mj_kdl::VideoRecorder Struct Reference

#include <mj_kdl_wrapper.hpp>

Public Attributes
mjvCamera	cam {}
mjvOption	opt {}
void *	_impl = nullptr

Detailed Description

Headless video recorder. Renders frames to an EGL offscreen buffer and pipes raw RGB data to an ffmpeg process, producing an H.264 MP4 without a display server or GLFW window.

Requirements: EGL (libegl-dev) and ffmpeg available in PATH.

Typical usage:

VideoRecorder vr; init_video_recorder(&vr, model, "sim.mp4", VideoResolution::R1080p); vr.cam.azimuth = 135; vr.cam.elevation = -20; vr.cam.distance = 2.5;

for (int i = 0; i < steps; ++i) { mj_step(model, data); record_frame(&vr, model, data); }

cleanup(&vr);
