random console ffmpeg prog
by Andrew Randrianasulu 24 Oct '22

24 Oct '22

I was looking for this mess of hw encoders on ARM singleborad computers and randomly hit this blog: https://www.willusher.io/general/2020/11/15/hw-accel-encoding-rpi4 so apparently default 'OS' on Pi4 uses v4ĺ2 encoder, should be easy to create profile for (just copy vaapi one and edit ) and as bonus you can find python + ffmpeg encoding manager .... another random project is wayland capture program, might not work on intel due to fb modifiers (?) https://trac.ffmpeg.org/ticket/8542 https://github.com/cyanreg/txproto and all this because adventurious user 'goat' reported he had better luck with cin-gg on arm single-board computer under Wayland/Xwayland - namely timeline scrolling performance.

IceWM 3.1
by Andrew Randrianasulu 24 Oct '22

from phoronix https://www.phoronix.com/news/IceWM-3.1-Released ++++ IceWM 3.1 introduces a new window option "frame" to automatically group application windows with the same "frame" value as tabs within a single frame. ++++ this behavior *may* workaround 'too many windows' complain from cin users.

https://github.com/google/security-research/security/advisories/GHSA-vhxg-9… so I downloaded https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/6f53f0d09ea4c9c7f7354f018a8… and turned it into ffmpeg-5.1.patch6 (attached) from description it sounds quite bad, so if this patch does not regress normal files we better to apply it or may be update whole ffmpeg to 5.1.2 ?

Test alpha channel and reroute plugin (from Igor Vladimirsky's blog)
by Andrea paz 10 Oct '22

10 Oct '22

I open a new post to better recall the subject; the discussion in the post "CinGG's Youtube channel" is off topic. I tried to repeat Igor Valdimirsky's tutorial; maybe I did something wrong but my result is not good. Already with the default overlay (Normal) the result is not exactly the same as in the tutorial. For example, the outline of the letters is all white while in the tutorial there are plays of light and shadows that make it three-dimensional. But the worst comes when I set the center track to "Multiply": a completely wrong color comes out! See video: https://streamable.com/a7viox One difference is that I used a video source (h264, mov) and not a still image as in the tutorial, but I don't think it makes any difference.

MIDI control surface in CinGG
by Stefan de Konink 04 Oct '22

04 Oct '22

Andrea started the following thread on the forum. <https://www.cinelerra-gg.org/forum/forum-hardware/using-midi-control-surfac…> I obtained quite a cheap DJ Controller. My ambition was to use it with Cinelerra for editing. I was quite surprised it was actually MIDI based. I have tested midi2input, it has a steep learning curve. But given they have examples how to do it for kdenlive and olive, it is an engineering approach in making a device available. >From what I have seen from "Mixxx" which fully integrates with multiple midi devices, having an integrated mapping would make sense. But that would also suggest to have they keyboard mapping as a first class citizen as well. -- Stefan

proot on termux

I have i386 debian 11 on my arm tablet now, but road to it was somewhat bumpy. debootstrap as provided by termux does not like --foreign option, so I tried modification of scrip commands found at https://github.com/sp4rkie/debian-on-termux/blob/master/debian_on_termux_10… (I have Android 10 tablet) $ debootstrap --variant=minbase --exclude=systemd --arch=i386 bullseye deb_11 but you need to set main repo here or create debootstrap/mirror by hand REPO=http://ftp.debian.org/debian/ unset LD_PRELOAD $ proot -0 -b /dev -b /sys -b /proc -b /system -b /apex --link2symlink -r deb_11/ -q qemu-i386 /bin/bash --login (for some reason my system need /system and /apex added to proot bind directories for qemu to function) this worked but ssl / ca-certificates were not installed, and coreutils for some reason needed re-install by dpkg -i /var/cache/apt/archive/pkg.deb also debootstrap/debootstap script had termux pathes in it, so I edited them back for normal Linux/debian pathes after installing /etc/resolv.conf network/apt worked but building man page index was a bit slow.

September AppImages available a little early
by Phyllis Smith 29 Sep '22

29 Sep '22

End of month AppImages are now available. (I had to make them early because I will not be able to on the usual last day of the 30th). It takes about 4 hours on average to create the 6 versions with the Alt-h manual help when nothing goes wrong. ***************** this release notes ****************** *GIT for Cinelerra-GG has the following changes from 09/01/2022-09/30/2022* *Flac has been upgraded to 1.4.0 *from 1.3.2 (it was May 2013 when 1.3.0 was first released). In addition Andrew has added a Flac compression level option to the gui so that the user can select their preferred level with the default being 0. Thorough building and testing was done by Andrea. *Tiff has been upgraded to 4.4.0 *from 4.3.0. In addition, a patch was made by Andrew to fix the problem discovered by Miroslav where “lerc” being compiled was giving errors. *VP9 webm* render format has been improved/simplified/made default as a result of *Miroslav’s work*. *ALAC audio* render formats added by Andrew. ALAC is Apple’s version of lossless codec. A fix for armv7l build was added to the guicast/Makefile *by Andrew*. Minor *manual changes added by Andrea *as errors are discovered and slight improvements needed.

Re: [Cin] Issues related to Motion Plugin

Georgy, I suppose it was not intentional, but in case this did not arrive to Cin ML (likely, it's not in the archive), I want to send this email, because I worked a couple of hours on it, and I mentioned it in another email today. I need it to show what issues I had. -- Miroslav Rovis Zagreb, Croatia https://www.CroatiaFidelis.hr my PGP-key: https://www.croatiafidelis.hr/FCF13245ED247DCE443855B7EA9884884FBAF0AE.asc I'm removing one layer of citation, for legibility, as if Georgy sent it, not me. ========================================================== On 220926-10:20+0700, Georgy Salnikov wrote: On Sun, 25 Sep 2022, Miroslav Rovis wrote: > > Phyllis has such a very shaky example.

Unpack it, there are two files: the source video clip, and the cingg project file. This is a rather difficult example not only because of strong shaking. Moreover, the video is taken perhaps from a moving car, so the landscape itself in the viewport is changing. The example project demonstrates the possibility of the Motion plugin to switch from one key part of image to another as the former part goes off the viewport, becomes obscured or changes shape. This is not smoothing video, but freezing it. The result is not completely still, but additionally applying vidstab to it perhaps should improve the result once more. To test, do the following after unpacking: Open shaker2.xml (replace current project) Make sure: Motion and Time Average must be off Rewind to the beginning Uncheck 'Play track' Open Motion controls dialog Action: Do Nothing Calculation: Save coords to tracking file Scroll timeline forward, set cursor after the next keyframe Action: Do Nothing Calculation: Save coords to tracking file Repeat that for all the rest keyframes (total of 4) Close Motion controls dialog Rewind to the beginning Switch Motion on Check 'Play track' Play forward up to the end Video will be still very shaky. The file 'motion-shaker4' will appear in /tmp Uncheck 'Play track' Rewind to the beginning Open Motion controls dialog Action: Stabilize Subpixel Calculation: Load coords from tracking file Scroll timeline forward, set cursor after the next keyframe Action: Stabilize Subpixel Calculation: Load coords from tracking file Repeat that for all the rest keyframes (total of 4) Close Motion controls dialog Rewind to the beginning Switch Motion on Switch Time Average on Check 'Play track' Render project Now compare the result of rendering with the original one. .......
