S102: the play parameter this time increased after playing is determined.
As an implementation, the brightness and coloration of data block in video frame played after playing can be increased this It is analyzed, result will be analyzed as this and increase the play parameter after playing.
For example, one or more video frames can be extracted in the video flowing played after this increases and plays, for The each video frame extracted, to the YUV of each data block in the video frame (Y indicates brightness, and U and V indicate coloration) component into Row analysis will analyze result as this and increase the play parameter after playing.
In other embodiments, play parameter can there are many, such as the delayed data, the picture that occur in playing process Exception information, data packet serial number exception information etc., correspondingly, determine there are many modes of play parameter, below in content into Row is described in detail.
S103: judging whether the play parameter meets exceptional condition, if so, executing S104, executes if not, returning S101。
In the present embodiment, exceptional condition is set for play parameter in advance, for example, the exceptional condition can be with are as follows: prolongs When information be greater than threshold value, abnormal data packet quantity is greater than threshold value, etc., below be described in detail in content.
S104: this is increased to the video flowing number that the video flowing number played before playing is determined as equipment support.
In embodiments of the present invention, if play parameter is still unsatisfactory for exceptional condition, then after increasing the broadcasting road N video flowing It continues growing and plays the road N video flowing, until play parameter meets exceptional condition after certain increases the broadcasting road N video flowing, then should The secondary video flowing number for increasing the video flowing number played before playing and being determined as equipment support.
N can be a fixed numbers, such as 1 or 2, or may be other positive integers, specifically without limitation.It is with 1 For example, increase play 1 road video flowing every time, it is assumed that play parameter is unsatisfactory for exceptional condition when playing 3 road video flowing, and increase is broadcast Play parameter meets exceptional condition after putting 1 road video flowing, that is, when playing 4 road video flowing, this time increases play before play Video flowing number be 3, equipment support video flowing number be 3.
Alternatively, N can also be not fixed, that is to say, that increasing the video flowing number played every time can be different, for example, first Secondary increase plays 3 road video flowings, and determines that play parameter is unsatisfactory for exceptional condition after increasing broadcasting for the first time, increases for the second time 2 road video flowings are played, and determine that play parameter is also unsatisfactory for exceptional condition after increasing broadcasting second, third time, which increases, to be played 1 road video flowing, play parameter meets exceptional condition after determining third time increase broadcasting, and third time increases the view for playing broadcasting before Frequency flow path number is 3+2, and the video flowing number that equipment is supported is 5.

It is below that the embodiment that reduction plays the road N video flowing every time is described in detail to adjustment mode.
Fig. 3 is second of process signal for the method that determining equipment provided in an embodiment of the present invention supports video flowing number Figure, comprising:
S301: reducing and play the road N video flowing, and the N is positive integer.
Before executing the present embodiment, the road X video flowing is playing in Devices to test, X is preset value, and X is greater than The video flowing number that Devices to test is supported, X are the positive integer greater than N.
It is appreciated that not can determine that Devices to test supports the specific number of video flowing number before executing the present embodiment Value, but can determine a rough range, a rough order of magnitude can be determined in other words, it can be according to the rough model It encloses and X is set.For example, the video flowing number for predefining Devices to test support can then set X substantially between 5-15 It is set to 20 or other numerical value, specifically without limitation.
For example, video flowing can be preview video stream, or playback video flowing.Preview video stream can be figure As the video flowing that acquisition equipment acquires in real time, playback video flowing can be the video flowing stored in storage server.It can in S301 To reduce the preview video stream for reading image capture device acquisition, the playback video for reading storage server storage can also be reduced Stream.
Than as shown in Figure 2, Devices to test is connected with more IP Camera and storage server, and Devices to test both can be with The preview video stream for reading IP Camera acquisition is reduced, the playback video flowing for reading storage server storage can also be reduced.
S302: the play parameter this time reduced after playing is determined.
As an implementation, the brightness and coloration of data block in the video frame played after playing can be reduced to this It is analyzed, result will be analyzed as this and reduce the play parameter after playing.
For example, one or more video frames can be extracted in the video flowing played after this reduces and plays, for The each video frame extracted, to the YUV of each data block in the video frame (Y indicates brightness, and U and V indicate coloration) component into Row analysis will analyze result as this and reduce the play parameter after playing.
In other embodiments, play parameter can there are many, such as the delayed data, the picture that occur in playing process Exception information, data packet serial number exception information etc., correspondingly, determine there are many modes of play parameter, below in content into Row is described in detail.
S303: judging whether the play parameter meets exceptional condition, executes S301 if so, returning, if not, executing S304。
In the present embodiment, exceptional condition is set for play parameter in advance, for example, the exceptional condition can be with are as follows: prolongs When information be greater than threshold value, abnormal data packet quantity is greater than threshold value, etc., below be described in detail in content.
S304: this is reduced to the video flowing number that the video flowing number played after playing is determined as equipment support.
In embodiments of the present invention, if reduce play the road N video flowing after, play parameter still meets exceptional condition, then after Continuous reduce plays the road N video flowing, until certain, which reduces play parameter after playing the road N video flowing, is unsatisfactory for exceptional condition, then should The secondary video flowing number for reducing the video flowing number for playing and playing later and being determined as equipment support.
N can be a fixed numbers, such as 1 or 2, or may be other positive integers, specifically without limitation.It is with 1 It for example, reduces play 1 road video flowing every time, it is assumed that play parameter meets exceptional condition when playing 4 road video flowing, reduces and plays Play parameter no longer meets exceptional condition after 1 road video flowing, that is, when playing 3 road video flowing, this time is reduced play after broadcasts The video flowing number put is 3, and the video flowing number that equipment is supported is 3.
Alternatively, N can also be not fixed, that is to say, that reducing the video flowing number played every time can be different.For example, X is 10,10 road video flowing of Devices to test initial play reduces play 3 road video flowings for the first time, that is, plays 7 road video flowings, sentences Play parameter still meets exceptional condition after the fixed broadcasting of reduction for the first time；Second of reduction plays 2 road video flowings, that is, plays 5 Road video flowing determines that play parameter still meets exceptional condition after reducing broadcasting second, and third time, which is reduced, plays 1 road video flowing, 4 road video flowings are namely played, play parameter no longer meets exceptional condition after determining third time reduction broadcasting, and third time is reduced and broadcast The video flowing number played after putting is 4, and the video flowing number that equipment is supported is 4.
Using embodiment illustrated in fig. 3 of the present invention, Devices to test is reduced every time plays the road N video flowing, and judgement is this time reduced and broadcast Whether the play parameter after putting meets exceptional condition；If still met, continues to reduce playing the road N video flowing, continue judgement and subtract Whether the play parameter after few broadcasting meets exceptional condition；If this time reducing the play parameter after playing is unsatisfactory for abnormal item This is reduced the video flowing number that the video flowing number played after playing is determined as the support of this equipment by part；As it can be seen that this programme In, without the concern for the various factors for influencing equipment support video flowing number, it is only necessary to which equipment adjust automatically plays video stream It is several, whether extremely to judge automatically after adjusting, first aspect process is simple, improves efficiency, and second aspect realizes automatic test, It does not need manually to participate in, the third aspect, sets exceptional condition in this programme, if play parameter adjusted meets exceptional condition, Then determine exception after adjusting, exceptional condition can be adjusted according to actual scene, in other words, to intensity of anomaly in this programme Tolerance be it is adjustable, this programme is preferable to the adaptability of different scenes.
In Fig. 1 and embodiment illustrated in fig. 3, the play parameter after this time adjusting and (increasing to play or reduce and play) is determined, And judge whether the play parameter meets exceptional condition can be there are many judgment mode, for example:
The first judgment mode determines the delayed data occurred in playing process after this time adjusting, after this adjustment Play parameter, judge whether the delayed data is less than delay threshold, if it is less, it is different to determine that the play parameter is unsatisfactory for Normal condition.
As an implementation, every road video flowing for playing after this being adjusted and preset time baseline carry out pair Than determining the delayed data occurred in playing process after this time adjusting according to comparing result.For example, video will can be received The time interval of data packet and the step-length of the preset time baseline are made poor in stream, and whether the difference judged is less than delay threshold Value, if it is lower, foot exceptional condition with thumb down.
The delay threshold can be set according to the actual situation, such as the situation lower in some delay tolerances In, which is set it is smaller, such as 1 second, and in the higher situation of some delay tolerances, by the delay threshold What is set is more larger, which is usually more than the time tolerance between two adjacent video frames.
Second of judgment mode, judge to determine this time adjust after whether occur picture exception information in playing process, and will Judging result is as this play parameter adjusted, that is to say, that if occurring picture exception in playing process, determines this Secondary play parameter adjusted meets exceptional condition.
It as an implementation, can be to the brightness and coloration progress of data block in the video frame played after this adjustment Analysis judges whether the video frame is abnormal, if the video frame is abnormal, determines occur picture in playing process based on the analysis results Face is abnormal.
For example, one or more video frames can be extracted, for extraction in the video flowing played after this adjustment Each video frame, the YUV of each data block in the video frame (Y indicates brightness, and U and V indicate coloration) component is divided Analysis judges whether the video frame is abnormal based on the analysis results, determines occur picture in playing process if the video frame is abnormal It is abnormal.
For example, can be with each GOP (Group of Pictures) one video frame of decimation in time.In general, one If there is a video frame picture is abnormal in GOP, then the subsequent video frame in the GOP is all abnormal.Therefore, every GOP extracts one Video frame can accurately judge whether picture exception occur.
Alternatively, a threshold value can be set if having extracted multiple video frames, reach the threshold value in the quantity of anomalous video frame In the case where, determine occur picture exception in playing process.
The third judgment mode, the data packet serial number exception information whether occurred in playing process after judgement this time adjusts, And using judging result as this play parameter adjusted, that is to say, that if there are data packet serial number is different in playing process Normal situation then determines that this time play parameter adjusted meets exceptional condition.
The case where the case where situation of data packet serial number exception may include lost data packets, data packet disorder etc..Data Packet serial number is tactic, an act simply example, it is assumed that the number of data packet serial number 0-100 cycle arrangement, if gone out The case where existing serial number interruption, for example, after receiving the data packet of serial number 50, and continue to serial number 52,53 and it Data packet afterwards, then it represents that the data-bag lost of serial number 51；For another example, after the data packet for receiving serial number 50, and after Continued access receives serial number 52,51 and data packet later, then it represents that the data packet of serial number 51 and the data packet of serial number 52 are suitable Sequence is reverse, that is, out-of-order situation has occurred.In this case, it is possible to determine that this time play parameter adjusted meets abnormal Condition.
(the first sample mode) as an implementation determines this time play parameter adjusted, may include: pair The video flowing played after this time adjusting carries out default second quantity time sampling, and sampling obtains a sampled data every time；For institute Whether abnormal every part of obtained sampled data judges this part of sampled data, and counts the number of abnormal sample data, as this Play parameter adjusted；
Judge whether the play parameter meets exceptional condition, may include: the abnormal sample data that judgement statistics obtains Number whether be greater than default second threshold, if so, determining that the play parameter meets exceptional condition.
In the present embodiment, it is sampled for the video flowing played after this adjustment, specifically, can be to broadcasting It is all sampled per video flowing all the way, perhaps the video flowing played only can also be increased to this and sampled or can also be with The stochastical sampling in the multi-path video stream of broadcasting, specifically without limitation.
It can use the first above-mentioned judgment mode, second of judgment mode, any one in the third judgment mode is come It determines this time play parameter adjusted, and judges whether the play parameter meets exceptional condition；Alternatively, can also be by these three Judgment mode is combined to judge whether play parameter meets exceptional condition, such as a sampled data, first determines it Delayed data, then judge whether it picture exception occurs, if delayed data is less than delay threshold and determines that not occur picture different Often, then determine that this part of sampled data be not abnormal；The combination of above-mentioned several judgment modes without limitation, can with combination of two, It can also be combined with three kinds of judgment modes, built-up sequence is without limitation.
For example, it may include a video frame in a sampled data, if utilizing above-mentioned second of judgment mode Judge whether sampled data abnormal, can brightness to the data block in a video frame in the sampled data and coloration carry out Analysis judges whether the video frame is abnormal, if the video frame is abnormal, determines this part of sampled data exception based on the analysis results.
Second threshold in present embodiment can be a fixed value, be also possible to unfixed.For example, can deposit in advance The corresponding relationship for storing up video flowing number and threshold value first determines the video flowing number played after this time adjusting according to the corresponding relationship Corresponding second threshold, then judge whether the number for the abnormal sample data that statistics obtains is greater than identified second threshold.It should Corresponding relationship can be set according to the actual situation.
Using present embodiment, judge whether play parameter meets exceptional condition, not by once being sentenced Break as a result, but multiple repairing weld, multiple judgement can reduce interference of the occasional case to judging result, judging result is more in this way Accurately.
(second of sample mode) as another embodiment determines this time play parameter adjusted, may include:
The video flowing played after this is adjusted is divided into the timeslice of preset length；
For each timeslice, default first quantity time sampling is carried out, sampling obtains a sampled data every time；Judgement is every Whether part sampled data is abnormal, and counts the number of abnormal sample data in the timeslice；If counting obtained number to be greater than in advance If first threshold, then timeslice exception is determined；
Abnormal timeslice quantity is counted, as this play parameter adjusted；
Judge whether the play parameter meets exceptional condition, may include:
Whether the abnormal timeslice quantity for judging that statistics obtains is greater than preset first threshold value, if so, broadcasting described in determining It puts parameter and meets exceptional condition.
For example, one minute video flowing can be divided into a timeslice, 10 are carried out to video flowing per minute Secondary sampling.The specific length of timeslice and the sampling number of each timeslice can be set according to the actual situation, specifically Without limitation.
Can be to the division for all carrying out timeslice per video flowing all the way of broadcasting, or only this can also be increased and played Video flowing carry out the division of timeslice, or the division of timeslice can also be carried out at random in the multi-path video stream of broadcasting, Specifically without limitation.To simplify the description, it is only illustrated for dividing timeslice to video flowing all the way below.
In the present embodiment, after being adjusted every time to currently playing video flowing number, a period can be reserved To judge playing whether exception occur after this time adjusting.Assuming that the period is 5 minutes, it is assumed that divide one minute video flowing For a timeslice, that is, 5 timeslices are divided, has needed to judge whether this 5 timeslices exception occur.Set a threshold Value, it is assumed that be 3, if the quantity of abnormal time piece is more than threshold value 3, judgement plays after this time adjusting exception occurs.
For example, judge whether each timeslice occurs abnormal may include: to assume to carry out each timeslice 10 times Sampling sets a threshold value, it is assumed that and it is 5, if in 10 sampled datas of a timeslice, if the quantity of abnormal sample data More than threshold value 5, then it is abnormal to determine that the video flowing of the timeslice occurs.
It can use the first above-mentioned judgment mode, second of judgment mode, any one in the third judgment mode is come Judge whether a sampled data is abnormal；Alternatively, these three judgment modes can also be combined to judge a hits According to whether extremely, such as a sampled data, first judge whether its delayed data is less than delay threshold, then whether judge it It is abnormal to there is picture, in the case that judging result is all no twice, determines that this part of sampled data be not abnormal；The combination of judgment mode Mode without limitation, can also be combined, built-up sequence is without limitation with combination of two with three kinds of judgment modes.Citing comes It says, may include a video frame in a sampled data, if judging that sampled data is using above-mentioned second of judgment mode No exception, can brightness to the data block in a video frame in the sampled data and coloration analyze, according to analysis As a result judge whether the video frame is abnormal, if the video frame is abnormal, determines this part of sampled data exception.
The second preset threshold in present embodiment can be a fixed value, be also possible to unfixed.For example, can be pre- The corresponding relationship for first storing video flowing number and threshold value first determines the video flowing played after this time adjusting according to the corresponding relationship Whether the corresponding first threshold of number, then the abnormal timeslice quantity for judging that statistics obtains are greater than identified first threshold. The corresponding relationship can be set according to the actual situation.
Using present embodiment, judge whether play parameter meets exceptional condition, not by once being sentenced Break as a result, but multiple repairing weld, multiple judgement can reduce interference of the occasional case to judging result, judging result is more in this way Accurately.
Judging whether this play parameter adjusted meets the embodiment party of exceptional condition above by multiple repairing weld In formula, if detecting network interruption in the judgment process, this time play parameter adjusted is redefined, this is rejudged Whether play parameter meets exceptional condition.
As an example it is assumed that N is 1, increase plays video flowing all the way every time, this time increases to play and broadcast for the 4th increase It puts, plays three road video flowings before increasing, four road video flowings are played after increase, 5 minutes are reserved after increase to determine the 4th increase Play parameter after broadcasting, and judge whether the play parameter meets exceptional condition.
In this 5 minutes, any one in above two embodiment (two kinds of sample modes) can use, to video flowing It is sampled, and counts the quantity of abnormal sample data, or the quantity of statistics abnormal time piece, the quantity obtained according to statistics Whether the play parameter for judging that the 4th time increases after playing meets exceptional condition.
If after increasing and play at the 4th time, until obtaining judging result (judges the 4th broadcasting ginseng increased after playing Whether number meets the judging results of exceptional condition) before any moment, detect network interruption, all re-execute determining broadcasting Parameter and judge whether play parameter meets the process of exceptional condition.Specifically, being returned in a kind of above-mentioned embodiment The step of " default second quantity time sampling is carried out to the video flowing of broadcasting "；In above-mentioned another embodiment, return to The step of " video flowing of broadcasting is divided into the timeslice of preset length ".
As another example, it is assumed that N 1 is reduced play video flowing all the way every time, is this time reduced to play to reduce for third time and be broadcast It puts, plays four road video flowings before reducing, three road video flowings are played after reduction, 5 minutes are reserved after reduction to determine that third time is reduced Play parameter after broadcasting, and judge whether the play parameter meets exceptional condition.
In this 5 minutes, any one in above two embodiment (two kinds of sample modes) can use, to video flowing It is sampled, and counts the quantity of abnormal sample data, or the quantity of statistics abnormal time piece, the quantity obtained according to statistics Whether the play parameter for judging that third time is reduced after playing meets exceptional condition.
If after third time is reduced and played, until obtaining judging result, (judgement third time reduces the broadcasting ginseng after playing Whether number meets the judging results of exceptional condition) before any moment, detect network interruption, all re-execute determining broadcasting Parameter and judge whether play parameter meets the process of exceptional condition.Specifically, being returned in a kind of above-mentioned embodiment The step of " default second quantity time sampling is carried out to the video flowing of broadcasting "；In above-mentioned another embodiment, return to The step of " video flowing of broadcasting is divided into the timeslice of preset length ".
