Bento4 is a C++ class library and set of command-line tools for reading, writing, inspecting, encrypting, and packaging ISO-MP4 files, including MPEG DASH, HLS, and CMAF packaging. It supports a wide range of codecs and DRM encryption schemes such as CENC, PlayReady, Widevine, and Marlin.

Use cases

• package mp4 videos for mpeg dash streaming
• create hls playlists and segments from mp4 files
• inspect mp4 file structure and track details
• encrypt mp4 with cenc for widevine or playready drm
• decrypt cenc-encrypted mp4 files with a key
• extract h264 or aac elementary streams from mp4
• fragment or split mp4 files for adaptive streaming
• edit mp4 metadata and atoms

When to choose

• you need programmatic or CLI-level MP4 parsing, editing, or packaging in C++ or via command line
• you are building a DASH/HLS/CMAF packaging pipeline
• you need CENC encryption/decryption for DRM workflows
• you want a dependency-free, portable C++ media format SDK

When to avoid

• you need to transcode or re-encode video/audio codecs
• you want a GUI media tool
• you need a high-level player or streaming server rather than file-level tooling
