Description aslanex 2015-11-01 15:13:27 UTC 
Basic audio effects (Fade in, Fade out, Gain, Volume with keyframes) are completely missing. Reinstall of Kdenlive, Frei0r or MLT does not help.

Reproducible: Always
Comment 1 aslanex 2015-11-06 19:37:21 UTC 
Seems the problem is connected with MLT 0.9.8.
Comment 2 Vincent PINON 2015-12-06 13:25:10 UTC 
Hello,
Sorry for late reply...
Volume is a basic component part of MLT.
Aren't you pointing to a wrong MLT installation through environment variable or ~/.config/kdenliverc (maybe try to rename that file to retry from scratch).
Comment 3 aslanex 2015-12-06 15:33:37 UTC 
I am not able to fully reproduce the bug, since I have installed Ubuntu 14.04 in order to make it working. But the same happens when I use Kdenlive 0.9.10 and manually update MLT to 0.9.8.
Comment 4 Vincent PINON 2015-12-06 16:24:54 UTC 
How do you update MLT?
Building the source by yourself? Does then kdenlive use your build? (see ldd kdenlive output)
Picking a .deb from higher distribution version? If so, beware that MLT can then be linked with different libraries version, and so fail to load most things...
Comment 5 aslanex 2015-12-06 16:38:31 UTC 
Oh sorry. I've tried building version 0.9.6 and 0.9.8 from source. After reboot, Kdenlive started using it (I could see the correct version in the configuration Wizard) and these effects were missing. Nothing another changed.
It could be solved by completely removing MLT and Kdenlive and installing it again from Sunab's repository.
Comment 6 Vincent PINON 2015-12-06 17:55:46 UTC 
When you build MLT from source, do you add flag --enable-gpl and --enable-gpl3 ?
Because volume filter is GPL, but by default MLT enables only LGPL modules.
Comment 7 aslanex 2015-12-08 20:52:18 UTC 
Yes, it works well now. Thanks for the solution and sorry I am not able to help with the Ubuntu 15.10 problem now.

This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
