M36400: Proposed Patch for AVC Reference Software - GreenMPEG SEI parsing
The group thanks Vitec for providing the reference software.
The reference software decodes and displays the Green Metadata SEI message as specified in w15211.
The patch has been released in JM 19.0.
M36401: Evaluation of the Green Metadata
Accuracy of the complexity metrics was studied using the metadata generator for the reference bitstreams in m36398.
The complexity model is most accurate for entropy decoding (98%), then interpolation filtering (95%), intra prediction (90%), deblocking filter (88%), interpolation filter (95%). The IDCT modeling is least accurate at 60%.
For intra prediction, the accuracy for I-frames needs further study because the number of cycles consumed is highly variable.
For the interpolation filter, the accuracy needs to be confirmed after the 10% improvement mentioned in m36398 is implemented.
The proponents are encouraged to study energy consumption over a wide range of bitstreams such as those used for the CfP.
