OpenShot does not start, gives no error message

[in0giro]

ahoy all,

i am trying to install the 1.2.2 OpenShot ebuild on Gentoo found here:

http://bugs.gentoo.org/283673

it builds and installs cleanly. however, when trying to start the application, nothing happens. the first run in a terminal gives this output:

Code: Select all

$ openshot
--------------------------------
   OpenShot (version 1.2.2)
--------------------------------


then subsequent runs give a slightly modified message:

Code: Select all

$ openshot
--------------------------------
   OpenShot (version 1.2.2)
--------------------------------
Process no longer exists: 7216.  Creating new pid lock file.


i have been searching the web and this forum for something, but all the other issues usually have a little more to go on. my problem here is that i have no error message.

i have been unable to find a "debug" option, but did modify the OpenShot debug script to run on Gentoo and attached the results. for here, it looks like everything is installed OK.

it also does not seem to be a Gentoo issue, as many are using this ebuild fine.

can anyone shed some light? or at least give me a way to find some more info (log, debug option, etc). thanks in advance.

peace

Hi,
Just a thought.
Try to remove the folder hidden .openshot by

Code: Select all

rm .openshot

Another thing. It seems that you use the version 0.5.10 of MLT, it should be benefit if you use the 0.6.0 (or the 0.6.2 which is a minor version)
Thanks.

thanks for the tip, but i had found that suggested in many places and tried it to no avail.

unfortunately, there is no 0.6.x ebuild available for Gentoo yet, and i am not an ebuild builder myself. i will try to simply update the latest ebuild 5.10 to use the 0.6.2 version of MLT and see how it goes... OK, just renaming the ebuild to 0.6.2 built the newest MLT of the same version and installed it fine. melt shows version 0.6.2, however trying to run openshot results in the same thing: no error messages (aside from the message about the PID), quits immediately.

thanks again for the help. any chance you could let me know how to get some debug output?

Can you try playing a file with both ffplay & melt?

Use the syntax:

Code: Select all

ffplay filename

Code: Select all

melt filename

ahoy Andy,

thanks so much for the help.

OK, i tried both of your suggestions:

Can you try playing a file with both ffplay & melt?

Use the syntax:

Code: Select all

ffplay filename

Code: Select all

melt filename

with both DV and OGV (Theora & Vorbis) files. both videos played fine in ffplay and melt. the only possible error i see in the terminal output is:

Code: Select all

ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave

however, the audio was fine on both videos, synced and normal (i have Pulse Audio running).

just in case, here is the terminal output for ffplay:

thanks again. if you have some more suggestions, i would really appreciate it, as i have yet been able to start OpenShot once with the past few versions.

In that case maybe there is a missing dependancy. Check here:

http://openshotusers.com/forum/viewtopic.php?f=12&t=372

The package names in that list are for Ubuntu, but hopefully you can work them out for your distribution.

[Cenwen]

I am nearly sure that his problem comes of his version of libsdl certainly libsdl1.2debian-alsa instead of libsdl1.2debian-pulseaudio so it is really a problem of dependencies. Check well all of them.

thanks for the reply. i went through each package listed there and found the corresponding Gentoo ebuild (i.e. package) with my current versions:

media-libs/x264-0.0.20101029
media-video/ffmpeg-0.6
dev-lang/python-2.6.6-r1
dev-lang/python-3.1.2-r4
dev-python/pyxdg-0.19
dev-python/pygtk-2.17.0
dev-python/pygoocanvas-0.14.1
x11-libs/goocanvas-0.14
media-libs/mlt-0.6.2
media-plugins/frei0r-plugins-1.1.22-r1
media-sound/sox-14.3.1
gnome-base/librsvg-2.26.3
media-libs/libsdl-1.2.13-r1

aside from slight version differences (where the Gentoo version is usually more recent), i have all the dependencies listed there. also, the original Gentoo ebuild for OpenShot pulls these in. since that ebuild seems to be working for some people, this is not a surprise:

http://bugs.gentoo.org/283673

thanks for the help again, but it seems like i have all dependencies installed.

i know i keep asking this (and have not found an answer elsewhere in the forums, so maybe the answer is no), but is there a way to get more details or debug info or a run log of what OpenShot is doing when it simply quits almost immediately after starting?

when i saw your post, i thought "BINGO"!!! however, my libSDL is installed with both ALSA and PulseAudio bindings (in Gentoo, there is not a separate package, but just different USE flags or options that change how the package is built; in my case, both the PulseAudio and ALSA SDL drivers are installed because of my USE flag settings). i tried reinstalling SDL it without ALSA bindings, for both the stable (1.2.13-r1) and unstable (1.2.14-r5) versions. no matter what, OpenShot does the same thing: terminates immediately after the messages as i posted at the top of this thread.

thanks again for the help. hopefully someone has some other ideas, or at least a way i can get more info about why OpenShot is terminating immediately.

peace

[Andy]

There is currently no other way of getting any debug info from running Openshot normally.

One way you could do it, and it depends on how comfortable you are with programming tools, is to use a Python IDE, such as WIngware or Eclipse and step through the code and find where it falls over.

Do you have the python-mlt bindings, I can't see them in your list?

One other idea is the version of libcairo. Some people on Ubuntu had a problem where they had updated libcairo (a dependency of goocanvas) from a PPA, with the result being that the version of cairo no longer matched the python bindings.

I am not sure that it is the solution for you, but it is a thing to try.
You could try to launch Openshot with Gdb and see if you have something in output.
You must install the dgb version of your python version (I think for you python2.6-dbg). AFter un the program under dgb and wait for the problem. And after see if you have something in the output. It is working like this :

Code: Select all

gdb python
(gdb) run openhsot.py

Think to put all the process.
When you have finished, and for quit the process, type Ctrl + D in your keyboard.
I don't know if you will have something in the output but it is something to try.

thanks again for the help. though i have not had time yet to step through the code, when running OpenShot in gdb, i got the following clue:

Code: Select all

(gdb) run /usr/bin/openshot
Starting program: /usr/bin/python2.6 /usr/bin/openshot
[Thread debugging using libthread_db enabled]
--------------------------------
   OpenShot (version 1.2.2)

Process no longer exists: 15878.  Creating new pid lock file.

Program received signal SIGSEGV, Segmentation fault.
0x00007fffef16a702 in uuid_generate_time () from /lib/libuuid.so.1


that library is from the util-linux package on Gentoo, but from the libuuid1 for Debian/Ubuntu. i have util-linux-2.17.2, with libuuid.so.1.3 installed, while the libuuid1 in karmic is 2.16-1ubuntu5.1, also with a libuuid.so.1.3. i am not sure if karmic is the version of Ubuntu that is needed by OpenShot, but the versions seem to be compatible.

i tried reinstalling the libuuid library, but still the same error, i.e. the segmentation fault with libuuid.

does this ring any bells? when i get some more time i will try a step through debugger and get more particulars.

thanks again.

I am having the same problem. I tried to install mlt .0.6.2 when everything when crazy. This is the error I get:
--------------------------------
OpenShot (version 1.3.0)
--------------------------------
Process no longer exists: 16495. Creating new pid lock file.
No formats or codecs were found. Please check the OpenShot preferences and configure the 'melt' command name.
state saved
Segmentation fault

[nixnine]

I've reinstalled everything but still the problem persists. I assume it was something that I did trying to upgrade mlt. But I've reinstalled all the files associated with that and melt. I'm very troubled because I love using openshot. I can so without the smooth scaling, but I need the program back.

I am using Linux Mint 9, BTW.

[nixnine]

I discovered the problem. Well, the solution, anyway. What I did was download the dependencies package and installed everything that was there. Then when I started Openshot, It actually started. So anyway, case solved for now.

Thanks.

[Cenwen]

Interesting feedback so we can have like conclusion (at first look) that when people have this message they miss them some dependencies.
Thanks a lot.

[nixnine]

Is there a way to install the newest version of MLT from a ppa? I've searched everywhere and can't seem to find one. I am running Mint 9 which is based on Lucid. Is there a way to install MLT on that version of Ubuntu? I did try compiling but did something wrong (see previous posts) and upset everything.


Thanks,
Nix

ahoy all,

as the one who started this thread, i am glad to say that i can finally run OpenShot 1.3.0 on Gentoo, using the ebuild found here https://bugs.gentoo.org/show_bug.cgi?id=283673 and i think the latest update of net-libs/gnutls-2.10.5. after installing that version of gnutls, OpenShot now runs. it could have been some other update, but i think we had tracked the bug down to a segfault in GNU TLS and that update seems to have fixed the issue.

thanks to everyone for all the help and the great application.

peace.
