This is convert tool that works on cross-platform (Windows, Linux) for Azure Kinect.
This tool converts all data of each stream types (Color, Depth, Infrared) that contained in mkv file to image file.

Sample

Command

k4a_mkv2image -i="./file.mkv" -s=true -d=true

Output

Image files are output in the following folder structure.
Image file name is "<file_index>_<device_timestamp>.jpg".
The file index is sequencial number for output images. The unit of device timestamp is microseconds.
