Description

Hello, I am having a problem while working with svo (and svo2) files.

I have a program written in C++ that opens an SVO file and retrieves an image. The issue is that after calling sl::Mat.free() and sl::Camera::close() the memory is not freed and the used memory continues to add up with subsecuent calls to sl::Camera::open()

The solutions proposed in #534 did not work.

Steps to Reproduce

1. Open an SVO file.
2. Grab images.
3. Close the SVO file.

Expected Result

After calling sl::Camera::close() the memory should be freed.

Actual Result

The memory usage is never reduced.
