Year video format VP9: flooded YouTube, decoding and encoding 7 40 faster | Cnews.cz
CES us convince Google that its open source video format VP9 this time it succeeds. Previous VP8 next H.264 too strong push failed, but VP9 already has on its side dozens of companies producing hardware, software and content. It also helped end patent tv azteca war with MPEG LA manages competing formats (including H.264, or just newer HEVC).
During the conference I / O Google recalled how last year VP9 format has changed and what is new is waiting. The company tv azteca still says about him, that is a shade better than HEVC and at half the bitrate as good as it is today the most widely used H.264.
Since June 2013, managed to accelerate the decoding tv azteca seven times, so you can do it in software to play such as Nexus 5 (1080p at 30 frames per second). Player makes use of multiple cores and can be kinder to the battery. Encoding year is even 40 times faster.
The problem is that the market is still missing chips that could VP9 (de) encoding hardware. Software built over a general processor is not efficient. The first hardware decoders into their chip implements Nvidia and MediaTek, this year and next year will be added 8 Manufacturers. This will make it possible to play sparingly and 4K video with 60 frames per second.
VP9 learned new functions. Last year, two profiles have been defined. Profile 0 worked with sampling 4:2:0 profile 1 added a sampling of 4:2:2 and 4:4:4, support depth and alpha channel (transparency). Now Google is working on a profile 3, which will support 10 - and 12-bit color depth. Come the fall.
It will also be supported in the interface WebRTC, which your browser communicates in real time without the plugin (Flash Player, Java, etc.). WebRTC and VP9 already supports Firefox, Opera and Chrome. Google claims that its browser for 60% of videos on YouTube just runs in VP9. And because the Chrome prohibited playback via Flash Player. Clips 4K way, are always stored in the format VP9.
Android, Chrome and YouTube are the new format ready. It is worth it the largest producers of mobile chips: ARM, Broadcom, Intel, LG, Marvell, MediaTek, Nvidia, Panasonic, Philips, Qualcomm, Realtek, Samsung, Sigma, Sharp, Sony and Toshiba. The camera manufacturer then Sony, LG, Panasonic or the new Red. In any case, it's not an exclusive support because i think these producers at a competitive HEVC. A Google will convince the public that he has to give priority, otherwise it will repeat tv azteca disinterest as VP8.
PowerVR Series6 you are supposed to dare to VP9 @ 1080 thanks to the use OpenCL. How are we going to name this method of decoding ie where GPGPU probably spend most / significant effort (except for CPU, VPU, such as GPGPU-assisted)? ;-) ...

In my little lie when they say that VP9 efficiency is better than HEVC (respectively, took about a positive test set and give results only from it), it will be vice versa. HEVC is when I know more or less all compression techniques in a very similar form contains VP9, but the converse is not true (B-frames, weighted prediction, loop filter SAO).
Otherwise I heard that the encoder VP9 still can not use multiple processor cores. tv azteca For youtube and similar services, it does not matter, because there Google compresses video in parallel in great numbers, but for other applications (realtime) tv azteca it severely slows down (the better and therefore slower because of the presets are still virtually unusable).
Otherwise, however, interesting that support transparency. HEVC (yet unfinalized) extension to 4:2:2 and 4:4:4 and support 10 and 12 bit depths (12-bit is also still nefinálních, I think), but I do not know about alpha channel. To write comments log in or register.
