FranceBB's LUT collection
by Andrew Randrianasulu 16 May '25

16 May '25

forum https://forum.doom9.org/showthread.php?t=176091 it says those LUTs should be usable for ffmpeg's lut3d and therefore for CinGG? github (each *.cube can be several mb's big) https://github.com/FranceBB/LinearTransformation author says they were verified on professional equipment... list includes PAL and NTSC variants for rec. 601....

I tried to add AVC-Intra 100 output profiles
by Andrew Randrianasulu 08 May '25

08 May '25

But not sure if I did this correctly. https://en.wikipedia.org/wiki/AVC-Intra says for AVC-Intra 100: AVC-Intra 100: nominally 100 Mbit/s, size of each frame is fixed CAVLC entropy coding only. All formats are High 4:2:2 Intra Profile, Level 4.1 4:2:2 chrominance sampling frames are not scaled and yeah, this French-language pdf actually says the same: https://web.archive.org/web/20110720215759/http://www.ficam.fr/upload/docum… 50M 100M Standard MPEG-4 part10 AVC/H.264 Profile High 10 Intra High 4:2:2 Intra Level Level 3.2/4.0 Level 4.1 Resolution 1440x1080 / 960x720 1920x1080 / 1280x720 Sampling 4:2:0 4:2:2 Bit rate 54Mbps 111Mbps Block size Y: 8x8, C: 4x4 Intra Prediction Y: 9mode, C: 4mode MBAFF Yes De-block filter No Slice/frame 10 Entropy coding CABAC CAVLC so, I looked up ffmpeg cmd line https://trac.ffmpeg.org/ticket/3597 ffmpeg -v info -i /mnt-data/backup4/vol0/export/CUHK\ 2014-1/V017b.mov -vcodec libx264 -intra -pix_fmt yuv422p10le -vb 100M -x264opts avcintra-class=100 -x264opts colorprim=bt709 -x264opts transfer=bt709 -x264opts colormatrix=bt709 -threads 4 -acodec copy V017b-ffmpeg-git-avcintra100.mov Huh, said I and entered those params in opts file, actually in two files (mp4 and mov containers) mov libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 mp4 libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 both for progressive content, for interlace you must add some more flags: https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-January/035049.html -flags +ildct+ilme -x264opts interlaced=1 Also, there is still lack of (GUI) user notification if file writing failed due to NO SPACE on device :} FFStream::write_packet: write packet failed. file:/dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::encode_frame: encode failed. file: /dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::flush failed :file:/dev/shm/avci_new.mp4 err: Операция не позволена Render::render_single: Session finished. ** rendered 273 frames in 85.585 secs, 3.190 fps Render::render_single: Session finished. ** rendered 273 frames in 85.485 secs, 3.194 fps Render::render_single: Session finished. ** rendered 273 frames in 82.176 secs, 3.322 fps Profile sort of assumes you set project to some supported resolution, framerate, etc, otherwise libx264 will fail with console error message..... I found some talk about AVC-Ultra, there even was patch for x264, but it was not merged: https://mailman.videolan.org/pipermail/x264-devel/2015-September/011412.html Also, I think sound must be uncompressed, but I'm not sure.

proot on termux
by Andrew Randrianasulu 30 Sep '22

30 Sep '22

I have i386 debian 11 on my arm tablet now, but road to it was somewhat bumpy. debootstrap as provided by termux does not like --foreign option, so I tried modification of scrip commands found at https://github.com/sp4rkie/debian-on-termux/blob/master/debian_on_termux_10… (I have Android 10 tablet) $ debootstrap --variant=minbase --exclude=systemd --arch=i386 bullseye deb_11 but you need to set main repo here or create debootstrap/mirror by hand REPO=http://ftp.debian.org/debian/ unset LD_PRELOAD $ proot -0 -b /dev -b /sys -b /proc -b /system -b /apex --link2symlink -r deb_11/ -q qemu-i386 /bin/bash --login (for some reason my system need /system and /apex added to proot bind directories for qemu to function) this worked but ssl / ca-certificates were not installed, and coreutils for some reason needed re-install by dpkg -i /var/cache/apt/archive/pkg.deb also debootstrap/debootstap script had termux pathes in it, so I edited them back for normal Linux/debian pathes after installing /etc/resolv.conf network/apt worked but building man page index was a bit slow.

ffmpeg 5.1 patches
by Andrew Randrianasulu 23 Aug '22

23 Aug '22

I think I located new source file with libavformat seek functions, so now we have more complete set of patches, while I can't be sure if those seeking changes still necessary.... For some reason sending patches as attachments failed, so this time I send them as archive

July release of AppImages
by Phyllis Smith 31 Jul '22

31 Jul '22

The AppImages for July are now available at: https://cinelerra-gg.org/download/images/ Unfortunately, the upgrade of OpenEXR as credited to Manuel V can not be done because I struggled and struggled to find a way to use "without-openexr" to also exclude Imath and could not find a way even tried checking cmake version to exclude and it still uses "forced" for Imath. I do not want to prevent older distrros having "cmake" lower than the required 3.12 from building; as long as they can build correctly "without-openexr'". Hopefully, a solution is still viable. Next following the work of Andrew and testing by Andrea will be testing the FFmpeg 5.1 upgrade. ********************************************************************************************************** *GIT for Cinelerra-GG has the following changes from 07/01/2022-07/31/2022* Library upgrades for the following: Libaom to 3.4.0 from 3.2.0 Libvpx to 1.12.0 from 1.11.0 Minor patches to configure.ac for needed configuration changes by Andrew.

Checked into GIT updated libraries
by Phyllis Smith 29 Jul '22

29 Jul '22

As Andrew provided patch updates and I checked on older versions of O/S (Ubuntu 16 and 32-bit Debian 9.1) the following have been updated: libaom-v3.4.0 (from v3.2.0) libvpx-1.12.0 (from 1.11.0) Be aware that if you switch back and forth between an older and newer version BE SURE TO "rebuild index" on you media file or you will see weirdness like I did because the rendered file is a different size between the old library version and the new library version. This will not be a problem for most people - probably just testers who use the same file names (like I always do!) Also, note that I will try to remember to "Credit" the comment in Git with the author because someone noted that that was not being done in Git. I had always put it in the Releasenotes.pdf as the appropriate place because seen by more people. Only programmers or users who do their own builds ever look at Git, but many more people look at the release notes because they want to see whether or not it is necessary to update to the latest release. So for example this latest checkin has the comment of: "Credit libaom/libvpx teams and Andrew patch update" You can stop reading this now, but I have to say in my defense on this Git oversite is that Git was created by Linus Torvalds (in Europe so was not known in the United States right away) in the year 2005. Although that was 17 years ago, it was not even available during our professional working years where we started out with Control Data Corporation and Cray mainframe computers. So basically the common consensus on the "proper" use of Git checkins is not even on my radar. End of rant!
