The GPG key used to sign the packages have been replaced. I originally wanted to do that just after the EOL of EL7, but I obviously forgot to do that.

Plex desktop and HTPC client
Plex Desktop and HTPC clients are available again. Now Plex ships a precompiled QT 6 libraries with the private API enabled that allows for an easy packaging. The packages are available for EL9+ and Fedora on the x86_64 architecture only.
Just install the one you need via DNF. For the desktop application:
# dnf -y install PlexDesktop
For the HTPC application:
# dnf -y install plexHTPC
The packages come with every possible system library in use and can be installed in parallel. They both suggest all the VA-API drivers available in the multimedia repository.
Keep in mind that both sport MPV as the main player, so you can still customize the player options as you see fit. For example to force NVIDIA’s hardware decoding in both applications:
$ cat .local/share/plex/mpv.conf
hwdec=nvdec
The HTPC optional package that creates an auto starting “HTPC session” for set top box media players is not restored yet, I will add it in the next days.
The packages bundle QT 6 (for the web interface engine) with the private API enabled, FFMPeg with a progress API status reporting, a custom MPV and a CEC library in the HTPC client.
Why not using the official Flatpak installation directly? First of all I don’t like all the mounting and folder redirection of Flatpak, but also:
# flatpak install tv.plex.PlexDesktop tv.plex.PlexHTPC
Looking for matches…

That’s more than 7 times the size. Flatpak applications with duplicate libraries everywhere are not really my taste.
CUDA with unsupported GCC versions
When running the CUDA stack on a recent Fedora distribution, you’re very likely to hit the compatibility issue with the current GCC release not being yet supported by NVCC. This is quite easy to address, but not many people seem to know it.
At the moment of writing, CUDA 12.4 has GCC 13.x support, while Fedora 40 ships with GCC 14.
Since a few years I’ve been shipping a cuda-gcc package which appears as a drop in replacement for NVCC. It can be installed along with CUDA and the drivers from the Nvidia or multimedia repository or from a Fedora COPR if you are running the upstream CUDA packages provided by Nvidia.
This GCC version is hidden from the main path and is explicitly used by NVCC when compiling something. Installing the cuda-gcc-c++ package creates profile entries in /etc/profile.d that just do this:
# dnf -y install cuda-gcc-c++
$ cat /etc/profile.d/cuda-gcc.sh
export NVCC_PREPEND_FLAGS='-ccbin /usr/bin/cuda'Logout/login or reload your profile and you’re good to go.
This way, every time you invoke NVCC you are not using the system compiler but the one provided by the cuda-gcc package.
On a Red Hat Enterprise Linux based distribution you can achieve the same result by installting the development toolset of your choice and activating the environment for it. This is usually not an issue as NVCC is officially supported on those distributions.
Nvidia proprietary and open source kernel modules
With the latest bunch of updates to the Nvidia and Multimedia repositories, I’ve added the ability to switch to the two implementations of the kernel modules currently available in the Nvidia driver for Linux.
Since almost a year, the Nvidia driver ships with two different implementations of the kernel modules, one proprietary and one open source. The open source one as of drivers 545.x is now considered beta quality also for the workstations, so it seems a good moment to start shipping it.
The open source one is supposed to be the only one that will be kept in the future, but at the moment both are available and both differ in terms of functionality. You can read about the main differences in terms of functionality and what chips they support in the official documentation.
I did not want to introduce another variation of the kernel modules beside akmods, kABI and DKMS, this would have created even more confusion and lots of dependencies in the SPEC files for the variations. The new akmod and DKMS packages ship both sources (MIT/GPL and proprietary kernel modules) and allow you to switch between one or the other through a configuration file.
Considering that in the long run only the open source variant will remain, I wanted to make this as transparent as possible for the users. Basically, if you don’t care and just want something that works, nothing has changed for you.
The two sources get referenced as they are referenced inside the Nvidia run file, namely “kernel” for the original proprietary kernel modules and “kernel-open” for the new open source variation.
The following instructions show you how to switch between one implementation or the other.
DKMS
Check which version you have installed:
# modinfo -l nvidia
NVIDIAChange the type of modules you want to use and trigger a rebuild and a reinstall:
# sed -i -e 's/kernel$/kernel-open/g' /etc/nvidia/kernel.conf
# dkms build -m nvidia/545.29.02 --force
# dkms install -m nvidia/545.29.02 --forceNow check again the license and you should see that it has changed to MIT/GPL:
# modinfo -l nvidia
Dual MIT/GPL
# rebootTo switch back, change the configuration again and then trigger the same process for rebuilding installing:
# sed -i -e 's/kernel-open$/kernel/g' /etc/nvidia/kernel.conf
# dkms build -m nvidia/545.29.02 --force
# dkms install -m nvidia/545.29.02 --force
# rebootakmods
Check which version you have installed:
# modinfo -l nvidia
NVIDIAChange the type of modules you want to use and trigger a rebuild and a reinstall:
# sed -i -e 's/kernel$/kernel-open/g' /etc/nvidia/kernel.conf
# akmods --rebuildNow check again the license and you should see that it has changed to MIT/GPL:
# modinfo -l nvidia

# sed -i -e 's/kernel-open$/kernel/g' /etc/nvidia/kernel.conf
# akmods --rebuild
# rebootCUDA 9.0, cuDNN 7.0 and Wayland support in Fedora 27
The Nvidia repository now contains packages for Fedora 27. This is with the release candidate of CUDA 9, and it contains also cuDNN at version 7.0, which is the only version supported with CUDA 9 at the moment of writing.
The updated cuDNN 7.0 library has been added also to the other branches, this means it will be automatically upgraded from version 6.0 to 7.0. If you still need one of the previous versions, just remove it and install one of the compatibility packages:
# dnf list cuda-cudnn*
Installed Packages
cuda-cudnn.x86_64 1:7-1.fc26 @fedora-nvidia
Available Packages
cuda-cudnn-devel.x86_64 1:7-1.fc26 fedora-nvidia
cuda-cudnn5.1.x86_64 1:5.1-2.fc26 fedora-nvidia
cuda-cudnn5.1-devel.x86_64 1:5.1-2.fc26 fedora-nvidia
cuda-cudnn6.0.x86_64 1:6.0-1.fc26 fedora-nvidia
cuda-cudnn6.0-devel.x86_64 1:6.0-1.fc26 fedora-nvidia
CUDA 9 supports GCC 6.x and CLANG 3.9, so when it will be officially released, it will cover Fedora 25 and RHEL/CentOS compilers. With Fedora 27, there will be the usual need for a GCC compatibility package (like the compat-gcc53 package currently in the repository) as GCC is at version 7 and CLANG is at version 4.0.
I will try to provide a compat-gcc64 for Fedora 27+ at the time of the official CUDA 9 release.
Regarding the drivers, on Fedora 27 where Mutter 3.25+ is available, the modesetting part of the Nvidia drivers has been enabled by default, this means that at the login you can just select “GNOME” to run Gnome on Wayland. Please note that X 3D programs running on XWayland might not work properly.
CentOS 7.4 package rebases
As many have requested, I’ve enabled the updates for CentOS 7.4. As of this very moment, you need to enable the Continuous Release repository, which will get emptied when the final CentOS 7.4 images will be released. This means all the temporary packages I’ve put in the Red Hat Enterprise Linux 7.4 repository are now mainline.
If you are on CentOS 7.3 please proceed as follows:
# yum clean all
# yum-config-manager --enable cr
# yum update
You can then disable the cr repository (if you want) once CentOS 7.4 is out.
If you are on RHEL 7.4, you need to remove the temporary repository:
# yum clean all
# rm -f /etc/yum.repos.d/rhel74-temp.repo
# yum update
All Gstreamer packages are now at 1.10 as well as some other updates that have been already pushed into the Fedora repositories, like x265, HandBrake, etc..
RHEL 7.4 multimedia packages and Skype repository removal
The upgrade path from Red Hat Enterprise Linux 7.3 to 7.4 is a bit of a pain if you have the multimedia repository configured. This is because I’m rebuilding a few components for an upgraded libwebp package and because a lot of stuff has been rebased to versions that are in Fedora. Judging by the logs, I see that most of the downloads come from CentOS systems, so I just decided to hold on some updates that are required for the various package rebases for Red Hat Enterprise Linux 7.4. So until also CentOS releases version 7.4, I can’t make everyone happy and something (like Gstreamer plugin updates) will be stuck with 7.3 versions. Hopefully the new CentOS release will come quickly enough.
Also, I decided to stop rebuilding the base packages to use a newer libwebp version. This really had very few benefits and just a lot of pain due to the huge amount of packages involved in both x86_64 and i686 variants. The amount of packages affected by this weigh at around 3 gb.
In RHEL 7.4 there are additional WebKit variants that also would require a rebuild. So, as of today, to update the packages from the EPEL 7 multimedia repository you should run this command:
rpm -e --nodeps GraphicsMagick && yum distro-sync && yum -y install GraphicsMagick
Hopefully you would get an output similar to this:

Is this ok [y/d/N]:
Basically libwebp should come again from the main CentOS/RHEL channels and the libwebp0.6 package should come from the multimedia repository. All the packages which were rebuilt for the previous libwebp 0.5 update should become synced again to their proper versions.
If you don’t get this output, but still get some dependency errors you have to do some debugging. For example, ffmpeg-libs.i686 requires libssh.i686, but the version of libssh in CentOS extras is different from the one in EPEL (it really depends on what kind of packages you have installed and with which repositories enabled) so I’m providing here the same version that is in CentOS extras but in both variants.

If you get many qt5 errors during the transactions, keep in mind that RHEL 7.4 has been rebased massively, and everyone else (including EPEL) is catching up. As of today, if you have the following errors (trimmed down) in a Yum transaction:

are some of the packages that are rebased in RHEL 7.4. I’ve created a temporary repository for those, it will disappear once CentOS 7.4 is released as the packages will be integrated in the main multimedia repository. You can install it through:
yum-config-manager \
--add-repo=https://negativo17.org/repos/rhel74-temp/rhel74-temp.repo
With the above repository it is possible to install all the other multimedia packages.
Skype repository removal
Skype 4.3 is 32 bit only, is now obsolete and has been superseded by a package that actually lists proper dependencies. It is also one of the packages that required one of the above WebKit rebuilds in i686 form for RHEL/CentOS 7 x86_64.
If you have it installed, just remove it with:
yum remove webkitgtk.i686
The repository has been deleted; to install the new Skype provided version, just head to the following official link.
Big multimedia repository update (CUDA enablements, rebases, new software)
Merging of the Nvidia repository into Multimedia
The whole multimedia repository has been rebased with recent releases, and it now features FFmpeg 3.2 as the foundation. Most of the programs that suppport some Nvidia integration are now enabled and compiled with support for CUDA/NVENC/CUVID; leveraging the previous reorganization of CUDA 8 in the various subpackages.
This means that all the Nvidia packages are now included in the repository as well, so if you have an Nvidia card and you are interested in both repositories, you can just have the multimedia repository enabled. If you still just want the Nvidia stuff (as enabled in Fedora 25) then it’s still available as a separate repository; and that will not change.
Why all of this? Because I can’t keep them separated anymore. The Nvidia repository can exist on its own, but the multimedia one can’t, due to the dependencies and the constant rebases (also of main Fedora and CentOS/RHEL packages). You can use the Nvidia repository alone, if you just need that, or use the multimedia one if you need everything else.
The repository is now exposed also at this URL, and contains Delta RPM support:
https://negativo17.org/repos/multimedia
All repository files and configurations have been updated, so this means that in the future this would be the place where the metadata and repository information will be placed and any new installation will get the repository from there. If you are reading this blog post, you can switch now. I will add a negativo17-release package soon, along with a few mirrors; I’m sorting out the details now with the mirror owners.
FFmpeg and other CUDA enablements
To make proper use of the Nvidia hardware encode features (NVENC/CUVID) and CUDA kernel support (i.e. Blender GPU rendering) in the various programs you need the Nvidia driver installed (nvidia-driver-cuda), and for Nvidia Performance Primitives you require the CUDA driver and the NPP library package (cuda-npp).
This means that for most people NOT requiring CUDA support or not using an Nvidia video card, the following 2 packages will be installed anyway:
$ ls -alghs nvidia-driver-cuda-libs*.rpm cuda-npp*.rpm
92M -rw-r--r-T. 1 mock 92M Nov 16 12:35 cuda-npp-8.0.44-6.fc25.x86_64.rpm
22M -rw-r--r-T. 1 mock 22M Nov 19 15:00 nvidia-driver-cuda-libs-375.20-1.fc25.x86_64.rpm
Both packages contain just libraries, and they will be on your system as much as other libraries for multimedia codecs you don’t actually need. Example, with most multimedia programs you will get Xvid libraries for opening Xvid files, even though the format is pretty much abandoned. Having them installed does not enable any unwanted feature in your system. Also, NPP libraries should decrease 50% in size in one of the next CUDA updates, being the monolithic version of the library being deprecated in favor of split functionality.
There are some patches being evaluated to make those libraries loadable at runtime, but they have not been merged yet and there’s no guarantee that they ever will. Also, they are available for FFmpeg but not for all the other programs where support has been enabled for; so depending on your installation, you might get them anyway.
As of today, from the Multimedia repository the following programs have been enabled with some Nvidia hardware enablement:
- MPV (video decoding through CUVID)
- FFmpeg (encoding through NVENC, decoding through CUVID and filtering through CUDA NPP)
- Avidemux (encoding, through NVENC)
- GStreamer (NVENC plugin)
- Blender (GPU rendering)
VDPAU for decoding was already enabled where possible.
Of course anything that is using FFmpeg (like the GStreamer plugins) could theoretically benefit from the same enablements as in FFMpeg:
$ for i in encoders decoders filters; do
echo $i:; ffmpeg -hide_banner -${i} | egrep -i "npp|cuvid|nvenc|cuda"
done

filters:

I think this will be much appreciated for you users out there that are already using CUDA for deep learning and FFMpeg to process data 🙂
Rebases: FFmpeg, HandBrake, VLC, OpenH264, WebP (CentOS/RHEL), MPV.
A note on Blender: Blender with CUDA support is still at 2.78 built with CUDA 7.5, and not 2.78a built with CUDA 8; so no Nvidia Pascal GPU support. I’m working on it.
GNOME Software integration
Most of the graphical software is now enabled in GNOME software for Fedora 25, meaning that you can search stuff with a keyword and that if you have the repository enabled it will just pop-up:
There is still some packages that need AppStream metadata, but that will come.
As usual, feedback, bugs and comments are welcome.
CUDA 8, cuDNN, Nvidia drivers and GNOME Software metadata
GNOME software integration
The Nvidia driver repository has been updated with AppStream metadata. From Fedora 25 onward, you will be able to search for Nvidia, CUDA, GeForce or Quadro to make the driver, control panel and other programs appear in the Gnome Software window.
As far as I know, this should be enabled by default on Fedora 25.
Thanks to Richard Hughes for helping out with the metadata.
I require proper 16:10 aspect ratio pictures for both NSight and the Visual Profiler running on Fedora, so if you want to contribute just drop me an email or open an issue on the CUDA package on GitHub.
Changes to the Nvidia driver packaging
The Nvidia driver can now be installed without nvidia-settings (the control panel utility) as requested by Red Hat, in preparation for the Gnome software integration. This means the dependencies have been reversed, and that to install the driver and the control panel you need to install nvidia-settings or the driver and nvidia-settings:
dnf/yum -y install nvidia-settings kernel-devel
The libglvnd package has been updated to the latest snapshot and now features all the changes that have been introduced by Adam Jackson for the Mesa GLVND integration in Fedora 25. This means that while installing you will be prompted to install/upgrade smaller packages that contain a subset of the libglvnd libraries, this includes EGL support for the recently released beta drivers version 375.10. For anything lower than 375.10 (so Fedora 23-24 and CentOS/RHEL 6/7 at the moment of writing this) Nvidia’s last official note on EGL is:
“libEGL.so.1, while not a proper GLVND library, depends upon the GLVND infrastructure for proper functionality. Therefore, any driver package which aims to support NVIDIA EGL must provide the GLVND libraries […]”
So for now, in Fedora 23, 24 and CentOS/RHEL 6/7:
$ rpm -q --requires nvidia-driver-libs.x86_64 | grep libglvnd
libglvnd-gles(x86-64) >= 0.1.1
libglvnd-glx(x86-64) >= 0.1.1
libglvnd-opengl(x86-64) >= 0.1.1
$ rpm -q --conflicts nvidia-driver-libs.x86_64 | grep libglvnd
libglvnd-egl(x86-64) >= 0.1.1
And for Fedora 25:
$ rpm -q --requires nvidia-driver-libs.x86_64 | grep libglvnd
libglvnd-egl(x86-64) >= 0.2
libglvnd-gles(x86-64) >= 0.2
libglvnd-glx(x86-64) >= 0.2
libglvnd-opengl(x86-64) >= 0.2
Not a big deal. This accommodates the ongoing modularization in Mesa but still preserves the original EGL libraries from Nvidia. The upgrade should be transparent and you should not notice any difference except some smaller packages being installed.
Vulkan is now part of Fedora, so on supported Fedora releases, the Vulkan loader and libraries can be installed and you do not need to do anything to enable support in the drivers. CentOS and Red Hat Enterprise Linux do not have Vulkan yet. I’m not sure if it’s worth installing it by default along with the drivers, though.
Let’s assume you have a freshly installed Fedora 25 system with a recent Nvidia GPU and you want to:
- Install the driver for gaming
- Play Vulkan enabled games
- Want to be comfortable with the control panel
- Play 32 bit games on a 64 bit system
- Play 32 bit Vulkan games on a 64 bit system
$ sudo dnf install nvidia-settings kernel-devel dkms-nvidia vulkan.i686 nvidia-driver-libs.i686

Is this ok [y/N]:
Note that the requirement on kernel-devel is still required as otherwise the package kernel-debug-devel is pulled in automatically in place of the normal non-debug package. There is bug opened on dnf/libsolv for this.
Changes to CUDA packaging
The CUDA packages hosted on the Nvidia repository are split into multiple subpackages, based on the library. For each library, you have the corresponding devel subpackage with the headers, the unversioned library symlink and the static library. Here, they were divided in one libs, one big extra-libs, one static and one devel subpackage for everything. Since I’m planning to enable CUDA/NVCUVID encoding/decoding in FFmpeg (I’m actually waiting to the dynamic loader patches to land in the 3.2 branch before enabling that) there should be a way to install just what is required by those functions and not the whole CUDA toolkit set of libraries.
So now, all the libraries are split into subpackages, much like in the original Nvidia CUDA repository. This allows you to install and build software relying on specific components without the need to install all the CUDA toolkit just to satisfy a library dependency. With the new packaging organization, the original cuda-devel and cuda-extra-libs will pull in all the specific subpackages giving you the same situation you are accustomed to. Also, for the same reason, static libraries have been included in each respective devel subpackage.
Example, just with the basic tools:
$ sudo dnf install cuda

The nvidia-driver-NVML-devel package, which was including the NVML header (for libnvidia-ml.so) has now been made obsolete by the new headers, which are now part of CUDA 8. So the cuda-nvml-devel package will take care of that. Again, this is the same as in the Nvidia repository. Everything that was requiring the NVML header now refers to that package instead of the previous one. I will leave it for a few releases like that and then I will remove the Obsolete/Provides tags from the various SPEC files.
The header is also required for building the latest nvidia-settings from the 375.10 source, this has been taken into account making the CUDA package buildable on i686 but generating only the cuda-nvml-devel subpackage.
Extra stuff
In addition to the libraries bundled in the CUDA toolkit, also the cuDNN library for distributed neural networks is included in the repository.
As usual, you are welcome to open bugs / request stuff / comment on the GitHub repositories.
GStreamer plugins for CentOS/RHEL 7, MPV and Fedora 25 repositories
The Multimedia repository now provides GStreamer (1.0) plugins for Bad, Ugly, libAV and VA-API plugin bundles with all options enabled for CentOS/RHEL 7. As per the Fedora ones, these are split into the following GStreamer runtime packages:
gstreamer1-plugins-badgstreamer1-plugins-uglygstreamer1-plugins-vaapigstreamer1-plugins-libavgstreamer1-plugins-bad-fluidsynth(pulls in the whole FluidSynth distribution)
They all have an Epoch of “1”, to avoid any upgrade issue. Like for FFMpeg, I’ve tried to enable all the supported plugins out of the box. The “bad” package actually obsoletes the “bad-free”, “bad-nonfree” and “openh264” Gstreamer plugin packages. As such, they play nicely when enabling OpenH264 support on Firefox.
Apart from this, 99% of the Fedora 25 packages are now available, Fedora 24 and Fedora 25 repositories now have MPV in them.
Next steps
Next steps:
- OpenH264 1.6
- FFMpeg with support for the new OpenH264 and the other Nvidia enablements.
- x265 2.0, libvpx, FFMpeg and libwebp rebases also for CentOS/RHEL 7
- Finishing support for Fedora 25
- MPV support for CentOS/RHEL 7
- New Skype
- New Nvidia drivers with PRIME and PRIME Synchronization
