Hi, Attached are new versions of the PAFF implementation patches. As in prior posts, the three patches are to be applied in order. paff-cosmetics.patch & paff-mmcorename.patch have not changed since last posting. Changed slightly since Michael approved. See previous post for details on what changed. See prior posts for overall description of paff-noindent-substance.patch. Changes since last post: 1. valid_structure member of Picture has been removed; now uses reference member as it was intended. 2. Fixed blocky effects near edges observed in some clips (manifested when second field in pair predicts against first; fixed by drawing edges for first field after decode). 3. Includes modified version of Neil Brown's fix for IDR fields. Known limitations (detailed in prior postings): 1. Error concealer is disabled pending augmentation to handle interlacing after base PAFF implementation is finished. 2. Many PAFF samples will trigger errors in ref pic reordering (abs_diff_pic_num overflow). This is not a PAFF problem. I have a fix for posting in separate thread. Knowing it will take time for complete review/accept, I'd appreciate short-term comments on any additional splitting/cleaning needed. -Jeff
