Multimedia Conversion SDK Libraries

LEADTOOLS Multimedia SDKs provide the necessary tools to convert multimedia formats and streams. With LEADTOOLS, developers can leverage DirectShow and Media Foundation to add audio and video conversion into their .NET (C# & VB) and C/C++ applications to fulfill requirements such as archival, Internet streaming, and mobile compatibility.

Feature-rich Multimedia Conversion SDK

Format to Format Conversion

The LEADTOOLS conversion libraries provide components to convert AV streams with many configurable options and features. Options include conversion pause and resume, frame preview, and logging. Quickly convert from one format to another with or without re-encoding the streams. Large files can be distributed across multiple processors or disparate computers. Any DirectShow or Media Foundation source and target can be used for conversion while applying audio and video filters.

Split and join multimedia streams

Split and Join Files and Streams

The Convert control provides the APIs needed to join multiple files into one file or split one file into multiple. Additionally, the APIs provide functions to join still images into a video file or split video into still images. LEAD's Audio Mixer filter can join multiple audio streams into one with control over the level of each stream.

Libraries to convert DVDs

DVD Conversion

Convert entire discs or specific chapters and titles using the LEADTOOLS DVD Navigator. Whether you need to rip from a DVD, create DVD images, or burn DVDs, the LEADTOOLS DVD API gives you everything you need.

Libraries that support Distributed Transcoding

Distributed Transcoding

The LTES filter optimizes multimedia file conversion by splitting each stream into pieces for parallel conversion. Parallel conversion can be performed on a single computer using multiple threads or distributed across multiple computers. Developers can create enterprise audio/video processing and transcoding applications that provide faster file conversions and reduced client CPU usage.

Metadata multimedia libraries


Beyond converting video and audio streams, the LEADTOOLS libraries can convert closed captioning information to readable formats such as SubRip (SRT) and text as well as add KLV metadata to MPEG-2 Transport streams
