Oh, I did not know, I will wait until its available in the repositories and fix it.

The official vlc in "extra" repo is still of version 3.x (3.0.21-6) and webcamoid builds properly, Are you sure you have installed the version 4.0 of vlc? It is available only in AUR as vlc-git. And it is apparently not backward compatible which is illustrated by errors in my previous post. If so, you should exclude "vlc-git" from dependencies, or check if the version 3.x is installed, not 4.x.

I have updated my system, did checked and its building fine for me without any change. papavlos maybe your system was not fully updated when building the package?

hipersayan_x commented on 2024-10-02 13:42 (UTC)

Ok, I usually do not update my system before a release that's why I did not have the build error, will check.

papavlos commented on 2024-10-02 13:01 (UTC)

I know the reason: I have installed in my system the vlc-git 4.0.0 (Qt6 based). instead of vlc 3.0.21 (Qt5 based). That's why all errors were due to incompatibility with vlc headers... After downgrading to vlc 3.x - webcamoid was built and installed without further issues. Case closed.

@hipersayan_x I have more carefully reviewed output of makepkg -sL command. I have found some errors. Only a few of them because of 5000 limitation:

@papavlos, I need the full error message.

I am getting a blank screen on one of the machines on which I am trying this package. However I have two more laptops on which the package is working as intended.

On the host where the package gives a blank screen, the flatpak (currently at version 9 of webcamoid and relying on deprecated flatpak frameworks) works fine.

Hence, I suspect this is no hardware issue, but a dependency problem: the packages on the machine where the package fails are probably not perfectly aligned with the packages on the other machines where it works. So there may be something that should be installed, that I do not have and that is not listed as a dependency.

Anyone else experiencing something similar? Any clue.

As an additional issue, on all the machines I have, selecting "screen" as the source causes the application to freeze (but this is probably an application bug).

This package fails to build without ffmpeg4.4.

Please change ffmpeg to ffmpeg4.4 and add export PKG_CONFIG_PATH='/usr/lib/ffmpeg4.4/pkgconfig' before you call CMake.

It should look like this:

build() {
    cd "$srcdir/${pkgname}-${pkgver}"
    export PKG_CONFIG_PATH='/usr/lib/ffmpeg4.4/pkgconfig'
    cmake \
        -DCMAKE_BUILD_TYPE=Release \
        -DCMAKE_INSTALL_PREFIX=/usr \
        .
    make $MAKEFLAGS
}
