EDIT: I think that last time I posted in a Gunnar Thalin thread, he popped up a day or two later.

I'm still alive!
I don't seem to get notification emails?

But will there ever be a possibility of using it on Linux? Since the source code isn't available and the author hasn't been heard from in 8 years, I suppose not a chance?

Funny, the reason I'm here is to post the next post... see below.

[guth]

I don't know if there's any interest still, but I (finally) think it might be a good idea to make the Deshaker source code public.

Any recommendation on the best way to do this?
Do I just put a zip on my Deshaker page? Or should I put it on GitHub, or something, and how much work is that? Maybe someone else would like to "run" it??
And what license? I don't really care if people make money on it (anymore), but is it still a bad idea to make it completely free? (Excuse my lack of knowledge and interest in legal stuff.)
Also, please keep in mind I've become rather lazy.

[Boulder]

The notification emails have been broken since a long time ago

I vote for putting the source code on GitHub. I do not believe that it's a big job but someone else can confirm that - or just add it to their repo I'm sure there's something useful for someone in the code sooner or later.

[StainlessS]

I dont do GitHub and so cannot comment on how easy that would be.

I don't really care if people make money on it (anymore)

But I'm guessing that you would prefer not to have someone take totally Freeware source, change a few labels
to say that they are the authors, and make a packet of cash from the people that they deceive.
Open source with GPL would maybe be best.

Nice to see you again Guth

On GitHub it would be there ~forever, and it's easy, few clicks if your source is one-few files, do it through the website there, not through Git.

I would say, good luck if anyone by some magic manages to make money out of it.

This is do whatever you want license:

The Unlicense

A license with no conditions whatsoever which dedicates works to the public domain. Unlicensed works, modifications, and larger works may be distributed under different terms and without source code.

This is simplest preserving a credit to your name, and preserving the open source if it's not incorporated into some MicrosoftDub:

MIT License

A short and simple permissive license with conditions only requiring preservation of copyright and license notices. Licensed works, modifications, and larger works may be distributed under different terms and without source code.

I have sold it to a few companies in the past, at least. Without even trying.

Anyway, thanks for the input, guys. If nothing unexpected happens I'll put it on GitHub within a couple of weeks.

[guth]

The Deshaker source code is now on GitHub:

https://github.com/gu-t/Deshaker

Please let me know if you see anything weird. I've used Git before, but I'm new to GitHub.

Most gracious of you, cheers Guth.

Binaries exist on my Deshaker page, that I link to. Or, what do you mean?

Oh thanks

[Rob105]

Can i somehow set a horizon across different control frames so Deshaker would stabilize rotation to match this horizon or any way to set horizon at all?

Here's sample video https://www.upload.ee/files/15288523..._clip.zip.html

What approach would you use to make horizon straight with Deshaker?

[stephen22]

Find a level frame and process from there with rotation smoothness -1, max correction some large number. Reverse the first section and process similarly. Unreverse and join the 2 together.

Hi, I made a PowerShell script [+batch caller] which will pick up all .LOGs from current [or specified] folder and generate fileName_OGG.txt chapter info per LOG (ie: to use with MKVmerge). Minimum duration can be specified (default 75sec). FPS must be known (default NTSC). Has chapter name skeleton as used in mkvtoolnix-gui.exe.
Here's Log2chaps.ps1 script:

  # PARAM must be first command
param ( [int]$gi_minSec=75, [float]$gr_fps=29.970, [string]$gs_chapSkel='Chap <NUM:2>',

Thank you !!

Your plugins have been a great support for me over the years, thanx for the contribution and all the work!
