PUBLIC BETA NOTICE

OpenTimelineIO is currently in Public Beta. That means that it may be missing some essential features and there are large changes planned. During this phase we actively encourage you to provide feedback, requests, comments, and/or contributions.

Overview

OpenTimelineIO is an interchange format and API for editorial cut information. OTIO is not a container format for media, rather it contains information about the order and length of cuts and references to external media. This repository contains the Java bindings built over the C++ core which you can find here.

OTIO includes both a file format and an API for manipulating that format. It also implements a dependency-less library for dealing strictly with time, opentime.

You can provide adapters for your video editing tool or pipeline as needed.

The OpenTimelineIO core is written in C++. This repository hosts C bindings for OpenTimelineIO.

Prerequisites

CMake 3.17.0+ (Windows) or CMake 3.9.4+ (Linux and macOS)
Compiler with C++11 support

Dependencies

OpenTimelineIO: OpenTimelineIO-C-Bindings is a C-wrapper over the OpenTimelineIO C++ core
cmocka: It is a unit testing framework for C used here to test the bindings.

Building OpenTimelineIO-C-Bindings

OpenTimelineIO-C-Bindings have been built and tested on Ubuntu 18.04LTS, Windows 10 and macOS. Follow these instructions to build the C bindings.

git clone --recurse-submodules https://github.com/OpenTimelineIO/OpenTimelineIO-C-Bindings

cd OpenTimelineIO-C-Bindings

mkdir build

cd build

cmake .. {CMAKE OPTIONS}

cmake --build . --config {Debug/Release}

To run the tests from the build directory run:

ctest

CMAKE OPTION	VALID VALUES
CMAKE_INSTALL_PREFIX	{SOME PATH}	Install the libs to this path (`usr/lib/` by default on Linux/macOS)
COTIO_INSTALL	ON/OFF	Install the C bindings (ON by default)
COTIO_SHARED_LIBS	ON/OFF	Build shared if ON, static if OFF (OFF by default)
COTIO_AUTOMATIC_SUBMODULES	ON/OFF	Fetch submodules automatically (ON by default)

Examples

Looking through the unit tests is a great way to see what OTIO can do. See here.
