| Reference software for H.264 advanced video coding |
ITU-T Recommendation H.264.2 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 incorporates changes made to the reference software for ITU T Rec. H.264 | ISO/IEC 14496-10 advanced video coding. The changes contain improvements of encoder compression capability, bug fixes, speed and memory resource usage improvements, restructuring of the software for readability and ease of software maintenance, and the addition of support for new profiles of H.264. The new profiles are from the set of profiles targeting professional applications that were added to ITU-T Rec. H.264 | ISO/IEC 14496-10 in 2007. No changes were made to the text of the Recommendation.
This Recommendation was developed jointly with ISO/IEC JTC 1/SC 29/WG 11 (MPEG) and corresponds to part of ISO/IEC 14496-5. |
