Backporting gtk-gnutella on Debian buster.

 It seems Debian 10 does not have this package in the repository, but Debian unstable has. So we'll try building a deb for Debian buster -- 

aptitude install libdbus-1-dev libglib2.0-dev libgnutls28-dev=3.6.7-4+deb10u6 libgtk2.0-dev libxml2-dev zlib1g-dev fakeroot

apt-get source --compile gtk-gnutella

This'll result in the deb being generated. Install it -- 

dpkg -i gtk-gnutella_1.1.15-1_amd64.deb

Alternatively, you may download the deb directly --

Cleanup -- 

aptitude markauto libdbus-1-dev libglib2.0-dev libgnutls28-dev libgtk2.0-dev libxml2-dev zlib1g-dev fakeroot
apt-get autoremove

Debian buster -- Working VAAPI (hardware video decoding) for newer intel hardware (like ice lake/gen 11 intel GPU (UHD)).

In case you cannot get hardware video acceleration to work on your new Intel processor, apart from trying to install the backported kernel, you may also need a newer intel-media-va-driver (as of the current time 21.1.1 is the latest from testing).

In this article, it'll be shown how to backport these yourself (since no backports are available) from testing. Alternatively, you can find prebuild backports from here --

Extract and install all the debs (dpkg -i *.deb)

To test -- 

LIBVA_DRIVER_PATHS=/usr/lib/x86_64-linux-gnu/dri/ LIBVA_DRIVER_NAME=iHD vainfo

In case you want to build this yourself, take the following instructions -- 

Add the following to /etc/apt/sources.list -- 

deb stable main
deb-src stable main
deb bullseye main contrib non-free
deb-src bullseye main contrib non-free
deb bullseye/updates main contrib non-free
deb-src bullseye/updates main contrib non-free
deb bullseye-updates main contrib non-free
deb-src bullseye-updates main contrib non-free

deb sid main contrib non-free
deb-src sid main contrib non-free

Next install packages --

aptitude install debhelper=13.3.3~bpo10+1 dwz=0.13-5~bpo10+1 libdrm-dev libgl1-mesa-dev libwayland-dev libx11-dev libxext-dev libxfixes-dev pkg-config build-essential libset-scalar-perl

Generate debs to be installed -- 

apt-get source --compile libva=2.10.0-1

Install all the resulting debs -- 

dpkg -i libva-dev_2.10.0-1_amd64.deb libva-drm2_2.10.0-1_amd64.deb libva-glx2_2.10.0-1_amd64.deb libva-wayland2_2.10.0-1_amd64.deb libva-x11-2_2.10.0-1_amd64.deb libva2_2.10.0-1_amd64.deb

Install build-depends of intel-media-driver -- 

aptitude install debhelper=13.3.3~bpo10+1 dh-sequence-libva cmake libigdgmm-dev=20.4.1+ds1-1 libx11-dev pkg-config

Generate the debs -- 

apt-get source --compile intel-media-driver=21.1.1+dfsg1-1

And install the generated debs.

Cleanup -- 

aptitude markauto debhelper dwz libdrm-dev libgl1-mesa-dev libwayland-dev libx11-dev libxext-dev libxfixes-dev pkg-config build-essential libset-scalar-perl libva-dev libva-drm2 libva-glx2 libva-wayland2 libva-x11-2 libva2 dh-sequence-libva cmake libigdgmm-dev libx11-dev pkg-config

apt-get autoremove
