libsvtav1 as internal lib patch
by Andrew Randrianasulu 29 Dec '23

29 Dec '23

you need to repack orig tar.gz svt-av1 archive, I'll upload that separately. Disabled by default because it fails w/o patch on termux, but should be easier for users than messing up with external variables .... tar.xz of svt-av1 weighted 8.4mb but this is unavoidable considering interest in this particular encoder.

Updated x265 snapshot from another thread
by Phyllis Smith 28 Dec '23

28 Dec '23

This was from another thread - mixed in with libaom 3.8 - so wanted it to not get lost. Initial test on the x265 snapshot of 17122023 succeeded, but I have a lot more testing to do. For some reason my initial test core-dumped but when I ran it again, it worked so not sure why. (I broke more things today, then I fixed).

Well, it hard to keep me attracted for long-form video essay nowadays, but this one did the trick so far https://m.youtube.com/watch?v=YZ8Rcqb9w88 "Animal Perspective Books: A Comprehensive History of Naturalist Animal Xenofiction" 1h47m runtime ....

python3.12 venv
by Andrew Randrianasulu 20 Dec '23

20 Dec '23

Was looking for a way to set python3.12 for system or specific project. found this gist for Ubuntu under WSL2 https://gist.github.com/4sskick/19f071f0b454849b03c31d753527d86a But I hope last four lines are universal: { cd to cinelerra-gg's source root where autogen.sh is first, I think } ===== - when everything are done, ready to create venv `python3.12 -m venv venv` - do activate the virtual env `source venv/bin/activate` - check python version using on venv `python --version` - do deactivate the virutal env just type `deactivate` on root project =====

Two observations about screen recording via cingg
by Andrew Randrianasulu 20 Dec '23

20 Dec '23

So, I enabled "loopback mode" in alsamixer, set xmms (with ALSA output) to play, and tried to record both video and audio (my previous motherboard had no loopback switch for its integrated audio, so specialized .asoundrc file setting up alsa loopback module was used). When I left recording settings to their default value of input frequency = 48000 I get strange one-core cpu overload in kernel space (orange color in gkrellm). I set input frequency to 44100 and everything was working smoothly from there. I also tried to record 1440*900*24bit*30fps with cpu set to its lowest frequency of 1.4Ghz. This usually resulted in video being shorter than audio, so I slowed video down to 0.68 or so via speed curve, and clipped few last silent frames. When CPU set to performance and can revv up to 4Ghz audio and video tend to be much more aligned as long as their lenght is concerned. codec was mjpeg444 / s16le into mov container on tmpfs. So I guess especially for screencapture on slow CPU running short pre-session capture will be useful to see if you can get same length tracks with given resolution/fps/codec and if no either drop down recording fps or try to speed up encoder settings. I tried other positioning methods (apart from software timings), check/uncheck add/drop frames checkboxes, setting different number of audio samples ... There seems to be no algo/code to intellectually duplicate frames that are too late in their encoding. I also tried setting buffered frames in device to absurdly high value like 50, and this was also not working for screencapture driver and recordings like 20-25 seconds long. It makes sense that no amount of buffering will save you if you are chronically late ... Sounds like trivial bits of info, but because I use cingg as my main screencapture application I thought I better to pen them down before I forgot!

New patch OpenCV
by Andrea paz 19 Dec '23

19 Dec '23

I tried compiling with just the OpenCV patch. I used opencv from the CinGG repository. It compiles successfully, but fails to compile opencv so the plugins do not appear in CinGG. I attach the cin.log

Reminder -- please do not attach large files
by Phyllis Smith 17 Dec '23

17 Dec '23

Even though it is more convenient to attach png and other large files to email, please upload them somewhere else and provide a link instead. The mailing list has limited space and it creates extra administrative work. OK files to attach are, of course, patch and diff files which are nice and small. Even most tar.xz files would be better sent directly to the person who needs it but mentioned in the Mailing List as available for download or sent to an individual upon request. Thanks, Phyllis

libaom downgrade from 3.8.0 to 3.6.1
by Andrew Randrianasulu 17 Dec '23

17 Dec '23

https://cloud.mail.ru/public/KAkQ/AwCYiaiuF in case you like to run resulting cingg distribution on Ubuntu 16 / cmake 3.5.1 (only x86_64 qemu vm tested) I dunno, because I seems to be only one termux user than may be patch 0001 can go in as it shouldn't affect normal or even termux dynamic compilation? Other patches go in order. I hope you get x265 update from earlier folder, so not repeated here. Put new (old) libaom tar.xz in thirdparty/src, make sure you do not have libaom-v3.8.0.tar.xz there, try to build and render small av1 file.
