Best Answer-推荐答案
来自 Apple 文档:
This class plays any movie or audio
file supported in iOS. This includes
both streamed content and fixed-length
files. For movie files, this typically
means files with the extensions .mov,
.mp4, .mpv, and .3gp and using one of
the following compression standards:
H.264 Baseline Profile Level 3.0
video, up to 640 x 480 at 30 fps. (The
Baseline profile does not support B
frames.) MPEG-4 Part 2 video (Simple
Profile) If you use this class to play
audio files, it displays a white
screen with a QuickTime logo while the
audio plays. For audio files, this
class supports AAC-LC audio at up to
48 kHz, and MP3 (MPEG-1 Audio Layer 3)
up to 48 kHz, stereo audio.
