respin of libaom build options patch to use NASM
by Andrew Randrianasulu 14 Apr '26

14 Apr '26

I tested it on ubuntu 16.04 + updated nasm and it seems to build fine (with libaom 3.8.0) Dear Phyllis, can you test it again? I hope it will work in other cases too (this is supported option, after all), and you (and anyone else) will able to build cingg on old Ubuntu out of the box.

patch adding termux to bld_prepare.sh script
by Andrew Randrianasulu 14 Apr '26

14 Apr '26

LOR user asked for this. I briefly tested it by running "./blds/bld_prepare.sh termux" on aarch64 termux but because all important packages were already installed it did nothing but printed them all.

Cinelerra-GG git repository and snapshots
by Igor BEGHETTO 11 Apr '26

11 Apr '26

Time ago, for what I remember, was possible to download a snapshot from Cinelerra-gg git repository. Now I don't see aymore that feature. It was useful for those user who didn't want to use the "pull" capabilities of Git. Would it be possible to restore this feature? Thanks!

OT: Blackmagic_HyperDeck_Windows Setup for Shuttle SSDphic Disk Recorder
by Terje J. Hanssen 06 Apr '26

06 Apr '26

My camcorder since 2007, Sony HDR-FX7E has a quality lens Carl Zeiss 20x optical zoom and attachments. It is a 1080i50 HDV camcorder that records 1440x1080 anamorphic 4:2:0 MPEG-2 compressed 8-bit video on mini (H)DV tape cassettes. However it has Firewire and HDMI out ports to optional record at higher quality on disk recorders or via capture cards. To extend the HDV camcorder's lifespan, I bought in 2013 a Blackmagic HyperDeck Shuttle 2 portable SSD Disk recorder with HDMI and SDI in/out. I did just record a few test clips with 10-bit FHD 1920x1080 uncompressed.mov and ProRes 422 HQ codecs. https://tinyurl.com/3ncr6m5v The issue is now that the EOL and EOS HyperDeck Shuttle 2 seemingly is locked by a DNxHD bug similar like it had in 2016, and doesn't recognize any Video input. https://tinyurl.com/3fetrkp5 I did preserve a copy of the last 2015 version of the Blackmagic_HyperDeck Setup utility for Shuttle 2, but which unhappily is a Windows program. I read that Wine isn't good for low-level usb communication as needed. https://tinyurl.com/2uvv7d86 -rw-rw-r--. 1 terje terje 253841408 okt. 7 2015 HyperDeck_4.4.1.msi Do we have other easier options on Linux that can run the setup via usb, beyond borrowing a Windows PC?

autoconf 2.73 defaults to c23, possibly breaks us
by Andrew Randrianasulu 05 Apr '26

05 Apr '26

I was rebuilding on Termux and noted that mjpegtools and possibly liba52 now fails to build. Ah, I thought it was due to clang update, but apparently autoconf can cause this, when paired with c23 defaulting compiler https://www.mail-archive.com/info-gnu@gnu.org/msg03513.html === AC_PROG_CC now prefers C23 if available. Older code may need to be updated, as C23 has removed old-style (K&R) function definitions and declarations, now uses type-generic functions for strchr and similar functions, and has new keywords alignas, alignof, bool, constexpr, false, nullptr, static_assert, thread_local, true, typeof, typeof_unqual. ==== I'll try to prepare patch as my tablet charge back (after just less than 4 years of use it hardly compiles half of full cingg build .... even if plugged in!) not for this month's release, we already hit enough surprises for last-minute build changes like this.

FFmpeg 8.1 now in new AppImages
by Phyllis Smith 04 Apr '26

04 Apr '26

The latest AppImages include FFmpeg 8.1 (updated from 8.0) and dav1d updated from 0.5.1 to 1.5.3. Note that an updated version of nasm at 2.15.05 is needed for FFmpeg if doing your own builds (more about this later). Preferably use the packages that are always up to date with Git by Andrey at: https://github.com/einhander/cin-gg-packages/releases ********** Release Notes for 03/31/2026 are below ************ GIT for Cinelerra-GG has the following changes from 03/01/2026-03/31/2026 *Website ongoing improvements by Sam:* - Major security improvements were added preventing compromising the website; as well as the addition of multiple guards and checks saving time from having to handle spam that arrives in the Forum and Mailing list or impacts GIT cloning. - Mantis Bug Tracker was modified to allow for anonymous user login in order to be able to read the items without being able to add spam. *FFmpeg* updated from version 8.0 to 8.1 with our 13 patches tested/verified by Andrew. Several text files updated: downloads.txt, info/plugins.txt, and ffmpeg/plugin.opts. *Andrew-R* work: - Minor fix to correct usage of “use direct x11 for render if possible” for older16 integer formats. - Fixes to formats ffv1_vulkan.mov, h264_vaapi.mp4, prores_4444xq.pro, prores_4444.pro, and created new prores_vulkan.pro. - Additional patch2 for x264 to “fix ppc64* pink artefacting and not passing test suite for Altivec optimizations – fix sad_x4 and adjust chroma shift – as provided by videolan team. - Fix added for building libaom 3.8.0 with older versions to continue support for Ubuntu 16. The patch removes some warning flag add and switched to using in-tree nasm. It is not for sure an acceptable solution so more testing and reporting of any anomalies would be useful. This may be backed out in the future as updating Nasm and Cmake may be a more usable solution. - Dav1d updated from 0.5.1 to 1.5.3 with a non-trivial patch to use cmake instead of their meson. - X265 compile for multibit now uses multiple cpus when available so that total compile time can be cut a few minutes (sometimes 21 minutes on a Ryzen 7 with 16 cpus instead of 43). *Manual* updates: - Additional “Tip” for taking advantage of a computer’s multiple gpus was provided by *Terje* and nicely Latex formatted by *Andrea*. - New section added to explain more about AppImages as prompted by Terje’s questions.

Possibility of copying release date version of Andrey's rpm?
by Phyllis Smith 04 Apr '26

04 Apr '26

Question for Andrey: The RPM packages at : https://github.com/einhander/cin-gg-packages/releases are much appreciated - with the compilation happening every time there is a GIT checkin - thus providing an early check that CinGG still compiles successfully on the various Debian, Suse, Fedora, and Ubuntu operating systems + the opportunity for users to download the packages to ensure no fallout from possible errors in code changes. Question: would Andrey have any concerns about the possibility of me downloading the RPMs ONLY on the latest versions that match the AppImage? (i.e. not every GIT change) and putting that tagged release on the CinGG website every month? This would just be for an extra source location for users. The current tars and pkgs folders on the website are still from 10/31/2020 at ffmpeg 4.3, really should not be used, and it does not look like I will ever be able to resurrect the Xen monthly builds of those files or update all of the operating systems involved. "NO" is a perfectly acceptable answer and Andrey can reply directly to just me if preferable - phylsmith2017(a)gmail.com . In the future, there may be other related requests!!
