Arch Linux User Repository

This appears to no longer build due to the renaming of obs-ndi to distroav as requested I believe by the OBS project itself. Also the AUR package obs-ndi does not appear to work with the NDI 6 SDK..

I was able to get this AUR package to build (and work successfully with the NDI 6 SDK) by making the following changes:

This package now seems to be failing on ArchLinux (due to what appears to be a qt dependency):

Ok, I finally figured it out.

I had my color space in the advanced settings of OBS set to Rec. 709 because it provides extra brightness to the image. On versions of OBS prior to 28.0.0 this is handled gracefully, but on OBS version 28.0.0 or later it causes the green tint.

In all honesty, I'd prefer using 709, bur I guess going back to Rec. 601 is an acceptable workaround.

Aside from that, everything else is working as it should without any problems.

@RAMChYLD package is now building from the rewrite branch. let me know if there's any issues. to use ndi5 install ndi-sdk.

as for the green tinting issue, i'm not sure what the exact problem is however it's not present in obs-studio-git so i'd recommend using that.

OBS-NDI now has a git branch that works with OBS versions 28 and newer called "rewrite". Can you consider switching obs-ndi-git to that branch now that OBS 28 is live on Arch? The only catch is that it requires NDI 5.5 or newer which can be attained for free if you sign up to download the SDK.

Also, I'm having trouble in that the git branch is transmitting a very strong green tint on Arch. I've filed a bug report, but can anyone try and corroborate that this is also happening to them?

Edit: Nevermind, upgraded my Windows desktop to 28.0.2, libndi 5.5.1 and the rewrite git version of OBS-NDI and I'm also getting a green tint. I'm not having a good day. Downgrading the OBS-NDI and OBS but not the libndi restores usability, so it's an issue localized to OBS and OBS-NDI and not libndi.

@mattboy9921 so currently obs-ndi is broken for obs versions > 27 (even with a fixed CMakeLists.txt as i believe it's related to the Qt5->Qt6 update), if you require this plugin i recommend installing the non rc/git version of obs-studio

I am having trouble building this, getting an error with CMake not able to find LibObs:

CMake Error at CMakeLists.txt:20 (find_package):
  By not providing "FindLibObs.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "LibObs", but
  CMake did not find one.

  Could not find a package configuration file provided by "LibObs" with any
  of the following names:

    LibObsConfig.cmake
    libobs-config.cmake

  Add the installation prefix of "LibObs" to CMAKE_PREFIX_PATH or set
  "LibObs_DIR" to a directory containing one of the above files.  If "LibObs"
  provides a separate development package or SDK, be sure it has been
  installed.

I am using obs-studio-rc currently if that matters.

@araruna, this is an issue with ndi-sdk. if you want to build this package successfully until the PKGBUILD is updated by the maintainer, ensure you have pacman-contrib installed, clone https://aur.archlinux.org/ndi-sdk.git then run updpkgsums && makepkg -cfirs then you can build this package without any issues.

I get the following error (which is in Brazilian Portuguese), which in a nutshell says that the sha256 digest is invalid.

==> Criando o pacote: ndi-sdk 4.5.20200512.r114585-1 (qua 10 jun 2020 23:13:26) ==> Obtendo fontes... -> Encontrado InstallNDISDK_v4.5.20200512.r114585_Linux.tar.gz ==> Validando source arquivos com sha256sums...

@Shaybox, no where in the package is obs-studio built, it is merely pulled in order to source "obs-frontend-api.h" which is required to build the obs-ndi plugin.
