推荐答案

最可能的原因是您正在运行的特定iOS设备不包括硬件H264编码器.我认为3GS之前的iPhone版本没有硬件，但是我不确定iPad 1是否具有H264编码硬件.我知道iPad 2确实有此硬件.

The most likely cause is that the specific iOS device you are running on does not include the hardware H264 encoder. I think that versions of iPhone earlier than 3GS have no hardware, but I am not sure if the iPad 1 has H264 encoding hardware. I know iPad 2 does have this hardware.
