Video Breakthroughs

Mozilla is drafting a proposal for a new Web standard called MediaStream Processing that introduces JavaScript APIs for manipulating audio and video streams in real time. The specification is still at an early stage of development, but Mozilla has already started working on an implementation for testing purposes.

Mozilla's Robert O'Callahan, the author of the MediaStream Processing API proposal draft, released experimental Firefox builds that include MediaStream Processing support. He has also published a set of demos (note: you need to run the experimental build to see the demos) that illustrate some of the functionality defined by the specification.

The demos show how the APIs can be used to perform tasks like rendering a visualization of a video's audio track in a Canvas element while the video is playing. It also shows how the APIs can be used for mixing tasks, like implementing a cross-fade between two audio streams, dynamically adjusting the volume of a video, and programmatically generating audio streams.

OpenClove, an innovator in providing cloud mobile and video solutions, announces the support of WebRTC on its OpenClove Video Exchange (OVX). The development enables any application to embed multi-party video in web services and mobile apps, across any device or network. This capability brings together the power of OVX, a cloud based Media Resource Function (MRF) providing real-time audio and video mixing and processing, with the benefits of WebRTC, to deliver communications natively in web pages. Web services providers and application developers adopting WebRTC can now deliver a range of live video sharing and multi-party use cases for consumers and enterprise users.

OVX supports multiple audio and video codecs in a single video session, such as VP8 for WebRTC and H.264 for IMS, to assure seamless delivery of real-time communications across heterogeneous clients."
