Wowza Streaming Engine (known as Wowza Media Server prior to version 4) is unified streaming media server software developed by Wowza Media Systems. The server is used for streaming of live and on-demand video, audio, and RIAs (rich Internet applications) over IP networks to desktop, laptop, and tablet computers, mobile devices, IPTV set-top boxes, internet-connected TV sets, game consoles, and other network-connected devices. The server is a Java application deployable on the following operating systems: Linux, Mac OS X, Solaris, Unix, and Windows.

Wowza Streaming Engine can stream to multiple types of playback clients and devices simultaneously, including the Adobe Flash player, Microsoft Silverlight player, Apple QuickTime Player and iOS devices (iPad, iPhone, iPod Touch), 3GPP mobile phones (Android, BlackBerry OS, Symbian, etc.), IPTV set-top boxes (Amino, Enseo, Roku, Streamit and others),[1] and game consoles such as Wii, Xbox, and PS3.

Wowza Streaming Engine is compatible with standard streaming protocols. On the playout side, these include RTMP (and the variants RTMPS, RTMPT, RTMPE, RTMPTE), HDS, HLS, MPEG DASH, RTSP, Smooth Streaming, and MPEG-TS (unicast and multicast). On the live ingest side the server can ingest video and audio via RTP, RTSP, RTMP, MPEG-TS (unicast and multicast) and ICY (SHOUTcast / Icecast) streams. It also supports incoming streams via the RTSP and WOWZ protocols from mobile Android and iOS devices running the Wowza GoCoder mobile encoding application.

For on-demand streaming, Wowza Streaming Engine can ingest multiple types of audio and video files. Supported file types include MP4 (QuickTime container - .mp4, .f4v, .mov, .m4a, .m4v, .mp4a, .mp4v, .3gp, and .3g2), FLV (Flash Video - .flv), and MP3 content (.mp3).
