Vulkan video in qemu
by Andrew Randrianasulu 21 Mar '26

https://gist.github.com/peppergrayxyz/fdc9042760273d137dddd3e97034385f Even more bleeding edge (in other words: it very well may cut you quite painfully) than normal Vulkan encode/decode, I guess host Intel (ANV) limitations apply ... Requires patched qemu. It sort of wild people try to game in guest Linux, in Linux-hosted Qemu VM. But well ...

OCIO filter in ffmpeg.git
by Andrew Randrianasulu 08 Mar '26

08 Mar '26

https://source.ffmpeg.org/gitweb/ffmpeg.git/commit/677cf95ea4be805fa326adb0… looks like it uses standard one input-one output, so it may even work in cinelerra-gg, if nothing else broke.. Not sure how to properly define configuration for such filter - may be Blender have some GUI for this? Random link I stumbled upon while looking at OCIO search results - some notes on digital photography, it seems? https://juraj-notes.tomori.sk/

My device not longer support vulkan capabillty
by Terje J. Hanssen 02 Mar '26

02 Mar '26

I had to re-install openSUSE Tw-Slowroll on my Dell XPS-13/9370 with i7/ UHD620 iGPU ( Intel Coffe Lake, gen8, 2017). It worked previously when I tested cin-12-02-2026-x86_64.AppImage and ffmpeg transcoding with h264_vulkan before that. The equivalent tests errors out with h264_vulkan, but works with h264_vaapi and h264_qsv Cingg ------ [h264_vulkan @ 0x7f2f462a0900] Device does not support the VK_KHR_video_maintenance1 extension!

I have verified that the same tests work on my 2 year more legacy Sky Lake with i7/ HD530 iGPU (gen6, 2015) and Slowroll. -------- So far I have not discovered possible missing package, driver or lib that cause this issue, so troubleshooting hints are welcome.

Another test appimage, hopefully this time with onevpl/vulkan/libplacebo/zimg
by Andrew Randrianasulu 01 Mar '26

01 Mar '26

https://disk.yandex.ru/d/Eqvrpylgwvc7Rw I fighted libplacebo and not sure who won - there is no Vulkan device in qemu VM! Try when you can and tell me what works? I did not include 16bpc crash fixes there, but without specifical env. variable those old new formats should not show up

Just to keep updated, made new AppImages
by Phyllis Smith 28 Feb '26

28 Feb '26

New release, just to keep updated. New AppImages are at: https://download.cinelerra-gg.org/type=appimage *Preferencially use the package* versions as provided by Andrey at: https://github.com/einhander/cin-gg-packages/releases for > Debian 13 > Debian 12 > Debian 11 > Suse Leap 15.5 > Suse Tumbleweed > Fedora 38 > Ubuntu 22.04 > *GIT for Cinelerra-GG has the following changes from 02/03/2026-02/28/2026* Testing and ongoing experimental work on *Vulkan* was being done by *Andrew, Andrea, and Terje*. Updated msg/txt to consolidate only the most noteworthy changes of 2025. As discovered by *Stefan*, libzmpeg3/video/mmx.h errs out when compiled with gcc 15 using optimization level 3. Andrew researched this and patched the fix as used by another application. *Andrew-R* work: Applied 2 patches which might fix parallel “make install” in some cases. For Termux, patch added to use remap_video_codec in decode.opts for “mediacodec” decode, patch for djbfft-0.76, and blds/termux.bld updated. Enable yuv/yuva16 and rgb/rgba16 integer formats if ALLOW_OLD_16BPC environment variable is set to any value. This modification required un-commenting previous code and fixing a couple of crashes. It is still in the experimental stage. Render formats added: - vulkan render formats for experimentation, ffv1_vulkan.mov, hevc/h264/av1_vulkan.mkv, h264_vulkan.mp4 - av1_mediacodec.mp4, magicyuv.avi, speedhq.avi Generate an error message if python/python3 versions is missing from the system and stop the build in configure.ac. In addition guicast/Makefile has been made more robust as pertains to python. Correct makeinfo/texinfo check in configure.ac. Updated bld_appimage.sh in the main directory as a result of the testing being done by Terje. Fixed error in blds/bld_prepare.sh for Arch comment and added Slowroll option to Suse, etc. option. Mods for experimental Vulkan have been added to cinelerra/ffmpeg.C. Patch needed for Rosa 2016 thirdparty/src as libtheora-1.2.0.patch0.

No nvidia testing from me, second motherboard died
by Andrew Randrianasulu 27 Feb '26

27 Feb '26

Sorry. It was working fine yesterday, but I meet cuda error while testing my appimage with old ffnvcodecs. I was rebuilding cingg when everything just hang hard. On reboot I meet Award BIOS Bootblock, instead of normal bios screen. Tried to re-flash bios from motherboard's support cd - flasher seemingly hanged, without even telling me what type of flash chip it found. Yeah, this Asus M2N SLI was from ~2007 but was working fine until yesterday .... BIOS chip is soldered, so I guess R.I.P.

hack for makeappimage for old systems
by Andrew Randrianasulu 26 Feb '26

26 Feb '26

Well, with boost 1.61 and gcc 5.5 as in Rosa2016.1 Note, I have no idea for now how it will work on new systems with new boost etc I just wanted to make appimage with old nv-codec on old system. It checks/sets cxx standard to c11, and adds liboost_system to libs, and changes constexpr to just expression as it probably was in old boost Not for inclusion , at least not until I check it on more systems

libtheora 1.2.0 fails to autoreconf on Rosa 2016.1
by Andrew Randrianasulu 26 Feb '26

26 Feb '26

It raised autoconf level to 2.71 for some reason, and thus old system failed ... I pushed it back to 2.69 and build continued .. Just patch for thirdparty/src, not git am

P010 format support for v4l2
by Andrew Randrianasulu 26 Feb '26

26 Feb '26

https://github.com/awawa-dev/HyperHDR/discussions/967 Probably not really useful with "normal" SDR sources, but might be useful for some weird loopback cases like outputting HDR via display port, capturing via capture card, connect it via usb 3.0 cable back to computer, get stream via v4l2 into application (I do not think cingg works with this specific format yet) . Or replace DP video output with some game console... Moar bits ! :)

Copy a Cin unbundled, dynamic build with 'cp -a'
by Terje J. Hanssen 24 Feb '26

24 Feb '26

For my purpose, I just used 'cp -a' to USB stick to copy my 41M unbundled, dynamic Cin bin structure from my Alder Lake build machine to a Coffee Lake desktop, both with Slowroll and ffmpeg-8. I just had to add-install three dependices libOpenEXRUtil-3_4-33, libtheora1 and libsuil-0-0, to get Cingg working on a standard Gnome desktop installation where I rendered hevc_qsv and hevc_vaapi. If the same may work or not beween more different architechtures and systems, I don't know.
