LibreOffice Impress Supported Video and Audio Codecs
LibreOffice Impress allows users to embed and play multimedia directly within slide presentations. Rather than relying on a standalone internal codec library, Impress natively leverages the underlying operating system’s multimedia framework to decode and render media files. This guide details how audio and video support works across different operating systems, the specific formats supported by each platform, and the best file formats to use for cross-platform compatibility.
How Media Playback Works in LibreOffice
LibreOffice does not bundle custom video or audio decoders. Instead, it delegates media processing to the operating system’s native multimedia subsystem. As a result, the codecs supported by LibreOffice Impress depend directly on what the host system can decode natively or through installed system-level codecs.
Supported Formats by Operating System
- Windows: LibreOffice uses the Windows Media
Foundation (and legacy DirectShow) frameworks.
- Video: MP4 (H.264, MPEG-4, H.265/HEVC with system extension), WMV, and AVI.
- Audio: MP3, WMA, AAC, M4A, and uncompressed WAV.
- macOS: LibreOffice uses Apple’s
AVFoundation framework.
- Video: MP4, M4V, and MOV (encoded with H.264, Apple ProRes, or HEVC).
- Audio: AAC, MP3, M4A, AIFF, and uncompressed WAV.
- Linux: LibreOffice relies on the
GStreamer framework (
gstreamer1.0).- Video: WebM (VP8, VP9), Ogg Theora, and standard
MP4 (H.264), provided appropriate GStreamer plugin packages
(
gstreamer1.0-plugins-good,ugly, orbad) are installed on the system. - Audio: Ogg Vorbis, FLAC, Opus, MP3, and WAV.
- Video: WebM (VP8, VP9), Ogg Theora, and standard
MP4 (H.264), provided appropriate GStreamer plugin packages

Recommended Formats for Cross-Platform Compatibility
If a presentation must be opened on different operating systems (such as creating a presentation on Linux and presenting it on Windows or macOS), use the following standardized formats to avoid playback failures:
- Video: MP4 container with H.264 video and AAC audio. This is the most widely supported combination across modern versions of Windows, macOS, and Linux.
- Audio: MP3 or WAV (PCM). MP3 offers widespread support with smaller file sizes, while WAV offers uncompressed, universal compatibility without requiring third-party codec plugins.
