/multi-rate-HEVC

Multi-rate HEVC encoder based on HM 16.7 that implements a CU structure reuse from a high-quality reference to lower-quality dependent encodings, as described in: D. Schroeder, P. Rehm, and E. Steinbach, "Block structure reuse for multi-rate High Efficiency Video Coding", Proc. IEEE ICIP 2015, Sep. 2015, Québec, Canada.

This software implements the CU structure reuse method proposed in the paper: D. Schroeder, P. Rehm, and E. Steinbach, "Block structure reuse for multi-rate High Efficiency Video Coding", Proc. IEEE International Conference on Image Processing (ICIP), Sep. 2015, Quebec, Canada. A free copy of this paper can be found at: http://www.lmt.ei.tum.de/forschung/publikationen/dateien/Schroeder2015Blockstructurereusefor.pdf

The software used in the paper was based on the HEVC reference software HM 16.2. Present software is based on the latest version (at this point) HM 16.7. The original README of the HM package can be found below.


====================================================
HOW TO
====================================================

A new CLI option has been introduced: -mrmode

DEFAULT
By default, the multi-rate encoding mode is off.

WRITE MODE (-mrmode 1):
When mrmode is 1, a file called analysisData.bin containing the CU structure of the present (reference) encoding will be created.

LOAD MODE (-mrmode 2):
When mrmode is 2, the (previously created) analysisData.bin file is read and the present (dependent) encoding is shortened according to the method proposed in the paper.


example:
./TAppEncoderStatic -c encoder_randomacess_main.cfg -q 22 -mrmode 1
./TAppEncoderStatic -c encoder_randomacess_main.cfg -q 27 -mrmode 2
./TAppEncoderStatic -c encoder_randomacess_main.cfg -q 32 -mrmode 2
./TAppEncoderStatic -c encoder_randomacess_main.cfg -q 37 -mrmode 2

This software package is the reference software for Rec. ITU-T H.265 | ISO/IEC 23008-2 High efficiency video coding (HEVC). The reference software includes both encoder and decoder functionality.

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, this software is provided as an aid for the study and implementation of Rec. ITU-T H.265 | ISO/IEC 23008-2 High efficiency video coding.

The software has been jointly developed by the ITU-T Video Coding Experts Group (VCEG, Question 6 of ITU-T Study Group 16) and the ISO/IEC Moving Picture Experts Group (MPEG, Working Group 11 of Subcommittee 29 of ISO/IEC Joint Technical Committee 1).

A software manual, which contains usage instructions, can be found in the "doc" subdirectory of this software package.
