WebM’s Hardware decoder design is now at the fourth version with significantly improved decoder that extends battery life on mobile devices.
“In this release, our focus has been on optimizing the VP8 bitstream decoder. The new architecture helps the IP run at 13% higher operating frequency allowing the decoder chips to reach higher frame rates or do multi-channel decoding more easily. At the same time, the new implementation has reduced the decoder’s logic gate count by 6% which directly cuts the production cost of each chip incorporating a WebM hardware decoder. Furthermore, the revamped design allows us to do even more optimizations for the next release. With future video requirements in mind, we designed Driver to decode up to 4k by 4k video resolutions.”
