Adding contextual coding of mb_skip_coeff flag. Using contextual coding of the mkb_skip_coeff flag using the values of this flag from the left and above. There is a small improvement of about 0.15% on Derf: http://www.corp.google.com/~debargha/vp8_results/mbskipcontext.html Refactored to use pred_common.c by adding a new context type. Results on HD set (about 0.66% improvement): http://www.corp.google.com/~debargha/vp8_results/mbskipcontext_hd.html Incliding missing refactoring to use the pred_common utilities.
