Right. I just reproduced this multiple times. VLC is not installed, nor is libvlc.
>From the Python 3 console, I can import openlp.core.ui.media.vendor.vlc without a problem, but try to do anything and it fails. So we need to actually just try to do something (like get VLC's version) and use that to determine if VLC is installed or not. -- You received this bug notification because you are a member of OpenLP Core, which is subscribed to OpenLP. https://bugs.launchpad.net/bugs/1589675 Title: OpenLP on Linux crashes on startup when VLC not installed Status in OpenLP: Confirmed Bug description: Similar to bug #966086 **OpenLP Bug Report** Version: {'build': None, 'version': '2.4.1', 'full': '2.4.1'} --- Details of the Exception. --- this occurred as OpenLP was opened --- Exception Traceback --- Traceback (most recent call last): File "/usr/bin/openlp", line 44, in <module> main() File "/usr/share/openlp/openlp/core/__init__.py", line 391, in main sys.exit(application.run(qt_args)) File "/usr/share/openlp/openlp/core/__init__.py", line 142, in run Registry().execute('bootstrap_initialise') File "/usr/share/openlp/openlp/core/common/registry.py", line 137, in execute result = function(*args, **kwargs) File "/usr/share/openlp/openlp/core/lib/pluginmanager.py", line 60, in bootstrap_initialise self.hook_media_manager() File "/usr/share/openlp/openlp/core/lib/pluginmanager.py", line 122, in hook_media_manager plugin.create_media_manager_item() File "/usr/share/openlp/openlp/core/lib/plugin.py", line 204, in create_media_manager_item self.media_item = self.media_item_class(self.main_window.media_dock_manager.media_dock, self) File "/usr/share/openlp/openlp/plugins/media/lib/mediaitem.py", line 58, in __init__ super(MediaMediaItem, self).__init__(parent, plugin) File "/usr/share/openlp/openlp/core/lib/mediamanageritem.py", line 82, in __init__ self.setup_item() File "/usr/share/openlp/openlp/plugins/media/lib/mediaitem.py", line 90, in setup_item self.media_controller.setup_display(self.display_controller.preview_display, False) File "/usr/share/openlp/openlp/core/ui/media/mediacontroller.py", line 322, in setup_display player.setup(display) File "/usr/share/openlp/openlp/core/ui/media/vlcplayer.py", line 157, in setup display.vlc_instance = vlc.Instance(command_line_options) File "/usr/share/openlp/openlp/core/ui/media/vendor/vlc.py", line 1411, in __new__ return libvlc_new(len(args), args) File "/usr/share/openlp/openlp/core/ui/media/vendor/vlc.py", line 3630, in libvlc_new ctypes.c_void_p, ctypes.c_int, ListPOINTER(ctypes.c_char_p)) File "/usr/share/openlp/openlp/core/ui/media/vendor/vlc.py", line 246, in _Cfunction raise NameError('no function %r' % (name,)) NameError: no function 'libvlc_new' --- System information --- Platform: Linux-4.2.0-36-generic-i686-with-Ubuntu-15.10-wily Desktop: GNOME --- Library Versions --- Python: 3.4.3+ Qt5: 5.4.2 PyQt5: 5.4.2 QtWebkit: 538.1 SQLAlchemy: 1.0.8 SQLAlchemy Migrate: - BeautifulSoup: 4.3.2 lxml: 3.4.4 Chardet: 2.3.0 PyEnchant: 1.6.6 Mako: 1.0.2 pyICU: - pyUNO bridge: 5.0 VLC: - To manage notifications about this bug go to: https://bugs.launchpad.net/openlp/+bug/1589675/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~openlp-core Post to : openlp-core@lists.launchpad.net Unsubscribe : https://launchpad.net/~openlp-core More help : https://help.launchpad.net/ListHelp
