So, it seems file was already present in CinHV 4.0 from around aug 2008 https://sourceforge.net/projects/heroines/files/releases/081108/cinelerra-4-... same file present in 4.1 So I guess Monty only noticed it in 4.1 because 4.0 was "hiding" in 081108 folder. https://cinelerra.skolelinux.narkive.com/zRx84EEA/cincv-ffmpeg-based-file-re... this specific archive does not show exact date, but I guess 12 years ago will give us 2010 or so https://www.mail-archive.com/[email protected]/msg12045.html https://www.mail-archive.com/[email protected]/msg11759.html date is [CinCV] FFMPEG-based file reader for cinelerra [link to patch] Monty Montgomery Tue, 13 Jul 2010 02:00:23 -0700 sooo ... I think correct author lines will be 1) Adam's (c) 2008 2) Monty's (c) 2010 3) Paolo Rampino (2012-2014) 4) W.P.Morrow (2015-2020) 3) based on https://github.com/cinelerra-cv-team/cincv-exp-akirad-paolo/commits/master/c... 4) based on https://code.google.com/archive/p/cinelerra/source/default/commits?page=2 "Good1.2Guy 2015-02-20 11:21:11 -0700 bf3a568a7ce3 CV file codec mods + a few fixes " bootstrap.c seems to be part of CinCV build system since initial commit in 2003: https://github.com/cinelerra-cv-team/cinelerra-cv/commit/696d7a41ec6bc524738... Because fileffmpeg.c/ffmpeg.C history is very convolved may be we should put 'evidence' links in header too? (because current CinHV fileffmpeg says 2016-2022 by Adam, I guess it was rewrite of 2008 code ..?)
