crash
by Andrea paz 10 Nov '21

10 Nov '21

I tried to make a build from git: the compilation happens without errors (see cin5.log), but when I start CinGG I get a crash. No dumps are formed. At the terminal I have only these lines: build ladspa plugin index for: /home/paz/cinelerra5/cinelerra-5.1/bin/ladspa MWindow::init_ladspa_plugins: can't create ladspa plugin index: /home/paz/.bcast6/ladspa_plugins._home_paz_cinelerra5_cinelerra-5.1_bin_ladspa MWindow::init_theme: prefered theme Cakewalk not found. MWindow::init_theme: theme_plugin not found. unjoined tids / owner 1 00007feefd7fa640 / 00007fef46622fc0 12BC_Clipboard I had no problems with the November 1 version.

small note on documentation
by Andrew Randrianasulu 07 Nov '21

may be page https://cinelerra-gg.org/download/CinelerraGG_Manual/Tips_Improving_Smaller… in section where it talks about speeding up ffmpeg plugins can benefit from direct link to specific section? https://cinelerra-gg.org/download/CinelerraGG_Manual/Speed_up_Ffmpeg_plugin… also, I think usual _decoding_ tricks like lowres and skiploopfilter might work in opts files? (need to doublecheck)

article about making flatpack
by Andrew Randrianasulu 06 Nov '21

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

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…
