Arch Linux User Repository

Arch Linux split the vlc package between it's plugins.

This package has been refactored to only replace vlc-plugin-lua, updating will require manual intervention:

• Install vlc (and libvlc)
• Build the PKGBUILD and install vlc-plugin-luajit
• Install vlc-luajit

I missed the change done upstream by Arch, pushed the changes. Note that I also ignore Manjaro-related comments since I only support Arch Linux.

Here's an even easier way to get my build...

Copy the code below and save to fixit.patch (this will create the nfs_fix.patch file as well as patch your PKGBUILD to include it all in one simple git apply fixit.patch step):

git apply fixit.patch
makepkg -s

See my previous comment for more of an explanation of what gets changed...

Hi All, @tytan652,

So while I'm no C expert I did dig around in the VLC git repository and looked at modules/access/nfs.c and it does look like there was a commit in the master branch that was related to a change introduced in libnfs 6.0.0:

https://code.videolan.org/videolan/vlc/-/commit/a945944c2d50cacfacdd5b16d4ea5e7b4766a9fc

If you pay attention to line 212 through 220 (in the linked commit above) there is a new #ifdef LIBNFS_API_V2 that uses a modified call to nfs_read_async which is the error in everybody's failed compile.

Here are the changes:

#ifdef LIBNFS_API_V2
    p_sys->res.read.p_buf = NULL;
    if (nfs_read_async(p_sys->p_nfs, p_sys->p_nfsfh, p_buf, i_len, nfs_read_cb,
                       p_access) < 0)
#else
    p_sys->res.read.p_buf = p_buf;
    if (nfs_read_async(p_sys->p_nfs, p_sys->p_nfsfh, i_len, nfs_read_cb,
                       p_access) < 0)
#endif

There were other changes to nfs.c in the master branch that will break the build in other ways. I managed to get a working build of this vlc-luajit package by adding the following nfs_fix.patch to my build directory along side the PKGBUILD file (luckliy the PKGBUILD applies every .patch file in the same directory). However, you will have to add the nfs_fix.patch file as a source to your PKGBUILD.

Here are my changes that yield a successful build:

DISCLAIMER: I can only confirm that this fixes the build as it uses the new calling convention for nfs_read_async. I cannot confirm that the nfs plugin (modules/access/nfs.c) functions 100% correctly.

Until @tytan652 gets a chance to review the changes in the upstream source this might be a way to get a build on your machine. Thank you @tytan652 for all of your efforts with maintaining these packages. I know I have used them for quite some time to get a really nice custom build of obs-studio that has all of the bells and whistles that I like! To the community: I hope this helps somebody else!

sources/vlc-luajit/src/vlc-3.0.21/modules

libvlc-luajit should just become Optional dependency, because it's nothing but a problematic package that always fails to compile. It NEVER compiles successfully.

yeah this version disable vaapi, make hevc impossible to play with old intel laptops. is there a flag or a way to enable it?

it seems like this version has to use my CPU for video decode, i think i saw a comment below about this version not containing vaapi (i have amd gpu)

latest version freezes after a few seconds of playing any video any codec any format

You are likely not using the official libplacebo package which is version 5 on Arch repo.
