Guest blogger Tomi Jalonen is Director of Product Marketing for Hantro video IP at VeriSilicon2011 is shaping up to be an exciting year at
VeriSilicon Holdings in terms of WebM support. With the new year upon us, I want to share some updates about the work we are doing at VeriSilicon to move the WebM platform forward.
VeriSilicon has been a longtime partner of On2/Hantro (Hantro is the video IP brand that Google acquired with On2 Technologies) and we were among the first hardware partners to commit to WebM video when the codec was open-sourced last year. After promoting WebM to the semiconductor industry during 2010, we're excited that at CES 2011 the first tablet supporting WebM with full 1080p resolution was demonstrated. VeriSilicon licensed the WebM IP to this tablet manufacturer and provided engineering support to bring the technology to the showroom floor.
In addition to licensing IPs, this year we'll be taking the WebM experience a step further by taping out several application processor chips--including the WebM video IP for Android phones, xPad, and Google TV--to accelerate the deployment of WebM and HTML5 video playback into the market.
The entire VeriSilicon team is very excited about the future of WebM. We believe that the availability of high-quality, optimized WebM hardware video IP, combined with other
VeriSilicon audio and multimedia IP, will be a key ingredient for semiconductor companies to create competitive consumer products. After the launch of WebM, the interest in hardware-accelerated WebM video has been immense and we will continue working with the WebM Project to enable WebM and VP8 in many more chips in 2011.

Hello from the frigid city of
Oulu, in the far north of Finland. Our WebM hardware development team, formerly part of On2 Technologies, is now up-to-speed and working hard on a number of video efforts for WebM.
- VP8 (the video codec used in WebM) hardware decoder IP is available from Google for semiconductor companies who want to support high-quality WebM playback in their chipsets.
- The Oulu team will release the first VP8 video hardware encoder IP in the first quarter of 2011. We have the IP running in an FPGA environment, and rigorous testing is underway. Once all features have been tested and implemented, the encoder will be launched as well.
WebM video hardware IPs are implemented and delivered as
RTL (VHDL/Verilog) source code, which is a register-level hardware description language for creating digital circuit designs. The code is based on the Hantro brand video IP from On2, which has been successfully deployed by numerous chipset companies around the world. Our designs support VP8 up to 1080p resolution and can run 30 or 60fps, depending on the foundry process and hardware clock frequency.
The WebM/VP8 hardware decoder implementation has already been licensed to over twenty partners and is proven in silicon. We expect the first commercial chips to integrate our VP8 decoder IP to be available in the first quarter of 2011. For example, Chinese semiconductor maker
Rockchip last week
demonstrated full WebM hardware playback on their new RK29xx series processor at CES in Las Vegas (video below).
Hardware implementations of the VP8 encoder also bring exciting possibilities for WebM in portable devices. Not only can hardware-accelerated devices play high-quality WebM content, but hardware encoding also enables high-resolution, real-time video communications apps on the same devices. For example, when VP8 video encoding is fully off-loaded to a hardware accelerator, you can run 720p or even 1080p video conferencing at full framerate on a portable device with minimal battery use.
The WebM hardware video IP team will be focusing on further developing the VP8 hardware designs while also helping our semiconductor partners to implement WebM video compression in their chipsets. If you have any questions, please visit our
Hardware page.
Happy New Year to the WebM community!

Silicon video IP maker Chips&Media
has begun shipping its CODA960 multiformat HD video hardware core, which supports up to 1080p60 playback of VP8 video. VP8 is the video codec used in WebM.
Chips&Media representatives went on the road recently to show the industry's first
FPGA demonstration of WebM 1080p hardware decoding. For more information, visit the
Chips&Media web site.

Guest blogger Charlie Good is CTO and co-founder of Wowza Media SystemsAs a company, we at Wowza move fast and like to tinker. When WebM was announced in May, we saw it as a promising new approach to HTML5 video and decided to do an experiment with live WebM streaming over http.
Adding WebM VP8 video and Vorbis audio to the other encoding formats that our server supported was easy (we designed the Wowza server to be codec-agnostic). We then created a WebMfile and implemented WebM HTTP streaming.
We originally created the demo as a proof-of-concept for the
IBC show in September, 2010 but have made it available to
watch on our web site.
The file is streamed live (more precisely, "pseudo-live") over http using the
Wowza server-side publishing API (PDF). The result is very impressive; playback starts fast and the VP8 image quality is fantastic.
You will need a
WebM-enabled browser or
VLC media player 1.1.5 to view the live stream.
