VisioForge Media Player SDK allows programmers to easily integrate video, audio and DVD playback into their software applications. It also allows you to draw overlay bitmap and text over the video with effects.

VisioForge Video Capture SDK allows programmers to easily integrate video capturing and processing capabilities into their software applications. VisioForge Video Capture SDK can play and capture video and audio streams from TV tuners, USB capture devices, DV camcorders, PCI capture cards and IP cameras.

Voice Communicator (VC) components were designed to simplify the development process of VoIP audio streaming applications, such as peer-to-peer voice chat or audio conference. VC components provide real-time low latency multi-client audio streaming over TCP/IP networks and include efficient components for sound recording, playback, encoding, decoding, mixing and resampling as well. Compatible with RTP (RFC 3550) the Transmitter, Receiver and Duplex streaming components make it easy to create peer-to-peer, multi-client, broadcast, multicast and conference-like audio communications applications in no time.

The Datastead RTSP/RTMP/DirectShow Source Filter SDK can capture RTSP, RTMP, UDP, TCP, MMS, HTTP streams, render the uncompressed audio and video streams, and can simultaneously save the native streams to MP4, MKV, AVI, FLV or MOV file without video transcoding.
