GPAC is an open-source multimedia framework for processing, inspecting, packaging, streaming, and playing audio, video, subtitles, encrypted media, and 2D/3D graphics. It is best known for its MP4/ISOBMFF tooling (MP4Box) and MPEG-DASH/HLS packaging capabilities used by broadcasters and streaming services.

Use cases

• package mp4 files for mpeg-dash streaming
• generate hls segments and manifests from video files
• inspect and remux mp4 or mov containers
• encrypt video with cenc for drm delivery
• convert prores or mpeg-ts files to fmp4/cmaf
• build low-latency hls live streaming pipelines
• mux subtitles like webvtt and ttml into mp4
• transcode and package media for broadcast delivery

When to choose

• you need standards-compliant ISOBMFF/MP4 packaging or DASH/HLS segmentation
• you work in broadcast, streaming, or media research and need CENC encryption or ATSC 3.0 support
• you want a scriptable CLI alternative to FFmpeg focused on packaging and streaming

When to avoid

• you only need simple video encoding/transcoding without packaging - FFmpeg may be simpler
• you need a polished end-user media player GUI
• you need lightweight library integration without a large framework dependency
