I finally had time to investigate the issue. It looks like that as of 11.5, the DesktopVideoHelper.service has to be running for the capture card to work properly.

fthiery, that worked like a charm.. question is; where is the maintainer..

@Maintainer, compilation works if updated to the 10.8, here is a working PKGFILE # Maintainer: Perry Hung <perry@leaflabs.com> pkgname=decklink _dvver=10.8a2 # DesktopVideo _mever=3.5.2a2 # MediaExpress pkgver=${_dvver} pkgrel=1 pkgdesc="Drivers for Blackmagic Design DeckLink, Intensity or Multibridge video editing cards" arch=('i686' 'x86_64') url="http://www.blackmagic-design.com/products/" license=('custom') makedepends=('curl') depends=('linux-headers' 'libxml2' 'libpng12' 'glu' 'qt4') options=('!strip' 'staticlibs') install='decklink.install' [ "$CARCH" = "i686" ] && _arch='i386' [ "$CARCH" = "x86_64" ] && _arch='x86_64' pkgsrc_url="https://www.blackmagicdesign.com/api/register/en/download/73a8a96378d2459182251738aa516d63" pkgsrc_file=$pkgname-${_dvver}.tar.gz pkgsrc_sha256sum="09d3593b2fd499bdeb794e1cea3972c0dcd997d08eedbe959ea5965d18983268" prepare() { temp_url=`curl --data '{country":"us","platform":"Linux"}' $pkgsrc_url` curl -o $pkgsrc_file $temp_url shasum=`sha256sum $pkgsrc_file | cut -d " " -f1` [ "${shasum}" != "${pkgsrc_sha256sum}" ] && ( echo "Integrity check failed."; exit 1 ) tar xf ${pkgsrc_file} } package() { mkdir -p "$pkgdir/usr/share/licenses/$pkgname" ln -s /usr/share/doc/desktopvideo/License.txt "$pkgdir/usr/share/licenses/$pkgname/COPYING" cd "$srcdir/Blackmagic_Desktop_Video_Linux_${pkgver%a*}/other/${_arch}" tar xf "desktopvideo-${_dvver}-${_arch}.tar.gz" cp -a "desktopvideo-${_dvver}-${_arch}/"* "$pkgdir" mv "$pkgdir/usr/sbin/"* "$pkgdir/usr/bin" rm -rf "$pkgdir/usr/sbin" tar xf "mediaexpress-${_mever}-${_arch}.tar.gz" cp -a "mediaexpress-${_mever}-${_arch}/"* "$pkgdir" }

It appears I was able to install using linux kernel 4.4-lts. During the install it complained about linux Kernel 4.7 Here is some additional information. ==> Continue installing decklink ?

yea, im curious whats the status as im getting similar errors

The software was updated on August 1st. Has the issue been solved?

@rstoye This is a problem with the decklink driver itself, and can only be fixed by blackmagic. I've already contacted the blackmagic development departement, so that they look into it.

doesn't compile with linux-4.6.2-1-x86_64.pkg.tar.xz had to downgrade to linux-4.5.4-1-x86_64.pkg.tar.xz errors encountered: pacman -U decklink-10.6.7a1-1-x86_64.pkg.tar.xz ... /usr/src/blackmagic-10.6.7a1/blackmagic_lib.c/usr/src/blackmagic-10.6.7a1/blackmagic_lib.c:674:8: Fehler: zu viele Argumente für Funktion »get_user_pages« ret = get_user_pages(current_task, ... /usr/src/blackmagic-10.6.7a1/blackmagic_lib.c:704:3: Fehler: Implizite Deklaration der Funktion »page_cache_release« both are related to kernel changes: get_user_pages gets 6 Parameters now (the first two are defaults now, so maybe it should be changed to: ret = get_user_pages((unsigned long)ptr & PAGE_MASK, *nr_pages, write, 0, pages, NULL); 2nd problem: /usr/src/blackmagic-10.6.7a1/blackmagic_lib.c:704:3: Fehler: Implizite Deklaration der Funktion »page_cache_release« thats because page_cache_release was renamed to put_page sadly i am a newbie regarding ARCH, so maybe someone else can fix it?...
