#793 new defect

Mismatch encode decode for YUV400

Component: VTM Version: VTM-7.1
Keywords: Cc: ksuehring, XiangLi, fbossen, jvet@…


The VTM raises an error Exceeded FIFO size reading bitstream.

My source is cloned at the commit bd9038ff700ff886f23fc1834f24ef7c1dec66b8, branch master.

+ My built VTM decoder works well on YUV420.
+ HM (HEVC) decoder can decode the bitstream of YUV400 source but the VTM decoder.
