API Notes: QTKit framework


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.

The full API is described in Apple’s documentation, both the C and Objective-C APIs are available (but see the API Notes below).

These bindings are accessed through the QTKit package (that is, import QTKit).

API Notes

  • Functions QTMakeTimeWithTimeRecord and QTGetTimeRecord are not supported.
  • The integration with classical Quicktime API is not properly tested at the moment. Furthermore that API is deprecated by Apple, and not available in 64-bit code. Use the QTKit API where possible.


This framework is deprecated in OSX 10.9, use the AVKit and AVFoundation frameworks instead.
