Description

When using encoder_lowdelay.cfg with parameter "GOPSize" set to 4 and parameter "RateGOPSize" set to 4, the decoder crashes at POC 5:

Assertion failed: 0, file ..\..\source\Lib\TLibCommon\TComBitStream.cpp, line 153

The sequence-specific config file used was per-sequence/BlowingBubbles.cfg with parameter "FrameToBeEncoded" set to 10.

A number of other configuration parameters seem to have been changed with respect to the default settings.

HierarchicalCoding : 0 # Hierarchical B coding ON/OFF
LowDelayCoding : 1 # Low-delay coding structure
NRF : 0 # Mark non-reference for highest temporal layer

Is it know whether these have an influence on the reported crash? (which I can reproduce)

Oddly enough, when setting SymbolMode to 0, I get this in the decoder:
