[请教]求真相，同画质码率比H.264低50%？

iiiiuuuu@2010-02-24 21:18

在网上看到关于有组织跪求google开放收购的On2公司的高性能视频编解码器VP8的源代码的消息

说是同画质码率比H.264低50%，很夸张啊，所以到这里来求真相。

另外在on2网站上发现了它提供的Flix Cloud，这公司现在用亚马逊的云计算平台提供云视频压制服务了 http://www.flixcloud.com/

以后压片都不用下到自己的机子上来了，直接在网上压完就发布了，这时代变化快啊。不过就是价格贵了些。

所有的商业编码器都比它们的竞争对手质量好30%，速度快50%

Where does x264 fit in all this? H.264 is certainly not going away, not for quite a while. In most sane parts of the world, software patents are a non-issue. But in the end, none of it matters for x264: we will continue our quest to create the best video compression software on Earth. Unlike Adobe, we don’t sit complacent when we are the best; we keep trying to become better. We add new features, improve compression, support new platforms, improve performance, and there’s far more to come. We don’t care that many H.264 encoders are so bad that they can be beaten by Theora or Xvid. We don’t care if VP8 comes out; that’s just another encoder to beat. We are here to ensure that the best choice is always free software by constantly making free software better.

很好，很有霸氣……
話說snow開發地咋樣啦？

SNOW现在应该不在开发中，Michael大神貌似没人赞助就不搞了

居然这样……
看来x264暂时没啥对手了……

x264的问题就在于不太适合商业应用。一个是GPLv2，一个就是稳定性太差，接口还三天两头变。
