No matter cavlc option is set to 0 or 1, the output bitstream is always
cabac mode.
Reproduce: -y -s widthxheight -i widthxheight.yuv -vcodec h264_qsv
-b:v 2000k -maxrate 2000k -cavlc 1 test.h264
Then check the entropy_coding_mode_flag of the encoded bitstream.
It is due to the dulicate option "coder" (which should be deprecated) is set to
cabac
