    The transcoding feature in Wowza Streaming Engine media server software is designed to make live adaptive bitrate delivery over HTTP easy. The Transcoder can ingest a single high bitrate live stream and create multiple lower-bitrate renditions on the fly, which are keyframe-aligned for adaptive bitrate delivery. Synchronized Multimedia Integration Language (SMIL) files enable you to group the high bitrate stream and the new renditions together in logical groups for live adaptive bitrate delivery.

    This article explains how to use a SMIL file with transcoded or transrated streams created by Wowza Transcoder. ...

    Wowza DRM technology in Wowza™ media server software provides integration with third-party digital rights management (DRM) key management systems to add on-the-fly encryption for live and video-on-demand workflows. For live workflows, per-stream encryption is available with the ability to rotate keys. For on-demand workflows, per-asset and per-session encryption is available with the ability to rotate keys. Both live and on-demand key rotation support is available for Apple HTTP Live Streaming (Apple HLS).

    Currently, integration is supported for the following key management systems:

    • BuyDRM KeyOS. Supports Microsoft PlayReady protected Apple HLS and Microsoft Smooth Streaming playback with BuyDRM players on iOS-based devices (iPhone/iPad) and Windows Phone devices.

    • EZDRM. Supports Smooth Streaming playback with Silverlight clients.

    • Verimatrix VCAS. Supports Apple HLS playback with ViewRight clients on iOS-based devices, Android devices, PCs, and set-top boxes.

    Requirements

    Wowza DRM works with the following Wowza media server software versions:

    • Wowza Streaming Engine™

    • Wowza Media Server™ (version 3 and later)

    Licensing Wowza DRM

    Perpetual and Subscription licenses for Wowza Streaming Engine software provide for unlimited connections to the media server software instance and enable use of the Wowza DRM technology that's integrated with each licensed instance.

    Note: If you purchased a license for Wowza media server software before January 1, 2015, contact sales@wowza.com to learn more about how to license Wowza DRM.

    Wowza Transcoder is a real-time video transcoding and transrating solution in Wowza™ media server software. As a transcoding solution, it can ingest a non-H.264/VP8/VP9 video and non-AAC/MP3/Vorbis/Opus audio source stream and convert it to outbound H.263/H.264/VP8/VP9 video and AAC/MP3/Vorbis/Opus audio. Multiple outbound renditions with aligned keyframes can be created from the single input stream. As a transrating solution, it can ingest an H.264 video and AAC/MP3 audio source stream and create a full set of output renditions that are keyframe-aligned to the original source. The aligned keyframes in the encoded output renditions enable adaptive bitrate delivery from the Wowza media server over Adobe HDS, Apple HLS, Microsoft Smooth Streaming, MPEG-DASH, and RTMP streaming protocols to multiple devices.

    Supported video and audio formats

    Wowza Transcoder can decode and encode the following video and audio codecs:

    Video decoding (source streams)
    Audio decoding (source streams)
    Video encoding (outbound renditions)
    Audio encoding (outbound renditions)
    H.264
    MPEG-2
    MPEG-4 Part 2
    AAC
    G.711 (-law and A-law)
    MPEG-1 Layer 1/2
    MPEG-1 Layer 3 (MP3)
    Speex
    H.264
    H.263v2
    VP8
    VP9
    AAC
    Vorbis
    Opus

    Note: Wowza Streaming Engine™ 4.5.0 or later is required to use the VP8/VP9 video codecs and Vorbis/Opus audio codec encoding.

    Hardware requirements

    Wowza Transcoder is supported on 64-bit versions of the Windows and Linux operating systems (32-bit versions aren't supported). The OS X operating system isn't supported.

    Wowza Transcoder can be configured to take advantage of hardware acceleration, which is recommended but not required. If your configuration doesn't include hardware acceleration, then a built-in software encoder is invoked. For recommended workstation and server-level hardware to support Intel Quick Sync Video, see Server specifications for Intel Quick Sync acceleration with Wowza Transcoder. For a list of supported NVIDIA graphics cards that are compatible with Wowza Transcoder, see Server specifications for NVIDIA NVENC and NVIDIA CUDA acceleration with Wowza Transcoder.

    Licensing Wowza Transcoder

    Perpetual and Subscription licenses for Wowza Streaming Engine software enable unlimited use of the Wowza Transcoder technology that's integrated with each licensed media server instance. The integrated Transcoder can decode an unlimited number of inbound live streams and encode an unlimited number of outbound live renditions (subject to CPU/hardware limitations).

    Note: If you purchased a license for Wowza media server software before January 1, 2015, contact sales@wowza.com to learn more about how to license Wowza Transcoder.

    Wowza nDVR technology in Wowza™ media server software provides the ability to record a live stream with while simultaneously allowing users to play, pause, resume, and rewind the recorded stream. You can configure settings and properties to control the archive strategy and availability of the recorded streams.

    The following HTTP-based streaming protocols support DVR playback of nDVR-recorded streams:

    • Adobe HTTP Dynamic Streaming (Adobe HDS/San Jose)

    • Apple HTTP Live Streaming (Apple HLS/Cupertino)

    • Microsoft Smooth Streaming (Smooth)

    Setup for client DVR playback of the recorded streams is similar to playback of live streams from a Wowza media server.

    Requirements

    Wowza nDVR works with the following Wowza media server software versions:

    • Wowza Streaming Engine™

    • Wowza Media Server™ (version 3 and later)

    Wowza nDVR requires that the audio and video in the inbound live stream to be aligned. Live streams with short keyframe intervals and aligned audio and video work best.

    Licensing Wowza nDVR

    Perpetual and Subscription licenses for Wowza Streaming Engine software provide for unlimited connections to the media server software instance and enable use of the Wowza nDVR technology that's integrated with each licensed instance.
