# Introduction to OCTOPUS RAW Player
OCTOPUS RAW Player is a multi-platform (Windows/macOS) lightweight video playback application for reviewing RAW video footage from professional cameras. Currently the player supports CinemaDNG RAW ```.dng``` sequences. The OCTOPUS RAW Player leverages native C++ code for low-level decoding and implements our unique sophisticated colour science processing pipeline in OpenCL.

# Getting started for Users

## Basic system requirements
- Windows 10 / macOS 10.10 or newer
- GPU with support for OpenGL 3.2+ and OpenCL 1.2+

## Installation
OCTOPUS RAW Player [releases](https://github.com/octopuscinema/raw-player/releases) are usually installed by launching the Windows ```.msi``` or macOS ```.pkg``` installer file. Alternatively, OCTOPUS RAW Player can be run as a portable single-file executable without installation.

# Getting started for Developers

## Building for Windows
### Dependencies
Building OCTOPUS RAW Player requires Visual Studio 2022 with the C# desktop development workload. The OCTOPUS RAW Player project references several NuGet packages which should be restored (https://docs.microsoft.com/en-us/nuget/consume-packages/package-restore) prior to building.

### Building the solution
The OCTOPUS RAW Player executable for Windows can be built from the ```raw-player/Player.Windows.sln``` solution file. The solution contains both C# and C++ projects (mixed managed/unmanaged code). C++ project dependencies are linked dynamically at run-time - please ensure the C++ projects ```raw-player/Decoders``` are built prior to publishing or launching the debug/release executable.
The native C++ dependancies are statically linked against libjpeg-turbo. The appropriate ```.lib``` static library and header files can be downloaded and installed by running ```raw-player/Decoders/Jpeg/GetDependancies.ps1```

#### Deployment
The ```raw-player/Player.Windows.sln``` solution includes a publish profile to build a standalone single-file executable with an embedded .net runtime. This executable can be run on systems without .net runtimes installed.

## Building for macOS
### Dependencies
Building OCTOPUS RAW Player requires Visual Studio 2022 for Mac (with Xamarin.Mac version 8.12 or newer) and Xcode 13 or newer. The OCTOPUS RAW Player project references several NuGet packages which are normally automatically restored prior to building. (See https://learn.microsoft.com/en-us/visualstudio/mac/nuget-walkthrough?view=vsmac-2022 for more information)

### Building the solution
The OCTOPUS RAW Player application for macOS is built from the ```raw-player/Player.macOS.sln``` C# solution file. Visual Studio for Mac does not support C++ projects - native library dependencies must be built manually from the ```raw-player/Decoders/Decoders.macOS.xcworkspace``` Xcode workspace prior to building the C# solution.
The native C++ dependancies are statically linked against libjpeg-turbo. The appropriate ```.a``` static library and header files can be downloaded and installed by running ```raw-player/Decoders/Jpeg/GetDependancies.sh```
