expose the same API endpoints as that of processing-video library for PC.
Any sketches using the processing-video library should work the same when using this library on Android.

**Behind the hood :**

The idea is to render camera preview on a `SurfaceTexture` and as soon as the new frame is received, copy the data from this `SurfaceTexture` to a custom texure bound to target `GL_TEXTURE_2D` (Note : We cannot directly render to a texture bound to `GL_TEXTURE_2D` target, because for the preview to happen, the texture must be bound to `GL_TEXTURE_EXTERNAL_OES`). This custom texture is then rendered to a PGraphics object. The backing texture of that PGraphics object is then used as the texture cache for our PImage file which stores the video.

## Building the Project

`gradle dist` will build the project, copy it to the user's Processing sketchbook folder, and prepare a .zip file ready for distribution.
