AVPlayer
有一些新功能(适用于iOS 10+),您可以试用。我自己使用它,一切正常。
/*!
@method playImmediatelyAtRate:
@abstract Immediately plays the available media data at the specified rate.
@discussion
When the player's currentItem has a value of NO for playbackBufferEmpty, this method causes the value of rate to change to the specified rate, the value of timeControlStatus to change to AVPlayerTimeControlStatusPlaying, and the receiver to play the available media immediately, whether or not prior buffering of media data is sufficient to ensure smooth playback.
If insufficient media data is buffered for playback to start (e.g. if the current item has a value of YES for playbackBufferEmpty), the receiver will act as if the buffer became empty during playback, except that no AVPlayerItemPlaybackStalledNotification will be posted.

- (void)playImmediatelyAtRate:(float)rate NS_AVAILABLE(10_12, 10_0);
另外你可以看看这个变量(可以使用国际志愿者组织来说太):
/*!
@property reasonForWaitingToPlay
@abstract Indicates the reason for waiting when the value of timeControlStatus is AVPlayerTimeControlStatusWaitingToPlayAtSpecifiedRate
@discussion
When the value of timeControlStatus is AVPlayerTimeControlStatusWaitingToPlayAtSpecifiedRate, this property describes why the player is currently waiting. It is nil otherwise.
You can use the value of reasonForWaitingToPlay to show UI indicating the player's waiting state conditionally.
This property is key value observable.
Possible values are AVPlayerWaitingWithNoItemToPlayReason, AVPlayerWaitingWhileEvaluatingBufferingRateReason, and AVPlayerWaitingToMinimizeStallsReason.

@property (nonatomic, readonly, nullable) NSString *reasonForWaitingToPlay NS_AVAILABLE(10_12, 10_0);
