Introduction

The LEADTOOLS Multimedia SDK is designed to provide developers with the full range of tools required to create professional, high-quality multimedia applications. Use it to add multimedia capture, play, and convert functionality, as well as the latest DirectShow filters and multimedia file support to your applications. You can load/convert to and from many common file formats, including WAV, AVI, WMA, WMV, MPEG-1, MPEG-2, OGG, FLV, WebM, MKV, and others. All in all, nearly 100 formats, media types, and subtypes are supported, with full control over compression quality.

LEADTOOLS Multimedia C API

The LEADTOOLS Multimedia C API toolkit is flexible. It gives you full control over the input, middle, and output samples:

Input data can come from the following sources:

Data can be output to:

Input streams can be very different (MPEG-2 Transport over UDP, TCP/IP, RTSP server feeding RTP packets, HTTP stream, etc.) However, as far as your application is concerned, all you have to do is set the stream's URL as the source and the toolkit handles the rest. The output is handled in the same way: set the output to a URL and the toolkit will take care of streaming the data.

The LEADTOOLS Multimedia API provides dynamic link library (DLL) functions that can perform the following tasks:

Capture graphs can be very complex when using DirectShow directly. LEADTOOLS abstracts the process, eliminating the complexity and allowing the developer to treat all capture devices in a uniform manner.

For more information, see the Feature Diagrams, below.

DirectShow Filters

The LEADTOOLS Multimedia SDK includes full or evaluation versions * of all DirectShow Filters. Filters encompass encoders, decoders, multiplexers, demultiplexers, sources, and sinks.

The evaluation download also includes evaluation versions * of the DVD writer, DVD burner, MPEG-1 multiplexer, MPEG-2 multiplexer, ISO multiplexer/demultiplexer, Screen Capture filter, Network filters (source, mux, sink, and protocol manager) (TCP/IP, UDP, RTSP), DICOM medical toolkit filters, and more.

Refer to LEADTOOLS DirectShow Filters for a complete listing of available DirectShow filters. Refer to the Multimedia Product Comparison Chart to see which licensed filters are included with the various LEADTOOLS products.
