Description

When running VTM-7.1 with 1.5x RPR scaling factor, an encoder/decoder mismatch occurs for the sequence RaceHorsesC:

EncoderApp -c ./cfg/encoder_lowdelay_vtm.cfg -c ./cfg/per-sequence/RaceHorsesC.cfg -q 37 --ScalingRatioHor=1.5 --ScalingRatioVer=1.5 --FractionNumFrames=1 --UpscaledOutput=2 --FramesToBeEncoded=150 --SEIDecodedPictureHash=1

DecoderApp -b str.bin -o dec.yuv --UpscaledOutput=2

Attached are the encoder and decoder logs where the MD5 sums show the mismatch.

It seems similar or the same issue was already reported in #734.
Was the provided fix tried?
