New features and functionality in Wowza Streaming Engine 4.8.11 are below.
Beamr encoding and decoding for H.264 and H.265 video
Wowza Streaming Engine 4.8.11 adds support for Beamr software video encoding and decoding for the H.264 and H.265 codecs. Compared to the existing MainConcept encoder and decoder implementations, using the Beamr encoder or decoder implementations offers improved video quality with similar CPU usage. With support for Beamr, MainConcept software encoding and decoding are deprecated for H.264 and H.265 video. For more information about configuring Beamr encoding and decoding and the deprecation of MainConcept, see the following the articles:
Replacing missing video frames to ensure a consistent frame rate
With Wowza Streaming Engine 4.8.11, you can prevent streams from buffering and displaying artifacts for smoother, more continuous video playback by replacing missing video frames and ensuring a consistent frame rate using the Transcoder. Replacing missing frames with the last successfully decoded frames allows for maintaining a specific output frame rate even when the source video is missing frames and drops below the desired output frame rate. You can enable a consistent frame rate using either a strict frame rate for constant frame rate video or minimum frame rate for variable frame rate video. For more information about replacing missing video frames and ensuring a consistent frame rate, see the following the article:
Protecting WebRTC playback with SecureToken
Wowza Streaming Engine 4.8.11 adds support for secure authentication of WebRTC playback using SecureToken protection. You provide the SecureToken information to Wowza Streaming Engine through JSON data passed over the WebSocket. For more information about using SecureToken to protect WebRTC playback, see the following the articles:
