FLV 和 H264 哪种 Flash 视频格式压缩率更高？
我阅读了一篇 Adobe 文章，其中演示了 H.264 视频播放支持闪存播放器。以这种格式编码的视频是否比典型的 FLV 视频压缩程度更高？从现在开始我应该在网站上放置视频时使用这种格式吗？
I read an Adobe article which demonstrated H.264 video playback support in Flash Player. Would video encoded in this format be more compressed than typical FLV videos? Should I be using this format for video I place on websites from now on?

H.264 是最先进的高质量编解码器之一。流媒体行业普遍正在朝这个方向发展，包括FLV的作者Adobe。
转向 H.264 为人们节省了带宽费用，和/或允许他们提高质量。所以...
是的，您应该使用 h.264 而不是 FLV 文件中的 H.263 或 VP6。
为了部分地反驳 Cornel Creanga 的答案，请将 H.264 放在 FLV 文件中Adobe 不推荐。虽然技术上可行，但这种情况并不常见，而且存在问题，而且 FLV 容器无法支持 h.264 用于发挥其魔力的所有高级功能。不要尝试。
H.264 is one of the most advanced high quality CODECs out there. The streaming media industry is generally moving that way, including Adobe who is the author of FLV.
This move to H.264 is saving folks money in bandwidth, and/or allowing them to increase quality. So...
Yes, you should be using h.264 instead of H.263 or VP6, which are in FLV files.
To contradict Cornel Creanga's answer, partially, placing H.264 in FLV files in not recommended by Adobe. While technically possible, it is uncommon, problematic and the FLV container cannot support all of the advanced features that h.264 uses to work it's magic. Don't try it.
FLV不是视频编解码器。它是一种容器格式。您可以在其中放置不同类型的媒体，例如 wav 声音等。
h264 还具有当前可用的最佳压缩率。它的缺点是解码 h264 视频相对昂贵。
@Stu：甚至 youtube 也支持 h264 压缩。我不知道他们在发布之前是否将其转换为另一种格式，但我不明白为什么不应该将 h264 视频放入 FLV 容器中。毕竟它只是一个视频编解码器，有什么“魔力”不支持呢？
FLV is not a video codec. It is a container format. You can place different sorts of media in it like wav sounds and so on.
Also h264 has the best compression that is currently available. Its downside is that it is relatively expensive to decode a h264 video.
@Stu: Even youtube supports h264 compression. I don't know if they convert it into another format before publishing it, but I don't see why one shouldn't place a h264 video into a FLV container. After all, its just a video codec, what kind of "magic" is not supportet?
FLV 文件包含使用各种编解码器编码的视频：VP6、H.263、H.264。我想您通常指的是 VP6 编码？如果是，也许这篇文章可以帮助您 http://support.on2.com/h264_faq.php。
The FLV files contains video encoded with various codecs: VP6, H.263, H.264. I suppose that by typical you are referring to the VP6 encoding? If yes maybe this article can help you http://support.on2.com/h264_faq.php.
