Only H264 has hardware decoding on iOS.
This means comparable video performance with native player only for H264
and slugish (at best) decoding for Sorenson and VP6 (even with low resolutions).
"AIR 3 for iOS uses the StageVideo object for H.264 video with hardware decoding, with limited supported for NetStream functionality. AIR 3 for iOS also supports On2 and Sorenson codecs through the StageVideo object. This support does not use hardware decoding, and it does not limit NetStream functionality."

FLV and MP4 are encapsulation formats.
FLV can contain VP6+MP3 or H264+AAC (or any of them taken alone).
MP4 can contain H264+AAC.
The docs don t say anything about FLV not beeing supported on iOS.
However, on iOS, if FLV/H264 won t play, you won t be able to remux it to MP4 on the fly because of the following restriction (otherwise you would lose hardware decoding):
"Note: This method is not supported for H.264 video in AIR 3.0 for iOS."

关于Sorenson或VP6, 不得因飞机残渣而被起诉(他们应负责)。
除非你计划做一些非常先进的工作,否则,你就不需要任何途径,如在游戏期间不中断地在飞机上开标。
生计流离需要类似于 app的 something。 由于H264硬件脱编码是必需的,而且没有软件模式,因此,你获得了H264的活流。
"It turns out that real-time streaming of an H264 video does not render on iOS devices in Adobe Air. Other video codecs will work (H263), but not for H264. You ll consume the feed, but will only hear audio. I confirmed this after talking with members of the Adobe Air development team."

H264的编码在不同 Apple果ARM CPU上表现得好,这真的取决于视频编码环境(B-frame或键盘、比目等),而且你有动态内容、静态内容、快速开关、分辨、彩色粉等等。
Conclusion:
Use FLV or MP4 (whichever suits you best), with H264+AAC inside.
Experiment with encode settings, or lots of videos of which you are targeting (if any).
Determine which is the lowest (oldest) iOS device you want to target, and test on that.
