Add fix for issue 958/667 under FIX_958_667_DISABLE_INITIAL_PLC_SUPPRESSION
requested to merge 958-suppressing-output-of-initial-lost-frames-causes-non-be-in-evs-basop into main
- Related issues: #958 (closed)
- Requested reviewers: @bayers
Reason why this change is needed
- The handling of initial lost frames in IVAS causes a non-BE on 26.444 in the IVAS BASOP, EVS operation.
Description of the change
- The
hIvasDec->hasDecodedFirstGoodFrame = trueis set for EVS operation. The number of channels is known and the output may be generated, even if the PLC output before any frames have been decoded should not be relevant. In float operation it seems to be zero for the given test case, but in BASOP some fluctuations of 1 LSB is generated.
Affected operating points
- None observed in IVAS/EVS float, but when the functionality is used in combination with EVS BASOP operation a difference is seen for the 26.444 bitstream
stv16n2_96_1280_16kHz.EPF.COD.
