The issue you’re encountering is due to conflicting versions of ffmpeg and its libraries from the Fedora and RPM Fusion repositories. To resolve this, you can allow dnf to erase the conflicting packages and install the versions from RPM Fusion.

Here’s how to do it:

  1. Enable RPM Fusion Repositories (if not already done):

    sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

  2. Install the Necessary Packages with the --allowerasing Option: This command will allow dnf to replace conflicting packages with the appropriate ones from RPM Fusion:

    sudo dnf install ffmpeg ffmpeg-libs vdpauinfo libva-utils --allowerasing

This should resolve the conflicts by allowing dnf to replace the ffmpeg-free packages with the full ffmpeg versions from RPM Fusion.

Step-by-Step Instructions

  1. Open Terminal: Open your terminal application.

  2. Enable RPM Fusion Repositories: If you haven’t enabled the RPM Fusion repositories yet, run:

    sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

  3. Update Your System: Make sure your system is up to date:

    sudo dnf update

  4. Install the Necessary Packages with Conflict Resolution: Run the following command to install ffmpeg and its libraries, allowing dnf to replace conflicting packages:

    sudo dnf install ffmpeg ffmpeg-libs vdpauinfo libva-utils --allowerasing

  5. Verify Codec Support: After installation, you can verify that the E-AC3 codec is supported by running:

    ffmpeg -codecs | grep eac3

  6. Play E-AC3 Audio with mpv: You should now be able to play E-AC3 5.1 audio files using mpv:

    mpv yourfile.mkv

Following these steps should resolve the conflicts and allow you to install the necessary codecs for playing E-AC3 audio files with mpv on Fedora.

Proprietary Codecs

Yes, it is possible to install proprietary codecs on Fedora Linux to improve video encoding performance and compatibility. Here’s how you can do it:

  1. Enable RPM Fusion Repositories: RPM Fusion provides additional software that the Fedora Project or Red Hat does not ship, including proprietary codecs.

    First, enable the free and nonfree repositories:

    sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

  2. Update Your System: Make sure your system is up to date.

    sudo dnf update

  3. Install Proprietary Codecs: Install the necessary codecs for multimedia support.

    sudo dnf groupupdate multimedia --setop="install_weak_deps=False" --exclude=PackageKit-gstreamer-plugin
sudo dnf groupupdate sound-and-video

  4. Install FFmpeg with Proprietary Codecs: Install FFmpeg and ensure it has support for proprietary codecs.

    sudo dnf install ffmpeg ffmpeg-libs

  5. Install NVIDIA Drivers (if applicable): If you have an NVIDIA GPU, install the proprietary NVIDIA drivers for better performance.

    sudo dnf install akmod-nvidia
sudo dnf install xorg-x11-drv-nvidia-cuda

After completing these steps, you should have support for proprietary codecs on your Fedora system, which will help with video encoding tasks.

To verify that FFmpeg can use these codecs, you can check the available codecs with:

ffmpeg -codecs | grep -i dts

You can now use FFmpeg with the installed proprietary codecs for video encoding.
