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.

offtopic: Quantel boxes
by Andrew Randrianasulu 25 Aug '24

25 Aug '24

Because I monitor mame WIP thread I saw some news about Quantel Paintbox emulation in MAME (0) and then I randomly followed some links to other Quantel systems Like HAL (basically like hardware compositor) http://dexterslab2013.blogspot.com/2018/03/quantel-hal-video-compositing-sy… 99 layers of SD images or video, up to 15 min storage on 20 disk array! https://m.youtube.com/watch?v=4k15hpeGzBA if you have half of hour you can watch this demo from 1997. Biggest thing so far for me? We are free to use old-fashioned optical effects in front of real camera too :) (0) - https://forums.bannister.org/ubbthreads.php?ubb=showflat&Number=120292&page…

New release update
by Phyllis Smith 19 Jul '24

19 Jul '24

October 2022 end of month new release AppImages now available. This includes a fix for a minor ffmpeg 5.1 security flaw that Andrew discovered and made us a patch for. Full release notes at: https://cinelerra-gg.org/download/releasenotes.pdf . ************ October Release Notes update ****************** *Security flaw in FFmpeg 5.1* was discovered and Andrew forwarded the patch for us to use. A *Direct Copy speed-up* has been added for EXR and PPM sequences that Andrew found. Tiny corrections and addition to Cinelerra_factory presets and plugin.opts. Newer versions of Ubuntu require an additional package install for *bld_prepare.sh as Goat found*. The Manual has had another section added, *Alternative Views of Overlay Modes*, which presents a more “real world” usage display of the overlay modes using a color/black & white gradient + video.

selectable vaapi decoder device
by Andrew Randrianasulu 22 Sep '23

22 Sep '23

Because I have this dual-gpu laptop with intel and radeon (r600) decoding devices I tried to get second (mesa/r600) device going but init failed .. I looked into decoding example: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e and created attached patch now you can select your specific device with env variable: CIN_DRM_DEC=/dev/dri/renderD129 DRI_PRIME=1 LIBVA_DRIVER_NAME=r600 bin/cin in theory same treatment can be applied (with different variable name) to second instance of av_hwdevice_ctx_create (in hw encoder init) but I have no device to test it ...

Monthly AppImage updates
by Phyllis Smith 05 Sep '23

05 Sep '23

April 30th AppImages are now available with the binary only updated with X264 r3106 stable mods. But, I have a problem with being able to update the GIT repository on the server due to some error I made which I am now working on. Release Notes Update below: *********************************** GIT for Cinelerra-GG has the following changes from 04/01/2023-04/30/2023 *Server Maintenance work has been done by Sam* on an ongoing basis along with the difficult task of accommodating newer requirements by Google Gmail. Changes to the Mailing List settings for compliance was very time-consuming and much appreciation goes to Sam for continuing to volunteer his time for critical needs. *X264 *has been upgraded to r3106 stable release. There appears to be no X265 stable updates. *Clang-16* related modifications in thirdparty/Makefile, libuuid-1.0.3, and mpeg2enc.c to support new termux distro have been contributed by *Andrew*. *Prores_ks *render format has had the Apple writing library added as the default with ffmpeg since that is who created this specific prores format. This should make the rendered video more compatible with other software products. Mod provided by *Andrea*.

Using https://openexr.com/en/latest/HelloWorld.html as example so for now I have base commit d51dc1ff2dbd920c6488af4380b8064c9b6a7b4c (origin/master, origin/HEAD) Author: Good Guy <good1.2guy(a)gmail.com> Date: Tue Aug 29 20:20:10 2023 -0600 Credit Andrew - rest of fix for Arch (and termux) which includes thirdparty/Makefile plus commit afa6a601fd3228be18aef413061b3d0165344d7c (HEAD -> master) Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 07:27:57 2023 +0300 Fileext reading error handling for bg render commit cac447973db936f7d5594c83521c34f3e5a9c187 Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 05:27:10 2023 +0300 Add libjpeg dep to.libtiff in thirdparty/Makefile commit 8297b38e49da0ce73e119138c158e806eb1fb45d Author: Andrew Randrianasulu <randrianasulu(a)gmail.com> Date: Wed Aug 30 02:48:47 2023 +0300 Possible fix for ffmpeg 4.4 in pluginfclient.C ==== so, ffmpeg 5.1 based cin seems to work on Slackware 15.0 i586 (with some self-build packages). Tested adding ffmpeg video filter to video track, and of course background render with on-the-fly compressor switch. aggrh, in commit message fileert instead of fileexr. I hope this is not a big problem will try my virtual machines next
