API Notes: CoreVideo framework

Introduction

An introduction to PyObjC describes the general method for translating Objective-C calls into Python calls, including the handling of pass-by-reference arguments and buffers.

This document describes where the PyObjC bindings for this framework are different from the general rule, such as mentioning APIs that are not supported or where the interface is different than expected.

API Notes

  • These bindings are barely tested in real code
  • A number of API’s aren’t implemented at the moment because they require manual wrappers.
  • Getting and setting values for kCVPixelFormatFillExtendedPixelsCallback is not supported.
