libheif vs Liquidsoap
A side-by-side editorial comparison of libheif and Liquidsoap — release velocity, themes, recent moves, and the top alternatives to consider.
libheif vs Liquidsoap: at a glance
What is libheif?
The HEIF library quietly became a video decoder, then a scientific image container.
libheif is at 1.22.0. Two releases in this window changed what the library is for: 1.21.0 added full read and write support for HEIF image sequences, which also lets it decode most MP4 video, and 1.22.0 opened a public API for arbitrary image components with signed, float and complex pixel types. The releases between them are build fixes and a maintenance patch.
What is Liquidsoap?
Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

The HEIF library quietly became a video decoder, then a scientific image container.
◆ Current state
libheif is at 1.22.0. Two releases in this window changed what the library is for: 1.21.0 added full read and write support for HEIF image sequences, which also lets it decode most MP4 video, and 1.22.0 opened a public API for arbitrary image components with signed, float and complex pixel types. The releases between them are build fixes and a maintenance patch.
◆ Where it's heading
libheif is expanding along two axes at once — time, via sequences and an x264 encoder plugin, and channel semantics, via multi-spectral and filter-array data that has nothing to do with human vision. The ISO/IEC 23001-17 rewrite that picks the codec path from the input is what makes the second axis practical rather than theoretical.
◆ Prediction
The 1.22.0 notes say generic components are currently limited to the 23001-17 codec with JPEG 2000 to follow, so the next release most likely extends that component model to JPEG 2000 rather than opening a third front.

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
◆ Current state
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.
◆ Where it's heading
Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.
◆ Prediction
The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.
