May 2026 - Cin - Cinelerra-GG Mailing Lists

Finalized new server website + updated AppImages and release notes
by Phyllis Smith 31 May '26

31 May '26

Of course, the big news for the month of May is all of the work that Sam did on finalizing/updating the cinelerra-gg.org website on a new server. This was very much appreciated because the original server/format was put into effect in 2018. AppImages have been updated. The month of May release notes portion is below and I apologize if I forgot to get everything in there that was done. ********** Release Notes ********** GIT for Cinelerra-GG has the following changes from 05/01/2026-05/31/2026 *Website major work by Sam:* Totally updated www.cinelerra-gg.org website released on new server on May 12. As previously announced you can now easily get to the location you need via the website or use these directly: - Mailing list cin(a)lists.cinelerra-gg.org - Bug tracker bug.cinelerra-gg.org - Download server download.cinelerra-gg.org - Git server git.cinelerra-gg.org *Mail *was moved from a third-party provider to Mailcow on the server on 5/1. Advantages include: - Independence from external providers. - Full control over spam filtering, DKIM, archives. - One server, one bill, simpler administration long-term. - Better integration with the new Discourse Forum which sends notification mail through this server. *Forum* has been switched from WordPress to Discourse – a much better supported modern, dedicated forum connected directly to Mail. This has the same advantages as listed above for Mail. IgorB contributed an image for the website that was less confusing without console/multi-monitors. *Andrew-R work:* - Accept “q” as an additional option in the tipwindow to close in addition to current ESC, w, RETURN. - Remove turbojpeg-specific library build from turbojpeg which is not being used in CinGG. - *Updated x265* from 4.0 to 4.2 which now includes enabling of HEVC alpha encoding with addition of render format: h265_alpha.mp4. - A new command line switch “-l” has been added with the default working the same as before without using this new “-l” parameter; that is the default of the “l” loadmode of “replace current”. The most Useful values to set are 2 to load concatenated on one track (for jpegs) or 6 to load as resources only. Example usage: bin/cin -l 6 ~/*.jpg or bin/cin -l 2 ~/*.jpg. - Build fixes for BSD version 15.0 have been added. - There is now *lcms2* configure support for internal ffmpeg. *Andrea* tested and provided a lot of feedback as a result. This option defaults to auto and was tested as working with lcms2 2.18. Probably additional testing and usage is needed. - Simple *opencolorio* enable for ffmpeg is also now available but has not been tested to any extent.

Patch: build fixes for FreeBSD 15.0
by Andrew Randrianasulu 26 May '26

26 May '26

I decided to try new BSD and of course something changed since last time I tried, spend some time troubleshooting configure script, turned out echo as built in and echo as /bin/echo behave differently! So I hope I fixed our scripts without breaking Linuxes. I patched cingg on Termux and there configure appeared and worked.

Tested nvenc profile on GT 710, it works.
by Andrew Randrianasulu 21 May '26

21 May '26

Hello all. I *finally* hauled home another desktop bought second hand, and installed my "old" GeForce 710 in it. Installed some version of Slackel ( Slackware -current from nov 2023) on it, and partially updated it. Installed proprietary 470 drivers from Slackbuilds.org link (280 mb!). There was not enough headers to compile this driver, so I compiled kernel first with its embedded config (modprobe configs, zcat /proc/config.gz > .config, make in Linux source tree). After around two hours on this Sandybridge -era i5 at 3.19Ghz + 4gb ram + mechanical 250 gb sata drive formatted as ext4 I got my kernel and proprietary driver installed, escaped world of 640*480 into my glorious 1400*900 native resolution. Compiled cingg from git, in around 45 minutes. Loaded few videos I downloaded from samples.mplayerhq.hu, tried h264 nvenc (I was careful to replace ffnvheaders with our old 2020 version, thankfully provided in tree.) At first it was failing at 97%, but then I realized all failing vids set cingg correctly to interlaced mode, as they were interlaced. Progressive 720p 60 fps mpeg2 dreamtime.mpg from HDTV folder played ok, and encoded with nvenc at around 73 fps. So, new toy is a bit noisy and can heat up to 85 C under full load, but now I hopefully can test for regressions on this front again. Also compiled qemu from git (it worked) and cinelerra-cv from my fork at github (Randrianasulu/cinelerra-cv-randrik, branch "wip"). Its mpeg decoder worked when compiled on older glibc 2.30+ gcc 5.5.0 based Slackware, but crashed under Debian 11 (glibc 2.31,gcc 10.something) and this not completely current -current Slackware with gcc 13.2.0 . I tried to debug this, but no success so far. Otherwise it works, mostly on pre-converted to mjpeg + pcm .mov files with help of modern ffmpeg. At some point I'll manually switch my keyboard, mouse and monitor back to main machine, they both know how to "sleep" properly, so I can leave them in such state and wake up from keyboard (this function was problematic on many other previous computers I used). Sorry, no video for now - this tablet definitely developed some blurred region on its plastic lens cover at back camera. May be I'll make some self-recording with cingg on destop later.

0001 is old 0004 patch, new 0002 should fix crash you probably saw on loading + seeking in x265-created hevc alpha encoded mp4 file I tested with 3 other hevc + alpha test files and they still worked, too I hope my change does not intro some unwanted side effect ....

Playtime with my own Slackware live DVD from 2011
by Andrew Randrianasulu 17 May '26

17 May '26

https://youtu.be/jXR1rYeOPFw Way to kill half a hour. I tried extremely downgraded virtual machine, using only qemu's TCG and not full-speed virtualization. As you can see, even at those speeds as long as file remained in ramdisk it was possible to get some slideshow out of real world clips from my old Nokia or one I downloaded from Internet waaay back. https://disk.yandex.ru/d/7Y1MPn9TTPzFiA 1.6 gb iso image I also booted it on my current machine, and even single-threaded h264 decoding in old Cinelerra-CV was able to keep up with 1600x900 60 fps screen recording from my laptop :) I manually updated kernel due to all those recent vulnerabilities found in it, and decided to entertain myself offline a bit while I was loading my machine to see if new kernel was good enough. Inside old ISO kernel 2.6.37, compiled with KVM but without some isa network card drivers, so it worked in qemu with e1000 default network card, but not in PCem with ISA based ne2k. 86Box should have PCI variant of it. I think older, quicktime-for-linux-based Cinelerra really mostly was geared towards uncompressed video - it plays so much nicer if you can waste 25 mb/s per 640x480 clip in otherwise very restricted environment :) Feel free to skip this email, it just me fooling around with toys

Fix for crash on non-existent cms profile, x265 i586 compile fix
by Andrew Randrianasulu 16 May '26

16 May '26

Andrea, you were right In my chroot launching cin with cms enabled and pointing CIN_CM_PROFILE at non-existent profile created crash! I think I fixed this one by only applying transform if it was created successfully. Please retest and provide full terminal output I also tested my x265 4.2 patch for compiling on i586 on x86-64 where it seems to work? Attached whole series I have applied at the moment git format-patch -o /dev/shm/x265_upd_2 5d80a9c9723f618b135b5721d5b413198cb442e4 /dev/shm/x265_upd_2/0001-Add-two-patches-for-decoding-hevc-alpha.patch /dev/shm/x265_upd_2/0002-Add-combined-hevc-alpha-decoding-patch.patch /dev/shm/x265_upd_2/0003-Add-simple-hevc-alpha-encode-profile-with-hvc1-tag.patch /dev/shm/x265_upd_2/0004-Fix-h265_alpha-profile.patch /dev/shm/x265_upd_2/0005-Guard-against-failed-hTransform-in-newly-added-cms-c.patch /dev/shm/x265_upd_2/0006-Fix-x265-4.2-build-on-i586.patch

hevc qsv alpha encoding patchest from 2024
by Andrew Randrianasulu 16 May '26

16 May '26

https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2024-September/333791.html I think it should be applicable to ffmpeg from around that time, but we mostly interested in first patch (for testing) Idea is to patch ffmpeg checkout from ~sept 2024 with first path named libavcodec/qsvenc: enable Alpha Encode for HEVC and try provided command line: ffmpeg.exe -v verbose -hwaccel qsv -hwaccel_output_format qsv -f rawvideo \ -pix_fmt bgra -s:v 1920x1080 -r:v 25 -i input.argb -vf \ 'format=bgra,hwupload=extra_hw_frames=120' -an -c:v hevc_qsv \ -alpha_encode 1 -y out.mp4 I guess developer was on Windows ....

I see no cms crash in cingg?
by Andrew Randrianasulu 16 May '26

16 May '26

Using lcms2-2.19.1-i686-1 CIN_CM_PROFILE="/usr/share/color/icc/colord/sRGB.icc" bin/cin ~/prophot_srgb/gradient\ ProPhoto.jpg ~/prophot_srgb/gradient\ sRGB.jpg or CIN_CM_PROFILE="/usr/share/color/icc/colord/WideGamutRGB.icc" bin/cin ~/prophot_srgb/gradient\ ProPhoto.jpg ~/prophot_srgb/gradient\ sRGB.jpg it loads/plays without crashing for me ... Andrea, can you send me profile that crashes cingg with those params ?
