SVT-AV1 works on i586, but slowly.
by Andrew Randrianasulu 14 Dec '23

14 Dec '23

Installed SVT-AV1 1.5.0 from Slackbuilds on my Slackware 15.0 i586 it works, but at around 0.8 fps for 720p video ffmpeg -i MLP_animation_sleepsong_IeIDCNS-VUw.webm -s 1280x720 -an -f yuv4mpegpipe - | SvtAv1EncApp -i - -b mlp.ivf --passes 1 --rc 1 --tbr 1000 after looking at code I see all asm there is 64bit :) this explains why it is much faster on x86_64. Anyway, even 0.8 fps is ok for short (few mins) clips, I guess.

News and enhancements with CinGG/FFmpeg 6.1 ?
by Terje J. Hanssen 12 Dec '23

12 Dec '23

I am wondering if the news and enhancements of importance to CinGG/FFmpeg 6.1 users may be outlined, including what is ready now and expected upcoming next? Something listed last month by Andrew in "ffmpeg 6.1 is out!" and by Phyllis in "GIT... CinGG changes >.FFmpeg 6.1 upgrade from 5.1. ." as the News November 10th, 2023, FFmpeg 6.1 "Heaviside" http://ffmpeg.org/index.html#news ------- For example while the AV1 codec was mentioned available for CinGG already in February News 2019 https://www.cinelerra-gg.org/news-updates/february-news-for-release-av1-and… AV1 looks to be an even more important improvement with FFmpeg 6.0 and 6.1, according to some selected articles below: FFmpeg 6.0 Will Be Big With AV1 Hardware Decoding, Many Other Features https://www.phoronix.com/news/FFmpeg-6.0-FOSDEM-2023 FFmpeg 6.1 Introduces AV1 Codec Integration https://www.free-codecs.com/news/ffmpeg_6_1_introduces_av1_codec_integratio… AV1 vs. HEVC: The Codec Showdown https://www.gumlet.com/learn/av1-vs-hevc/ AV1 vs. HEVC: The Codec Showdown https://www.gumlet.com/learn/av1-vs-hevc/ Terje J.

Limit number of opencv modules we build
by Andrew Randrianasulu 10 Dec '23

10 Dec '23

Hopefully I get them right! Builds with opencv4 (2020 tarball) on Slackware -current x86_64 hopefully will make compile farm's job a bit easier. Note, I only modded and tested local static build, you can try to add similar line (with closing "\" !) to second, dynamic case in opencv_build file in root of cingg source tree.

GIT checkin to include better description
by Phyllis Smith 10 Dec '23

10 Dec '23

Checked into GIT and hopefully Andrew thinks the description is more relevant there (if not, please let me know). 1. Fix freebsd 14 build, moved to python39 switch from ffmpeg4 to 6 fix for freebsd 14 build OpenEXR 2. Add missing includes for newest distros build tools / makeappimagetool (Andrea originally discovered) 3. Limit number of opencv modules we build (hopefully will build a little faster for now!) 4. New render formats for HDR and WBMP since now at ffmpeg 6.1. Andrew, please verify that I did not make any mistakes !! Thanks, Phyllis

our opencv archive errors out on gcc 13 distros
by Andrew Randrianasulu 05 Dec '23

05 Dec '23

so, I tried to fix it in brutal way download and unpack opencv 4.8.1 from their sf page. 98 mb or so cd into it cd opencv-opencv-7d2cb72/ mkdir build cd build cmake .. try make, it will take some time. but even if build fails we mostly interested in .cache directory. ../../../opencv-opencv-7d2cb72/.cache/ade/fa4b3e25167319cb0fa9432ef8281945-v0.1.2a.zip copy that in our unpacked archive instead of 0.1.1f download our archive from https://cinelerra-gg.org/download/opencv/opencv-20200306.tgz unpack it into DIFFERENT directory. change this file AND also search for cmake downloader and replace it with one updated from same 4.8.1 distribution modules/gapi/cmake/DownloadADE.cmake now from rootof directory where two dirs from our archive {now updated} exist you can call tar -cvzf ../opencv-20200306-f.tgz . and put this new archive into thirdparty and call configure with new file name. Hopefully it will works even on fedora 38+ Currently testing on Slakel current , but I tried to be smart and cut down build module lest, and this took few rebuilds to get right.

Fix for appimagetool build?
by Andrew Randrianasulu 05 Dec '23

05 Dec '23

I tried to build tools / makeappimagetool on Slackel 7.7.1 (Slackware -current from nov 8 2023) and run into same problem as Andrea. So, I fixed build by applying two include patches from upstream. Please test?

Cinelerra-GG packages build farm
by Андрей Спицын 05 Dec '23

05 Dec '23

Hello Phyllis and everyone, I've created a build farm for cinelerra deb and rpm packages. Although it is at an early stage of development, it can build packages on every git change in the main repo. Feel free to use these packages at https://github.com/einhander/cin-gg-packages/releases. Note that releases correspond to a build date, not a git commit date. Current build hosts are debian 12 and alma linux 8. I'm open to suggestions for a new distro and packages. Best regards, Andrey Spitsyn

A bit on collusion course with other messages, but I watched some short (19 min) fun with hardware vectoroscope. https://m.youtube.com/watch?v=VTSNqMmnUMk so now I have SOME idea how it was used ......

cinelerra-gg NetBSD and FreeBSD ports (package rules)
by Andrew Randrianasulu 29 Nov '23

29 Nov '23

so, I spend some more time trying to get packaging on BSD running. I think I have first results, while I probably need more assistance about NetBSD's options/configuration. Upgraded my 9.2 to 9.3, and also packages. some ports do not fit on my small (5 GB) virtual hdd, and netBSD also does not know NFS v4 yet, so my default mount from Slackware failed here. But I used tmp pseudo harddrive attached to netbsd VM like this qemu-system-i386 -hda netbsd-92.qcow -hdb /dev/shm/tmp_1gb_ext2 -enable-kvm -smp 2 -device ES1370 -boot c -netdev user,id=myslirp,ipv6=off -device e1000,netdev=myslirp -m 512 -cpu pentium2 and mounted it inside VM with mount -t ext2fs /dev/wd1 /mnt port for NetBSD specifically does not have OpenEXR support yet, probably I need to add some more includes. ... But basic mpeg2 file playback works.
