Written by Michael Larabel in Multimedia on 24 September 2025 at 06:28 AM EDT. 19 Comments
The widely-used FFmpeg open-source multimedia library has merged support for MPEG-H 3D Audio decoding.

MPEG-H 3D Audio is the standard for providing immersive next-generation audio and alternative to Dolby Atmos. MPEG-H 3D Audio supports the notion of audio objects, audio channels,and higher order ambisonics and supports up to 128 codec core channels and 64 loudspeaker channels. Those unfamiliar with MPEG-H audio can learn more via mpegh.com.

The news today is that FFmpeg has merged MPEG-H 3D Audio decoding support into this library. The FFmpeg decoding for MPEG-H is relying on the reference Fraunhofer IIS MPEG-H 3D Audio mpeghdec decoder library. This FFmpeg addition was contributed by Daniel Stadelmann of Fraunhofer.

This commit outlines all the details around the new mpeghdec-based MPEG-H 3D Audio decoding support for FFmpeg when built with the new "--enable-libmpeghdec" option.
