--- Comment #10 from Potomac <mister.freeman@laposte.net> ---
Created attachment 94325

adding XInitThreads(), #include <X11/Xlib.h> and a link to X11 library

I did your modifications ( adding XInitThreads(), #include <X11/Xlib.h> ), I
had to add a link to X11 library in /src/kaffeine/src/CMakeLists.txt,

I put these modification in a patch ( see the attachment ),

it solves the error message related to libvlc, but there are some problems :

- at start I can see the image for a channel,
- but it's impossible to change a channel, I get a black screen,
- randomly the CPU usage can be very high ( 56% instead of 5% )
- when I close kaffeine I get a crash, a segmentation error :

Application: Kaffeine (kaffeine), signal: Segmentation fault
