Integrate nasm 2.15.05
by Andrew Randrianasulu 28 Mar '26

28 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 ...

ffmpeg 8.1 with SVT-JPEG-XS support
by Terje J. Hanssen 24 Mar '26

24 Mar '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

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

question about prores_4444xq.pro
by Andrew Randrianasulu 22 Mar '26

22 Mar '26

For now it reads, if my copy is correct: cat bin/ffmpeg/video/prores_4444xq.pro mov prores_ks # ProRes, encoder prores_ks. Container Apple QuickTime movie (.mov). #Support for alpha channel profile=5 quant_mat=auto cin_pix_fmt=yuv444p10le #also gbrp10le # The possible video profile values for the ProRes codec are: # 5 = 4444xq # 4 = 4444 # 3 = HQ (high quality) # 2 = Standard # 1 = LT (light) # 0 = Proxy ===== but shouldn't line cin_pix_fmt=yuv444p10le reads like in prores_4444.pro cat bin/ffmpeg/video/prores_4444.pro mov prores_ks # ProRes, encoder prores_ks. Container Apple QuickTime movie (.mov). # Support for aplpha channel profile=4 quant_mat=auto cin_pix_fmt=yuva444p10le #also gbrp10le # The possible video profile values for the ProRes codec are: # 5 = 4444xq # 4 = 4444 # 3 = HQ (high quality) # 2 = Standard # 1 = LT (light) # 0 = Proxy Note that it uses yuv*A*444p, not just yuv444p ! Oh, and aplpha word was underlined with red wavy line in gmail editor - typo detected! currently playing with ffmpeg.git and this merge request: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/22418#issuecomment-32848 it seems that new Vulkan encoder can do 12bit even with alpha. But for some reason it works inside cingg but not with ffmpeg standalone! Note that this merge request does not work for me fully (unlike vanilla ffmpeg.git at 9c63742425aa9c84148f218513f74dbab1e01926) even in cingg, or more accurately it makes encoded video with some block artefacts/colored lines. Not for full footage, but for some parts of it.

Some film grain settings for ffmpeg noise filter
by info＠bandshed.net 21 Mar '26

21 Mar '26

Lol, I just realized I had sent this to the old Cinelerra list...oops! Maybe this has been covered here or on the forum but on a recent project with some old concert footage I wanted to add some film grain but the 'Aging TV' built-in effect is kind of too much and it also drives the encoder bits wild and make huge file sizes so I did a bit of googling on the ffmpeg noise filters and I found something that works pretty well so I thought I'd share.. https://bandshed.net/images/screenshots/shot-2026-03-21_14-37-53.jpg So going from the picture the main thing is using only the luma color "c0" channel because grain is not comprised of colors from all channels. And in the c0_flags field I used 't+u' to make the grain temporal and change with the frames more realistically. Anyway to be honest I haven't messed in-depth with very many ffmpeg filters so I was very happy to find a good grain option in Cin.. Best, Glen --

Vulkan video in qemu
by Andrew Randrianasulu 21 Mar '26

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 ...
