Austin,
Good question.
entropy_coding_mode_flag, weighted_pred_flag, transform_8x8_mode_flag
(etc) are bit fields of "p->pic_fields" structure.
Indeed "pic_fields" value is enough for "player A" & "player B"
comparison.
But we can print detailed information about sub-fields too for
convenience reasons. Right?
Could you compare, please?
1st case (Now):
Player A Player B
pic_fields = 0x431
pic_fields = 0x435
entropy_coding_mode_flag = 1
entropy_coding_mode_flag = 1
weighted_pred_flag = 0
weighted_pred_flag = 0
weighted_bipred_idc = 0
weighted_bipred_idc = 0
transform_8x8_mode_flag = 1
transform_8x8_mode_flag = 1
field_pic_flag = 1
field_pic_flag = 1
constrained_intra_pred_flag = 0
constrained_intra_pred_flag = 1
pic_order_present_flag = 0
pic_order_present_flag = 0
deblocking_filter_control_present_flag = 0
deblocking_filter_control_present_flag = 0
redundant_pic_cnt_present_flag = 0
redundant_pic_cnt_present_flag = 0
reference_pic_flag = 1
reference_pic_flag = 1
2nd case (Suggestion):
Player A Player B
pic_fields = 0x431
pic_fields = 0x435
entropy_coding_mode_flag = 1
entropy_coding_mode_flag = 1
transform_8x8_mode_flag = 1
transform_8x8_mode_flag = 1
field_pic_flag = 1
field_pic_flag = 1
reference_pic_flag = 1
constrained_intra_pred_flag = 1
reference_pic_flag = 1
IMHO, 2nd case is more convenient for comparison.
It's hard to check difference in 1st case. It's very easy to check in 2nd case
either w/o special comparison tools. Also it's more convenient for development.
I see all information without "trash zero possibilities".
(Indeed player comparison is part of my development. This suggestion (+ patch)
is consequence of my development.)
Austin, what do you think?
Thank you,
Alexander

These fields will not be printed if the value is zero?
We need them to be printed if we want to compare the trace of player
A and player B.
Thanks
