Embodiments of the invention

[0080] The description paragraphs of the embodiments of the invention are entered here. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1, the first embodiment of the streaming media server performance testing method of the present invention is used to simulate the maximum number of requested video channels of the client test streaming server. The streaming media server performance testing method includes the following steps:

[0082] Step S100: Obtain an automatic test script. The test script may be input by a user, or may be obtained by automatically detecting a streaming server by an automatic detection scheme. The content of the test script can include the maximum speed of data transmission, the number of connected monitoring video devices, the type of connected device, the automatic decision process, the smoothness of user decisions, and the number of test paths initially initiated.

[0083] Step S200, calculating, according to the automatic test script, the first number of video devices accessing the streaming media server, and sending a video stream request of the first number of channels to the streaming media server; wherein, the first number of channels It can be any number, for example 1, 50 or 100, etc. It can also be from the calculation, for example, based on 60% of the number of connected devices.

[0084] Step S300, receiving a video stream of the first number of channels fed back by the streaming media server, and determining that the obtained video stream of the first channel meets the preset smooth condition, ending the current video stream request, and adding the connection The number of video devices entering the media server is a second number, and all the second number of video stream requests are sent again to the streaming server. The preset fluency condition may include a determination condition: whether the packet is lost, whether the frame loss reaches a threshold, whether the frame integrity, the frame interval reaches a threshold, or the like.

[0085] Step S400: After receiving the video stream of all the second channels fed back by the streaming media server, and determining that the obtained video stream of the second channel does not satisfy the preset smooth condition, determining the first number of channels The maximum number of requested video channels. If the video stream of the second channel is still smooth, perform more test of the number of channels until the video stream card is tested and the frame is stopped, and the number of the last smooth running is determined. The maximum number of ways. For example, when the fourth test is judged to be not smooth for the first time, the third pass of the third test is the maximum number of passes.

[0086] In the embodiment, after the determination is smooth, the number of test paths is automatically increased, and the smooth judgment is performed again, until it is determined that the flow is not smooth, the number of the last smooth state is automatically determined as the maximum number of ways; High degree of automation and high test efficiency. It should be noted that the test described in the claims is completed in the second test, only to make the description of the claim concise, and not only to protect the test in the second test, but to understand that in the subsequent In the N test, if the result is the same as the first time, the test is continued. If the result is opposite to the first time, the number of the N-1th test is the maximum number of ways.

[0087] Preferably, in order to obtain a more accurate test result, the difference between the two adjacent tests may be set to one or two. It should be noted that, after the test, the streaming media server can be connected to a plurality of monitoring video devices and obtain a real monitoring video stream; or the streaming media server and the analog test device can be connected, and the simulation test device simulates A number of monitoring video devices, and a video stream prepared for each video device.

[0088] Please refer to FIG. 2, a second embodiment of a performance testing method for a streaming media server according to the present invention. This embodiment is based on the first embodiment, and further describes step 200: Step S200, according to the automatic testing. The script calculates a first number of video devices that access the streaming media server, and the step of sending the first video stream request to the streaming media server includes:

[0089] Step S210, obtaining the speed G1 of the adapter where the streaming media server is pre-configured in the automatic test script; wherein the speed G1 may be input by the user, or may be obtained by automatically detecting the adapter according to the automatic detection scheme. of.

[0090] Step S220, obtaining a code stream size G2 of the video source file pre-configured in the automatic test script;

, Code stream size G2 can be input by the user, or it can be obtained by automatically detecting the video source file.

[0091] Step S230, obtaining a first number of paths according to the speed G1, the code stream size G2, and a preset initial load X<3⁄4, where the first path number is G1/G2*X<3⁄4, where X<3⁄4 is SOy^ Oy^ For example, when G is 1024M, M is 4

M, the initial load X% is 50%, then the first number is 128.

[0092] Step S240, sending a video stream request of the first number of channels to the streaming media server.

[0093] In this embodiment, by obtaining the speed of the adapter, and the code stream of the video source file, and calculating the first number of paths according to the initial load, the first number of paths used in the first test can be made. Connect Nearly the maximum number of passes, the effect of reducing the number of tests and improving the test efficiency.

[0094] Preferably, the preset initial load X% is 60%. Usually the initial load X% is chosen to be 60% 吋, and the test results can be obtained with fewer test times, which has the effect of improving test efficiency.

[0095] Referring to FIG. 3, a third embodiment of a performance testing method for a streaming media server according to the present invention is provided. The present embodiment is described in detail based on the second embodiment, and step S240 is specifically described. Specifically, step S240 is performed in the manner described above. The streaming server sends out the first number of video stream request steps, including:

[0096] Step S241, obtaining a device type in the automatic test script; wherein, at least a mainstream session initial protocol SIP (Session Initiation) is obtained.

Protocol), such as GB28181 devices; Real Time Streaming Protocol (RTSP), such as Onvif devices. The type and amount of equipment can be either user-entered or automatically detected based on an automatic detection scheme.

[0097] Step S242, the SIP device video and the RTSP device video are included in the automatic test script, and the initial SIP device video channel number Tl=G1/G2 is obtained according to the speed of the adapter and the code stream size G2 of the SIP device video. *X%*0.5, and the initial RTSP device video path number T2 = G1/G2'*X%*0.5 is obtained according to the speed of the adapter and the code stream size G2' of the RTSP device video. Among them, since the peers request two types of device video, each type of video can only take 1/2, so it needs to be multiplied by 0.5 in the initial load T1* X%.

[0098] Step S243: The peer sends the first path number T1 corresponding to the SIP device video and the first path number T2 corresponding to the RTSP device video to the streaming media server.

[0099] For example, when the number T1 of the initial SIP devices is 256*60%/2=76.8, the number T2 of the initial RTSP devices is 512*60%/2=153.6. Therefore, after the first time a video stream request is made to the server, the SIP device video 77 (the first method) is requested, and the RTSP device video 154 (the first method) is requested. In this embodiment, the calculation result is a non-integer, and the other method is used. In other embodiments, the rounding or the first method may be used.

[0100] In the subsequent steps, the first path number of the SIP video stream and the first path number of the RTSP video stream are respectively tested; when the first path number test result of the SIP video stream is smooth, the corresponding SIP is requested. The second number of the video stream, the second number of channels is greater than the corresponding first number of channels; when the first path number of the RTSP video stream is fluent, the second number of corresponding RTSP video streams is requested, the second The number of channels is greater than the corresponding number of channels [0101] When the subsequent second round of testing, the second number of requests for the SIP video stream and the RTSP video stream are sent, and the received video stream is tested accordingly. If the test result of the second path of the corresponding SIP video stream is smooth, request the third path of the SIP video stream; if the test result of the second path corresponding to the RTSP video stream is not smooth, determine the last time according to the subsequent steps. The first number is the maximum number of requested video channels corresponding to the RTSP video stream. And in the subsequent test, in the request for the SIP video stream, the number of requests for the RTSP video stream is always the maximum number of requested video channels until the maximum number of requested video channels of the SIP video stream is tested.

[0102] In the subsequent test, the maximum number of requested video channels corresponding to the SIP video stream and the maximum number of requested video channels corresponding to the RTSP video stream are obtained, and the entire test is ended.

[0103] In this embodiment, the SIP device video and the RTSP device video are included in the test scenario, and the request including the hybrid type can be issued, and the SIP video stream and the RTSP video stream are separately tested in the test, and then the individual can be obtained. Type of evaluation. In this embodiment, the mainstream SIP device video and the RTSP device video can be tested, and the versatility is strong. Moreover, in the scenario where the test can simulate the actual application of a complex multi-protocol device combination, more realistic test results can be obtained.

[0104] Referring to FIG. 4, preferably, the step of determining whether the video stream of the Nth path number _ the first or the second number of paths _ satisfies the preset fluency condition includes:

[0105] Step S700: Perform at least one sampling test on the video stream of the Nth channel according to a preset test configuration.

[0106] Step S710: If each of the sampling tests meets the preset fluency condition, it is determined that the obtained N-th channel video stream satisfies the preset fluency condition.

[0107] wherein, according to the performance of the current test equipment, the number of sampling tests can be 20<3⁄4~30% of the number of Nth channels, and the maximum number is 30 video streams of the same playing test; of course, after the performance of the device is improved, With more video streams to play the test, even how many video streams are requested from the streaming server, how many video streams are tested.

[0108] This section uses a test device with a maximum of 30 channels as an example to illustrate:

[0109] For example, when the number of the first way is 60 way, the test of 20% is 12 way, and the first channel of the requested video stream is tested three times, and each test selects a random 12 way of 60 channels for testing. . When the results of the three tests are all smooth, it is determined that the first number of passes satisfies the preset fluency condition. [0110] When the number of the second way is 150 way, the test of 20% of the test is 30 way; the test of the requested second number of video streams is performed three times, and each test selects 30 of the 150 channels for testing. When the results of the three tests are all smooth, it is determined that the second number of paths meets the preset fluency condition.

[0111] When the number of the third way is 300, and the test is 20%, the number is 60; for the requested second video stream, three tests are performed, and since the device limit can only test up to 30, each test is selected. Random 30 of the 300 roads were tested. When the results of the three tests are not smooth at any time, it is determined that the third number does not satisfy the preset fluency condition.

[0112] In this embodiment, by adopting the method of sampling test, the performance requirement of the test equipment is prevented from being too high, and the cost is too high.

Referring to FIG. 5, preferably, the steps of randomly sampling once in step S700 are described in detail;

[0114] Step S701: Obtain a device corresponding to the video stream requested by the Nth channel and the number M thereof, and generate a corresponding

M device numbers of the devices, and form an array ID [M].

[0115] step S702, generating a seed by using a first function for generating a seed, and generating a random integer smaller than M by calculating the seed by a second function for generating a 0~M interval random integer, and the random The integer forms an array Numbe _r [i]. Among them, the first function can use the smndO function; usually the system can be used to change the seed value of the system, namely srand(time(NULL)) _{; the} second function can use randO %M, then:

[0116] Number[i] = int (rand(srand(time(NULL)))%M)

[0117] By the above equation, a random integer smaller than the Nth channel can be obtained. For example, according to the above example, 20<3⁄4~30<3⁄4 or at most 30 random integers of the Nth number are obtained.

[0118] step S703, the ID by the [M] binding the Numbe _r [i], to obtain the device ID corresponding to the sampling number N of the number of ways [Numbe _r [i]], and in accordance with the ID [ Numbe _r [i]] is tested to obtain a single-pass test result of the Nth number.

[0119] For example, when the number of Nth channels is the first number of paths, and the number of first ways M is 15, and sampling is performed according to 20%, mnd (srand(time(NULL)))<3⁄4M obtains 1, 2, 5 three numbers, then the first ID [Number[i]] includes 1, 2, 5 three numbers, so that the video streams corresponding to number 1, number 2 and number 5 in the 15 request video streams are tested and obtained One test result. If you need to complete three tests according to the configuration, you can evaluate the first number of paths, and then follow the above steps to perform the second and third tests. [0120] Of course, in combination with the above embodiments, in the presence of multiple devices, it is possible to calculate, for each device, which videos of the numbered devices are currently required to be requested according to the method. For example, a SIP video stream requires 64 requests and an RTSP video stream requires 64 requests. Further, the device number of the random 64*20% SIP video stream is obtained by using the first function and the second function, and the device number of the random 64*20% RTSP video stream is obtained, thereby forming 13 corresponding SIP videos. Stream and test of 13 RTSP video streams.

[0121] In this embodiment, by arranging the device number, and calculating the random number of the corresponding device number by using the first function and the second function, and using the random number as the target of the sampling, the effect of the random inspection is achieved, thereby further Enhance the authenticity and improve the credibility of the test results.

[0122] Preferably, the determination of the fluency can be further limited. In the determination of whether or not the fluency condition is satisfied, the following method is used for the determination.

[0123] In the preset time, the video delay value of the video stream of the Nth number obtained is smaller than the preset video delay threshold, and the packet loss rate of the video stream of the Nth number obtained is smaller than the preset The set packet loss threshold 吋 determines that the preset fluency condition is met; otherwise, the determination does not satisfy the preset fluency condition. Preferably, the preset time interval may be 10 seconds, the video delay threshold is set to 2 seconds, and the packet loss rate threshold is set to 0.2%.

[0150] In this embodiment, it is possible to test that the video stream in the first channel is not smooth, and therefore, it has a wider range of effects. It should be noted that the improvement of any of the above embodiments can be applied to the present embodiment without any obvious conflict. For example, before the request is made, the device is proportionally distributed, random sampling is performed, local decoding is performed, and playback is performed. According to the user input, it is determined whether the flow is smooth, and whether the video delay value and the frame drop rate value are used to determine whether the flow is smooth or the like.

It should be noted that the test described in the claims is completed in the second test, only to make the description of the claim concise, and not only to protect the test in the second test, but to understand that in the subsequent In the N test, if the result is the same as the first time, the test is continued. If the result is opposite to the first time, the number of ways of the Nth test is the maximum number of ways.

[0152] Corresponding to the above method solution, the specific embodiment further provides a corresponding device solution: [0153] Referring to FIG. 8, a streaming media server performance testing device is configured to simulate a maximum number of requested video channels of a client test streaming media server. The streaming media server 1000 includes:

[0154] The input module 1100 is configured to obtain an automatic test script. The test script may be input by a user, or may be obtained by automatically detecting a streaming server by an automatic detection scheme. The content of the test script can include the maximum speed of data transmission, the number of connected monitoring video devices, the type of connected device, the automatic determination process, the smoothness of user decisions, and the number of test paths initially initiated.

[0155] The first requesting module 1200 is configured to calculate, according to the automatic test script, a first number of video devices that access the streaming media server, and control the request execution module to send a video of the first number of channels to the streaming media server. The flow request; wherein, the first way may be any number, for example 1, 50 or 100, etc., or may be from a calculation, for example, based on 60% of the number of connected devices.

[0156] The second requesting module 1300 is configured to: after receiving the video stream of the first number of channels fed back by the streaming media server, control the smoothness determining module to determine whether the video stream of the first number of channels is smooth; The first channel of the video stream meets the preset fluency condition, the current video stream request is ended, and the number of video devices accessing the streaming media server is increased to a second number, and the control request execution module sends the stream server to the streaming server. The second number of video stream requests. The preset fluency condition may include a determination condition: whether the packet is lost, whether the frame loss reaches a threshold, whether the frame integrity, the frame interval reaches a threshold, or the like.

[0157] The first determining module 1400 is configured to: after receiving the video stream of all the second channels fed back by the streaming media server, control the smoothness determining module to determine whether the video stream of the second number of channels is smooth; The video stream that obtains the second number does not satisfy the preset smooth condition, and determines that the first number of channels is the maximum number of requested video channels. If the video stream of the second channel is still smooth, the test of more channels is performed until the video stream card is tested and the frame is stopped, and the number of the last smooth running is determined as the maximum number of channels. For example, when the fourth test is judged as not smooth for the first time, the third way of the third test is the maximum number of passes.

[0158] The request execution module 1500 is configured to, when receiving the control instruction, configure to issue a video stream request according to the preset request.

[0159] The smooth judgment module 1600 is configured to determine whether the video stream satisfies the preset fluency condition after receiving the control command.

[0160] In this embodiment, after the determination is smooth, the number of test paths is automatically increased, and the smooth judgment is performed again. When it is judged that it is not smooth, it automatically judges that the number of the last smooth state is the maximum number of ways; This scheme has the effect of high automation and high test efficiency. It should be noted that the test described in the claims is completed in the second test, only to make the description of the claim concise, and not only to protect the test in the second test, but to understand that in the subsequent In the N test, if the result is the same as the first time, the test is continued. If the result is opposite to the first time, the number of the N-1th test is the maximum number of ways.

[0161] Preferably, in order to obtain a more accurate test result, the difference of the number of ways of the two adjacent tests is 1 way or 2 way. It should be noted that, after the test, the streaming media server can be connected to a plurality of monitoring video devices and obtain a real monitoring video stream; or the streaming media server and the analog test device can be connected, and the simulation test device simulates A number of monitoring video devices, and a video stream prepared for each video device.

[0162] Referring to FIG. 9, the first request module 1200 includes:

[0163] The first speed unit 1210 is configured to obtain a speed G1 of an adapter where the streaming server that is pre-configured in the automatic test script is located, where the speed G1 may be input by a user, or may be according to an automatic detection scheme. Obtained by automatically detecting the adapter.

[0164] The second speed unit 1220 is configured to obtain a code stream size G2 of the video source file that is pre-configured in the automatic test script. The code stream size G2 may be input by a user, or may automatically detect the video source file. acquired.

[0165] The number of cells 1230 is configured to obtain a first number of paths according to the speed G1, the code stream size G2, and a preset initial load X<3⁄4, where the first number of paths is G1/G2*X<3⁄4, where X<3⁄4 is SOy^ Oy^ For example, when G is 1024 M, M is 4M, and the initial load X% is 50%, the first number is 128.

[0166] The requesting unit 1240 is configured to control the request execution module 1500 to send a first channel number of video stream requests to the streaming media server.

[0167] In this embodiment, by obtaining the speed of the adapter, the code stream of the video source file, and calculating the first number of paths according to the initial load, the first number of paths used in the first test can be made. Close to the maximum number of ways, to reduce the number of tests and improve the efficiency of testing.

[0168] Preferably, the preset initial load X% is 60%. Usually the initial load X% is chosen to be 60% 吋, and the test results can be obtained with fewer test times, which has the effect of improving test efficiency.

[0169] Preferably, the requesting unit 1240 is specifically configured to: [0170] obtaining a device type in the automatic test script; wherein, at least a mainstream session initiation protocol SI P (Session Initiation) is obtained

[0171] the SIP device video and the RTSP device video are included in the automatic test script, and the initial SIP device video channel number is obtained according to the speed of the adapter and the code stream size G2 of the SIP device video. Tl=

G1/G2*X%*0.5, and the number of video channels of the initial RTSP device based on the speed of the adapter and the stream size of the RTSP device video G2' T2 = G1/G2'*X%*0.5. Among them, since the peers request two types of device video, each type of video can only take 1/2, so it needs to be multiplied by 0.5 in the initial load T1* X%.

[0172] The peer sends the first path number T1 corresponding to the SIP device video and the first path number T2 corresponding to the RTSP device video to the streaming media server.

[0173] For example, when the number T1 of the initial SIP devices is 256*60%/2=76.8, the number T2 of the initial RTSP devices is 512*60%/2=153.6. Therefore, after the first time a video stream request is made to the server, the SIP device video 77 (the first method) is requested, and the RTSP device video 154 (the first method) is requested. In this embodiment, the calculation result is a non-integer, and the other method is used. In other embodiments, the rounding or the first method may be used.

[0174] In the subsequent steps, the first path number of the SIP video stream and the first path number of the RTSP video stream are tested respectively; when the first path number test result of the SIP video stream is smooth, the corresponding SIP is requested. The second number of the video stream, the second number of channels is greater than the corresponding first number of channels; when the first path number of the RTSP video stream is fluent, the second number of corresponding RTSP video streams is requested, the first The number of two channels is greater than the number of corresponding first channels.

[0175] When the subsequent second round of testing, the peer sends out a second way request for the SIP video stream and the RTSP video stream, and performs corresponding tests on the received video stream. If the test result of the second path of the corresponding SIP video stream is smooth, request the third path of the SIP video stream; if the test result of the second path corresponding to the RTSP video stream is not smooth, determine the last time according to the subsequent steps. The first number is the maximum number of requested video channels corresponding to the RTSP video stream. And in the subsequent test, the request for the SIP video stream, the RTSP video stream The number of request paths is always the maximum number of requested video channels until the maximum number of requested video channels of the SIP video stream is tested.

[0176] In the subsequent test, the maximum number of requested video channels corresponding to the SIP video stream and the maximum number of requested video channels corresponding to the RTSP video stream are obtained, and the entire test is ended.

[0177] In this embodiment, the SIP device video and the RTSP device video are included in the test scenario, and the request including the hybrid type can be issued, and the SIP video stream and the RTSP video stream are respectively tested smoothly after the test, and then the individual can be obtained. Type of evaluation. In this embodiment, the mainstream SIP device video and the RTSP device video can be tested, and the versatility is strong. Moreover, in the scenario where the test can simulate the actual application of a complex multi-protocol device combination, more realistic test results can be obtained.

[0178] Referring to FIG. 10, the smooth judgment module 1600 includes:

[0179] The sampling unit 1610 is configured to perform at least one test on a portion of the video stream of the Nth number_first or second number _ according to a preset test configuration.

[0180] The smoothness determining unit 1620 is configured to determine that the video stream of the Nth number obtained meets the preset smooth condition if the preset smooth condition is met for each test.

[0181] wherein, according to the performance of the current test equipment, the number of sampling tests may be 20<3⁄4~30% of the number of Nth channels, and the maximum number is 30 video streams of the same playing test; of course, after the performance of the device is improved, With more video streams to play the test, even how many video streams are requested from the streaming server, how many video streams are tested.

[0182] The following is an example of a test device with a maximum of 30 channels of video as an example:

[0183] For example, when the number of the first way is 60 way, the test of 20% of the test is 12 way, and the first channel of the requested video stream is tested three times, and each of the tests selects a random 12 way of 60 channels for testing. . When the results of the three tests are all smooth, it is determined that the first number of passes meets the preset fluency condition.

[0184] When the number of the second way is 150, and the 20% of the test is 30, the test is performed three times for the requested second video stream, and each of the tests selects a random one of the 150 channels for testing. When the results of the three tests are all smooth, it is determined that the second number of paths meets the preset fluency condition.

[0185] When the number of the third way is 300, and the test is 20%, the number is 60; for the requested second video stream, three tests are performed, and since the device limit can only test up to 30, each test is selected. Random 30 of the 300 roads were tested. When the results of the three tests are not smooth at any time, it is determined that the third number is not satisfied. Preset fluency conditions.

[0186] In this embodiment, by adopting the method of sampling test, the performance requirement of the test equipment is prevented from being too high, and the cost is too high.

[0187] Preferably, a random sampling step of the sampling unit 1610 includes:

[0188] Obtaining the device corresponding to the requested video stream of the Nth channel and the number M thereof, generating a device number corresponding to the M devices, and forming an array ID [M] _; wherein the number M of devices may be a user The input can also be automatically detected according to the automatic detection scheme.

[0189] generating a seed by a first function for generating a seed, and generating a random integer smaller than M by calculating the seed by a second function for generating a 0-M interval random integer, and forming the random integer into an array Numbe _r [i] _; where the first function can use the smndO function; usually the system can be used to change the seed value of the system, namely srand(time(NULL)); the second function can use randO^M, Bay 1J:

[0190] Number[i] = int (rand(srand(time(NULL)))%M)

[0191] By using the above formula, a number of random integers smaller than the Nth channel can be obtained, for example, according to the above example,

20<3⁄4~30<3⁄4 or up to 30 random integers for the number of N channels.

[0192] by the ID [M] binding the Numbe _r [i], to obtain the corresponding N-th of the sampling device large ones ID ID [

Number[i]], and tested according to the ID [Number[i]], to obtain a single test result of the Nth number.

[0193] For example, when the number of Nth channels is the first number of paths, and the number of first ways M is 15, and sampling is performed according to 20%, then mnd (srand(time(NULL)))<3⁄4M obtains 1, 2, 5 three numbers, then the first ID [Number[i]] includes 1, 2

5 three numbers, so that the video streams corresponding to number 1, number 2 and number 5 in the 15 request video streams are tested, and a test result is obtained. If you need to complete three tests according to the configuration, you can evaluate the first number of paths, and then follow the above steps to perform the second and third tests.

[0194] Of course, in combination with the above embodiments, in the presence of multiple devices, it is possible to calculate, for each device, which videos of the numbered devices are currently required to be requested according to the method. For example, a SIP video stream requires 64 requests and an RTSP video stream requires 64 requests. Further, the device number of the random 64*20% SIP video stream is obtained by using the first function and the second function, and the device number of the random 64*20% RTSP video stream is obtained, thereby forming 13 corresponding SIP videos. Stream and test of 13 RTSP video streams.

[0195] In this embodiment, by arranging the device number, and calculating the corresponding device by using the first function and the second function The random number of the number is prepared, and the random number is used as the target of the sampling, and the effect of the random inspection is achieved, thereby further enhancing the authenticity and improving the credibility of the test result.

[0196] Preferably, the step of determining, by the smoothness determining module 1600, whether the obtained video stream of the Nth channel meets the preset fluency condition comprises:

[0197] In the preset time, the video delay value of the video stream of the Nth number obtained is smaller than the preset video delay threshold, and the packet loss rate of the video stream of the Nth number obtained is smaller than the preset value. The set packet loss threshold 吋 determines that the preset fluency condition is met; otherwise, the determination does not satisfy the preset fluency condition. Preferably, the preset time interval may be 10 seconds, the video delay threshold is set to 2 seconds, and the packet loss rate threshold is set to 0.2%.

[0198] In this embodiment, the condition for determining the smoothness is limited: in the preset time, the video delay value of the received feedback video stream is smaller than the preset video delay threshold, and is received. The packet loss rate value of the feedback video stream is smaller than the preset packet loss rate threshold 吋, and the determination meets the preset fluency condition; otherwise, the determination does not satisfy the preset fluency condition. In this embodiment, by detecting the delay value of the screen and the value of the packet loss rate, it is judged whether or not the flow is smooth, and the judgment is easy.

[0199] In order to avoid the situation that the automatic judgment fails to work normally, it is preferable to increase the standby scheme of human-computer interaction. Specifically, please refer to the following scheme.

[0200] Preferably, the streaming media server performance testing device further includes:

[0201] The playing module 1700 is configured to: after receiving the video stream fed back by the streaming server, locally decode and play the received video stream. Among them, the decoded and played image information can be transmitted through an interface for external display display; or the machine can directly play the display.

[0202] The step of determining, by the smooth judgment module 1600, whether the preset fluency condition is met specifically includes: [0203] determining that the preset smoothness is satisfied after receiving the input of the smooth and smooth evaluation of the image for local decoding and playing Condition; otherwise, it is determined that the preset fluency condition is not satisfied. Among them, the user can perform the evaluation after visual inspection, and the evaluation selects the smooth button, thereby triggering the smooth evaluation, and the determination determines that the preset smooth condition is satisfied.

[0204] In this embodiment, by providing a manual evaluation scheme, stability is enhanced, and the device is prevented from being unable to work normally and automatically cannot be operated.

[0205] In the actual test, there is also a case where the first channel video stream of the first test is not smooth, and in this case, the following scheme can be used for testing. [0206] Preferably, the second request module 1300 is further configured to: receive a video stream of the first number of channels fed back by the streaming media server, and determine that the obtained video stream of the first path does not meet the preset smoothness. Condition 吋, ending the current video stream request, and the control request execution module 1500 sends a third channel number of video stream requests to the streaming media server, wherein the third path number is less than the first path number.

[0207] The second determining module 1800 is configured to: after receiving the video stream of the third channel number fed back by the streaming media server, control the smoothness determining module 1600 to determine whether the video stream of the third channel number is smooth, The video stream obtained by the third channel satisfies the preset smooth condition, and the third channel number is determined to be the maximum number of requested video channels. In this embodiment, the video stream of the third way is used as an example, but in actual testing, there will be more tests, for example, the video stream flowing with the sixth number in the sixth time is smooth for the first time. Then, the number of sixth paths is determined to be the maximum number of ways.

[0208] In this embodiment, it is possible to test that the video stream in the first channel is not smooth, and therefore, it has a wider range of effects. It should be noted that, in the above-mentioned improvement according to the first path number and the second path number test step, in the case of no obvious conflict, the third path number test and the third way number test in this embodiment can be applied. No test results were obtained, and subsequent tests were performed after that. For example, before the request is made, the device is proportionally distributed, random sampling is performed, local decoding is performed, and playback is performed. According to the user input, it is determined whether the flow is smooth, and whether the video delay value and the frame drop rate value are used to determine whether the flow is smooth or the like.
