at zoomed-in scale the audio timelines randomly drops/shifts the level bars in short bursts. Will attempt to add PNG file that shows this behaviour.

Not all blu-ray disk are the same ...
by Andrew Randrianasulu 06 Jan '23

06 Jan '23

https://superuser.com/questions/879216/how-to-determine-whether-blu-ray-dis… lists two methods one with cdrecord + internet, another one using imgburn === Here's the best way I've found: 1. Determine the manufacturer code and media type of the media. On Linux, I used cdrecord <http://cdrtools.sourceforge.net/private/cdrecord.html> dev=XXX -atip | grep -i 'manufacturer\|media type', where XXX is the code for the Blu-ray burner as listed by cdrecord -scanbus. 2. Look up the manufacturer and media type codes at http://www.blu-raydisc.info/licensee-list/discmanuid-licenseelist.php . The table on that site identifies "recording type" (i.e. HTL or LTH) and also write speed from these codes. === quote end==== site worked when I clicked on link. Apparently LTH should be marked due to their bad compatibility with earlier drives, but .... reality is less stellar :( and in imgburn ==== With image burning software. ImgBurn <http://www.imgburn.com/> for instance. In Imgburn main menu just click on anything writing related. For example, "Write image file to disc" Now a new window pops up Please check that you have the correct burner selected in the left hand side, if you have more than one disc burner. Scroll down on the right pane, and you find the info under "Recorded Mark Polarity" ==== HTL is apparently more durable.... Terje posted link to Canadian site and I did little search on my own https://www.pcworld.com/article/423607/hard-core-data-preservation-the-best… (from 2016) to be honest I newer heard about HTL vs LTH when it comes to BDs.... I found some ASUS drive in my city, so *may be* I'll have some means to test real disks in new year.

commit from cin-CV explaining some copyright
by Andrew Randrianasulu 06 Jan '23

06 Jan '23

==== commit 740d7ccc3bc952c689d9d09aa9d2e7f50d7b4a22 Author: Johannes Sixt <j6t(a)kdbg.org> Date: Thu Oct 8 21:54:48 2009 +0200 Insert license blurb with copyright at the top of source files. The majority of files carry only Adam William's copyright, regardless of whether other people contributed code. The following file are exceptions; they receive the copyright of the person who initially added the file: Andraz Tori cinelerra/exportedl.C cinelerra/exportedl.h cinelerra/exportedl.inc cinelerra/manualgoto.C cinelerra/manualgoto.h cinelerra/manualgoto.inc cinelerra/renderprofiles.C cinelerra/renderprofiles.h cinelerra/renderprofiles.inc Hermann Vosseler plugins/reroute/picon_png.h plugins/reroute/reroute.C Nathan Kurz cinelerra/fileyuv.C cinelerra/fileyuv.h cinelerra/pipe.C cinelerra/pipe.h cinelerra/yuvstream.C cinelerra/yuvstream.h guicast/bcrecentlist.C guicast/bcrecentlist.h Pierre Dumuid cinelerra/labeledit.C cinelerra/labeledit.h cinelerra/labeledit.inc guicast/bcpixmapsw.C guicast/bcpixmapsw.h guicast/bcpixmapsw.inc guicast/bcrelocatablewidget.C guicast/bcrelocatablewidget.h guicast/bcrelocatablewidget.inc guicast/bcwidgetgrid.C guicast/bcwidgetgrid.h guicast/bcwidgetgrid.inc Richard Baverstock cinelerra/filedv.C cinelerra/filedv.h This brings the file contents closer to Adam's Cinelerra 4. lines 7 ===== I currently read whole cinCV changelog and make local branches like this: git checkout -b r1053 c27217d5d014500aa5105222a5dbcb24b80ff30f git checkout master git checkout -b r980 e4a838b79f3de7ab7a64bd5c41d1f9dd90c29364 git checkout master and so on ... makes navigating to specific point in time easier.

Ffmpeg loader in cincv in 2010
by Andrew Randrianasulu 06 Jan '23

06 Jan '23

Oh, memory! I remember I was reading those lines but completely forgot where! ========= https://crazedmuleproductions.blogspot.com/2010_07_01_archive.html?m=0 Friday, July 16, 2010 Green Beret parachutes in to help Cinelerra Unbelievably, just in the past week, the Cinelerra CV community (http://cvs.cinelerra.org/) has had a heavyweight developer parachute in and start fixing stuff all over the place. The guy is Chris "Monty" Montgomery who developed the Ogg multimedia container and Vorbis audio formats (http://en.wikipedia.org/wiki/Chris_Montgomery) He is a developer currently working for Red Hat. Monty, You're The Man! His primary effort has been to yank out the kludgy and incompatible file loader in Cinelerra and replace it using good old FFmpeg. FFmpeg has problems of its own, but a helluva lot less problems than the Cinelerra loader. This is a task that the original developer of Cinelerra, Heroine Warrior (http://www.heroinewarrior.com/) has wisely done with the 4.1 version of Cinelerra. Much props to Father HV, for without him, this blog and Open Source video editing would be very different, if exist at all. ===== Unfortunately xiph.org migrated their git without user directories, so only patches survived reside in directory archived by archive.org (duh!) https://web.archive.org/web/20150323164307/http://people.xiph.org/~xiphmont… not all patches downloadable, but biggest (18 mb!) first one surely is Note, I am not saying code from this experiment directly entered cingg vi cincv (I mistaken files with same names but different content) yet it shows how three separate parts (one from cincv (ffmpeg wrapper class from 2004!)), another from hv (Adam's 2008 experiment) and work by Monty in 2010) formed something users can test!

website link to download overview lead to german page
by Andrew Randrianasulu 05 Jan '23

well, shouldn't it only do this in DE version of site? "Is Cinelerra GG Infinity also available for other operating systems? Cinelerra GG Infinity is available for GNU/Linux and FreeBSD. Due to the lack of professional video editing applications for Linux, Cinelerra was developed for Linux. Cinelerra GG therefore serves as a replacement and for this reason there is no Windows or Mac version. We support up to nine different distributions. Click here to go to the download overview page. " where here leads to https://www.cinelerra-gg.org/de/herunterladen/ real link https://www.cinelerra-gg.org/de/?page_id=3803 as far as my Firefox tell me ...

history for ffmpeg.C
by Andrew Randrianasulu 05 Jan '23

I was puzzled by this https://github.com/cinelerra-cv-team/cincv-exp-akirad-paolo/commits/master/… at very start it says r413: Add a wrapper class for ffmpeg/libavcodec routines, with examples of use in fileyuv. Still in progress, but works for what it does so far. author: nkurz on Sep 7, 2004 I *guees* nkruz = nate=Nathan Kurz <nate(a)verse.com> from CinelerraCV AUTHORS we can see familiar #include <string.h> #include "filebase.h" #include "quicktime.h" #include "ffmpeg.h" #include "guicast.h" FFMPEG::FFMPEG(Asset *asset) { this->asset = asset; codec = 0; context = 0; picture = 0; got_picture = 0; } int FFMPEG::init(char *codec_string) { avcodec_init(); avcodec_register_all(); compare with code merged by William ===== @@ -0,0 +1,393 @@ +#include <string.h> + +#define HAVE_SWSCALER + +#ifdef HAVE_SWSCALER +extern "C" { +#include "libswscale/swscale.h" +} +#endif + + +#include "filebase.h" +#include "quicktime.h" +#include "ffmpeg.h" +#include "guicast.h" + + +FFMPEG::FFMPEG(Asset *asset) { + this->asset = asset; + codec = 0; + context = 0; + picture = 0; + got_picture = 0; +} + +int FFMPEG::init(char *codec_string) { + + avcodec_init(); + avcodec_register_all(); + + CodecID id = codec_id(codec_string); + codec = avcodec_find_decoder(id); + if (codec == NULL) { + printf("FFMPEG::init no decoder for '%s'", codec_string); + return 1; + } + + context = avcodec_alloc_context(); + + if (avcodec_open(context, codec)) { + printf("FFMPEG::init avcodec_open() failed\n"); + } + + picture = avcodec_alloc_frame(); + + + return 0; +} so I think we can relatively accurately conclude ffmpeg.C comes from cinCV development tree. So, I think, license header for this specific file should include all contributors listed in github history Paolo Rampino xiphmont = Monty Montgomery petterreinholdtsen (I think he still around! http://people.skolelinux.org/pere/blog/) Simeon Voelkel Plus, of course, William!

fileffmpeg.C history digging
by Andrew Randrianasulu 05 Jan '23

05 Jan '23

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-r… 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/cinelerra@skolelinux.no/msg12045.html https://www.mail-archive.com/cinelerra@skolelinux.no/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/… 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/696d7a41ec6bc52473… 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 ..?)

AUTHORS file for cinelerra-GG?
by Andrew Randrianasulu 02 Jan '23

02 Jan '23

Because cinelerra-gg is merge of cin hv, cin-cv, various recent contributors on this list and Bill's own work I thought having AUTHORS file in sorce tree root will be good idea. Right now Cin-CV AUTHORS look like this (some emails outdated) hv=Adam Williams <broadcast(a)earthling.net> j6t=Johannes Sixt <johannes.sixt(a)telecom.at> minmax=Andraz Tori <Andraz.tori1(a)guest.arnes.si> herman=Herman Robak < herman(a)skolelinux.no> baver=Richard Baverstock <baver(a)thebeever.com> einar=Einar Runkaru <einarry(a)smail.ee> pere=Petter Reinholdtsen <pere(a)hungry.com> tfheen=Tollef Fog Heen <tollef(a)add.no> andreask=Andreas Kielb <andreaskielb(a)web.de> theraz=Tyler Geddes <tgeddes(a)wgeddes.com> dyce=Gergely Erdelyi <dyce(a)rovidzar.hu> dreamlx=David Arendt <admin(a)prnet.org> ga=Gustavo Iniguez <ga(a)kutxa.homeunix.org> memenk=Michael Eric Menk <meklev(a)osys.grm.hia.no> benjif=Benjamin Flaming <cinelerra(a)solobanjo.com> cobra=Kevin Brosius <cobra(a)compuserve.com> taraba=Mark Taraba <m_taraba(a)yahoo.com> nate=Nathan Kurz <nate(a)verse.com> mammique=Camille Harang <mammique(a)garbure.org> kbielefe=Karl Bielefeldt <uhauufo02(a)sneakemail.com> alexf=Alex Ferrer <alex(a)ftconsult.com> pmdumuid=Pierre Dumuid <pierre.dumuid(a)adelaide.edu.au> giskard=Riccardo Setti <giskard(a)autistici.org> jstewart=Joe Stewart <jstewart(a)lurhq.com> doudou=Sylvain Joyeux <doudou(a)melix.net> rafael2k=Rafael Diniz <rafael(a)riseup.net> nicolasm=Nicolas Maufrais <e.conti(a)gmx.net> raffa=Raffaella Traniello <raffaella.traniello(a)livecom.it> feranick=Nicola Ferralis <feranick(a)hotmail.com> akirad=Paolo Rampino <tuttoainternet(a)gmail.com> All in all 30 authors Cin-CV did a lot of bugfixing, build system , internationalization work, some plugin work. Also IIRC ffmpeg support appeared in some branch of cv "fork" while may be Adam and Bill come up with similar file on their own? cinelerra/cinelerra-5.1/cinelerra/ffmpeg.C contain no attribution ... guess we should track this down in history and fix CinHV aboutperfs.C contain this list (Myself only send literally few oneliners, but I guess my work on cingg merges into it) credits.append(new BC_ListBoxItem("Richard Baverstock")); credits.append(new BC_ListBoxItem("Karl Bielefeldt")); credits.append(new BC_ListBoxItem("Kevin Brosius")); credits.append(new BC_ListBoxItem("Jean-Luc Coulon")); credits.append(new BC_ListBoxItem("Jerome Cornet")); credits.append(new BC_ListBoxItem("Pierre Marc Dumuid")); credits.append(new BC_ListBoxItem("Nicola Ferralis")); credits.append(new BC_ListBoxItem("Alex Ferrer")); credits.append(new BC_ListBoxItem("Gustavo I<C3><B1>iguez")); credits.append(new BC_ListBoxItem("Tefan de Konink")); credits.append(new BC_ListBoxItem("Nathan Kurz")); credits.append(new BC_ListBoxItem("Greg Mekkes")) credits.append(new BC_ListBoxItem("Jean-Michel Poure")); credits.append(new BC_ListBoxItem("Monty Montgomery")); credits.append(new BC_ListBoxItem("Bill Morrow")); #ifdef X_HAVE_UTF8_STRING credits.append(new BC_ListBoxItem("Einar R<C3><BC>nkaru")); #else credits.append(new BC_ListBoxItem("Einar R\374nkaru")); #endif credits.append(new BC_ListBoxItem("Paolo Rampino")); credits.append(new BC_ListBoxItem("Andrew Randrianasulu")); credits.append(new BC_ListBoxItem("Petter Reinholdtsen")); credits.append(new BC_ListBoxItem("Eric Seigne")); credits.append(new BC_ListBoxItem("Johannes Sixt")); credits.append(new BC_ListBoxItem("Joe Stewart")); credits.append(new BC_ListBoxItem("Dan Streetman")); credits.append(new BC_ListBoxItem("Mark Taraba")); credits.append(new BC_ListBoxItem("Andraz Tori")); credits.append(new BC_ListBoxItem("Jonas Wulff")); 25 authors. (with overlap) Tefan de Konik looks like typo? Stefan, may be? https://lists.cinelerra-gg.org/pipermail/cin/2022-January/004602.html I think for cingg specifically we should add Bill, Sergey at very least and Andrea, Phyllis, Terje, IgorB, and other *testers* because without your work we newer had chance to move anywhere near our current state. (i guess we should say list is incomplete in first edition, because fishing out all contributor's names out of mail list archive will take time) I think we can go with second form of list, without emails? Usually email is useful if someone want to ask few questions, but because someone contribute to various cinelerra branches does not mean they are still on it ... So I guess leaving remark about incompleteness and links to current email archive is best we can do?
