Merge lp:~trb143/openlp/no_vlc into lp:openlp

[Tim Bentley]

This is for testing on different configurations.
media.vendor.vlc has been removed and python3-vlc installed in its place.

Works on Fedora

[Raoul Snyman (raoul-snyman)]

Linux tests failed, please see https://ci.openlp.io/job/MP-02-Linux_Tests/148/ for more details

[Raoul Snyman (raoul-snyman)]

Linux tests failed, please see https://ci.openlp.io/job/MP-02-Linux_Tests/149/ for more details

[Raoul Snyman (raoul-snyman)]

There's just one test failing, now that I have installed python-vlc on the server, can you take a look please?

-to create a libvlc instance.  From this instance, you then create
-L{MediaPlayer} and L{MediaListPlayer} instances.

-Alternatively, you may create instances of the L{MediaPlayer} and

-    @note
-    LibVLC may create threads. Therefore, any thread-unsafe process
-    initialization must be performed before calling L{libvlc_new}(). In particular
-    and where applicable:
-    - setlocale() and textdomain(),
-    - setenv(), unsetenv() and putenv(),
-    - with the X11 display system, XInitThreads()
-      (see also L{libvlc_media_player_set_xwindow}()) and
-    - on Microsoft Windows, SetErrorMode().
-    - sigprocmask() shall never be invoked; pthread_sigmask() can be used.
-    On POSIX systems, the SIGCHLD signal B{must not} be ignored, i.e. the
-    signal handler must set to SIG_DFL or a function pointer, not SIG_IGN.
-    Also while LibVLC is active, the wait() function shall not be called, and
-    any call to waitpid() shall use a strictly positive value for the first
-    parameter (i.e. the PID). Failure to follow those rules may lead to a
-    deadlock or a busy loop.
-    Also on POSIX systems, it is recommended that the SIGPIPE signal be blocked,
-    even if it is not, in principles, necessary, e.g.:
-    @code
-    @endcode
-    On Microsoft Windows Vista/2008, the process error mode
-    SEM_FAILCRITICALERRORS flag B{must} be set before using LibVLC.
-    On later versions, that is optional and unnecessary.
-    Also on Microsoft Windows (Vista and any later version), setting the default

-    @code
-    @endcode.

-    @param argv: list of arguments (should be None).
-    @return: the libvlc instance or None in case of error.
-    @version Arguments are meant to be passed from the command line to LibVLC, just like VLC media player does. The list of valid arguments depends on the LibVLC version, the operating system and platform, and set of available LibVLC plugins. Invalid or unsupported arguments will cause the function to fail (i.e. return None). Also, some arguments may alter the behaviour or otherwise interfere with other LibVLC functions. @warning There is absolutely no warranty or promise of forward, backward and cross-platform compatibility with regards to L{libvlc_new}() arguments.
