Patch: build fixes for FreeBSD 15.0
by Andrew Randrianasulu 23 May '26

23 May '26

I decided to try new BSD and of course something changed since last time I tried, spend some time troubleshooting configure script, turned out echo as built in and echo as /bin/echo behave differently! So I hope I fixed our scripts without breaking Linuxes. I patched cingg on Termux and there configure appeared and worked.

Tested nvenc profile on GT 710, it works.
by Andrew Randrianasulu 21 May '26

21 May '26

Hello all. I *finally* hauled home another desktop bought second hand, and installed my "old" GeForce 710 in it. Installed some version of Slackel ( Slackware -current from nov 2023) on it, and partially updated it. Installed proprietary 470 drivers from Slackbuilds.org link (280 mb!). There was not enough headers to compile this driver, so I compiled kernel first with its embedded config (modprobe configs, zcat /proc/config.gz > .config, make in Linux source tree). After around two hours on this Sandybridge -era i5 at 3.19Ghz + 4gb ram + mechanical 250 gb sata drive formatted as ext4 I got my kernel and proprietary driver installed, escaped world of 640*480 into my glorious 1400*900 native resolution. Compiled cingg from git, in around 45 minutes. Loaded few videos I downloaded from samples.mplayerhq.hu, tried h264 nvenc (I was careful to replace ffnvheaders with our old 2020 version, thankfully provided in tree.) At first it was failing at 97%, but then I realized all failing vids set cingg correctly to interlaced mode, as they were interlaced. Progressive 720p 60 fps mpeg2 dreamtime.mpg from HDTV folder played ok, and encoded with nvenc at around 73 fps. So, new toy is a bit noisy and can heat up to 85 C under full load, but now I hopefully can test for regressions on this front again. Also compiled qemu from git (it worked) and cinelerra-cv from my fork at github (Randrianasulu/cinelerra-cv-randrik, branch "wip"). Its mpeg decoder worked when compiled on older glibc 2.30+ gcc 5.5.0 based Slackware, but crashed under Debian 11 (glibc 2.31,gcc 10.something) and this not completely current -current Slackware with gcc 13.2.0 . I tried to debug this, but no success so far. Otherwise it works, mostly on pre-converted to mjpeg + pcm .mov files with help of modern ffmpeg. At some point I'll manually switch my keyboard, mouse and monitor back to main machine, they both know how to "sleep" properly, so I can leave them in such state and wake up from keyboard (this function was problematic on many other previous computers I used). Sorry, no video for now - this tablet definitely developed some blurred region on its plastic lens cover at back camera. May be I'll make some self-recording with cingg on destop later.

0001 is old 0004 patch, new 0002 should fix crash you probably saw on loading + seeking in x265-created hevc alpha encoded mp4 file I tested with 3 other hevc + alpha test files and they still worked, too I hope my change does not intro some unwanted side effect ....

Playtime with my own Slackware live DVD from 2011
by Andrew Randrianasulu 17 May '26

17 May '26

https://youtu.be/jXR1rYeOPFw Way to kill half a hour. I tried extremely downgraded virtual machine, using only qemu's TCG and not full-speed virtualization. As you can see, even at those speeds as long as file remained in ramdisk it was possible to get some slideshow out of real world clips from my old Nokia or one I downloaded from Internet waaay back. https://disk.yandex.ru/d/7Y1MPn9TTPzFiA 1.6 gb iso image I also booted it on my current machine, and even single-threaded h264 decoding in old Cinelerra-CV was able to keep up with 1600x900 60 fps screen recording from my laptop :) I manually updated kernel due to all those recent vulnerabilities found in it, and decided to entertain myself offline a bit while I was loading my machine to see if new kernel was good enough. Inside old ISO kernel 2.6.37, compiled with KVM but without some isa network card drivers, so it worked in qemu with e1000 default network card, but not in PCem with ISA based ne2k. 86Box should have PCI variant of it. I think older, quicktime-for-linux-based Cinelerra really mostly was geared towards uncompressed video - it plays so much nicer if you can waste 25 mb/s per 640x480 clip in otherwise very restricted environment :) Feel free to skip this email, it just me fooling around with toys

Fix for crash on non-existent cms profile, x265 i586 compile fix
by Andrew Randrianasulu 16 May '26

16 May '26

Andrea, you were right In my chroot launching cin with cms enabled and pointing CIN_CM_PROFILE at non-existent profile created crash! I think I fixed this one by only applying transform if it was created successfully. Please retest and provide full terminal output I also tested my x265 4.2 patch for compiling on i586 on x86-64 where it seems to work? Attached whole series I have applied at the moment git format-patch -o /dev/shm/x265_upd_2 5d80a9c9723f618b135b5721d5b413198cb442e4 /dev/shm/x265_upd_2/0001-Add-two-patches-for-decoding-hevc-alpha.patch /dev/shm/x265_upd_2/0002-Add-combined-hevc-alpha-decoding-patch.patch /dev/shm/x265_upd_2/0003-Add-simple-hevc-alpha-encode-profile-with-hvc1-tag.patch /dev/shm/x265_upd_2/0004-Fix-h265_alpha-profile.patch /dev/shm/x265_upd_2/0005-Guard-against-failed-hTransform-in-newly-added-cms-c.patch /dev/shm/x265_upd_2/0006-Fix-x265-4.2-build-on-i586.patch

hevc qsv alpha encoding patchest from 2024
by Andrew Randrianasulu 16 May '26

16 May '26

https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2024-September/333791.html I think it should be applicable to ffmpeg from around that time, but we mostly interested in first patch (for testing) Idea is to patch ffmpeg checkout from ~sept 2024 with first path named libavcodec/qsvenc: enable Alpha Encode for HEVC and try provided command line: ffmpeg.exe -v verbose -hwaccel qsv -hwaccel_output_format qsv -f rawvideo \ -pix_fmt bgra -s:v 1920x1080 -r:v 25 -i input.argb -vf \ 'format=bgra,hwupload=extra_hw_frames=120' -an -c:v hevc_qsv \ -alpha_encode 1 -y out.mp4 I guess developer was on Windows ....

I see no cms crash in cingg?
by Andrew Randrianasulu 16 May '26

16 May '26

Using lcms2-2.19.1-i686-1 CIN_CM_PROFILE="/usr/share/color/icc/colord/sRGB.icc" bin/cin ~/prophot_srgb/gradient\ ProPhoto.jpg ~/prophot_srgb/gradient\ sRGB.jpg or CIN_CM_PROFILE="/usr/share/color/icc/colord/WideGamutRGB.icc" bin/cin ~/prophot_srgb/gradient\ ProPhoto.jpg ~/prophot_srgb/gradient\ sRGB.jpg it loads/plays without crashing for me ... Andrea, can you send me profile that crashes cingg with those params ?

x265 4.2 build error on i586, possible patch
by Andrew Randrianasulu 15 May '26

15 May '26

I ran into error: ELF format cannot produce non-PC-relative PLT references by trying to build full cingg on i586 Slackware. Sorry my bad for not doing this earlier I think I isolated problem to attached patch, but I did not test it yet on i586 or x86-64 it only compile tested x265 [info]: HEVC encoder version 4.2+1-e444744 x265 [info]: build info [Linux][GCC 11.2.0][32 bit] 8bit+10bit+12bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX XOP FMA4 FMA3 BMI1 x265 [info]: Main profile, Level-3 (Main tier) x265 [info]: Thread pool created using 4 threads ok, I think it works on i586

ChromaKey(Avid) on manual
by Andrea paz 15 May '26

15 May '26

I discovered that in the description of the ChromaKey (Avid) plugin in the manual, I left in some lines that refer to the ChromaKey (HSV) plugin. This mistake of mine makes the description confusing and makes it difficult to understand how the plugin works. I have removed the incorrect sentences and made a few minor adjustments. I apologize for the error and for discovering it so late. Here is the link to download the corrected LaTeX file. https://limewire.com/d/MiMBE#nAmC98NvCL
