#872 closed defect (fixed)

overwrite SPS parameters when different id SPS is decoded

Reported by: sue.naing Owned by:
Priority: minor Milestone: HM-10.1
Component: HM Version: HM-9.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

In SPS parsing of HM9.0.1, global variables are set equal to parsing data.
(e.g. g_uiMaxCUWidth, g_uiMaxCUDepth)

Therefore, SPS parameters are overwritten when different id SPS is decoded.

Probable fix: move the setting of these globals to the SPS activation xDecTop::xActivateParameterSets().

Before we consider this further, please can you provide a test bitstream that exercises this problem. It should require activation of both SPS, not just sending a second different SPS after the first that is never used.

I guess that test case is easy to create. Just run the encoder twice with different settings and concatenate the bitstreams.

  • Milestone set to HM-10.1
  • Resolution set to fixed
  • Status changed from new to closed

(hopefully) fixed in r3356

could need some double-checking and testing
