We'll start by going through the core features of VP8.
我们将首先浏览一遍vp8的核心特点。
One more thing to note is the data partitioning scheme used by VP8.
还有一点要注意的是VP8中数据的分区方案。
Now that I've gotten that out of my system, let's get back to VP8 itself.
现在我已经摆脱了它(指规范?译者注)了,让我们回到VP8本身。
This post is primarily aimed at discussing issues relating to the VP8 video format.
这篇博文的主要目的是讨论VP8视频格式的有关问题。
I'm guessing that the current VP8 software simply evolved from the original VP7 software.
我猜测,目前VP8软件只是原vp7软件的一个简单演变。
The purpose was the acquiring of On2's video compressing and encoding technology known as VP8.
Google此举的目的在于得到On2的视频压缩与编码技术,即我们所熟知的VP8。
Third, VP8's filter omits most of the adaptive strength mechanics inherent in H. 264's filter.
第三,VP8的过滤器忽略了大部分H . 264中自适应过滤器的力学强度的过滤。
VP8 USES an arithmetic coder somewhat similar to H. 264's, but with a few critical differences.
VP8使用算术编码器有点类似H . 264的,但有几个关键的差异。
They aren't even ready to finalize the bitstream format, let alone switch the world over to VP8.
他们甚至还没有确定码流格式,更不用说在全球推广VP8。
Insiders reckon VP8 USES only half the bandwidth of H.264 while delivering an even better picture.
内部人士认为VP8只使用了H . 264一半的频宽,却播放出更优质的画面。
VP8 is an open source video compression format supported by a consortium of technology companies.
VP8是一个有几家公司联合支持的开源视频压缩格式。
There are, however, rumors that VP8 might infringe on some of the H264 patents, so stay up to date.
然而,传言vp8可能侵害一些H264专利,故总是保持最新更新。
I have already received a complaint from a hardware developer about this specific feature with regard to VP8.
我已经收到了硬件开发人员关于VP8这方面的特定功能的投诉。
Since Google is not indemnifying users of VP8 from patent lawsuits, this is even more of a potential problem.
因为谷歌并不确保VP8的用户免于专利诉讼,这更是一个潜在的问题。
Even VC-1 differed more from H.264 than VP8 does, and even VC-1 didn't manage to escape the clutches of software patents.
与VP8相比,VC - 1与H . 264之间的差别更大,但它还是没有逃过软件专利的手爪。
However, since Google's announcement, questions have been raised around the licensing and the performance of the VP8 codec.
然而,自从Google发表声明以来,多方都在担心VP8codec的许可以及性能问题。
Keep in mind that this is not representative of what you can get out of VP8 now, but rather what could be gotten out of VP8.
请记住,这不是典型的你现在能从VP8中得到什么,而是你曾经能从VP8中得到的。
The VP8 spec by comparison is imprecise unclear and overly short leaving many portions of the format very vaguely explained.
相比之下,VP8的规范是不确切的,不明确,过于短,还留下许多关于格式的很含糊的解释。
I would expect, with equally optimized implementations, VP8 and H. 264 to be relatively comparable in terms of decoding speed.
我期望经过同样的优化后的实现,VP8和H . 264在解码速度方面能具有可比性。
The VP8 spec, by comparison, is imprecise, unclear, and overly short, leaving many portions of the format very vaguely explained.
相比之下,VP8的规范是不确切的,不明确,过于短,还留下许多关于格式的很含糊的解释。
Visual results: Unfortunately, since the current VP8 encoder optimizes entirely for PSNR, the visual results are less than impressive.
视觉效果:不幸的,因为目前的VP8编码器完全是为信噪比做优化,视觉效果远远达不到令人印象深刻的程度。
Now, Google has backtracked on its initial decision and released VP8 under a fairly standard BSD license, earning the praise of the OSI.
现在,谷歌已经回到了它最初的选择,在标准BSD许可之下发布了VP8,赢得了OSI的极大赞誉。
The paper also discusses how these features benefit VP8 in achieving high compression efficiency and low decoding complexity at the same time.
本文还讨论这些特性是如何使VP8成就高压缩效率的同时具有低编码复杂度的。
The MPEG-LA, having earlier indicated that it might start a patent pool similar to H.264, has now announced a call for patents for a VP8 patent pool.
MPEG-LA(表示会像H.264那样启动专利联营)现在宣布要为VP8申请专利。
Secondly, when filtering between macroblocks, VP8's filter has wider range than the in-macroblock filter — H. 264 did this, but only for intra edges.
第二,当在宏块之间的过滤的时候,VP8的过滤器比在块内部过滤有更广泛的范围,H.264只在内部边缘会这样做。
Anyways, this means that I'm not going to go easy on On2; they've had (at least) 6 years to work on VP8, and a much larger dev team than x264's to boot.
不管怎么说,这意味着我不会继续轻易放过On 2公司,他们有(至少)6年的时间来完善VP8,和一个比x264更大的开发团队。
VP8 is simply way too similar to H.264: a pithy, if slightly inaccurate, description of VP8 would be “H.264 Baseline Profile with a better entropy coder”.
VP8与H.264太像了:一言以蔽之,如果描述不那么严格的话,可以将VP8看作是“一个带有更好的熵编码的H.264BaselineProfile”。
Note that these Numbers are a "best-case" situation: we're testing all three optimized for PSNR, which is what the current VP8 encoder specializes in as well.
请注意,这些数字是“最佳”的情况:我们正在测试三个编码器都为峰值信噪比做了专门优化,而这也正是VP8编码器规范当前做的。
This means that both the code and the codec are available for practically any use, with the exception that if you sue Google, you immediately lose your VP8 license.
这意味着无论用于何种目的都可以使用其代码与codec,但如果你控告Google,那么将立刻失去VP8的许可权。
