Crash with ¨Nervous¨ effect

[Joop Mevissen]

Adding the Nervous effect results in a segfault when trying to play that clip:

--------------------------------
   OpenShot (version 1.1.0~alpha2)
--------------------------------
project modified: Added effect frei0r.nervous
state saved
on_tlbPlay_clicked called with self.tlbPlay
GenerateXML for an Effect
Segmentatiefout

[Jonathan Thomas (jonoomph)]

This effect crashes for me also. Does this work for anyone? Is it supported in all versions of Frei0r?

[Andy Finch (fincha)]

It doesn't crash for me (32 bit 9.04), but it also doesn't seem to do a lot either.

[hva (francesco-hermanitosverdes)]

It works for me with development version of Frei0r (amd64 ubuntu 8.04)

[Olivier Girard (eolinwen)]

It crashs for me when i want to play with the preview. I'll be back now on
my karmic, it was unicap who was crashing the system and was shutdowning it
(in fact it was the documentation of unicap).

The update of the POT file is good for me. [?]

Cheers Olivier

i have done another test with gdb activated. It crashed but not in playing with the preview . Just when i added the effect, immediately. I joint a screenshot and the backstrass of gdb. It seems to be a error of libmlt.1.so

I wonder if this effect has recently added some new parameters, or
removed some parameters. Maybe depending on which version of Frie0r
we are using, determines whether it will crash MLT or not.

I checked if it played with melt like this:

melt -filter frei0r.nervous test006.dv

It doesn´t crash but there is no effect visible.

I forgot to mention I am on 32-bit Ubuntu 9.10, frei0r version 1.1.22git20090409+repack-0ubuntu1.
If I look in /usr/lib/frei0r-1 I see no nervous plug-in?

[Jonathan Thomas (jonoomph)]

This nervous effect is making me nervous. If it has no visible
effect, should we just remove it to prevent crashes on some systems?
Thanks.

[Andy Finch (fincha)]

Yes I think we should. We should also think about removing the Water effect too, which also causes crashing on some systems (see Bug #505136).

[Olivier Girard (eolinwen)]

Good suggestion.

[hva (francesco-hermanitosverdes)]

I suppose this could have to do with problem with nervous effect:
http://git.dyne.org/index.cgi?url=frei0r/commit/&id=8149fae6884035aa588eb14eb228863ebbd6bdbf

the fix didn't get in ubuntu frei0r package, this could explain why the filter is functional with git dev version of frei0r.
The frei0r package in ubuntu hasn''t been updated since september 4th 2009, and the same package is getting into lucid.

[hva (francesco-hermanitosverdes)]

there's the possibility that Nervous effect is not even present in Ubuntu packages, as the last sync to git repository made by debian package maintainers date to april 2009, and Nervous effect has been introduced in August.
Sorry, it's my fault, as I was using all the dependencies compiled from development sources I didn't check which effect was in official packages.

[Joop Mevissen (jm)]

Thanks for checking! After installing the latest version of Frei0r it works. But I also think it is best just to remove it for now.

[Jonathan Thomas (jonoomph)]

I have removed this effect from the trunk. Thanks!

[ptf (paul-flinders)]

Of course the "fix" doesn't fix the real bug.

The real bug is that MLT segfaults if you ask it to apply a frei0r filter which doesn't exist, this should probably be reported to the MLT guys.

There is also an opehshot bug; Only configured effects/filtered should be offered and a warning should be given if a project which refers to an invalid filter is loaded.

[moimael (moimael)]

Can we mark this bug as released ?

[Jonathan Thomas (jonoomph)]

Yes, I think this effect has been removed.
