According to Google, several people are having this issue:
$ sudo dnf install --allowerasing avidemux
Last metadata expiration check performed 0:14:07 ago on Thu Nov 19 00:32:09 2015.
Error: nothing provides libx264.so.142()(64bit) needed by avidemux-qt-2.6.8-3.fc22.x86_64
(Note that this is on F23)
Has anyone solved it, or do we just have to wait for RPMfusion to get
their act together?
