our opencv archive errors out on gcc 13 distros
by Andrew Randrianasulu 06 Dec '23

06 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.

06 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

hardware vectoroscope

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.

FreeBSD 14.0 fixes
by Andrew Randrianasulu 27 Nov '23

27 Nov '23

Hopefully they does not break anything else! I run freebsd-update directly from 13.0 to 14.0 and of course was bitten by update bug! :) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=273661 but now build seems to be ok, next is runtime testing .. PS: 5 Gb is way too small space for modern system, I need to delete few caches, all docs, and even llvm's *.a files :/

NetBSD 9.2 update to ffmpeg6
by Andrew Randrianasulu 26 Nov '23

26 Nov '23

It seems to work after I did "pkgin update /pkgin upgrade" inside NetBSD vm. I need to switch my .profile to ffmpeg6 instead of ffmpeg4 (otherwise it can't find libs) but apart from that it was working... https://mail-index.netbsd.org/pkgsrc-users/2023/06/28/msg037563.html "Announcing the pkgsrc-2023Q2 branch" In theory old ffmpeg4 still around, but I found at least on Slackware shared ffmpeg 4.4 build was crashing on fftestsrc plugin in rgba-float mode. It works with internal 6.1 I guess ffmpeg 6 will be moved to 6.1 in pkgsrc at some point but we ready for that, hopefully. I'll retest periodically....

Internal engine and ffmpeg
by Andrea paz 26 Nov '23

26 Nov '23

I continue here what we started in MantiBT #646 since my problems are not with the issue. I tried making a build that uses system ffmpeg instead of CinGG's internal one. The behavior is the usual, even though the internal engine for exr is active, ffmpeg is used. The result is the same: clipped exr images except one. Maybe I am doing something wrong in the copy/paste I do during compilation? I report the exact steps (not from root): git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5 cd /home/paz/cinelerra5/cinelerra-5.1 [patching here] ./autogen.sh ./configure --with-single-user --with-config-dir=/home/paz/.bcast6 --with-booby ### .bcast5 is for appimage make 2>&1 | tee /tmp/cin5.log && make install mv Makefile Makefile.cfg cp Makefile.devel Makefile (Curiosity: what are the last 2 steps for?) Do you guys have any improvements to propose to this set of steps? If these steps are correct then I can only think that it is Arch, although I don't see how...
