Hello,

did you install libmpv properly ?

Please try

sudo apt install libmpv-dev

Check with

locate libmpv.so

Regards

legluondunet · 2018-03-11T08:13:56Z

I installed libmpv-dev and now vidcutter compiled without error.
But now how I can launch it?
I tried this:

$ python3 setup.py build
$ cd build/lib.linux-x86_64-3.6/vidcutter
$ python3 videocutter.py
Traceback (most recent call last):
File "videocutter.py", line 42, in
from vidcutter.about import About
ModuleNotFoundError: No module named 'vidcutter.about'

Rockus2018 · 2018-03-11T10:16:50Z

Do the spell

python3 setup.py install

However, vidcutter depends on several packages:

apt install libmpv*
apt install mediainfo
apt install libav-tools

(It's a much better choice to install 'ffmpeg' directly instead of 'libav-tools')

To finally run vidcutter some more online magic is needed:

apt install python3-pip
pip3 install -U pip
pip3 install -U pyqt5
pip3 install -U pyopengl

Maybe an

apt install fonts-noto*

is useful too ...

And now you can simply type

vidcutter

on the command line ...

(three error lines are common :0)

legluondunet · 2018-03-11T12:26:34Z

1°)

$ sudo apt-get install libmpv*
$ sudo apt-get install mediainfo
$ sudo apt-get install libav-tools

I just verified, all this packages are already installed on my Ubuntu

2°)

Do the spell
$ python3 setup.py install

I don't want to install it, I just want to launch it directly after compilation, like I aIways did when I compile program myself, is it possible with vidcutter?

legluondunet · 2018-03-11T12:40:00Z

On Linux Debian/Ubuntu, you don't need to do this:

To finally run vidcutter some more online magic is needed:

apt install python3-pip
pip3 install -U pip
pip3 install -U pyqt5
pip3 install -U pyopengl

Instead install this package from official Debian/Ubuntu depot:
$ sudo apt-get install python3-pyqt5.qtopengl

I just installed it and now my setup test give me no more error:

$ python3 setup.py test

OK

But I still can not launch directly vidcutter from his compilation folder.

Rockus2018 · 2018-03-12T11:29:07Z

Well, you prefer a lean system.

Good luck with the outdated library, vidcutter seems to be sensitive at this point ...

I'm running Mint 18.3 i.e. Ubuntu Xenial Xerus and got PyQt5 v5.5.1 from standard repository, which version is literally too old to run smoothly. You got v5.7, but PyPi installed v5.10.1 through pip ...

Did my very best, but every time I run vidcutter I'm getting two error lines on stderr

Exception ignored in: 'mpv._c_getprocaddress'
TypeError: an integer is required

or via vidcutter --debug

2018-02-10 21:11 - root - CRITICAL - <class 'mpv.MPVError'>: not supported
2018-02-10 21:29 - root - CRITICAL - <class 'TypeError'>: an integer is required

Could it be, that @ozmartian grounded the error handler by intention ?

BTW, @ozmartian listed the dependencies for Ubuntu in the module helpers.py "for a noticeably better integrated experience":

python3-dev libmpv1 libmpv-dev python3-pyqt5
python3-pyqt5.qtopengl python3-pyqt5.qtx11extras
ffmpeg mediainfo python3-opengl

Look at vidcutter/libs/mpvwidget.py line 30 pp. - you will need the wrapper python3-opengl too.

The installed launch code script is

#!/usr/local/bin/python3
# EASY-INSTALL-ENTRY-SCRIPT: 'vidcutter==5.5.0','gui_scripts','vidcutter'
__requires__ = 'vidcutter==5.5.0'
import re
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(
        load_entry_point('vidcutter==5.5.0', 'gui_scripts', 'vidcutter')()
    )

Rockus2018 · 2018-03-12T13:17:16Z

Hopefully did a

git clone -q --depth=1 --branch=master https://github.com/ozmartian/vidcutter.git vidcutter

for the newest fixes ... nope, had to edit mpvwidget.py manually again ...

cd vidcutter
sudo python3 setup.py install

Now I could run vidcutter from command line or with a crippled code too

rockus@Lychee ~ $ python3
Python 3.6.4 (default, Feb 19 2018, 04:35:39) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pkg_resources import load_entry_point
>>> load_entry_point('vidcutter==5.5.0', 'gui_scripts', 'vidcutter')()
QApplication: invalid style override passed, ignoring it.
Exception ignored in: 'mpv._c_getprocaddress'
TypeError: an integer is required

Surprise, a

vidcutter --debug

delivered

... - root - CRITICAL -
... - root - CRITICAL - <class 'mpv.MPVError'>: not supported
... - root - CRITICAL - <class 'TypeError'>: an integer is required

earlier, and now

... - root - CRITICAL -
... - root - CRITICAL - <class 'TypeError'>: an integer is required

Rockus2018 · 2018-05-18T23:06:51Z

Giving v5.5.5 a try - I had to say good-bye to libmpv v0.14 because no vidcutter GUI came up ...

However, after compiling against libmpv v0.22 the above error messages are gone.

OS is Linux Mint 18.3 Cinnamon 64 bit - therefore I had to edit mpvwidget.py for the use of pyopengl before.

ozmartian · 2018-05-29T16:53:32Z

the fonts used by the app are included within the Qt based resource file (i.e. vidcutter/resources.py) which get loaded on app start... the only case where physical, on disk font files are required is the mpv library when rendering text as part of the on-screen-display text messages... having fonts in resource files makes things a hell of a lot easier ensuring things all run as planned across all platforms and packaging formats and in the case of the OSD text the code will first test to see if Noto Sans is already available in your desktop and revert to using DejaVu Sans if not (dejavu sans has become a standard font preinstalled on most distros now)...

wouldn't you be better off using the flatpak or snap or even AppImage... the flatpak from flathuib is being actively maintained, latesty ffmpeg and mpv libraries along with latest codecs and app codebase so no headaches, its just works :)

Rockus2018 · 2018-05-29T23:46:05Z

Wow, he is real :)

I'm so sorry, nothing above will 'just work' under Linux Mint, because I remember
the line 34 in vidcutter-5.5.0/vidcutter/libs/mpvwidget.py has to be changed from

if distro.id().lower() in {'ubuntu', 'fedora'}:

to

if distro.id().lower() in {'ubuntu', 'fedora', 'linuxmint'}:

before ... and please add 'debian' too, if I guess right.

Well, in branch 6.0.0 you finally gave up. But 6.0.0 is not master branch yet ...

BTW, please look at #168 - I'm not the only one able to get rid of his system fonts : )

I don't like the [flatpak snap docker] solutions - wanna keep minimum control of my machine.

Nevertheless, many thanks for learning so much about all kinds of installing software with your tool.

This issue was firstly about the compilation on Ubuntu.
I just compiled the last Vidcutter git source with success on Ubuntu 18.04.
So I can close this issue.
Thank you for your help.
