Hereafter can the seriality of display time detecting picture frame based on each picture frame, generate described video
Testing result, in the present embodiment, the testing result of video includes: card testing result and frame losing detection
As a result, specific as follows.
Wherein, the card generating video pauses inspection result, specifically may include that step 209, step 211
And step 213；Generate the frame losing testing result of video, specifically may include that step 215, step
217 and step 219.
One, the card generating video checks the concrete steps of result
Step 209, calculate display time of each picture frame with previously generate lock in time information difference,
Generate the time difference that each picture frame is corresponding.
Based on the server local NTP time such as present system time (System.currentTime), can
To determine each picture frame time of actual displayed when playing.When video playback, can be by each picture frame
Actual play time is relatively and this video initiates the time difference of reproduction time, generates corresponding same of each picture frame
Step temporal information.
A concrete example as the embodiment of the present invention, it is assumed that System.currentTime is 3500 millis
Second, rising between sowing time of video is 3500 milliseconds, and the display time of the 1st picture frame is 16 milliseconds, its
Actual play time be 3517 milliseconds, then information lock in time that the 1st picture frame is corresponding is 17 millis
Second；The display time of the 2nd picture frame is 48 milliseconds, and its actual play time is 3555 milliseconds,
Information lock in time that then the 2nd picture frame is corresponding is 55 milliseconds；The display time of the 3rd picture frame
Being 80 milliseconds, its actual play time is 3689 milliseconds, then during the 3rd synchronization that picture frame is corresponding
Between information be 189 milliseconds.
By calculate each picture frame display the time corresponding lock in time information difference, Ke Yisheng
Become the time difference timegaps that each picture frame is corresponding.Such as, for the 1st picture frame, this figure is calculated
As its display time 16 milliseconds of frame corresponding lock in time information 17 milliseconds difference, Ke Yisheng
The time difference timegaps becoming the 1st picture frame corresponding is 1 millisecond.In like manner, the 2nd image can be generated
The time difference timegaps that frame is corresponding is 7 milliseconds, the time difference timegaps that the 3rd picture frame is corresponding
It it is 109 milliseconds.
Step 211, judges that time difference that each picture frame is corresponding is whether in the range of reproduction time respectively.
For different definitions, Online Video is under good network transmission environment, and it plays acceptable delay.
Have says, if the picture frame of video can be play in the range of preset reproduction time, then it is assumed that this figure
As frame can be with smooth playing.It is assumed that the picture frame of video postpones to play within 40 milliseconds, can
Think that this picture frame can be with smooth playing, i.e. this picture frame is play not block and is timed.When the picture frame of video postpones
Play more than 40 milliseconds, then it is assumed that this image player card pauses.Server may determine that each figure regarding video
The time difference timegaps corresponding as frame is interior in reproduction time scope (A, B), and wherein A can
To be 0 millisecond, B can be 40 milliseconds.If the time difference timegaps that picture frame is corresponding is more than A
And during less than B, then it is believed that this presentation of video frames is smooth, otherwise to think that this frame of video card pauses.As
In above-mentioned example, the time difference timegaps 1 millisecond that the 1st picture frame is corresponding, at reproduction time model
Within enclosing (0 millisecond, 40 milliseconds), then it is believed that the 1st of this video the picture frame plays smoothness；
The time difference timegaps 109 milliseconds that 3rd picture frame is corresponding, not at reproduction time scope (0 milli
Second, 40 milliseconds) within, then it is believed that the 3rd of this video the picture frame plays card, then perform
Step 213.
Step 213, when time difference corresponding to picture frame be not in the range of described reproduction time, by described
The display time point of picture frame as card time point, generates the card of described video and pauses testing result.
When time timegaps difference corresponding to some picture frame be not in the range of reproduction time, by this figure
As the display time point of frame pauses time point as card, generate the card of described video and pause testing result.As above-mentioned
In example, time difference timegaps 109 milliseconds corresponding to the 3rd picture frame be not in reproduction time scope
Within, using the display time 80 milliseconds of the 3rd picture frame as card time point, to generate this video
Card pause testing result.
By judge video all picture frames correspondence time difference whether in the range of reproduction time, such that it is able to
Record all of card of this video to pause time point, generate the card of this video and break testing result, and then can be to right
Probability, card that during video playback, Caton phenomenon occurs are put between immediately and are added up accurately, improve detection
Degree of accuracy.
Two, the concrete steps of the frame losing testing result of video are generated
Step 215, adds up the display time of each picture frame, determines the interframe that described video is corresponding
Time difference, and each adjacent display time difference corresponding to two picture frames.
A concrete example as the embodiment of the present invention, it is assumed that during the display of each picture frame of a certain video
Between as shown in table 1.Wherein, " the 1st frame " represents the 1st picture frame；" 0x " represents employing hexadecimal
Number, as 0x00000010 represents 16.
Table 1
By adding up the display time of all picture frames of this video, it may be determined that the inter frame temporal of this video is poor
It is 32 milliseconds, and each adjacent display time difference corresponding to two picture frames, such as the 1st image
Frame and the 2nd the display time difference corresponding to picture frame are 32 milliseconds, are i.e. the aobvious of the 2nd picture frame
Show that time 0x00000030ms deducts the difference of the display time 0x00000010ms of the 2nd picture frame.
In like manner, the display time difference that other two adjacent images frames are corresponding can be calculated, as the 2nd picture frame with
3rd the display time difference corresponding to picture frame is 32 milliseconds, the 3rd picture frame and the 4th image
