Hello, Patchs in attach add 12b decoding for prores Theses patch are based on patch by Kieran Kunhya https://pastebin.com/mYNJkdMH
After theses patch by default Prores 422 are decode in 10b and 444 in 12b I add a user option, to force 10b or 12b decoding Need to be apply after patch "avutil - swscale : add YUVA444P12 and YUVA422P12" 003 : cosmetic, remove unused value 004 : move dsp init after codec tag check (in order to set later decoding precision based on codec_tag by default) 005/006 : rename dsp part for 10b 007/008/009 : reorganize unpack alpha and add 12b alpha decoding 010 : Add 12b idct for prores (keep the 10b version) 011 : In 12b, i have a segfault, for file with non multiple of 16 height. Don't understand why doesn't appear in 10b mode. But like several func, seems to write after the last visible line. I increase buffer height, and set crop bottom. 012 : Add 12b support for 444 by default, and add user option for setting decoding precision 013 : Add fate test for prores with 12b decoding precision Comments welcome Martin
