TAPI Audio, Video and RTP Filters

The TAPI Audio, Video and RTP Filters component implements several Microsoft DirectShow filters used to stream audio and video data. This component includes filters for encoding and decoding audio and video, as well as filters for sending or receiving audio and video packets using Real-Time Transport Protocol (RTP) over User Datagram Protocol (UDP). The receiving network filter will also demultiplex the incoming packets. The network filters use the generic quality of service (GQOS) API to provide quality of service (QOS) reservations and CryptoAPI to provide decryption and encryption of the audio and video streams.
