I downloaded that file and poked around and it's a whole lot of .deb files, which
are essentially for debian or ubuntu,. however rather than messing around with those,
there's an overlay called megacoffee that has the blackmagic video here:
https://gpo.zugaina.org/Overlays/megacoffee/media-libs/blackmagic-desktop-video.
I would perhaps go that way? |

Hello, thank you for your reply
Yes, I tried another ebuild and it gave me error, I searched the error on the internet and found the same error on the blackmagic forums, it was related to kernel 6.13. Someone published two patches, I applied them and it compiled perfectly, I can install the binaries from the .deb package manually to my root, run dkms and start modprobe and it worked, what happens is that this last driver is old and it doesn't detect my capture machine, in blackmagig is version 4.15 for mac and windows, but they haven't released yet in linux.
I have to open a post in the blackmagic forums asking why it doesn't detect my card. |

In the link you originally gave (with 14.4) there are many Firmware bin files, perhaps your card requires this firmware? |

elover,
dmesg will tell if you need firmware but it fails to load.
kernel drivers bind to devices by knowing the Vendor and Device ID (mostly).
If you feel lucky, add the Vendor and Device ID to your kernel module and see what happens.
== edit ==
Knowing how your device is connected and its Vendor and Device ID would be good.
I'm not about to download your file from Google. Javascript ... etc. but I might get it from the source, if you post a link.

elover,
Put the patches into /etc/portage/patches/... and emerge your kernel.
Portage will apply the patches for you. just like that to quote Tommy Cooper.
The ebuild goes into your local overlay. That's covered on the Wiki too.
