[lance.lmwang@gmail.com]

From: Limin Wang <lance.lmwang@gmail.com>

ffmpeg -y -f lavfi -i testsrc -c:v libopenh264 -profile:v main -coder cavlc -frames:v 1 -bsf trace_headers -f null -

before the patch:
entropy_coding_mode_flag                                    0 = 1

after the patch:
entropy_coding_mode_flag                                    0 = 0
