I was trying to install BlackMagic driver on newest Ubuntu 15.10 (64bit) but was stuck with error messages:

Setting up desktopvideo (10.5a17) ... Preparing new blackmagic driver

Possible causes:
1. Driver is incompatible with your kernel version
2. Kernel headers/gcc/make/etc. is not installed
3. Kernel header version does not match the running kernel (4.2.0-16-generic)

Is there some way to install on newer Linux kernel?

Here a short procedure for patching the BlackMagic 10.5 drivers to work on 64-bit Debian systems with 4.2.x kernels:

1. Download and unpack the drivers. (Blackmagic_Desktop_Video_Linux_10.5.tar.gz)
2. sudo apt-get install git if it isn't there already.
3. cd Blackmagic_Desktop_Video_Linux_10.5/deb/amd64
4. Patch the deb using fakeroot and driver code from Github:

 fakeroot sh -c ' mkdir tmp; dpkg-deb -R desktopvideo_10.5a17_amd64.deb tmp; cd tmp/usr/src; git clone rm -rf blackmagic-10.5a17/ && mv blackmagic blackmagic-10.5a17/; git clone rm -rf blackmagic-io-10.5a17/ && mv blackmagic-io blackmagic-io-10.5a17/; cd ../../../; dpkg-deb -b tmp desktopvideo_10.5a17_amd64-patched.deb; '

5. sudo dpkg -i desktopvideo_10.5a17_amd64-patched.deb
6. Continue with the rest of the installation as normal.

Credit @iperry for the driver patch.
