This help file provides API platform information for the LEADTOOLS Media Streaming software development toolkit (SDK).

LEADTOOLS Media Streaming SDK

The LEADTOOLS Media Streaming SDK is designed to provide developers with a full range of the tools required to quickly and easily create professional, high-quality multimedia streaming applications capable of streaming to any device. With LEADTOOLS, using just a few lines of code, you can add multimedia streaming that simultaneously supports industry standard protocols from single source videos.

The LEADTOOLS Media Streaming SDK is ideal for developers who wish to create servers or web sites for streaming large amounts of multimedia content. The SDK makes it easy to stream the video stored in one format (MP4) to any available device. Source files are stored as MP4 and are automatically converted from MP4 to whatever format is required by the streaming specification for the device on which the video is being viewed (for example, the Apple HTTP Live Streaming specification uses an MPEG2 Transport container, so LEADTOOLS will automatically convert MP4 to MPEG2 Transport on-the-fly).  This allows the content provider to maintain content in only MP4 format and stream to all devices.

The SDK also makes it possible for live streaming from a variety of sources. Streams with compatible H264 data can be streamed without recompression, while others will be recompressed on the fly using H264 video and AAC audio compression.
