Foveated 360 Video is a client-server system prototype for streaming 360° videos which leverages parallel algorithms over real-time video transcoding. See https://augmentariumlab.github.io/foveated-360-video for the corresponding video, paper, and slides published in IEEE Virtual Reality 2021.

• Ubuntu 20.04 system with an NVIDIA GPU
• OpenCL headers and NVIDIA drivers
• C++ build tools including g++

• FFmpeg libraries (libavformat-dev, libavcodec-dev, libswscale-dev, ...)
• SDL
• Boost
• Eigen
• zlib

sudo apt install ocl-icd-opencl-dev opencl-headers opencl-c-headers opencl-clhpp-headers
sudo apt install libavformat-dev libavcodec-dev libswscale-dev libavfilter-dev libavutil-dev libavresample-dev
sudo apt install libsdl2-dev libglew-dev libglvnd-dev freeglut3-dev
sudo apt install libboost-dev
sudo apt install zlib1g-dev

Download and extract the 1080p video dataset.

Install all prerequisites and run the following:

• make clean
• make all

Then the server can be started with:

• ./driver.x

The client can be started with:

• ./client_driver.x <server_addr>
• For example, to run on localhost ./client_driver.x ws://localhost:9562

• All source files are in the src folder.
• The transformation functions are written in the OpenCL .cl files.
• 1080p versions of benchmark videos are in the 1080p_videos folder.
