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!!

ffmpeg 8.1 with SVT-JPEG-XS support
by Terje J. Hanssen 01 Apr '26

01 Apr '26

The new, standard JPEG-XS codec support in ffmpeg 8.1 --enable-libsvtjpegxs seems to have gone a bit under the radar. JPEG-XS is high-lighted as a lightweight image and video compression standard (ISO/IEC 21122) designed specifically for applications requiring high visual quality, ultra-low latency, and low computational complexity. Unlike standard compression formats (like HEVC or JPEG) that focus on maximum compression ratio, JPEG-XS prioritizes keeping content "visually lossless" while reducing bandwidth, making it ideal for professional video production, IP transport, and real-time streaming. JPEG-XS providing compression ratios up to 10:1 while maintaining high video quality. The codestreams can be encapsulated in several standard container formats to allow for transportation and storage: MXF, MPEG-2 (MPEG-TS), MP4, HEIF and more. https://www.phoronix.com/news/FFmpeg-Merges-JPEG-XS https://github.com/OpenVisualCloud/SVT-JPEG-XS https://openbenchmarking.org/test/pts/svt-jpeg-xs

Integrate nasm 2.15.05
by Andrew Randrianasulu 29 Mar '26

29 Mar '26

More experimental patch, but I tested it on Rosa 2016 with renamed /usr/bin/nasm to _nasm, and build finished, and av1 video test decoded ok do not forgot to put actual tar.xz in thirdparty/src while testing this

Possible fix for parallel x265 multilib build
by Andrew Randrianasulu 27 Mar '26

27 Mar '26

After reading https://flameeyes.blog/2010/10/18/tell-tale-signs-that-your-makefile-is-bro… I tried to modify our multilib.sh script, and apparently just adding "-j" to make commands made them run nasm jobs on all cores (as defined in previous makefile) Try attached patch and see if it improves build times without breaking build

codespell page for cingg
by Andrew Randrianasulu 26 Mar '26

26 Mar '26

It was send to me some time ago but whole fossies.org is not reachable w/o vpn here, so I only now checked this page. https://fossies.org/linux/misc/cin_5.1.20260228-src.tgz/codespell.html Some of it might be false positive (in sense some words just funnier if you bend them a bit? ;) ) but some might be worth correcting. Probably for next months ...

Possible fix for libaom 3.8.0 on ubuntu 16.04 x86-64 LTS
by Andrew Randrianasulu 22 Mar '26

22 Mar '26

It was failing to build, but I patched out some hopefully not really needed warning flag add, and switched it to in-tree nasm I am not sure if switching it to nasm in general good or bad idea. We can add this patch next month, if you want to test it more
