Multimedia Introduction

This help file provides .NET platform information for:

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

The LEADTOOLS toolkit is flexible and gives you full control over the input, middle and output samples:

Input data can come from any of the following sources:

Data can be output to:

The input streams can be very different (MPEG-2 Transport over RTP, UDP or TCP/IP, RTSP server feeding RTP packets, http stream, etc), but as far as your application is concerned, all you have to do is set the stream 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.

Add-on modules are available to enhance these capabilities. The LEADTOOLS DVD Module adds functionality for programmatically creating, capturing, authoring, burning, and playing DVD images. The LEADTOOLS Streaming Module is perfect for developers who need to implement video conferencing or serve videos on demand, using a standard IIS web server or the Microsoft Media Server. The LEADTOOLS MPEG-2 Transport Module can be used to play and process MPEG-2 Transport Streams used by satellites and UAVs (Unmanned Aerial Vehicle). The DVR components of the  LEADTOOLS MPEG-2 Transport Module can be used to create and play DVR files, and adds DVR support to the Capture, Convert and Play objects. The LEADTOOLS Multimedia Suite includes the LEADTOOLS Multimedia toolkit, all of the modules listed above, every LEAD codec and filter (except the DICOM filters), and the LEADTOOLS Cloud SDK.

The LEADTOOLS Multimedia SDK includes full or evaluation versions* of many DirectShow and Media Foundation filters such as encoders, decoders, multiplexers, demultiplexers, sources, and sinks. Also included are 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 and LEADTOOLS Media Foundation Filters for a complete listing of available filters. Refer to the Multimedia Product Comparison Chart to see which licensed filters are included with the various LEADTOOLS products. LEADTOOLS Multimedia includes evaluation versions of all DirectShow and Media Foundation filters for use in development and testing.

[*] Some filters are included with the LEADTOOLS Multimedia SDK, while others are included with one or more of the LEADTOOLS add-on modules. In addition, these filters can be licensed individually on an a la carte basis. For pricing on filter and codec client licenses, contact
