article about making flatpack

https://opensource.com/article/19/10/how-build-flatpak-packaging conceptually sounds nearly simple enough to try (because Cin usually builds statically), but sandboxing might give some surprizes....

extreme offtopic, but: apparently only one video editor for Atari!
by Andrew Randrianasulu 05 Nov '21

05 Nov '21

Mac was famous for first professional (avid/1) and consumer (Adobe Premiere) NLEs, Amiga was famous for specialized video editing hardware (Video Toaster) or whole new clone (Draco), but apparently even Atari (also m68k based computer) had some promising program in late 90x? https://vanel.net/tntmag/mounta12.htm {author seems to be French, so most up to date info in fr??} You probably can try to lauch this in hatari (atari emulator) running EmuTOS? No support for audio, and as you can guess from screenshot only some cinepack quicktime videos will work as input (not counting more obscure animation formats) But might be fun to poke in your free time (if you have such thing! I seriously hope you have!)

libaom 3.2.0
by Andrew Randrianasulu 01 Nov '21

01 Nov '21

https://aomedia.googlesource.com/aom/+/refs/tags/v3.2.0/CHANGELOG --- This release includes compression efficiency and perceptual quality improvements, speedup and memory optimizations, as well as some new features. - New Features * Introduced speeds 7, 8, and 9 for all intra mode. * Introduced speed 10 for real time mode. * Introduced an API that allows external partition decisions. * SVC: added support for compound prediction. * SVC: added support for fixed SVC modes. - Compression Efficiency Improvements * Intra-mode search improvement. * Improved real time (RT) mode BDrate savings by ~5% (RT speed 5) and ~12% (RT speed 6). The improvement was measured on the video conference set. * Improved real time mode for nonrd path (speed 7, 8, 9): BDrate gains of ~3-5%. * Rate control and RD adjustments based on ML research in VP9. Gains of ~0.5-1.0% for HD. - Perceptual Quality Improvements * Added a new mode --deltaq-mode=3 to improve perceptual quality based on a differential contrast model for still images. * Added a new mode –deltaq-mode=4 to improve perceptual quality based on user rated cq_level data set for still images. * Weighting of some intra mode and partition size choices to better manage and retain texture. - Speedup and Memory Optimizations * Further improved 2-pass good quality encoder speed: o Speed 2 speedup: 18% o Speed 3 speedup: 22% o Speed 4 speedup: 37% o Speed 5 speedup: 30% o Speed 6 speedup: 20% * Optimized the real time encoder (measured on the video conference set): o RT speed 5 speedup: 110% o RT speed 6 speedup: 77% - Bug Fixes * Issue 3069: Fix one-pass mode keyframe placement off-by-one error. * Issue 3156: Fix a bug in av1_quantize_lp AVX2 optimization. --- I quickly re-packed .tar.gz into xz and renamed libaom patches accordingly. It seems to work with ffmpeg-4.4. Phyllis, can you test (may be next month?) if libaom-3.2.0 still works on both new and old distros (as you use them for appimage build)? Also, ffmpeg 4.4.1 was released - mostly bugfixes from fuzzers, it seems, but also few changes in util https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/7e0d640edf6c3eee1816b105c2f74… https://git.ffmpeg.org/gitweb/ffmpeg.git/tag/2aa4f5cc8be5e3168191cd13a61178…

New presets for DNxHR in mxf
by Andrea paz 27 Oct '21

27 Oct '21

I thought about implementing the various DNxHRs in the mxf format, which is their natural format (Andrew had already started with the proxy). Those already present as mov can be left or removed; I would leave them.

Run And Integrate Cinelerra AppImage With AppImageLauncher
by Terje J. Hanssen 23 Oct '21

23 Oct '21

The README appimage file describes the CLI method to install Cinelerra-GG 1) download AppImage file move from Download folder to your preference 2) make it executable chmod u+x {AppImageFile name} 3) run it ./cinelerraGG.AppImpage -------------------------------- Now I have also tried the /GUI method/ to download, Run And Integrate Cinelerra AppImage with installed *AppImageLauncher*. On openSUSE Leap 15.3 (and surely similar on other distros) AppImageLauncher is integrated with Firefox as follows: 1) start download the AppImage file, and a widget popup in Firefox with the option to open it with AppImageLauncher (instead of Saving it) 2) At the end of the download a new popup asks to integrate it with your desktop system. OK -------------------------------- (The AppImage installation directory is /home/user/Application by default, but can be customized in the Launcher widget) That's it. Both *Cin* and *Cin-multi* were installed this way, automatic integrated with icons and in the app-menue in Gnome, see the attached screenshot AppImage.png and urls to articles for detailed info below. I have used *alacarte* to add the icon comment sub-text to *Cin-multi* for multiple bit version.the icon, as also mentioned in a previous post AppImage and Desktop Integration with an app launcher https://www.mail-archive.com/[email protected]/msg02692.html Packages I installed first on Leap 15.3 zypper se -is appimage Loading repository data...

opencl accelerated dcraw

from Imagemagick sources.. https://github.com/ImageMagick/dcraw/commit/00d7d612efb84e27e465a7fbeca355e… but you can try latest (dcraw 9.28) commit from this repo.. in theory it might make cingg's raw decoding a bit faster on opencl-capable gpu... only performace claim I found was "With an OpenCL version of dcraw.c converting an 6034x4012 NEF file to JPEG takes 4.7 seconds instead of 13.8 seconds on my machine. 1:05 AM · 25 мая 2016 г.·" - https://mobile.twitter.com/MagickNET/status/735230384615661568

Playing catchup with randrik12 patches
by Phyllis Smith 17 Oct '21

17 Oct '21

Andrew, when I add the following line to ...thirdparty/Makefile, it errors out pretty much right away: opus.cfg_vars?= --disable-extra-programs This is in randrik12/0052-fix-opus-configure.patch and it would be nice to have this to save a little time.

offtopic: Digitize and record Video with A/D USB adapters
by Terje J. Hanssen 14 Oct '21

14 Oct '21

Although I have and have used some Black Magic external tools for this, I'm also interested in simple and low cost options for Linux workstations. In a recent article the Augustin VGB100 usb2.0 video adaper and VLC was used to record video https://www.arsouyes.org/en/blog/2021/2021-05-17_Numerisation_VHS Any experience here with similar A/D video adapters, quality and applications for recording on Linux?. Second I wonder if some lossless, compressed master video format is available for better quality before final converting with typical ffmeg? And third, maybe a stupid question: Is it possible to record just Audio with an A/D Video adapter, which audio record format and what quality, compared with a pure Audio adapter? And if so, can audio record applications like Audiacity be used? Terje
