This simple camera application makes it possible to record both color and stereo IR video streams from Intel RealSense cameras to a single H.264/MP4 file.
This is free and open source software (FOSS), with source available at https://gitlab.com/neuroeventlabs/tools/realsense-android
Parts of this application are derived from the RealSense SDK: https://github.com/IntelRealSense/librealsense
