| Summary | 0000373: Artefacts present on decoded sequence - Mismatch between encoder reconstruction & decoder | ||||
| Description | When encoding one specific operating point of the Starcraft sequence using JM 19.0, pink artefacts are present on the decoded sequence in the top left corner (see attached screenshot). These artefacts start with POC 137, then build up over time, and disappear again with POC 192. The artefacts are also present when using a different decoder than JM 19.0. However, the encoder reconstruction of JM does not show this issue. | ||||
| Steps To Reproduce | Command line: lencod.exe -f encoder_randomaccess.cfg -p InputFile="VL_Starcraft_540p60.yuv" -p OutputFile="VL_Starcraft_540p60_QP30.bin" -p ReconFile="VL_Starcraft_540p60_QP30.yuv" -p SourceWidth=960 -p SourceHeight=540 -p QPISlice=30 -p QPPSlice=31 -p QPBSlice=31 -p IntraPeriod=64 -p FramesToBeEncoded=600 -p TraceFile="trace.txt" The config files encoder_randomaccess.cfg and encoder.cfg are attached. The source file is available at (MPEG access required): ftp://mpegcontent@mpegfs.int-evry.fr/MPEG-05/Part02/VerificationTestPhase1Material/1_OriginalHalfRes/VL_Starcraft_540p60.yuv | ||||
