#80 worksforme Decoder crash when using (modified) encoder_lowdelay.cfg Heiner Kirchhoffer
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.

#559 worksforme log2_min_coding_block_size_minus3 and log2_diff_max_min_coding_block_size range and semantic bbross pandrivon
Description

Correct me if I am wrong, but I could not find any previous ticket or reflector discussion about range of LCU(CTB) and SCU. The current D7 (d2) do not constraint log2_min_coding_block_size_minus3 neither log2_diff_max_min_coding_block_size. I could not find such constraints in Profile section too (Annex A - A.3.2). However, I guess that Main Profile is currently defined for Max CTB = 64x64?

Another minor note about semantics typo: "Log2CtbSize = log2_min_coding_block_size_minus 3 +3..." should be "Log2CtbSize = log2_min_coding_block_size_minus3 +3..." (remove space)

Same remark for: "The variable Log2MaxTrafoSize is set equal to log2_min_transform_block_size_minus 2 + 2" should be "The variable Log2MaxTrafoSize is set equal to log2_min_transform_block_size_minus2 + 2" (remove space)
