nuxorg · 2011-03-09 16:35:18

Just installed OpenShot (x86, community/openshot 1.3.0-2), but it fails to launch.

Inxsible · 2011-03-09 16:37:58

probably because it requires python2 and not python (which is now at version 3 in Arch)

you might have to change the scripts for openshot to point to python2 instead. Try it and see if it works.

nuxorg · 2011-03-10 07:59:33

There is already python2, not python.

I have the same problem. Does anybody know a solution?

Arch x86_64

ronnylov · 2011-03-13 20:49:28

I do also have this problem.
Maybe we should report it as a bug?

EDIT: http://openshotusers.com/forum/viewtopic.php?f=12&t=814

Maybe the latest update of mlt is causing problems?

Openshot did work for me when I installed it a few weeks ago but now it does not work anymore.

Hi

For me it is working but when rendering the projects, exporting the projects no matter to what I have no sound.
During the edit, I have sound...

BTW, it is the same with kdenlive....

Rebuild it using abs, if it works, report it on the arch bug tracker.

ronnylov · 2011-03-16 19:26:13

This is what I get when trying to install the ABS build of openshot:

and then I try to start openshot:

Did I understand correctly that I shoult NOT report a bug if ABS build did not work?
When should a bug be reported?

EDIT: Now it works!

First I found this page: http://www.linuxjournal.com/content/int … g-openshot
They got the same error. I checked my PYHONPATH and it was empty.
I added some paths:

[ronny@r1arch ~]$ echo $PYTHONPATH
:/usr/lib/python2.7/site-packages/:/usr/bin/openshot/
[ronny@r1arch ~]$

It still did not start. I thought of the "three files from ~/src/mlt/src/swig/python" and how to get the source?
Well I installed mlt and mlt-python-bindings from ABS (got both from ABS mlt package).
Now I thinked maybe it got installed correclty now so I tried to start openshot (without manually copy the swig files).
Voila! It works!

I am not sure why installing mlt from ABS gives better results, or maybe it was the PYTHONPATH that fixed it?
So if there is a bug to report, where is the bug then?

fettouhi · 2011-03-22 10:03:22

Still can get it to work even if I set the pythonpath.

ronnylov · 2011-03-22 14:12:30

I did also reinstall openshot, mlt and mlt-python-bindings from source with ABS instead of install them as binary packages.
Another thing I did was creating additional symlinks
/usr/lib/libmlt++.so.2 -> libmlt++.so.0.6.2
/usr/lib/libmlt.so.2 -> libmlt.so.0.6.2

I am not sure which one of the changes that made it work for me (that is a problem when making many changes).

kasbah · 2011-03-22 18:16:03

Same issue here. I cannot rebuild mlt from abs:

Traceback (most recent call last):
  File "/usr/lib/python2.7/encodings/__init__.py", line 157, in <module>
    codecs.register(search_function)
AttributeError: 'module' object has no attribute 'register'
python development missing
    Aborting...

I rebuilt openshot from ABS with no effect. I cannot find mlt-python-bindings in ABS. I tried openshot-bzr from AUR with which I get:

$ openshot

------------------------- ERROR 1 ------------------------------

Error Message: No module named xdg.IconTheme
----------------------------------------------------------------

OpenShot has failed to import some of the Python files or libraries 
required for our application to run.  Here are some trouble shooting
tips:

Tip 1) Check if MLT can be successfully imported in Python.  Run the 
 following commands, and see if any errors are displayed.  If you get 
 an error, you need to investigate the correct way to install MLT.
 NOTE:  Do not type the $ or >> characters in the examples below.

       $ python
       >> import mlt
       >> mlt.Factory().init()

Tip 2) If MLT is working from the first example, then the next tip is 
 to look at the above error messages very closely, and google for more 
 help.  It's likely the problem is already reported, and maybe there is
 a simple work-around.  Also, you can search for bugs or report a new 
 bug at https://bugs.launchpad.net/openshot.  Good luck!

creating symlinks doesn't help either

Rebuild mlt and mlt-python-bindings works for me!

ronnylov · 2011-03-23 13:35:36

mlt-python-bindings comes together with mlt on ABS (there are two pkgbuilds in the mlt directory).

schivmeister · 2011-03-26 07:59:01

Please file a bug report, since the binary does not work and a rebuilt package does.

ronnylov · 2011-03-27 09:11:21

I have filed this bug: https://bugs.archlinux.org/task/23462

This is the first bug report I have ever made so if I made any mistake it is because I am new to this...

And the bug is now fixed. I think this thread can be marked as solved.

1) Fully update your system
2) Remove any symlinks you might've made (for openshot libs or python binary)
3) Remove ~/.openshot (backup if you must)
4) Remove openshot, mlt, mlt-python-bindings (pacman -Rscn openshot; -Rd if you don't like what else is being removed)
5) Reinstall the packages

Strange why for some of us it works. Clearly, we'll have to look somewhere else for the cause.

Really strange

I did also get the error again after the upgrade of mlt and mlt-python-bindings to latest version 0.7.0-2.
And I did the same thing as before to fix it.
Rebuilt mlt with ABS which created packages for both mlt and mlt-python-bindings.
I installed them both and then openshot works again.
So the same error and the same solution again for me.

Confirmed , rebuilt MLT with ABS works.

I am very new to Arch - my first (successful) install was ~1 week ago. I, too, was unable to open OpenShot and got the same errors. There was an update, though, to mlt (to 0.7.0-1 as I recall) and it worked. Sadly, there was another update either today or yesterday (to mlt 0.7.0-2) and I am now back to "square one".

EDIT: I have just downgraded to mlt-0.6.2-3 and mlt-python-bindings-0.6.2-3 and OpenShot opens and works well. It seems my troubles began upon the upgrade to 0.7.0-1 and not 0.7.0-2.
