Module cm 

Available on crate feature cm only.

Core Media time, buffer, and format-description wrappers. CoreMedia primitives — CMTime, CMSampleBuffer, CMBlockBuffer, CMFormatDescription, audio buffer list bridging.

These are the framework-agnostic value types and reference-counted wrappers shared by every Apple media framework. ScreenCaptureKit / VideoToolbox / AVFoundation / AVAssetWriter all speak CMSampleBuffer, and this module is the single source of truth for the safe Rust wrapper.

The image-buffer accessor (CMSampleBuffer::image_buffer) is gated behind the cv feature so users who only need CMSampleBuffer for audio / encoded video don’t pay the CoreVideo dependency cost. The SCStreamFrameInfo attachment readers stay in screencapturekit-rs since they’re tied to ScreenCaptureKit’s specific attachment keys.
