🐙 Kimera (Alpha Work-in-Progress)

Low-latency hardware-accelerated codec-based video streaming utility.

Features

• ⚡ Low-latency (~35ms).
• 🦑 Multi-Platform (Linux, macOS, Windows).
• 🔋 Low-overhead with Hardware Acceleration.
• 🖼️ Works with any codec (HEVC, AVC, VP9, VP8, AV1).
• 🧳 Supports multiple transport streams (UDP, TCP, UNIX, GNURadio).
• 🔑 Encrypted tunnel between TCP peers (TLS v1.3).

Installation

Pre-compiled binary packages will be available once this app reaches beta. For now, if you want to try the pre-release version of the app, you should compile it yourself by following the instructions below.

Dependencies

• C++17 Compiler
• GLFW
• OpenGL ES >3.0 or OpenGL >3.3
• LibAV >12.3
• CMake >3.13
• XCB (For Linux)
• Xcode Toolchain (For macOS)

Linux-Debian

This list will be reduced once Meson is implemented in the next version.

$ sudo apt install libavcodec-dev libavfilter-dev libavutil-dev libavformat-dev libglfw3-dev libyaml-dev libssl-dev build-essential cmake git pkg-config python3 python3-pybind11 python3-dev libwebsocketpp-dev libboost-all-dev

macOS

You will need to compile Google's ANGLE OpenGL ES 3.0 for this to work on macOS. Thank Apple.

Compilation

$ git clone --recursive https://github.com/luigifreitas/kimera.git
$ cd kimera
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make -j
$ sudo make install

Usage

Create a server with the /dev/video0 as input and localhost TCP as output.

$ kimera tx ../examples/linux.yml

Receive the video from the TCP server and display it on the screen.

$ kimera rx ../examples/linux.yml

Roadmap

This is a list of unfinished tasks that I pretend to pursue soon. Pull requests are more than welcome!

• Replace current render with librender.
• Replace CMake with Meson.
• Better WebCodecs support.
• Add WebTransport module.
