Hi, i recently notices higher cpu activity for some files during playback and found they been rescaled from 720x576 to 720x562.
problem comes from different PAR that files has, actually differently overridden. default consumer *dv_pal* has: [...] sample_aspect_num=16 sample_aspect_den=15 [...] producer *producer_avformat.c* has own PAR override code in *get_aspect_ratio* that setup: 64:45 for PAL 16:9 16:15 for PAL 4:3 32:27 for NTSC 16:9 8:9 for NTSC 4:3 in the same time *producer_libdv.c* defined PAR for video according to ITU Rec.601: 118.0/81.0 for PAL 16:9 40.0/33.0 for NTSC 16:9 59.0/54.0 for PAL 4:3 10.0/11.0 for NTSC 4:3 so, what is solution?: 1. honor ITU 601: change dv_pal profile to 59:54, drop avformat overriding code 2. use non-ITU PARs and fix *producer_libdv.c* to provide non-ITU pixel aspect ratios -- ________________________________________ Maksym Veremeyenko ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
