OpenLP not detecting vlc on Mac

raoul

Jamie Hockin What's weird about your solution is that it doesn't use the VLC app's location either...

vlc_dir = AppLocation.get_directory(AppLocation.AppDir) / 'vlc.app/Contents/MacOS'

In this case, AppLocation.get_directory(AppLocation.AppDir) actually points to OpenLP's app directory (specifically, the top level OpenLP.app, if I remember correctly). So the path in your example above literally does not exist.

When I changed the location to point to /Applications/VLC.app/... it throws an error about not being able to look up the other library bundled with VLC.

Additionally, if that file does not exist, then OpenLP lets the python-vlc do the lookup automatically. So in theory, it should work on anyone's computer that has VLC installed in the /Applications directory.

Jamie Hockin

raoul It works for me because OpenLP and VLC are both in /Applications. The existing code is no better at finding VLC, though.
I see now that it's not a good solution. So the question is why python-vlc doesn't take care of it on my Mac. I suppose I could just hack the code with any new version of OpenLP that doesn't find VLC. I'm not going to worry about it any more, since the church installation uses Windows and it works fine.

The current vlc.py module from vidoelan seems to have some uncertainty about finding libvlc.dylib.
From https://git.videolan.org/?p=vlc/bindings/python.git;a=tree;f=generated;b=HEAD
elif sys.platform.startswith('darwin'):# FIXME: should find a means to configure path
d = '/Applications/VLC.app/Contents/MacOS/'
c = d + 'lib/libvlccore.dylib'
p = d + 'lib/libvlc.dylib'
if os.path.exists(p) and os.path.exists(c):
# pre-load libvlccore VLC 2.2.8+ ctypes.CDLL(c) dll = ctypes.CDLL(p) for p in ('modules', 'plugins'): p = d + p if os.path.isdir(p): plugin_path = p break else: # hope, some [DY]LD_LIBRARY_PATH is set...# pre-load libvlccore VLC 2.2.8+
ctypes.CDLL('libvlccore.dylib')
dll = ctypes.CDLL('libvlc.dylib')
`
The developers' default for MacOS is to expect VLC to be installed in the /Applications directory. The OpenLP code is simpler, but seems to expect that the OS knows where the dylib is. Perhaps just ask Mac users to install VLC in Applications and look for it there. Very few Mac users are going to be able or interested to add a path to VLC.

Hey @Jamie Hockin I just uploaded new builds of OpenLP, which I hope will fix the VLC issue. I didn't get the "VLC is not installed" error message (which I was getting before), but I didn't fully test out video either.

Intel Processor
Apple Processor

Let me know if this build works.

raoul I installed this build and I get the message that this application is not supported on this Mac. MacBook Air Quad Core I7

funkydan2

Just tested that dev version on my Intel Macbook Air - works for me. Well done!

No error message about VLC
Audio with song lyrics (backing tracks) work
Video worked

Jamie Hockin

Thanks @raoul
I installed the Intel build as a test user (on it's desktop) and media worked perfectly. The brilliant thing about using VLC is that you can get it to play anything. In my case, it was a .mkv file created by OBS Studio.

Jamie Hockin

oleydad with the Intel processor link? I had no problem on my iMac quad core i7

oleydad

Jamie Hockin Yes the intel link above did not work for me. I did notice in discussion below that version 3.12 was available for Mac intel. I upgraded to that and all is well. Thanks,

Hi there. I'm new to Open LP, and I'm a MAC user, so ya know I don't get a lot of practice with open source platforms. I am loving Open LP!

In case others are watching this thread, I did get the VLC error when I frist downloaded it Open LP, and I've had VLC for a long time. So, I did update VLC to the 3.0.2, since i hadn't installed a new version in a long time. I deleted my old version and installed the 3.0.2 (which is the current one I see when I go to their site)

I attempted to download the link that Raoul posted (Love the tutorial series, by the way!). But, I did not at first delete the previously installed version, so the new one came into applications as Open LP 2, which meant that the code in the terminal wouldn't direct correctly. I attempted to be clever and alter the command, but that didn't work. I'm sure I didn't do it correctly. But, anyhow. I deleted the first version of Open LP. Then I downloaded the Intel version linked here by Raoul. Put the command in the terminal, opened it, and it verified VLC like a dream.

Bonus, in the newly downloaded Open LP, it had the services and songs I had already worked on (which, granted, wasn't much, because I'm new, but was nice to see it import seamlessly).

I'm really amazed. Thank you, Raoul, for the hard work, and thank you Jamie Hockin as well.

Lynaya Version 3.1.2 fixes this problem and is now the version you get on the OpenLP site.

Lynaya

Hey Jamie. I hope you mean as of today. Because I downloaded off the main site last night, and I got the error with VLC. But I’m sure that’s what you mean. Thanks!

Jamie Hockin

Lynaya I think it just changed this morning. It solves a number of issues for us. Probably the most exciting is that image thumbnails can now be much larger, which is great for one visually impaired parishoner who uses a tablet to follow the service.

Unfortunately it was the update to 3.1.2 that cause this message to appear for us.

Downgrading VLC to 3.0.2 hasn't worked, nor has any version between that one and the latest.

Would it be worth having a picker in the settings window to allow us to pick VLC's app folder location, or even libvlc.dylib directly?

Jamie Hockin

Are VLC and OpenLP both installed in /Applications?

DBCTech

Jamie Hockin Yep, both are in the Applications.

I have actually just fixed it. I'm working with an M2 Mac mini. Downloaded both the intel and apple silicon versions of VLC. Swapping from AS to intel and then back to AS, opening VLC in between each time seems to have fixed the issue. OpenLP now recognises VLC and will playback videos.

DBCTech any love for those of us still using Intel Macs? I'm having no luck whatsoever, everything's up to date, in the Applications folder, everything. It makes no sense.

raoul

Valera1865 The OpenLP team keeps an Intel Mac for this exact reason. When I tested 3.1.2 with VLC on the Intel Mac, it was working. Make sure you're using the OpenLP version for Intel Macs, as well as the VLC version for Intel Macs.

Valera1865

raoul I just reinstalled OpenLP and it finally worked. I'm not sure what the issue was but it's resolved now.

Confirmed 3.1.2 appears to find VLC properly on macOS 14.5, both Intel and Apple Silicon. No error message. Woo hoo!
