Or maybe rolling them together If I roll the patches together (and include the additional suggestions in PATCH 1), would it be best to just email a new patch, and have these closed? Still struggling with general procedure here a bit... Thanks for bearing with me. Matthew ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

I tend to try to keep each patch related to a single "concept". And of course separating cosmetic and functional changes It's mostly the having to have PATCH 3/4 before PATCH 1/4 prompting this suggestion. Or maybe rolling them together The primary reason for making nice patches it for making runs of git- bisect easier /Tomas ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

I was reluctant to submit so many patches, but I worried at the time that combining them would require an overly long commit message. Maybe I'm being too verbose though... What's the best way to submit a combined patch - from a Patchwork/mailing list perspective? Thanks again for your reviews. I'm happy to make any changes necessary for them to be committed. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

[FFmpeg-devel] [PATCH 4/4] zmbvenc: use unsigned values for score calculations
From: Matthew Fearnley
All the values in score_tab are positive or 0, and so should be the sum
returned by block_cmp().
The logic in zmbv_me() assumes that all 'bv' values will be non-negative,
in order to guarantee an early return if ever bv==0.
