Arch Linux User Repository

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.

@Houtworm are you using the lts kernel or the latest one ?

Thanks fthiery, It works perfectly now. Capturing with my Blackmagic Intensity Pro 4K on Arch :)

I replaced the broken download method by a static path (redefine pkgsrc_file after download, by default /tmp/Blackmagic_Desktop_Video_Linux_10.9.tar). Tried to fake the POST request to https://www.blackmagicdesign.com/api/register/us/download/46d65f46d6434b16bd69482b0ca7dba3 (supposed to return the actual download url) but it always ends up with a 504 GATEWAY_TIMEOUT error. curl 'https://www.blackmagicdesign.com/api/register/us/download/46d65f46d6434b16bd69482b0ca7dba3' -H 'Host: www.blackmagicdesign.com' -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0' -H 'Accept: application/json, text/plain, */*' -H 'Accept-Language: en-US,en;q=0.5' --compressed -H 'Content-Type: application/json;charset=utf-8' -H 'Referer: https://www.blackmagicdesign.com/support/download/9d53d0685c754e728c46d6dd57841fc0/Linux' -H 'Content-Length: 35' -H 'DNT: 1' -H 'Connection: keep-alive' --data '{country":"us","platform":"Linux"}' -v The request is supposed to return a url like: http://sw.blackmagicdesign.com/DesktopVideo/v10.9/Blackmagic_Desktop_Video_Linux_10.9.tar.gz?Key-Pair-Id=APKAJTKA3ZJMJRQITVEA&Signature=Mc1SBHRRZ59Uklpc7fiUFwiD5z/gAc5QwTeR7rcROCvGvsWUFmaOTretk8XrMBdVCTbCiG7mFQAk2R+kObuDq2E6Rr305AykYFMtvRxsrRo4yXy2qovgeqXBIOrFeYI/DpmQ4BI450+8Y00MhOlV7d0uyKARqpCy+quWUOtnieWn7kSpUh5JElzCHen9/cMYzKpWi8VIFoGxhhgtMtNd25gwUoNk9O5ROGPw67Z1rIR/SUVrwm4PtQeghM/N89SrM6Nf33D0Q82X0UGINIa2GXrMFGQ5gRFjreDRLIXV0zR2tXAtiZ6HwzL9xIBUrwNvXGtXfdudAZ83uhOwlYPlcg==&Expires=1494342304 If anyone succeeds in programmatically getting this url i'll happily integrate it instead.

Indeed, apparently bmd has improved the download protection, working on it

Sadly it does not build, Failed to download. It gives an error unable to resolve host: invalid request to download. Also manually downloading the file and putting it in the makepkg folder does not work. It would be a nice add to the PKGBUILD to search for local files so that the curl download is not necessary whenever blackmagic desides to change urls. Thanks And Greets

I know, said it below: you need linux-lts to have the driver working, not the latest linux package.

I confirm that it finally works ! gst-launch-1.0 decklinkvideosrc device-number=1 connection=1 mode=16 ! xvimagesink

After a reboot, the device firmware updater reports the device to be up to date.

So it still fails on the current linux, but does compile on linux-lts (4.9.22-1-lts). So you need the linux-lts and linux-lts-headers packages. Device flashing did reportedly fail however, even if the dmesg doesn't report failure [ 89.800430] blackmagic: loading out-of-tree module taints kernel.
