Media IO Plugin for Nodos

This folder contains the Nodos plugin & subsystem for media I/O workflows. It delivers the core functionality for other video I/O devices such as AJA, Bluefish, webcam and other future video development.

What functionality does MediaIO deliver?

1. Gamma conversions: Gamma node creates 1D LUTs (Lookup Tables) for Gamma_Encoded->linear and linear->Gamma_Encoded conversions.
2. Pixel format conversions: Inside MediaIO, there are pixel format conversion nodes (mostly Compute shaders, but can also be fragment shaders), which handle YCbCr->RGB and RGB->YCbCr conversions. The pixel formats such as YUV8 or v210 are currently supported, but the list is growing every day.
3. Color space matrix: MediaIO also delivers color space conversion matrices such as rec601, rec709, rec2020 color spaces. The ColorMatrix node supports also FullRange and LegalRange (a.k.a. Broadcast Legal, Narrow Range) signal levels.
