Just made some updates to the PKGBUILD and can confirm it builds cleanly in a chroot. The libcaca issue should be resolved now since upstream merged in their changes to caca.c about a month ago (from today/this comment date). Let me know if there's any issues and I greatly appreciate the patience in my response!

The package currently does not compile:

What to do?

UPDATE: According to https://code.videolan.org/videolan/vlc/-/issues/26389, this is due to libcaca being too new. This error occurs with libcaca-0.99beta-20.

I get the same compile error that Wennadocta has, but regarding koynoyno's workaround uninstalling either version of Lua on my system is not an option, as I have essential software that requires either.

@andrewSC:

The following error related to pl_filter_haasnsoft is due to libplacebo upstream accidentally pulling the filter [1]. 

While reading through [1], I am not fully sure if it really was an accident. The problem admitted was that the haasnsoft filter was pulled without a previous deprecation warning. For now, it has been re-introduced in trunk but it remains deprecated:

extern const struct pl_filter_config pl_filter_haasnsoft PL_DEPRECATED;

Next, thanks a lot for your help with libplacebo-git:

You need to build `libplacebo-git` and install it in the chroot before building `vlc-git`. Here's a super quick update I did to the `PKGBUILD` [2] to get `libplacebo-git` to build (aur version was not building for me).

Meanwhile, the libplacebo-git maintainer has listened to feedback from comments and has separated the libplacebo-git 32 bit version from the 64 bit version. However, there are still a few things to be taken into consideration.

First, there seems to be a new dependency spirv-cross that needs to be included as otherwise, you get

Run-time dependency spirv-cross-c-shared found: NO (tried pkgconfig and cmake)

trying to build libplacebo-git. Next, there is

../libplacebo/src/meson.build:48:0: ERROR: C shared or static library 'version' not found

That can apparently be avoided by disabling d3d11 in the meson options in the PKGBUILD. See my comment to [2].

Once the next libplacebo release is cut, libplacebo-git shouldn't have to be built in order for this package to build correctly.

That commit was made on 06 May already,and it appears to be still not included in libplacebo releases :(

[1] https://github.com/haasn/libplacebo/commit/5a31ece1363c870071d1e13a5efe6956220380de [2] https://gist.github.com/andrewSC/6acfca87db8ed269f9a6b59d1c3f6a0e

Wennadocta, I had the same build error. I checked lua packages and turns out I have lua and lua52. Removing lua52 helped.

Installing the libplacebo-git package fixed the missing pl_filter_haasnsoft filter issue for me Thanks to andrewSC for pointing that out

Indeed, the ffmpeg-git conflict comes from chromaprint. It has to be replaced by chromaprint-fftw.

Reason why I wanted to install ffmpeg-git: The ffmpeg packages in the official repository come without support for vaapi and vdpau - in order to have this support enabled, ffmpeg has to be compiled with

--enable-vaapi
--enable-vdpau
--enable-hwaccel=h264_vdpau
--enable-postproc

(Sources: https://wiki.videolan.org/VLC_VAAPI/ and https://stackoverflow.com/questions/23289157/how-to-use-hardware-acceleration-with-ffmpeg)

With the standard ffmpeg package, VLC has problems using vdpau:

[h264 @ 0x7fd158012240] Failed setup for format vdpau: hwaccel initialisation returned error.

Furthermore, AV_PIX_FMT_VAAPI_VLD is deprecated (source: ffmpeg documentation, APICHANGES):

2015-08-19 - 9f8e57ef - lavu 54.31.100 - pixfmt.h
  Add a unique pixel format for VA-API (AV_PIX_FMT_VAAPI) that
  indicates the nature of the underlying storage: a VA surface. This
  yields the same value as AV_PIX_FMT_VAAPI_VLD.
  Deprecate old VA-API related pixel formats: AV_PIX_FMT_VAAPI_MOCO,
  AV_PIX_FMT_VAAPI_IDCT, AV_PIX_FMT_VAAPI_VLD.

Hence, it might make sense to apply this change to the VLC sources:

find . \( -type d -name .c -prune \) -o -type f -print0 | xargs -0 sed -i 's|AV_PIX_FMT_VAAPI_VLD|AV_PIX_FMT_VAAPI|g'

Why does this package conflict with ffmpeg-git?

It.. doesn't? Where do you see the conflict explicitly? The PKGBUILD doesn't explicitly list a conflicts with ffmpeg-git.

Fails to compile

I was able to compile 03674aee047f5b9e41d6f267592f79c7790326b1 in a chroot, following the instructions I provided, without issue. Given the pathing of the error message i'm suspicious if it's not an out-of-date dep on your system.
