Detailed Description

C++ wrapper for mlt_image – a decoded video frame buffer.

Holds a raw pixel buffer together with its format metadata (width, height, image format, colorspace). Supports multi-plane formats via plane() and stride(). Use alloc() to allocate a new buffer, or construct from an existing mlt_image handle obtained from a Frame.
