RayMarching->OpenCV->ffmpeg

Description

I guess there could have been a lot of better time uses than emulating GLSL shaders in OpenCV and then pipe-ing it to ffmpeg.

Threading is done via openmp, to disable it remove DEFINES from CXXFLAGS in Makefile

HOW TO

• Step0: Prerequisites

Make sure to install OpenCV (preferably the latest one) and install ffmpeg.

• Step1: Compile

g++ main.cpp -std=c++11 -o raymarching `pkg-config opencv --cflags --libs`

or use

make

• Step2: Use

./raymarching | ffmpeg -f rawvideo -pixel_format bgr24 -video_size 320x240 -i - -f mpegts -preset veryslow -vcodec libx264 udp://localhost:5000

Pipe the output directly to ffmpeg with this command

• Step3: Watch

Open VLC player (or SMPlayer) and use CTRL+N (CTRL+U - SMPlayer) to open the stream from URL

udp://@0.0.0.0:5000
