Hi,

Last stable 4.0.0~201708021339~ubuntu16.04.1 fails to start on Ubuntu 16.04.3 LTS.

Thanks

Not know what's the problem, but I got a workaround by upgrade PyOpenGL via following command:

pip3 install --upgrade PyOpenGL

[PoulKalff]

I got it working same way as PandaJim. Shouldn't it be possible to have the program check pythonopengl-version, to better handle this error?

I think I have a similar problem:
I can not start vidcutter 4.0.0 (for Ubuntu 15.04) on Linux Mint LMDE2 32bit

PPA repos do not work in LMDE2, so I've downloaded the .deb package manually from here:
http://ppa.launchpad.net/ozmartian/apps/ubuntu/pool/main/v/vidcutter/
=> vidcutter_4.0.0201708100203ubuntu15.04.1_i386.deb

I couldn't install the Ubuntu 16.x or 17.x packages, because my python3 version is lower then v3.5.
These Python versions are installed:

$ python3 --version
Python 3.4.2
$ python --version
Python 2.7.9

When I install the vidcutter .deb, these packages are installed automatically:
python3-opengl (3.0.2-1)
freeglut3:i386 (2.8.1-2)
libmpv1:i386 (0.6.2-2)
libavdevice55:i386 (6:11.9-1~deb8u1)
libbs2b0 (3.1.0+dfsg-2.1)
libguess1:i386 (1.2-dmo2+deb8u1)
mediainfo (0.7.70-1)
libmediainfo0:i386 (0.7.70-1)
libmowgli-2-0:i386 (2.0.0-dmo1+deb8u1)
python3-pyqt5.qtopengl (5.3.2+dfsg-3)
python3-pyqt5 (5.3.2+dfsg-3)
libqt5help5:i386 (5.3.2-3)
libqt5clucene5:i386 (5.3.2-3)
libqt5designer5:i386 (5.3.2-3)
libqt5test5:i386 (5.3.2+dfsg-4+deb8u2)
libqt5xml5:i386 (5.3.2+dfsg-4+deb8u2)
libsdl2-2.0-0:i386 (2.0.2+dfsg1-6)
libtinyxml2-2:i386 (2.2.0-1)
libva-glx1:i386 (1.4.1-1)
libzen0:i386 (0.4.29-1)
python3-sip (4.16.4+dfsg-1)

Here is the output when I try to start vidcutter on terminal:

$ vidcutter

ImportError: /usr/lib/python3/dist-packages/vidcutter/libs/mpv.cpython-34m-i386-linux-gnu.so: undefined symbol: mpv_opengl_cb_uninit_gl

Do I only miss a package?!? I have already tried to install the packages python-pyqt5.qtopengl (5.3.2+dfsg-3) and python-pyqt5 (5.3.2+dfsg-3) and mpv (0.8.3-dmo1) in addition, but with no luck...
I have already tried the workaround from PandaJim (install python3-pip, run sudo pip3 install --upgrade PyOpenGL), but with the same results (same error message).

Or is my version of python or libmpv (or any other package) just not compatible to vidcutter 4.0?

If not compatible, where can I get older vidcutter 3.x versions (.deb) for download?
I know that I can download the vidcutter 3.5 "src" package here on github, but I need the precompiled .deb package... ;-) Thank You!

go Fedora.

@dodona2
What's so funny about this?!?
If you don't have a helpful answer... please just don't!

@manjarooo

from your logs i can see that you're on 32-bit and not 64-bit.. there was a bug in VidCutter preventing the latest version from working on 32-bit machines on Linux only. sorry about that. theh good news is v4.5 is being released in about a week from today which has been fixed and tested thoroughly on 32bit machines so keep an eye out for it...

cheers,
Pete

Reproduced on KDE neon User Edition 5.11(Based on Ubuntu 16.04), and probably same as issue #73, #86 and #88
