Description:
motion traking fails very often with all algorithm but kcf. It works in upstream appimage

I tried to install opencv from testing (4.5.5-7) and mlt-git from Aur without any results.

Reason for closing:  Works for me

Please give step by step instructions and provide sample files to reproduce this.

sample files

https://www.dropbox.com/sh/799sn40ufdhwqvp/AAA-_q1x7MQ2Y3O3OfccqU6ra?dl=1

steps to reproduce

open kdenlive
open prova.kdenlive
select the clip in the timeline
go to effect stack
in motion tracking click on "analyze"
try with different algotithms

p.s. sometimes also kcf fails.

mmmh

Just to try I installed opencv from here: https://mirror.cachyos.org/repo/x86_64_v3/cachyos-v3/

and this solved the problem.

opencv 4.6 seems to work better with csrt but not with others alghoritms

opencv 4.6 from here https://mirror.cachyos.org/repo/x86_64_v3/cachyos-v3/

works perfectly.

Maybe the -O3 optimization?
Comment by Guido Iodice (guiodic) - Tuesday, 07 June 2022, 14:18 GMT
according the cachyos devs, the pkgbuild is identical but makeflags are:

#CPPFLAGS=""
CFLAGS="-march=x86-64-v3 -O3 -pipe -fno-plt -fexceptions \
-Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security \
-fstack-clash-protection -fcf-protection"
CXXFLAGS="$CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS"
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"

well we can't compile Arch packages with v3 optimizations, so I don't think there's much we can do here.
Comment by Guido Iodice (guiodic) - Tuesday, 07 June 2022, 14:56 GMT
I understand. What about only O3? maybe it works.
Comment by Guido Iodice (guiodic) - Tuesday, 07 June 2022, 16:04 GMT
btw I strongly doubt that the appimage is compiled with optimization. Motion tracking work fine there.

> I understand. What about only O3? maybe it works.

Well, can you please check?
Comment by Guido Iodice (guiodic) - Saturday, 11 June 2022, 12:05 GMT
my computer is not that fast to build opencv within an acceptable timeframe, I tried to build it on Opensuse obs but fails because at some poit it download a library and it's not permitted...
can you please build a -O3 somewhere so I can test it?
Comment by Antonio Rojas (arojas) - Sunday, 12 June 2022, 09:34 GMT
Actually, opencv already builds with -O3 by default

Comment by Antonio Rojas (arojas) - Tuesday, 21 June 2022, 18:13 GMT
so, anything else to try here or should I just close it? This seems to be a performance issue, I can't reproduce this on my system
