Same problem ever after upgrading

Openshot is not open ?
Try that : https://answers.launchpad.net/openshot/+faq/989

Please read the following thread:
https://answers.launchpad.net/openshot/+question/95857

You might have to scroll to the bottom of it to find the answer. The python bindings for MLT are not working correctly, which is the error you are seeing. Good luck!

Hi cenwen. I have been trying your suggestion before writing here but it did not work. Thank you.

Hi Jonathan. As you can see, you have been linking a bug report opened just by myself :) That confirms it's not the first time the problem occurs, is solved and occurs again :(

In the following you can find the results of 4 suggestions from that thread. None of those I have been trying makes the job. Jonathan, could you please be more precise about the specific suggestion I should follow from that thread?

Thank you all for your time!!!
Have a nice day.

Hi cenwen.

Thanks for your suggestion.
Unfortunately I cannot see the difference between that link and the suggestions reported in your previous link.
If I don't go wrong, both links suggest to uninstall OpenShot, remove that openshot directory and reinstall it from ppa.

I have been trying again anyway, but with no luck.

thanks!

Any other suggestion, please?

yes i have yet reading the beginning of your message and i have seen somewhere python-mlt missing.
Please, check your dependencies : http://openshotusers.com/forum/viewtopic.php?f=12&t=33

Unfortunately I cannot see the difference between that link and the suggestions reported in your previous link.
If I don't go wrong, both links suggest to uninstall OpenShot, remove that openshot directory and reinstall it from ppa.

Yes it's a total removing as a last resort. That's work.

Another track :
$python
>>>>import mlt (i know that you have already that but it will be more clear and if you have install a new dependencie (think to look at the Edit lines)and i want to be sure)

Another thought
$gdb python
(gdb) run openshot.py

We are testing a new version modifed with the new bugs reports. So perhaps in another last resort.

cenwen, I have been following your 1 suggestion and discovered that x264 package was missing. After installing it the situation does not get better:

Hi manolo

Perfect i was also thinking at melt and python-mlt when i was saying that.

Thanks for this great feedbacks

Initialy i have planned to you creat a symbolic link but i will wish to know the result of this commands before :
echo $PYTHONPATH
ls /usr/lib/*libmlt*

If you have something returning (post here the result please, thanks) you could try this :
sudo ln -s $(ls -C /usr/lib/libmlt.so.0.5.0 | cut -f 1 -d' ') /usr/lib/libmlt++.so.2

& echo $PYTHONPATH
(returns nothing)

$ ls /usr/lib/*libmlt*
/usr/lib/libmlt.so.0.5.0
/usr/lib/libmlt.so.2
/usr/lib/libmlt++.so.0.5.0
/usr/lib/libmlt++.so.3

Should I execute that command anyway?

Thanks.

No we are trying something
in a console do that :
export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.6/site-packages/
and after try openshot

~$ export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.6/site-packages/
(no results, it means everithing is ok :)

Use the following command to install OpenShot:

So it does not seem to work.
Also, could you please remove that frustrating suggestion:
Use the following command to install OpenShot:
  $ sudo python setup.py install

??? :)

It wast just a thought
Post me this command and after we will create exactly the link
ls -l /usr/lib/*libmlt*

~$ ls -l /usr/lib/*libmlt*
-rw-r--r-- 1 root root 120324 2010-02-16 10:17 /usr/lib/libmlt.so.0.5.0

lrwxrwxrwx 1 root root 17 2010-02-17 08:54 /usr/lib/libmlt++.so.3 -> libmlt++.so.0.5.0

so we are going to try that :
sudo ln -s $(ls -C /usr/lib/libmlt.so.0.5.0 | cut -f 1 -d' ') /usr/lib/libmlt++.so.2

cenwen, thanks for your time.
Unfortunately that hasn't solved the problem.

Hi Manolo

Sorry i have done an error with the link. So it's why i do not understand the sens of your remarq.
Try that :
$ sudo ln -s /usr/lib/libmlt.so.0.5.0 /usr/lib/libmlt++so.2

And the good link is here : http://openshotusers.com/forum/viewtopic.php?f=12&t=253

Hi cenwen.

So many thanks for your suggestions. I have been trying crating that symbolic link but OpenShot still does not open. Please see at the bottom of this post.
Moreover, I beg you to be more precise about the specific suggested steps you want me to follow from that link. In fact, about that I am quite confused. Between the different suggestions, for example, again I find the already tried "uninstall and reinstall" steps. I suppose you don't want me to try it again, do you?

In order to me more clear, I beg you to please paste here all the steps you want me to follow.
Thank you very much for you help and for your time!

Have a nice day!!! :)

Hi Manolo

I'm late like always, so the explanation now :

1) Remove the "openshot" 1.0 package using Synaptic
2) Remove the following folder (if it still exists): /usr/share/openshot
NOTE: If you have trouble deleting this folder, try this command:
$ sudo rm -r /usr/share/openshot
3) Install "openshot" version 1.1 (using the DEB or PPA)

Like you can on the forum, somebody have informed us that for resolving his problem (like you), the last command for creating a symbolic link have walked for some people and not for others.
We searching, we searching.
Thanks to be patient.

You can try that too (more fast and simple) :
sudo apt-get remove --purge libmlt++2 openshot python-mlt
sudo apt-get install libmlt++2 openshot python-mlt

I have followed just your last post. Executing:
sudo apt-get remove --purge libmlt++2 openshot python-mlt
It also removed KDEnlive.

After executing:
sudo apt-get install libmlt++2 openshot python-mlt

the result is:

Could you do so the first track (=post) and when you have remove openshot, delete the file .openshot too by this command :
rm .openshot
Do that after the number 2)
Thanks

I have followed your advice after executing the "purge" operations. Unfortulately the result is negative:

Incredible, we can resolve that same in all removing. All that we have try is without effects. For the moment, i don't know (and i have not a lot of time too). I will think at your problem and will look all that we have done. Perhaps today if i have the time (but it is not sure). Thanks
Olivier

Thanks for your help. I'll be waiting.

Have a nice day.

It is just to say you that i have not forgotten you. I have just less waste-time and i'm searching.

Hi cenwen. Thanks for your interest.
I suppose it could be a general problem with openshot. i have been trying to run it with another Ubuntu 9.10 machine and the problem persists.

I'll try purging OpenShot on that machine and reistalling it from PPA as soon as I can.

Have a nice day.

Hi
I'm on today.
A question (because you are not alone in this cas) : have you a folder openshot in /usr/share ie /usr/share/openshot
And could you pass this command too :
whereis openshot
Thanks for your patient

whereis openshot
openshot: /usr/bin/openshot /usr/share/man/man1/openshot.1.gz

Thanks for your time

Ha Ha the same symptom. i'm openning a thread on the french section on this problem and after i will open another thread in english on the forum too.
We have perhaps find the result of the update and i hope find a solution for everybody.
The thread is here if you are interresting by learning french (je plaisante !!!!!!!!! = i'm laughthing) : http://openshotusers.com/forum/viewtopic.php?f=18&t=298&p=1133#p1133

after, we will see all at the beginning.

Hi,
i want to know if you have a folder openshot in /usr/share. In this folder you have some anothers folder like classes", "locale", "transitions", "effects", "export_presets" ,....
And have you in a folder openshot in /usr/share/python-support ?
It is very important

Hi cenwen.

Thanks for your help. Unfortunately, as I said before in the output of the "whereis" command, I have got no openshot directory in /usr/share.

In fact:
/usr/share$ ls -la | grep open
drwxr-xr-x 3 root root 4096 2010-02-24 11:42 openoffice

Hum. There is no folder call openshot here (ie /usr/share/python-support) ?
Could you find in your systeme (in the folder /usr/ in your system ) if you have a folder call openshot.
I think (and more and more i explore this track, i'm going in that direction) when the update has been done , something is happen and it has loose the place than where he must be but for two people the place where he has land his different.
Try to seach in /usr/share/pyshared/ if you have a folder openshot.
Thanks.
Olivier.

Jonathan will come to our help with a script and the instruction here : https://answers.launchpad.net/openshot/+faq/1032

Cenwen, thanks again for your time.

I am reading your answer and I think there is an error. I repeat that I HAVE GOT the "python-support" folder and that I HAVE NOT GOT the "openshot" folder.

Can you please confirm that there is an error in your last but one answer?
Thank you!

Missing Shared Libraries!!!
-----------------------------------------------------------
A shared library can not be found in the previous test, which is breaking python-mlt.
Check the /usr/lib/ for the missing library file. If needed, create a link to the
correct file. For example: ln -s /path/to/original /path/to/link

Debug File 'openshot.debug'

This script has created a file called 'openshot.debug' which
contains all of this output. If you are having trouble installing
OpenShot, you can attach this file to your bug report.

manolo,
So, it looks like you have installed a newer version of libmlt1, which is causing the problem. _mlt.so is trying to link to a file called /usr/lib/libmlt++.so.2, but that file does not exist.

You could try creating a link called "/usr/lib/libmlt++.so.2" that points to "/usr/lib/libmlt.so.0.5.0" and see what happens.

I think this is the syntax:
sudo ln '/usr/lib/libmlt.so.0.5.0' '/usr/lib/libmlt++.so.2'

Jonathan you have forgotten the symbolic so the syntax is :
sudo ln -s /usr/lib/libmlt.so.0.5.0 /usr/lib/libmlt++.so.2
The quote ' are she obligatories ?

This is the output of that script after creating a HARD link, as Jonathan said.

I believe the problem is very simple. The python-mlt package was built using an older version of libmlt1. Either you will need to replace libmlt1 with the package that is in the Ubuntu karmic repository, or build the python-mlt bindings for your newer version of libmlt1.

I will make a FAQ for building the python-mlt bindings later today, if you are interested in that approach.

Thanks!

Hi Jonathan.

I am interested in the solution. I don't know how to restore the karmic repos version.
Tell me what to do, whatever to solve the problem.

Thanks.

Just upgraded Openshot. I am still unable to run it.

sudo ln -s $(ls -C /usr/lib/libmlt++.so.* | cut -f 1 -d' ') /usr/lib/libmlt++.so.2

Hi,
i think that Jonathan has forgotten to create the faq how to build python-mlt.
Perhaps (it is just a thought) you should wait Lucid (in two weeks). After, we will see if it is always an issue. For Lucid, python-mlt is changed by python-mlt2 so it will be resolve certainly this issue.
