How to Install MPlayer and MEncoder on Fedora

· Eric Ma · updated April 12, 2026

MPlayer and MEncoder are no longer actively maintained, but they’re still available through RPM Fusion if you need them for legacy content or specific workflows. Most users should consider modern alternatives like mpv (MPlayer’s successor) or ffmpeg for transcoding, but this guide covers the traditional setup.

Enable RPM Fusion Repository

RPM Fusion hosts packages Fedora doesn’t include in its official repositories. Add both free and nonfree repos:

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

Install MPlayer and MEncoder

Once RPM Fusion is enabled:

sudo dnf install mplayer mencoder

Verify the installation:

mplayer --version
mencoder -version

Codec Support

Modern Fedora includes most codecs through FFmpeg dependencies, so manual codec installation is rarely necessary. If you encounter unsupported formats, first try upgrading your codec libraries:

sudo dnf install ffmpeg

Playing RMVB and Legacy Formats

RMVB files may require additional libraries. Install compatible C++ runtime libraries:

sudo dnf install libstdc++ libstdc++-devel

Test playback with verbose output to diagnose issues:

mplayer -v file.rmvb

Common MPlayer Usage

Play a file with subtitles:

mplayer -sub subtitle.srt video.mkv

Seek to a specific time (in seconds):

mplayer -ss 120 video.mp4

Loop playback:

mplayer -loop 0 file.mp3

MEncoder for Transcoding

MEncoder is useful for batch conversions, though ffmpeg is generally preferred for new scripts. Convert AVI to MP4:

mencoder input.avi -o output.mp4 -ovc lavc -lavcopts vcodec=mpeg4 -oac lavc -lavcopts acodec=aac

Extract audio from video:

mencoder input.mkv -ovc copy -oac copy -of rawaudio -o audio.aac

Resize video during encoding:

mencoder input.avi -o output.avi -vf scale=1280:720 -ovc lavc -oac copy

Modern Alternatives

For new projects, consider these maintained tools:

Install mpv as an alternative:

sudo dnf install mpv

Troubleshooting

If MPlayer crashes or won’t play certain files:

  1. Check available codecs: mplayer -ac help and mplayer -vc help
  2. Try forcing a specific codec: mplayer -ac mad file.mp3
  3. Enable verbose logging: mplayer -v file.mkv 2>&1 | tee debug.log
  4. Consult man mplayer and man mencoder for full option documentation

Troubleshooting Common Issues

If you encounter problems during installation, check these common solutions:

Verification Steps

After installation, verify everything is working correctly by checking the installed version and running basic functionality tests. Most command-line tools respond to the –version or -v flag to display their version information.

Keeping Your Installation Updated

Regularly update your system to receive security patches and bug fixes. On Fedora, use dnf update. On Ubuntu and Debian, use apt update followed by apt upgrade. For software installed via language-specific package managers like pip, npm, or gem, check their respective update commands.

Quick Reference

This article covered the essential concepts and commands for the topic. For more information, consult the official documentation or manual pages. The key takeaway is to understand the fundamentals before applying advanced configurations.

Practice in a test environment before making changes on production systems. Keep notes of what works and what does not for future reference.
