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...

Two patches from Andrea's testing
by Andrew Randrianasulu 26 Nov '23

26 Nov '23

src: https://www.cinelerra-gg.org/bugtracker/view.php?id=646 ===== I made two customizations: "--disable-doc" to keep the build from crashing is adding "AC_CONFIG_MACRO_DIRS([m4])" in configure.ac otherwise autogen.sh doesn't work. The second one has been years in the making. ==== I just re-run autogen.sh after first patch, second one is untested yet (need full rebuild for this, rn I have shared (system) ffmpeg build for recompilation speeeeed.

Interesting bit they show screenshot of cinelerra-gg (I guess due to icons and ffmpeg button) yet link leads to Adam's CinHV site :) http://lmahd.com/ https://web.archive.org/web/20230124225956/http://www.lmahd.com/ it was interesting trip down to memory line ..... I wonder how exactly their sdi drivers worked, back in 2001 or so ... die to v4l limitations. Custom extension? https://web.archive.org/web/20011029181742/http://www.linuxmediaarts.com:80…

Cin-GG version to follow FFmpeg version?
by Terje J. Hanssen 21 Nov '23

21 Nov '23

.Hi Cin-GG 5.1 has been out quit a while. Currently Cin-GG happends to have the same version 5.1 as her current FFmpeg version base? Just my thought without much thinking what it implies beyond documentation updates: Because FFmpeg is a major part of Cin-GG, would it be beneficial beyond informative to let Cin-GG version follow her FFmeg base version; like version 6.1 next?

does swscale support rgbf32 conversions?
by Andrew Randrianasulu 21 Nov '23

21 Nov '23

I am trying to add fp32 tiff reading via ffmpeg for cinelerra-gg. we have this routine: convert_ctx = sws_getCachedContext(convert_ctx, ip->width, ip->height, pix_fmt, frame->get_w(), frame->get_h(), ofmt, SWS_POINT, NULL, NULL, NULL); if( !convert_ctx ) { fprintf(stderr, "FFVideoConvert::convert_picture_frame:" " sws_getCachedContext() failed\n"); fprintf(stderr, "pix_fmt %s \n", av_get_pix_fmt_name(pix_fmt)); fprintf(stderr, "output format %s \n", av_get_pix_fmt_name(ofmt)); return -1; } so for rgbaf32 tiff it prints: FFMPEG::open_decoder: some stream have bad times: /data/data/com.termux/files/home/test_color.tif FFMPEG::open_decoder: some stream have bad times: /data/data/com.termux/files/home/test_color.tif FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgbaf32le FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgbf32le for rgba-float pipeline, or FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgba for rgba-8 pipeline. tiff images from https://github.com/imageio/imageio/files/7697625/TestImages_float32_Photosh… our ffmpeg.C http://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerra… I just added mappings to case BC_RGBA_FLOAT: return AV_PIX_FMT_RGBAF32LE; and from libavcodec case AV_PIX_FMT_RGBAF32LE: return BC_RGBA_FLOAT; did I miss something in setup parameters for this format?
