Embodiment two
Fig. 2 is a kind of step flow chart of protocol testing method provided by Embodiment 2 of the present invention, is applied to terminal, such as schemes
Shown in 2, this method may include:
Step 201 is monitored based on preset interface, and when listening to video data stream, from the video data stream
One message of middle acquisition, obtains sample message.
Specifically, the implementation of this step can refer to above-mentioned steps 101, therefore not to repeat here for the embodiment of the present invention.
Step 202, the value for extracting predeterminated position in the sample message, obtain reduced value.
In the embodiment of the present invention, the message that terminal obtains can be to be based on reliable transport protocol (Reliable in transmission
Transport Protocol, RTP) transmission RTP message, it is of course also possible to be the message that is transmitted based on other transport protocols,
The embodiment of the present invention is not construed as limiting this.Further, message is generally by head (Header) and load two portions (Payload)
It is grouped as.Wherein, PT Payload Type (PT) in head, can illustrate specific protocol type, and the corresponding value of different agreements is different.
Therefore, in this step, terminal can first be parsed sample message, then analytically after sample message stem in extract
The value of the corresponding agreement of sample message.Wherein, the stem of the sample message is predeterminated position, and the value extracted is to compare
Value.
If step 203, the reduced value value corresponding with the video protocols to be measured match, it is determined that the sample report
The corresponding video protocols of text match with the video protocols to be measured.
In this step, terminal can first be matched the reduced value extracted value corresponding with video protocols to be measured, such as
Both fruits match, that is, the two is identical, it may be considered that the corresponding video protocols of sample message and video protocols phase to be measured
Match, that is, be exactly, can use the message that is transmitted in the video data stream listened to as test sample to video protocols to be measured into
Row test.It is exemplary, it is assumed that the value of reduced value aaa, the corresponding value of video protocols to be measured are aaa, then sample can be determined
The corresponding video protocols of message match with video protocols to be measured.
If step 204, the corresponding video protocols of the sample message match with the video protocols to be measured, from described
At least two test packets are obtained in video data stream, and record the time point for obtaining each test packet.
In practical application, when carrying out video protocols test, if the message amount in test sample is less, it may go out
It is now unable to fully the problem of embodying video protocols performance to be measured, and if the message amount in test sample is excessive, it will make
Test quantitative change in entire test process is more, and then test process is caused to take a long time.
Therefore, in the embodiment of the present invention, terminal can first obtain view when obtaining test packet since first time point
Message in frequency data stream, and since first time point, countdown is carried out with preset duration, then, at the end of countdown,
Stop obtaining the message in video data stream, finally, the message that will acquire is determined as test packet.Wherein, the first time
Point can be current point in time, or preset time point, the embodiment of the present invention are not construed as limiting this, further, in advance
If duration can carry out the required optimal message amount maximum duration to be consumed of video protocols test, the optimal report to obtain
Literary quantity can be developer and be analyzed in formerly test in advance, test used message amount, each test result every time
Accuracy and spent time determine that the optimal message amount is not less than two, exemplary, the optimal message amount
It can be 800, correspondingly, developer can determine by experiment and receive the maximum time that 800 messages need to expend, so
The maximum time is determined as preset duration afterwards, to guarantee that terminal can get the survey of optimal message amount in preset duration
Try message.In this way, only pass through the standard using preset duration as countdown and carry out countdown, can controlling terminal get most
The test packet of excellent message amount, meanwhile, by the way that the quantity control of test packet in optimal message amount, can guaranteed to assist
While discussing the accuracy of test, by test volume control in suitable quantity, guarantees that test process is bad and expend the too long time.
Further, terminal is also possible to first obtain video data stream since first time point when obtaining test packet
In message, then, the message got quantity be equal to preset quantity when, stop obtain video data stream in message,
The message that finally will acquire is determined as test packet.Wherein, preset quantity is optimal report needed for carrying out video protocols test
Literary quantity.Specifically, terminal can be from the quantity of message accessed by first time point start recording, in quantity not less than pre-
If stopping obtaining operation when quantity, required amount of test packet is got in this way, terminal can be more accurate, meanwhile, lead to
It crosses the quantity control of test packet in optimal message amount, can will be tested while the accuracy that guarantee agreement is tested
Amount control guarantees that test process is bad and expends the too long time in suitable quantity.
Further, terminal can call preset time generating function to utilize this when getting each test packet
Time generating function records the time point for getting the test packet.
Step 205, the time point based at least two test packet and each test packet of acquisition, generate test
Message data.
Specifically, this step can be realized by following sub-steps (1)~sub-step (4):
Sub-step (1): being determined as the first test packet for the last one test packet, will except first test packet it
Outer test packet is determined as the second test packet.
It is exemplary, it is assumed that obtain 4 test packets, this 4 test packets are according to by the early acquisition sequence difference to evening
Are as follows: test packet 1, test packet 2, test packet 3 and test packet 4.So, test packet 4 can be determined as by terminal
First test packet, by the test packet in addition to test packet 4, that is, test packet 1, test packet 2, test packet 3 is true
It is set to the second test packet.
Sub-step (2): for each second test packet, the time point for obtaining second test packet and acquisition are calculated
The absolute value of the difference at the time point of next test packet of second test packet obtains second test packet pair
The first time interval answered.
In this step, for test packet 1, next test packet of test packet 1 is test packet 2, therefore can be with
It calculates the time point for obtaining test packet 1 and obtains the absolute value of the difference at the time point of test packet 2, obtain test packet 1
Corresponding first time interval；For test packet 2, next test packet of test packet 2 is test packet 3, therefore can
To calculate the time point and the absolute value of the difference at the time point for obtaining test packet 3 that obtain test packet 2, test packet is obtained
2 corresponding first time intervals；For test packet 3, next test packet of test packet 3 is test packet 3, therefore can
To obtain the absolute value of the difference at the time point of test packet 3 and the time point of acquisition test packet 4, it is right to obtain test packet 3
The first time interval answered.
Sub-step (3): between second test packet first time interval corresponding with second test packet
Separator is set.
In this step, which can be used for separating the second test packet first time corresponding with the second test packet
Interval, exemplary, which can be the constant of a nybble.In the embodiment of the present invention, by the second test packet
Separator is set between time interval corresponding with the second test packet, it is ensured that the second test packet is corresponding
When first time interval is stored together, terminal will not obscure the corresponding first time interval of the second test packet, be convenient for
Terminal differentiates data.
Sub-step (4): by second test packet, the separator and second test packet corresponding first
Time interval is stored as same data, and directly stores first test packet, obtains the test packet data.
It is exemplary, it is assumed that the corresponding time interval of test packet 1 is A milliseconds, the corresponding first time of test packet 1
The separator being arranged between interval is " 001 ", and the corresponding time interval of test packet 2 is B milliseconds, and test packet 2 is corresponding
First time interval between the separator that is arranged be " 002 ", the corresponding time interval of test packet 3 is C milliseconds, test packet
The separator being arranged between 3 corresponding first time intervals is " 003 ", then terminal can be according to as shown in table 1 below
Mode is stored, and test packet data are obtained:
| 1 001A of test packet |
| 2 001B of test packet |
| 3 001C of test packet |
| Test packet 4 |
Table 1
In this step, terminal can close corresponding file handle, wherein file after generating test packet data
Handle indicate obtain data when serial number, due to test packet be all obtained from the video data stream listened to, and
After generation test packet data, it is believed that no longer need to obtain test packet, therefore, terminal can generate test packet number
According to later, corresponding file handle can be closed, avoids wasting unnecessary resource.
Step 206 is based on the test packet data, tests the video protocols to be measured.
In this step, terminal can use the transmission simulator disposed in terminal and receive simulator and tested, and have
Body, terminal can be realized by following sub-steps (5)~sub-step (8) is based on test packet data, to video protocols to be measured
It is tested:
Sub-step (5): utilizing the transmission simulator according to the corresponding first time interval of each second test packet, will
Each test packet in the test packet data is sent to the reception simulator.
Specifically, terminal can be according to acquisition each second for the second test packet of each of test packet data
Second test packet is sent to the reception simulation at the second time point using simulator is sent by the time sequencing of test packet
Device.Then, next test packet of the second test packet is sent to reception mould at third time point using transmission simulator
Quasi- device, until receiving simulator until the first test packet in test packet data to be sent to；Wherein, third time point with
Time interval between second time point is equal to the corresponding time interval of the second test packet, which can be current
Time point, or preset time point, the embodiment of the present invention are not construed as limiting this.
Exemplary, terminal, which can use, sends simulator according to the storage format in aforementioned table 1, by separator in the first row
Part before, that is, test packet 1 is sent to receipts simulator, after A milliseconds, test packet 2 is sent to receipts simulation
Test packet 3 correspondingly after B milliseconds, is sent to receipts simulator by device, correspondingly, after C milliseconds, by test packet
4 are sent to receipts simulator, since test packet 4 is the first test packet, can determine at this time all in test packet data
Test packet has been sent, and can stop sending operation at this time.
Sub-step (6): receiving each test packet that the transmission simulator is sent using the reception simulator, and
Record receives the time point of each test packet.
It is exemplary, it can use and receive test packet 1, test packet 2, test that simulator receives transmission simulator transmission
Message 3 and test packet 4, and record the time point for receiving test packet 1, the time point for receiving test packet 2, receive
To test packet 3 time point and receive time point of test packet 4.
Sub-step (7): for each of receiving the second test packet, institute is received using reception simulator calculating
State the difference at the time point and the time point for the next test packet for receiving second test packet of the second test packet
Absolute value, obtain corresponding second time interval of second test packet.
In this step, for the second test packet " test packet 1 ", due to next test packet of the test packet 1
For test packet 2, therefore the difference for receiving the time point of test packet 1 and receiving the time point of test packet 2 can be calculated
The absolute value of value obtains corresponding second time interval of test packet 1；For the second test packet " test packet 2 ", due to this
Next test packet of test packet 2 is test packet 3, therefore can calculate and receive time point of test packet 2 and connect
The absolute value for receiving the difference at the time point of test packet 3 obtains corresponding second time interval of test packet 2；For second
Test packet " test packet 3 " can be calculated and be connect since next test packet of the test packet 3 is test packet 4
Time point and the absolute value of the difference at the time point for receiving test packet 4 for receiving test packet 3, it is right to obtain test packet 3
The second time interval answered.
Sub-step (8): utilize the reception simulator based on the corresponding first time interval of each second test packet, often
