ECM-11.0 decoding mismatch when DualITree is off
Decoding mismatch was observed for ECM-11.0 software when DualITree is off by command line. The issue could be reproduced by command: ./EncoderAppStatic -c encoder_intra_ecm.cfg -c RaceHorses.cfg -i RaceHorses_416x240_30.yuv -fs 0 -f 40 -q 37 -ip 1 --DualITree=0 --PrintHexPSNR=1 -dph 1 -v 6
