JVET-AO0006 JVET AHG report: ECM software development (AHG6) [V. Seregin (chair), J. Chen, R. Chernyak, F. Le Léannec, K. Zhang (vice-chairs)]
Software development
ECM software repository is located at https://vcgit.hhi.fraunhofer.de/ecm/ECM.
ECM software is based on VTM-10.0 with enabled MCTF including the update from JVET-V0056, and GOP32, which is very close to VTM-11.0.
VTM-11.0ecm anchor https://vcgit.hhi.fraunhofer.de/ecm/ECM/-/tree/VTM11_ANC is used for ECM performance evaluation.
The following changes were integrated into ECM-19.0:
JVET-AN0168: Regression CCP fusion (Test 2.8a) [MR 962]
JVET-AN0101: Remove single model for ALF-CCCM (Test-5.3a) [MR 964]
JVET-AN0095: Quantization center shift (Test-4.2c*) [MR 965]
JVET-AN0121: split_cu_flag context change (Test 1.1g) [MR 968]
JVET-AN0098: Regularization for ALF-CCCM (Test 5.1a) [MR 967]
JVET-AN0093: Joint reordering GPM with affine...
Decisions
merged
The AHG recommended to:
Continue to develop ECM software.
Improve the software documentation.
Encourage people to report all (potential) bugs that they are finding using GitLab Issues functionality https://vcgit.hhi.fraunhofer.de/ecm/ECM/-/issues.
Encourage people to submit merge requests fixing identified bugs.
Encourage people to continue working on ECM memory consumption reduction.
Encourage people to continue working on speeding up ECM encoder to reduce the simulation time.
