Info

• Supported live media sources include: digital cameras, microphones, TV-tuners, analog video sources connected to video card or to Video capture card that supports DirectShow interface. • Live audio/video is encoded with WMA/MP3/GSM 6.10 - WMV/MPEG4 codecs in real time. • Hardware encoder appliances are supported for streaming hardware compressed content without software transcoding. • TCP, HTTP and MMS unicast, RTP multicast transport protocols are supported. • For HTTP delivery IIS web server is required on the server computer.
Unreal Media Server includes 3 major components • Streaming video recording : Streaming video recorders can record not only video streams but also many audio streams so sometimes they are also called streaming media recorders. There are different approaches that are used by the software to make the recording, depending on which stage of the process one taps into. In order, they are: • URL Snooping: Simplest is if the stream is served by simply requesting it, just as web pages are, as in an HTTP GET request: this will directly copy the encoded, streamed file. In this case, one simply needs to determine the URL, and then download that, either by pasting it into one's web browser (location box or "Open location..."), or via a specialized download manager. • Encoded capture: Some streaming is not via a simple request to an URL – in this case, to capture the stream requires some understanding and implementation of the particular streaming protocol (the encoded media stream is encapsulated within a network stream), either: passively / offline :- capturing the actual traffic and extracting it (via deep packet capture, using a packet sniffer), or actively / online :-implementing the streaming protocol / program enough to request the encoded data.
