Hum i'm not you and what do you want to do with . But i believe that you have a project to realise so here what i recommande you. Desinstall the last kdenlive version (0.76)and his "dependencies". Desactive the repositorie corresponding. Reinstall openshot, kdenlive, the official works normaly (0.75), devede and all the softwares which have some problems with this ffmpeg version. The purpose is to have a fonctionnaly ffmpeg version with all (the major part)your software. The differencies between the 0.75 and the 0.76 are not so "important" than you can have a system working properly. So you can "play" (=work) with (and wtih kdenlive too) and create your project. After you could choose between only the last version kdenlive and the rest. I'm not sure that you haven't another problems with others softwares and this spécial ffmpeg version.
Thanks Olivier
