Description

I find a way to print the direct memory used by the direct byte buffers and mapped byte buffers: https://stackoverflow.com/questions/20058489/is-there-a-way-to-measure-direct-memory-usage-in-java But this solution can only print direct byte buffers. As JavaCV, Is direct byte buffers the only things in the direct memory?

Contributor guide

Research direction
Research how JavaCV uses direct memory and how to measure it, including ByteBuffer and MappedByteBuffer, and consider any other memory pools like off heap memory used by OpenCV or FFmpeg. Refer to JavaCV source code and documentation for details.
