Debug OpenLibrary(#PB_Any, "/Applications/VLC.app/Contents/MacOS/lib/libvlc.dylib")

Works with VLC 2.2.8, but don't work with the newest VLC 3.0.3

Any hints?

Have you tried this?

Code: Select all

SetEnvironmentVariable("VLC_PLUGIN_PATH", "/Applications/VLC.app/Contents/MacOS/plugins/")

With the correct path.

Yes. I set this. But the problem is the OpenLibrary command. It seems the library can not be opened.
With Windows it works. I can open the VCL-dll with OpenLibrary() for all versions...

I found this, but I don't know if it help:

The VLC distribution has changed the way it packages its dylibs, which affects the ability for the VLC plugin to load them.

`otool -L` output from VLC 2.2.8:
```
/Applications/VLC.app/Contents/MacOS/lib/libvlc.5.dylib:
@rpath/libvlc.dylib (compatibility version 12.0.0, current version 12.0.0)
@rpath/libvlccore.dylib (compatibility version 10.0.0, current version 10.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
```

`otool -L` output from VLC 3.0.0:
```
/Applications/VLC.app/Contents/MacOS/lib/libvlc.5.dylib:
@loader_path/lib/libvlc.5.dylib (compatibility version 11.0.0, current version 11.1.0)
@loader_path/../lib/libvlccore.8.dylib (compatibility version 9.0.0, current version 9.1.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
```

The change from `@loader_path` to `@rpath` now puts the burden on consumers of `libvlc.5.dylib` (read: OBS’ VLC plugin) to have set the `@rpath` (at compile time) to include the path to that dylib. VLC itself sets the `@rpath` appropriately from within the VLC application binary itself. This is possible because all the libraries are accessible relative to that binary.

It weird but I don't think it's a PB command problem as we just use the standard dlopen() call.

Same behaviour with 3.06.
It is impossible to open the VLC libvlc.5.dylib with PB since VLC version 3.x. Version 2.x works

otool -L /Applications/VLC.app/Contents/MacOS/lib/libvlc.5.dylib
/Applications/VLC.app/Contents/MacOS/lib/libvlc.5.dylib:

Code: Select all

Debug OpenLibrary(#PB_Any, "/Applications/VLC.app/Contents/MacOS/lib/libvlc.5.dylib") # = 4296235608
Debug OpenLibrary(#PB_Any, "/Applications/VLC3.app/Contents/MacOS/lib/libvlc.5.dylib") # = 0

Could you try by importing dlopen() ?

I gave this another try and now it works.

(Tutorial for dummies)
You have to do 2 things:
change the rpath of the lib to your path
set the plugin path at run time

To change the rpath assuming your lib is located at 'yourpath/lib/'
Open a terminal, and type:
cd yourpath/lib/
Then:
install_name_tool -change @rpath/libvlccore.dylib yourpath/lib/libvlccore.dylib yourpath/lib/libvlc.dylib

You only need to do this once, I guess you will need some kind of installation if you want to redistribute it.

Then this code should work:

Code: Select all

EnableExplicit

Define.s libVlc
Define.i hlib

libVlc = "yourpath/lib/libvlc.dylib"
SetEnvironmentVariable("VLC_PLUGIN_PATH", "yourpath/plugins/")

hlib = OpenLibrary(#PB_Any, libVlc)

Debug CallFunction(hlib, "libvlc_new", 0, #Null)

Tested with the last libvlc version.

Hi All

Trying to get Libvlc working.

using the following:-

Code: Select all

EnableExplicit

Define.s libVlc
Define.i hlib

libVlc = GetUserDirectory(#PB_Directory_Documents) + "VlcTRY/VLC.app/Contents/MacOS/lib/libvlc.dylib"
SetEnvironmentVariable("VLC_PLUGIN_PATH", GetUserDirectory(#PB_Directory_Documents) + "VlcTRY/VLC.app/Contents/MacOS//plugins/")

hlib = OpenLibrary(#PB_Any, libVlc)

Debug CallFunction(hlib, "libvlc_new", 0, #Null)

I get a large number in the debug window which I assume is correct.

How do I move on from this to play an audio file?
