![]() The Developers Page contains specific information on where to obtain the source code and documentation. You can find out more about the license on the About Page. The library is Open Source, with a dual-license model. There is also support for building the library with the SCons build system as well as CMake. The standard distribution contains makefiles for unix-like operating systems, including Linux and Android, project files for Microsoft Visual Studio, and an XCode project for MacOS X and iOS. All the code necessary to compile the SDK and tools is included in the standard distribution. The implementation does not rely on any external library. The code is very portable it can be compiled with any sufficiently modern C++ compiler. The SDK is designed to be cross-platform. Support for a wide range of codecs, including H.264 (AVC), H.265 (HEVC), AAC, HE-AAC, xHE-AAC, AC3 and eAC3 (Dolby Digital), AC4, Dolby Atmos, DTS, ALAC, and many more.Support for multiple DRM systems that are compatible with MP4-formatted content (usually leveraging CENC Common Encryption), such as Marlin, PlayReady, Widevine, FairPlay and Adobe Access.Parsing and multiplexing of H.264 (AVC) video and AAC audio elementary streams.The UltraViolet (DECE) CFF (Common File Format).ISO-MP4 files profiled as part of the 3GPP family of standards.OMA 2.0 and 2.1 DCF/PDCF Encryption and Decryption as defined in the OMA specifications.ISMA Encrytion and Decryption as defined in the ISMA E&A specification.Reading and writing 3GPP and iTunes-compatible metadata.PIFF (Protected Interoperable File Format), and encrypted, fragmented MP4 format specified by Microsoft and used for encrypted HTTP Smooth Streaming.MPEG Common Encryption (CENC) as specified in the international specification ISO/IEC 23001-7.CMAF (Common Media Application Format) as defined in ISO/IEC 23000-19. ![]() ![]() ![]() HLS with TS or MP4 segments (dual DASH/HLS output), as defined in RFC 8216.MPEG DASH with fragmented MP4 files, as defined in the international specification ISO/IEC 23009-1.Features ¶Ī number of formats and features based on the ISO-MP4 format and related technologies are also supported, including: In addition to supporting ISO-MP4, Bento4 includes support for parsing and multiplexing H.264 and H.265 elementary streams, converting ISO-MP4 to MPEG2-TS, packaging HLS and MPEG-DASH, CMAF, content encryption, decryption, and much more. The format is a derivative of the Apple Quicktime file format, so Bento4 can be used to read and write most Quicktime files as well. This format is defined in international specifications ISO/IEC 14496-12, 1.
