I am having an error after updating my packages which include mlt.

$ rpm -q mlt
mlt-0.9.6-3.el6.nux.x86_64

The error that I am having is:

$ mlt-melt -version
mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so
(/usr/lib64/libavfilter.so.5: undefined symbol: ass_set_shaper)

Other information:

$ rpm -qf /usr/lib64/mlt/libmltavformat.so
mlt-0.9.6-3.el6.nux.x86_64

$ rpm -qf /usr/lib64/libavfilter.so.5
ffmpeg-libs-2.6.8-3.el6.nux.x86_64

I can't replicate this.

Can you do a "yum clean all; yum reinstall mlt ffmpeg-libs" ? Just to make sure you have the right stuff.

<mock-chroot>sh-4.1# rpm -q mlt
mlt-0.9.6-3.el6.nux.x86_64
<mock-chroot>sh-4.1# 
<mock-chroot>sh-4.1# mlt-melt -version
No LADSPA plugins were found!

Check your LADSPA_PATH environment variable.

Unfortunately it is still the same.

In search for a solution for this problem, I stumbled upon on how to test for the presence of mlt in python. I do hope the following info would help:

$ python
>>> import mlt
>>> mlt.Factory().init()
mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so
(/usr/lib64/libavfilter.so.5: undefined symbol: ass_set_shaper)
<mlt.Repository; proxy of <Swig Object of type 'Mlt::Repository *' at 0x7f13b9efb270> >

Listing python modules yields:

>>> sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()])
['argparse==1.2.1', 'beaker==1.3.1', 'cas==0.15', 'cups==1.0', 'cupshelpers==1.0', 'distribute==0.6.10', 'ethtool==0.6', 'firstboot==1.110', 'httplib2==0.7.7', 'iniparse==0.3.1', 'iotop==0.3.2', 'iwlib==1.0', 'mako==0.3.4', 'markupsafe==0.9.2', 'mutagen==1.16', 'nose==0.10.4', 'numpy==1.4.1', 'openshot==1.4.3', 'ordereddict==1.2', 'paramiko==1.7.5', 'pil==1.1.6', 'pip==7.1.0', 'pycrypto==2.0.1', 'pycurl==7.19.0', 'pygpgme==0.1', 'python-dmidecode==3.10.13', 'python-meh==0.11', 'pyxdg==0.18', 'reportlab==2.3', 'scdate==1.9.60', 'setuptools==0.6rc11', 'slip==0.2.20', 'smbc==1.0', 'urlgrabber==3.9.1', 'virtinst==0.600.0', 'yum-metadata-parser==1.1.2', 'zenmap==5.51']

This is from my EL6 home desktop, still cant replicate:

Not sure if that LADSPA_PATH is of any importance, though.

May I know the result of your "yum list gstreamer-plugins*"?

Here is mine:

gstreamer-plugins-bad.x86_64 0.10.22-2.el6.nux @nux-dextop
gstreamer-plugins-bad-free.i686 0.10.19-3.el6_5 @updates

gstreamer-plugins-bad-free-extras.x86_64 0.10.19-3.el6_5 @base
gstreamer-plugins-bad-nonfree.x86_64 0.10.18-1.el6.nux @nux-dextop
gstreamer-plugins-base.i686 0.10.29-2.el6 @base
gstreamer-plugins-base.x86_64 0.10.29-2.el6 @base
gstreamer-plugins-good.x86_64 0.10.23-3.el6 @base
gstreamer-plugins-ugly.x86_64 0.10.18-3.el6.nux @nux-dextop

Since the problem can't be reproduced, I am thinking of conflicting packages.

This is what I get when listing codecs of melt.

$ mlt-melt -query "video_codecs"
mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so
(/usr/lib64/libavfilter.so.5: undefined symbol: ass_set_shaper)
# No video codecs - failed to load avformat consumer

$ mlt-melt -query "audio_codecs"

(/usr/lib64/libavfilter.so.5: undefined symbol: ass_set_shaper)
# No audio codecs - failed to load avformat consumer

$ mlt-melt -query "formats"

Try to remove the ffmpeg and gstreamer packages altogether, perhaps there is some leftover stuff from some other repo or who knows.
