To reproduce the crash:

$ export LD_LIBRARY_PATH=/usr/lib64/lives
(libweed.. and libOSC.. are installed in a private directory for me because of packaging issues)
$ lives-exe -debug

Try to load a video clip from Youtube, then Tools -->Preference.

[Salsaman]

I am unable to reproduce the bug here. Downloading from Youtube works fine, and opening Preferences after also works fine.

[Salsaman]

Something else just occured to me. You may need to edit your ~/.lives file and alter the value of <lib_dir> to point to /usr/lib64</lib_dir>

[Antonio Trande]

<lib_dir> already points to /usr/lib64 for me.

[Antonio Trande]

src/preference.c patched as asked in RPMFusion ticket:

Tools-->Preference problem is fixed already with line 1) proposed; patch used:

Do you also need to know how lines 2) and 3) work?

[Salsaman]

No, but please don't apply that as a fix, I need to make a change in lives_list_store_new(). Please hold.

[Antonio Trande]

Okay, no problem.

Also, I'm still seeing this warning:

No frei0r plugins found; if you have them installed please set the FREI0R_PATH environment variable to point to them.
LiVES info: No usable filters found in plugin /usr/lib64/lives/plugins/effects/realtime/weed/frei0r/frei0r.so

although I set FREI0R_PATH to /usr/lib64/lives/plugins/effects/realtime/weed/frei0r.

[Salsaman]

OK, please try this. Restore the line in preferences.c, then edit widget-helper.c.
Inside the function lives_list_store_new(), you should find two lines like:

  types[i]=va_arg(argList,int);

you only need to change the first one:

  types[i]=va_arg(argList, long unsigned int);

Hopefully this will fix the problem.

[Antonio Trande]

Works!

[Salsaman]

FREI0R_PATH should point to where the frei0r plugins are (not to where the LiVES frei0r wrapper is). So for example /usr/lib64/frei0r-1/

[Salsaman]

@Antonio:

What you should probably do is create a custom script /usr/bin/lives, eg:

export FREI0R_PATH=/usr/lib64/frei0r-1
export LADSPA_PATH=<path_to_ladspa_plugins>
/usr/bin/lives-exe</path_to_ladspa_plugins>

Then in the package replace the symlink /usr/bin/lives with your script.

[Antonio Trande]

Does exist an env variable for libvisual plugins ?

LiVES info: No usable filters found in plugin /usr/lib64/lives/plugins/effects/realtime/weed/libvisual/libvis.so

[Salsaman]

Antonio, can you please apply the patch here: https://sourceforge.net/p/lives/code/2353/

re. libvisual path, I am looking into this.

[Antonio Trande]

Do you mean that I should compile revision r2352 by applying this patch?

[Salsaman]

No. You should apply this patch: https://sourceforge.net/p/lives/code/2353/

[Antonio Trande]

Patch applied; LiVES compiled fine, Tools->Preference menu does NOT crash.

[Salsaman]

You can apply this second patch: https://sourceforge.net/p/lives/code/2354/tree//trunk/lives-plugins/weed-plugins/libvis.c?diff=505487e4bfc09e4ced4d35a9:2353 which will allow setting of VISUAL_PLUGIN_PATH (a : delimited string of additional directories to check).

[Antonio Trande]

I have applied patches from commits 2353,2354; LiVES compiled and executed by

$ export LD_LIBRARY_PATH=/usr/lib64/lives FREI0R_PATH=/usr/lib64/frei0r-1 LADSPA_PATH=/usr/lib64/ladspa VISUAL_PLUGIN_PATH=/usr/lib64
$ lives-exe

VISUAL_PLUGIN_PATH points to the libvisual-0.4.so.0.0.0 location.

Unfortunately, still appears this warning:

[Salsaman]

VISUAL_PLUGIN_PATH needs to point to the location of the libvisual plugins (not the libvisual library).

[Antonio Trande]

libvisual-plugins are not in Fedora by long time but I have discovered this just now. And the projectM visualization plugin for libvisualis not compatible.

I think that libvisual support must be disabled too.

[Salsaman]

OK.

[Salsaman]

Closing, fixed.
