VP8

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。

Until we get some hard evidence that VP8 is safe , I would be extremely cautious .

在我们得到确凿证据证明VP8是安全的之前，我会非常谨慎。

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。

After the purchase , the free software foundation immediately called for Google to open-source VP8 .

这笔收购完成后，自由软件基金会（FreeSoftwareFoundation）立刻呼吁谷歌公司（Google）对VP8进行开源。

On2 technologies made Theora and VP8 , high performance video codecs for online streaming .

On2Technologies公司推出过视频压缩技术Theora和视频编解码器VP8，它们都是在线流媒体的高性能视频编解码器。

Google did open-source VP8 that may as a crucial piece of its video format , WebM .

当年5月，谷歌就对VP8做了开源，将其作为其媒体文件格式WebM的重要组成部分。

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。

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。

Since Google is not indemnifying users of VP8 from patent lawsuits , this is even more of a potential problem .

由于Google并没有保护VP8用户能够免于专利诉讼，这将成为一个潜在的问题。

The killer mistake that VP8 has made here is not making macroblock-level quantization a core feature of VP8 .

VP8在这里犯的致命的错误是没有把宏块级量化作为其核心功能。

For quantization , the core process is basically the same among all MPEG-like video formats , and VP8 is no exception .

对于量化，所有与MPEG近是的视频格式，核心处理流程基本上是相同的，VP8也不破例。

WebP is based on a algorithm borrowed from the VP8 codec used by WebM to encode and compress video .

WebP所根据的算法借用自WebM用来压缩视频的VP8编码解码器。

The VP8 interpolation filter is likely slightly better , but will definitely be slower to implement , both encoder and decoder-side .

VP8的插值过滤器可能稍好，但使成为事实起来肯定会慢，包括编码器端和解码器端。

The prediction scheme in VP8 is a bit odd & worse , the section of the spec covering this contains no English explanation , just confusingly-written C code .

VP8预测方案有点奇怪，糟糕的是，在规范中没有涉及这个的英文的解释，只是笼统的C代码。

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。

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。

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。

Also supported is the video tag ; out of the box , it supports hardware accelerated H.264 video decoding – though you can add WebM / VP8 plugins for decoding other codecs if you want to .

除此之外，还支持video标记，易于使用，支持硬件加速的H.26视频解码&你可以选择添加WebM/VP8插件用于其它解码器。
