Bento4
A full-featured C++ toolkit for reading, writing, and processing MP4 files. Bento4 is often used for packaging content for MPEG-DASH and HLS, including encryption and manifest generation.
Encryption
Haivision SRT
Secure Reliable Transport protocol open source implementation that provides low-latency video streaming over unpredictable networks with error recovery and encryption.
Shaka Packager
A media packaging tool by Google for DASH and HLS. It can take encoded media and produce encrypted or unencrypted segments and manifests. Supports Widevine, PlayReady, and FairPlay DRM packaging (CENC).
Bento4
A C++ library and tools for parsing, modifying, and creating MP4 files. Bento4 includes command-line utilities (mp4encrypt, mp4dash, etc.) for packaging and encrypting media for DASH and HLS.
Common Encryption (CENC) Standard
The ISO/IEC 23001-7 standard for Common Encryption in ISO base media file format files. CENC allows a single video file to be encrypted once and used with multiple DRM systems (Widevine, PlayReady, etc.) by defining a common encryption scheme and signaling, forming the basis of DRM interoperability in DASH and HLS fMP4.

bento4.mp4encrypt
Part of the Bento4 suite, mp4encrypt is a command-line utility to apply DRM encryption (e.g., Common Encryption) to MP4 files. It’s used to encrypt media files for DASH (cenc) or HLS (sample AES) and is essential for preparing content protection in adaptive streaming workflows.
