What is it all about?
WebM is a free open source media file format used primarily to transfer any video to the web. is a degenerate version of Truska container format but the sound can only be encoded in Vorbis and video can only be VP8 or VP9 encoding. the common browsers Chromium / Chrome, Firefox and Opera knows introduce WebM videos while Internet Explorer and Safari require an external plugin for displaying movies.
* Encoding of VP9 Profile 0 (8-bit 4:2:0) * Single core for 2160p@30fps * Unprecedented real-time encoding quality * Up to 70% better than H1 VP8 / H.264 hardware encoder * Up to 40% better than real-time libvpx VP9 software encoder * RD-optimal mode selection * Scalable effort level increasing quality gain at SD * Low bandwidth with reference frame compression * Full real-time communication feature set 8 reference frames (two simultaneously) * Dynamic reference frame scaling * Tile encoding and streaming * SoC connectivity: 128/256 bit AXI master, AXI, AHB or APB slave, Configurable endianness
