Wowza Media Server流媒体服务器

Supported Media

Wowza Media Server主要支持H.264 编码的视频格式。音频的话,主要支持mp3等格式。

Wowza Media Server 3 supports the following media file formats: FLV (Flash Video), MP4 (QuickTime container) and MP3 content (see table below for common file extensions). To play video on demand content, the proper prefix must be prepended to the file name to create a stream name. For example to play the MP4 file mycoolvideo.mov use the stream name mp4:mycoolvideo.mov. The following table lists the more common file type prefixes (for a complete list consult the User’s Guide):

flv: FLV (Flash Video – this is the default media type so the qualifier and the file extension can be omitted)

Example: “flv:mycoolvideo.flv”

mp4: MP4 (QuickTime container – .mp4, .f4v, .mov, .m4v, .mp4a, .3gp, and .3g2)

Example: “mp4:mycoolvideo.mov”

mp3: MP3 (.mp3)

Example: “mp3:mycoolsong.mp3″

smil: SMIL (XML files used to configure multi-bitrate streams – .smil)

除此之外的其它支持格式要转码:
Wowza Transcoder AddOn

Wowza Transcoder AddOn is a real time video transcoding and transrating solution. It can decode and re-encode audio and video in multiple formats properly key-frame aligned for multi-bitrate deliver. Here are a few common scenarios:

Transcoding
Take in a non-H.264 AAC media stream and convert it to a properly key frame aligned set of H.264 AAC multi-bitrate media streams.

Transrate
Take in a H.264 AAC media stream and create multiple renditions that are key frame aligned to the source stream for adaptive bitrate delivery.

Wowza Transcoder supports the following video and audio formats:

Video (decoding)

  • MPEG2
  • MPEG4 Part 2

Video (encoding)

  • H.264

Audio (decoding)

  • MP3
  • MPEG1 Part 1/2
  • Speex
  • G.711 (a-law and mu-law)

Audio (encoding)

  • AAC

Wowza nDVR AddOn (beta)

Wowza nDVR provides the ability to record a live stream with Wowza Media Server 3 while simultaneously allowing users to play, pause, resume and rewind the recorded stream. Custom configuration allows control over the archive strategy and availability of your recorded streams.

Wowza nDVR is supported on all Wowza Media Server 3 platforms. Setup for client playback of recorded streams is similar to playback of live streams from Wowza Media Server.
