Summary

This Recommendation provides accompanying reference software for ITU‑T Rec. H.264 | ISO/IEC 14496-10 as an electronic attachment. The software is an integral part of ITU-T Rec. H.264.2.

The purpose of this Recommendation is to provide the following.

• Reference decoder software capable of decoding bitstreams that conform to ITU‑T Rec. H.264 | ISO/IEC 14496‑10 in a manner that conforms to the decoding process specified in ITU‑T Rec. H.264 | ISO/IEC 14496‑10.

• Reference encoder software capable of producing bitstreams that conform to ITU‑T Rec. H.264 | ISO/IEC 14496‑10.

The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to ITU‑T Rec. H.264 | ISO/IEC 14496‑10. Requirements established in ITU‑T Rec. H.264 | ISO/IEC 14496‑10 take precedence over the behaviour of the reference software.

This edition integrates the modifications introduced by Corrigendum 1 (2005-10), which only affected the C source code.

Corrigendum 1 corrected various minor errors in the reference decoder software and additionally provided enhancements of the non-normative example encoding processing. The software version currently in-force is referred to as "JM10.1".

This edition integrates the modifications intoduced by Corrigendum 1 (2005-10), which only affected the C source code.

Foreword

Reference software is useful in aiding users of a video coding standard to establish and test conformance and interoperability, and to educate users and demonstrate the capabilities of the standard. For these purposes, the accompanying software is provided as an aid for the study and implementation of ITU-T Rec. H.264 | ISO/IEC 14496‑10 advanced video coding.

The software has been jointly developed by ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG).
