Further, the embodiment of the present invention discloses a kind of caching method for determining speed based on AVPlayer player.
It is the flow diagram of another embodiment of the present invention referring to Fig. 2, Fig. 2, in the present embodiment, this method comprises:
S201, the acquisition instruction that speed is cached to target object is received；The target object is audio and/or video；
S202, FTP client FTP is obtained in the first time point of current time；The AVPlayer player is obtained in institute
State the first cache-time point of target object described in first time point cache；
S203, second time point of the FTP client FTP after being spaced scheduled duration is obtained；Obtain the AVPlayer
Second cache-time point of player target object described in the second time point cache；
S204, using the difference of second time point and the first time point as the target time interval, by institute
The difference of the second cache-time point and the first cache-time point is stated as the cache-time interval；
S205, according to the acquisition instruction, obtain the target object in the target bit rate at the cache-time interval；
S206, using the cache-time interval and the target bit rate, determine the target object in the target
The caching total amount of byte of time interval；
S207, according to the caching total amount of byte and the target time interval, determine the caching speed of the target object
Degree, and it is shown in the display interface of AVPlayer player.
In the present embodiment, when determining target time interval and cache-time interval, it can record current point in time as the
One time point startTime, while record has currently cached total time o'clock as the first cache-time point bufferDuration
(unit second), the first time point can be 16:00:00, which can be with are as follows: 5s；After waiting preset duration,
The now time o'clock is recorded as the second time point nowTime, record has cached total time o'clock as the second cache-time now
Point nowBufferDuration, second time point can be 16:00:01, which can be with are as follows: 10s.
As can be seen that the present embodiment in target time interval be nowTime-startTime namely 16:00:01 with
The difference of 16:00:00, i.e. 1s, also, the target time interval is identical as scheduled duration, also, the first time point and second
Time point is all the time point of FTP client FTP, and acquisition modes can call directly iOS system acquisition, such as obtain at the first time
Point startTime are as follows: let startTime=Date ().
Be divided between cache-time in the present embodiment nowBufferDuration-bufferDuration namely 10s with

Target object described in the AVPlayerItem object acquisition of FTP client FTP be again may be by the cache-time interval
Target bit rate, such as: if target object is audio-video, the bit rate of all track of video, audio track is obtained, is then asked
With obtain gross bit rate totalDataRate, which can equally obtain according to AVPlayerItem calculation and object in iOS system
It arrives:
Further, pass through formula cacheSpeed=(nowBufferDuration-bufferDuration) *
TotalDataRate/ (nowTime-startTime) can calculate the caching speed of target object, wherein
NowBufferDuration-bufferDuration is cache-time interval, and totalDataRate is target bit rate,
(nowBufferDuration-bufferDuration) * totalDataRate is to cache total amount of byte, nowTime-
StartTime is target time interval.
As can be seen that this mode for calculating caching speed provided in this embodiment, only according to iOS system frame
The parameter provided under AVFoundation can obtain caching speed, without being made any adjustments to playing flow, calculation method letter
It is single and accurate.
Further, in the present embodiment, described according to the acquisition instruction, the target object is obtained between the object time
Every interior caching of target object cache-time interval and the target object the cache-time interval target bits
Rate, comprising:
Judge whether the acquisition instruction is real-time acquisition instruction；
If so, executing the acquisition target object between the object time continuously in each target time interval
Every interior caching of target object cache-time interval and the target object the cache-time interval target bit rate
The step of；
If it is not, executing the acquisition target object in target then in the target time interval from current time
Between be spaced in caching of target object cache-time interval and the target object the cache-time interval target ratio
The step of special rate.
That is, two classes can be divided into for the acquisition instruction in this programme, if it is real-time acquisition instruction, then
Target time interval can be set at lesser interval, such as 1s, then needing continuously after receiving acquisition instruction every
Caching speed will be calculated in a 1s, and is shown in the display interface of AVPlayer player, so for a user, caching
It speed, that is, real-time update and shows on the screen in real time；The triggering form of the acquisition instruction can be with are as follows: play audio and/or
It when video, is actively triggered by system, so as to real-time display in the display interface, real-time display caching can also be wanted in user
When speed, shown on the display screen by way of active triggers.
If the acquisition instruction is not real-time acquisition instruction, after at this moment receiving the acquisition instruction, only from current time
Target time interval in obtain caching speed, such as: user by click caching speed obtain icon, obtain current caching
At this moment speed can calculate the caching speed in the target time interval from current time by this programme, and be shown in boundary
Face just terminates, the caching speed without calculating next target time interval.
As can be seen that type of this programme according to acquisition instruction, provides two kinds of caching speed acquisition modes, one kind is real
When obtain the mode of caching speed, real-time display caching speed, another kind is only obtains and shows the caching speed at current time
Mode, user can set according to actual needs, to improve and use for a variety of caching speed display modes that user improves
Family experience.
