Bug related to CAVLC coding

Reported by: libin Owned by:
Priority: minor Milestone:
Component: HM Version: HM-4.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

When encoding some sequences with very low QP, (such as SlideShow_1280x720_20, intra_loco, QP=2, RDOQ off, frame 2), the encoding crashed. That was caused by the limitation of the length of one code word in CAVLC.
In that extreme case, some coefficients may be very large (more than 16000), and
assert( uiNumberOfBits <= 32 );
in TComOutputBitstream::write() fails.
